Fat oxidation benefits -

The placement of hands and feet on the elliptical were standardized for all participants. The gradient was maintained at a midpoint between the low to high ranges, pre-determined on the elliptical, and was maintained throughout the entire test Dalleck et al.

Every three minutes, the power output was increased by 20 W until participants reached an RER of 1. Power output was then increased by 20 W every minute until V̇O 2peak was reached.

Participants were required to maintain the appropriate exercise intensity by keeping the average power output at the target value. Rowing Exercise ROW. An adapted incremental V̇O 2peak exercise protocol was used to ensure that there was a sufficient number of stages to build substrate oxidation curves Egan et al.

Participants began rowing at 30 W for the first three-minute stage on the rower Model D Rowing Ergometer, Concept2 Inc. To standardize the level of drag for all participants, the coefficient of drag was maintained at during all subsequent stages Egan et al.

The power output was increased by 30 W every three minutes until participants reached an RER of 1. Power output was then increased by 30 W every minute until V̇O 2peak was reached.

For exercise on all three modalities, V̇O 2 was considered to be peak when at least two of the three following conditions occurred, 1 if heart rate did not significantly increase with increasing workload defined as an increase of no more than 5 bpm , 2 if RER was greater than 1.

Heart rate HR was recorded continuously using a Polar Heart Rate Monitor H Fingertip blood samples were collected using a contact-activated lancet BD Microtainer, BD, USA prior to, and immediately following, each exercise session to assess blood lactate Lactate Pro Test Strip, Arkray, Kyoto, Japan and glucose FreeStyle Precision Neo, Abbott Point of Care, Illinois, USA concentrations.

Venous blood samples, from an antecubital vein, were also collected prior to, and immediately following each exercise session to assess concentrations of pH levels, base excess of extracellular fluid BEecf , bicarbonate levels HCO 3 - , partial pressure of oxygen pO 2 , partial pressure of carbon dioxide pCO 2 , total carbon dioxide levels TCO 2 , and oxygen saturation SO 2 i-STAT Handheld, Abbott Point of Care, Illinois, USA.

Breath-by-breath cardiorespiratory data were collected continuously during exercise using an open circuit ergospirometer in breath-by-breath mode CPX, MGC Diagnostics, Saint Paul, MN to obtain measures of oxygen consumption V̇O 2 , carbon dioxide production V̇CO 2 , respiratory exchange ratio RER , and ventilation rate V̇E.

Gas flow was measured through a bidirectional pitot tube flow sensor attached to the face-fitting mask worn by all participants during the exercise sessions. For each three-minute stage of the V̇O 2peak protocols, the last thirty seconds was averaged for the following measures: HR, V̇O 2 , V̇CO 2 , and V̇E.

The highest mean value over the entire exercise protocol for both HR and V̇E was used to determine peak heart rate HR peak , and peak ventilation rate V̇E peak values for each participant. Protein oxidation was not directly calculated as short-term exercise does not alter its contribution Vallerand and Jacobs, Normal distribution of the data was verified via skewness and kurtosis tests, Kolmogorov-Smirnov and Shapiro-Wilk tests, and visual inspection of histograms.

When a significant F ratio was observed, pairwise comparisons with Bonferroni correction was conducted. Statistical analyses were completed using SPSS statistical package Version 24, IBM, Armonk, NY, Mean MFO was higher in TM vs.

Similarly, Fat max was higher in TM vs. Figure 2 presents absolute rates of fat and CHO oxidation across the exercise intensity spectrum during treadmill, elliptical and rower exercise.

Examination of the fat oxidation curves revealed that curves became linear, and the distribution of the data was greater in the elliptical and rower exercises. The CHO oxidation curves were similar in shape between exercise modalities, but a greater distribution of the data was found in the elliptical condition.

Results of the regression model for the relative fat and CHO oxidation are presented in Table 1. Additionally, pO 2 was higher post-exercise in TM vs.

BEecf was also significantly lower post-exercise during ROW exercise compared vs. Mean TCO 2 was significantly lower post-exercise The present study investigated the influence of whole-body exercises, including treadmill, elliptical, and rower exercise, on fat oxidation parameters in healthy individuals.

The main findings of this study were: i MFO and Fat max were higher during the treadmill condition compared to both the elliptical and rower conditions, ii there was no difference in crossover points between the three conditions, and iii exercise modality influenced absolute rates of CHO and fat oxidation, and thereby modulated their respective curves across the exercise intensity spectrum.

The present study supports previous work demonstrating that treadmill exercise results in higher MFO rates than other exercise modalities, and greater metabolic benefits may stem from walking and running exercise Achten et al. This work provides critical metabolic insights that may promote further research focused on those suffering from metabolic conditions and physical disabilities.

V̇O 2peak values were similar between all three exercise modalities. Maximal V̇O 2 values reflect the quantity of active muscle mass during exercise, indicating that all three modalities elicited similar levels of muscle activation. Previous research has identified level of active muscle mass as a mechanism for differences in fat oxidation, particularly between cycling and other whole-body modalities.

Achten et al. Walking and running on a treadmill utilizes different muscle contraction regimes and elicits greater mechanical efficiency compared to cycling, which may be extended to include elliptical and rowing exercise. Additionally, the return of elastic energy may reduce recruitment of larger motor units consisting of greater Type II muscle fibres, influencing CHO metabolism, lactate production, and onset of peripheral fatigue Carter et al.

Egan et al. However, the mean MFO rates and Fat max values in the present study were lower on the rowing ergometer than Egan et al.

Modality-specific training status is highly correlated with MFO and metabolic efficiency, promoting greater fat oxidation Hagerman, The present study used healthy males with no explicit training in rowing, while Egan et al.

However, this study was designed to provide information for, and reflect how recreational individuals respond to different exercise modalities. Despite this, the lack of familiarization and training with alternative whole-body exercises, particularly during rowing, may have led to decreased efficiency and greater reliance on the muscles of the upper body compared to those who utilize these modalities more often.

While untrained rowers display similar muscle synergies spatiotemporal pattern of muscle activation as trained rowers Shaharudin and Agrawal, , body posture and stroke technique can vary greatly between trained and untrained rowers Cerne et al.

Secher also detailed that untrained individuals will utilize less upper body movement and focus on the drive of the legs during rowing strokes with increased training. Therefore, even though similar levels in activation of muscle mass occurred between exercise modalities, as indicated by similar V̇O 2peak values, the specific muscles utilized for each modality may explain differences in fat oxidation.

Moreover, the lower MFO and Fat max in elliptical and rower vs. treadmill could be associated with an increased recruitment of Type II muscle fibers Achten et al. The present study demonstrated higher blood lactate concentrations post-exercise in both the elliptical and rowing conditions.

Type II muscle fibres are less efficient than Type I muscle fibers since they rely primarily on carbohydrates as their energy source and produce lactate as a by-product Knechtle et al.

Treadmill exercise primarily uses muscles of the lower extremities, such as the gastrocnemius Sozen, , composed of a high percentage of Type I fibres Costill et al. The elliptical and rower involve greater activation of many muscles of the upper body compared to the treadmill Bazzucchi et al.

Although not all of the muscles of the upper body are mainly composed of Type II muscle fibres, the muscles of the upper limbs i.

Biceps Brachii, Triceps Brachii have been known to have a greater percentage of these fibres Klein et al. Finally, these muscles also generally have a smaller surface area than those of the lower body Young et al.

The increased reliance on muscles of the upper body, and subsequently Tyle II muscle fibres, may have influenced the overall fat oxidation curves for elliptical and rowing exercises Figure 2.

Visually, curve fitting demonstrated a loss of curvilinearity of the fat oxidation curves in the elliptical and rowing exercise, as the apex of the curve i. the point of maximal fat oxidation occurred at low exercise intensities.

Fat max values for elliptical and rowing exercises were similar to those observed in overweight Bogdanis et al. The reduced ability of muscles to oxidize fat observed in obesity is suggested to result from increased intracellular lipid accumulation, leading to production of reactive oxygen species and disruption of mitochondiral oxidative enzymes Wells et al.

Therefore, factors such as exercise modalitiy and body weight, can heavily influence intrinsic cellular processes in skeletal muscle, altering substrate metabolism in these tissues. The accumulation of lactate, and subsequent decrease in pH, lowers fatty acid oxidation with increasing exercise intensities Achten and Jeukendrup, as they are known to inhibit long-chain fatty acid entry into the mitochondria Sidossis et al.

Lower muscle pH decreases the activity of carnitine palmitoyl transferase 1 CPT-1 , responsible for transporting long-chain fatty acids into the mitochondria Starritt et al.

Even though we did not observe a difference in plasma pH at the end of exercise between modalities, lactate concentrations were different between treadmill and rower, and it has been suggested that plasma lactate concentrations reflect changes in muscle pH MacLean et al.

Our results further substantiate this response with higher base excess of extracellular fluid in the treadmill and elliptical compared to the rower condition.

Previous research has shown that the lactate threshold occurs at a lower V̇O 2 during incremental rowing exercise compared to treadmill, even when the same V̇O 2max is attained Weltman et al.

Blood lactate increases in a curvilinear fashion with increasing exercise intensity, resulting in an exponential increase during work above the lactate threshold Goodwin et al. The onset of blood lactate accumulation is also highly correlation with the onset of muscle deoxygenation Grassi et al.

The potential for increased lactate accumulation at an earlier stage lower V̇O 2 during rowing exercise may have resulted in a prompter shift in metabolism, and therefore a higher concentrations of lactate at the end of exercise compared to the treadmill.

Interestingly, a higher venous partial pressure of O 2 was observed in the treadmill condition compared to the rower at the end of exercise.

Increases in pO 2 are generally indicative of impaired diffusive O 2 capacity from the circulatory system to active muscles, as observed in mitochondrial myopathic patients Taivassalo et al. Additionally, minute ventilation and oxygen pulse remained unchanged across conditions, thereby eliminating the possibility of a higher O 2 uptake at the pulmonary level.

While a direct relationship would conclude that higher O 2 availability in venous blood would be the by-product of lower O 2 extraction in the rower condition, V̇O 2peak was similar across conditions. However, without blood flow or arterial blood gases we cannot conclusively state that lower O 2 extraction was at play in the present results.

treadmill in normal exercise routines may have impacted our results, as familiarity and technique with the elliptical and rowing ergometer varied between participants.

Even though proper technical instructions and a familiarization session were provided, we cannot ignore possible influence of technique and lower mechanical efficiency, especially during rowing, on substrate oxidation.

Therefore, these results may not be generalizable to individuals who use an elliptical or rowing ergometer frequently. Additionally, blood samples were only obtained from the antecubital vein for all three exercise modalities.

Blood samples for the rowing and elliptical exercises may have been influenced by the metabolic activity of the arm due to greater upper extremity muscle activation during these exercises. Moreover, the sample used in the present study was composed of young and healthy individuals. Whether clinical or pathological populations would present similar metabolic responses to a variety of exercise modalities remains unknown.

While treadmill, elliptical and rower exercise modalities yield similar V̇O 2peak values, the research findings of the present study demonstrated that treadmill exercise elicited higher MFO, Fat max , and absolute rates of fat oxidation compared to elliptical and rower exercise, and that substrate oxidation curves were clearly influenced by exercise modality.

The treadmill remains the most efficient modality to increase fat oxidation during exercise and should be considered in training design for those looking to maintain a healthy metabolic profile.

Thank you to all who participated in this study. We also want to thank Robert Jack and Francis Theriault for their technical assistance, and Dr.

Endurance training induces a multitude of adaptations that result in increased fat oxidation. The duration and intensity of exercise training required to induce changes in fat oxidation is currently unknown. Ingestion of carbohydrate in the hours before or on commencement of exercise reduces the rate of fat oxidation significantly compared with fasted conditions, whereas fasting longer than 6 h optimizes fat oxidation.

Fat oxidation rates have been shown to decrease after ingestion of high-fat diets, partly as a result of decreased glycogen stores and partly because of adaptations at the muscle level. Each speed had been maintained for 3 min to measure the relationship between the energy consumption and heart rate of the participants during low-intensity activities.

After the indirect calorimetry assessments, the participants were asked to wear the heart rate monitor for 24 h to estimate their heart rates by daily activities performed in ordinary. The regression of heart rate and energy consumption calculated in the indirect calorimetry assessments had been used to calculate the total energy consumption of the participants.

Food energy were adjusted to meet the h total calories of each participant. The method recorded the energy consumption and the brand of heart rate monitors Polar in this study had been described elsewhere 10 , 18 , The experiment was conducted on a 6-day period.

On the first day, the participants arrived at the laboratory at and were instructed to rest quietly for 20 min in the supine position.

At the same time, gas analyzers were used to record their energy consumption. Subsequently, the participants were randomly allocated to the TRF or the CON trial.

The meals of the TRF trial were provided at , , and The participants in the TRF trial were required to consume all the food in the laboratory.

On the other hand, the similar meals of the CON trial were provided at , , and The participants in the CON trial were only required to consume the breakfast in the laboratory at but the other meals were not limited.

Except the breakfast, we reminded them to finish the meal on time by telephone. In addition to regular meals, a snack with approximately cal was provided as well. The participants in the TRF were only allowed to consume the snack from to , whereas no restrictions were imposed on the CON.

The meals were provided by the investigator three times a day throughout the 6-day period and designed by the professional dieticians. The calories of each meal met the daily energy requirement of each participant, which based on the results from the pretest.

The participants were instructed to maintain their habitual sleep and refrained from caffeine and exercise. The macronutrient consumption for TRF and CON were listed in Table 1.

After experiment completion on the fifth day, the participants returned to the laboratory on the sixth day from to They rested for 10 min in the supine position, and gas analyzers were used to collect the gas data of the participants for 20 min.

The average data from 5 to 15 min were used to assessed the fasting fat and carbohydrate oxidation data to avoid any error when move the equipment. Next, a catheter was inserted into the forearm of each participant to collect fasting blood samples. After blood sample collection, the participants were provided with a specific high-fat meal.

The participants rested quietly in the laboratory for 4 h, and their blood lipid changes during this period were observed. All oral fat tolerance test OFTT meals were designed and provided by dieticians, as previously described 10 , 20 , The meals included toast, butter, cheese, muesli, and cream.

For every kg of the body weight of the participant, the meal provided 1. The nutritional information was obtained from the nutritional facts on food packages. During the experiment, the participants were required to consume the OFTT meal within 15 min.

The average caloric and fat intake of the OFTT were In the experiment, a catheter Venflon 20G, Sweden was inserted into the vein of the forearm, and a three-way stopcock Connecta Ltd.

Blood was collected before meals, 30 min after meals, and every hour after meals up to the fourth hour. After each session of blood collection, 10 mL of isotonic saline water was used to clean the catheter to avoid blood clotting in the catheter. The collected blood was immediately placed in blood collection tubes containing ethylenediaminetetraacetic acid.

A cell counter was used to analyze the hematocrit Sysmax KXN, Kobe, Japan. After the analysis, the blood was centrifuged for 20 min at × g at 4 °C. The plasma were analyzed by using an automated biochemical analyzer , Hitachi, Japan with commercial reagents of TG Wako, Osaka, Japan , glucose GOD-PAP, Randox, Ireland , free fatty acid Wako, Neuss, Germany and glycerol Randox, Antrim, Ireland.

The insulin concentration in blood plasma was analyzed using a chemiluminescence immunoassay analyzer Elecsys , Roche Diagnostics, Basel, Switzerland and commercial reagents Roche Diagnostics, Basel, Switzerland.

The intra-assay coefficients of variation of the plasma measurement were TG: 4. The fat and carbohydrate oxidation rates were calculated using the following formula 22 :. The area under the curve AUC of plasma parameters and substrate oxidation rates were calculated using the trapezoidal rule 23 with excel Microsoft, Washington, USA.

The normality of the data was tested using the Shapiro—Wilk test. The fasting fat oxidation rate, blood biochemical values, and areas under the fat oxidation rate curve and the TG curve were analyzed using the paired sample t test.

The postprandial fat oxidation rate and blood biochemical values were analyzed using two-way ANOVA with repeated measures. If the data were significant, the Bonferroni method was used to perform post hoc comparisons. All other analyses were calculated by SPSS statistical software SPSS version 20, Chicago, USA.

The effect size Cohen's dz was 1. The postprandial fat oxidation over the 4 h A and the fat oxidation rate area under the curve in 4 h B. The postprandial triglycerides concentrations over the 4 h A and the TG area under the curve in 4 h B.

The postprandial glucose concentrations over the 4 h A , insulin concentrations over the 4 h B , glycerol concentrations over the 4 h C and non-esterified fatty acids concentrations over the 4 h. In this study, meals were provided that met the h energy requirement of each participant for 5 days.

The intervention was time-restricted feeding conducted at different parts of the day. The results revealed that time-restricted feeding effectively increased the fasting fat oxidation rate and the fat oxidation rate after the consumption of high-fat meals. However, the increased fat oxidation rate exerted no effects on the TG level following high-fat meals, h energy consumption, resting energy expenditure, or reactions of blood biochemical substances.

This study confirmed the fasting fat oxidation rate and the fat oxidation rate after the consumption of high-fat meals were effectively increased via the 5-day of time-restricted feeding period.

On the contrary, the h energy expenditure and resting energy expenditure showed no influence by the restricted feeding. Studies applying time-restricted feeding have mostly used interventions with a duration of a few weeks, and the results showed that time-restricted feeding decreased body weight and improved metabolism 7 , 8.

Studies that utilized short-term time-restricted feeding have discovered that 4 days of early time-restricted feeding consuming dinner before effectively increased the fat oxidation rate and reduced appetite, however, it did not affect h energy expenditure and resting energy expenditure 5.

A similar study demonstrated that 4 days of early time-restricted feeding improved the h blood glucose balance 6. In contrast to the aforementioned studies, this study used late time-restricted feeding consuming dinner before In addition, all the meals were prepared by the research team and were directly provided to the participants; hence, in this study, the diet of the participants could be more precisely controlled, instead of the participants consuming their own food.

This study discovered that late time-restricted feeding produced results similar to those achieved by early time-restricted feeding. In addition, compared with the control trial, time-restricted feeding did not affect the h energy metabolism of the time-restricted feeding trial, and time-restricted feeding effectively increased the fasting fat oxidation rate and the fat oxidation rate after the consumption of high-fat meals.

However, the glycerol and free fatty acid concentrations of the two trials were not different. Therefore, the exact mechanism through which time-restricted feeding increased the fat oxidation rate was unknown. In this study, time-restricted feeding could effectively increase the fasting fat oxidation rate and the postprandial fat oxidation rate, but it did not affect the TG level after the consumption of high-fat meals.

This result indicated that 5 days of short-term time-restricted feeding resulted in a shorter action time for the higher fat oxidation rate, which may not effect on the postprandial TG level. The possible mechanisms may be due to the increased of adrenergic activity 25 or the thermic effect of food 5.

Chiu et al. used three high-fat meals per day to change the fat oxidation rate of participants; although this method effectively increased the fat oxidation rate, it did not affect the TG level after the consumption of high-fat meals This study demonstrated that the fat oxidation rate of the time-restricted feeding trial was significantly higher than that of the control trial; however, glycerol and free fatty acid concentrations were not significantly different.

Therefore, although short-term time-restricted feeding effectively increased the fat oxidation rate, it did not affect the postprandial TG reaction. Another possible reason for the intervention not affecting the TG level after the consumption of high-fat meals is that 5-day time-restricted feeding did not affect blood glucose and insulin concentrations.

Studies have suggested that insulin sensitivity is a major factor that affects the TG level after the consumption of high-fat meals Compared with late time-restricted feeding, early time-restricted feeding reduced postprandial blood glucose concentration to a higher extent in a previous study However, that study did not limit the calorie intake, and participants were 55 years old and were at a high risk of diabetes.

In comparison, this study provided all the meals to the participants during the experiment to ensure that the calorie intake of all the participants was equal. In addition, this study controlled the calorie intake to ensure that it met the h energy requirement of the participants, and the results revealed that fasting and postprandial blood glucose concentrations and the insulin concentration were unaffected.

Accordingly, the insulin sensitivity of the participants remained unchanged; thus, the postprandial TG level was unaffected. The male subjects recruited in this study belonged to healthy population, which had the low fasting TG levels. However, it is not certain in the results would apply to overweight, middleaged and older adults, or in at-risk populations.

The fasting fat oxidation rate were 0. Therefore, the 5 days of time-restricted feeding not only increased the fat oxidation rate in healthy normal weight male subjects as overweight subjects 5 , but also maximized the fat oxidation rate.

This may be an explanation that why the fat oxidation cannot be further increased after consuming a high fat meal. Nonetheless, this present study indicated that time-restricted feeding increased the fasting and postprandial fat oxidation, which likely lead to improved fat metabolism or cardiometabolic health Moreover, the further research is required to investigate the effect of TRF on postprandial response after a high fat meal in the overweight or at-risk populations.

The main of this study was the calculation of h energy consumption. The h energy consumption was determined through calculation, rather than through measurement by methods such as those using the respiratory chamber. Calculations would not be as accurate as actual measurements. Studies have tested h energy consumption and yielded robust results using methods similar to that used in the present study 10 , 18 , Therefore, we believe that this method is still credible.

The other limitation was that we only measure the 4th hour postprandial outcomes. Further study may be needed to investigate the postprandial outcomes for a longer time. This study discovered that consuming meals with the same amount of calories for 5 days and using time-restricted feeding as the intervention can effectively increase the fasting fat oxidation rate and the fat oxidation rate after the consumption of high-fat meals.

However, the increased fat oxidation rate did not increase the TG level after the consumption of high-fat meals in the healthy male participants. The further research is required to investigate the effect of time-restricted feeding on postprandial response after a high fat meal in the overweight or at-risk populations.

How to Lose Fat with Science-Based Tools

Fat oxidation benefits -

Simple sugars create larger insulin spikes in the body than complex carbohydrates or protein. As we stated above, increasing your calories out is one of the ways you can tip energy balance in favor of fat loss.

This, of course, is accomplished through exercise, and we can maximize fat burning by performing the right types of exercise. Science has pretty clearly shown that during exercise, your muscles can use both dietary carbohydrate and fat operate as substrates used for energy. Your body has a finite amount of glycogen stored in the muscle.

Once these stores are exhausted, the body will start pulling from your fat stores for energy. Low to moderate intensity forms of exercise primarily use fat as their source of energy. The higher you go with exercise intensity, the more you shift to burning glycogen and glucose.

The longer you train, the more you deplete glycogen and once those stores are depleted, you will switch to burning fat for fuel. Additionally, the more fit you are, the lower your resting insulin levels will be, thus allowing you to burn more fat outside of your eating windows.

Due to these factors, you can begin to understand why most fasted cardio sessions are performed at a relatively low intensity -- it maximizes fat burning in the body. The oxygen deficit created by high-intensity forms of training such as weight lifting or interval training leads to greater overall calorie burning as your body works to restore homeostasis.

The point of this is to say that both steady-state and high-intensity interval training can be used to lose body fat. The mechanisms by which they work are different, but the end result is the same. Fat burning is a billion-dollar industry, yet very few people actually understand the theory and science of what it takes to burn fat, and even fewer know how to apply it to daily life.

And, if you need some help burning extra calories and shifting your body towards a greater fat burning environment, check out Steel Sweat. Steel Sweat is the ideal pre-workout for fasted training. Not only does it include ingredients such as caffeine which help release fatty acids to be burned for energy it also includes several pro-fat burning compounds, such as L-Carnitine L-Tartrate and Paradoxine, which take those liberated fatty acids and burn them for energy.

Clear Close. Ingredients The Complete Guide to Fat Oxidation. Educate them. Fat Burning vs. What does fat oxidation mean? What Happens during Fat Oxidation?

Oxidation: Burning Fat for Fuel As the fatty acids enter the cell, they are stored in the cytoplasm of the cell, which is the thick solution that fills the inner regions of the cell. How to Increase Fat Oxidation Since most people entering the fitness space are wanting to lose fat, it would make sense to discuss what things we can do to enhance fat oxidation and accelerate fat loss.

Reduce Calories One of these ways is by reducing caloric expenditure, i. Regulate Insulin Levels Earlier in this article, we discussed the importance of hormone-sensitive lipase in the liberating of stored fatty acids from adipose tissue.

Is there anything you can do? Indeed, it was previously observed that the lipolysis rate at rest is increased in women with upper body obesity compared with those with lower body obesity Jensen et al. Therefore, it could be hypothesized that the exercise intensity threshold to promote lipolysis and fat oxidation is different for women with upper and lower body obesity.

To our knowledge, no information is available on the impact of exercise training on substrate oxidation in relation with fat mass localization in women with normal weight. Interestingly, Van Aggel-Leijssen and colleagues found that the relative fat oxidation during exercise increased only in women with upper obesity, and they did not observe any change in body weight and composition in both groups women with upper and lower obesity after the 12 weeks of endurance training.

These results question the influence on body composition of the increased fat oxidation in response to endurance training in this population. Indeed, endurance exercise increases the capacity to use fat at rest and during exercise, suggesting an effect on body weight and fat mass loss via greater fat oxidation Jeukendrup, However, higher fat oxidation during exercise and changes in body composition in response to exercise training are not necessarily associated.

Indeed, due to the effect of carbohydrate ingestion on fat metabolism, the pre-exercise nutritional status fasting vs. post-prandial and eating habits quality and quantity must be considered when studying body weight and fat mass loss Melanson et al.

In addition, the magnitude of fat oxidation during exercise may not be sufficient to induce fat mass loss. Nevertheless, even if increased fat oxidation may not be associated with a decrease in fat mass in response to endurance training, the exercise-mediated improvement in fat oxidation is important not only for body composition and weight management, but also for cardio-metabolic health.

Indeed, the capacity to oxidize fat during exercise is inversely related to cardio-metabolic comorbidities e.

Therefore, it is essential to promote additional studies on this topic considering both components of fat balance. It is recognized that aging is associated with increased fat mass accumulation and menopause leads to a shift toward upper body fat mass deposition.

However, and surprisingly, little is known about the effect of fat mass localization on substrate oxidation during endurance exercise in post-menopausal women. Some studies investigated the influence of menopause and the related body composition modifications on substrate metabolism at rest and during exercise Lovejoy et al.

It has been reported that in women with normal weight, whole-body lipolysis is not affected by menopause in post-absorptive and also in hyperinsulinemic conditions Toth et al. Lipolysis is higher in abdominal than in peripheral adipocytes in post-menopausal women with upper and also lower body obesity Nicklas et al.

In addition, in post-menopausal women with obesity, higher VAT is associated with increased fat oxidation, independent of total body fat mass Nicklas et al. According to these results, obesity may override the effect of body shape on lipolysis, while fat oxidation depends on fat mass localization.

It is worth noting that many studies that investigated the effect of menopause on lipid metabolism were performed in women with obesity, mainly due to its increased prevalence within this population.

It would be relevant to know whether results are similar in women with normal weight and whether the obesity history onset before vs. after menopause leads to distinct lipid metabolism responses. As weight gain in menopause increases the risk of obesity and cardio-metabolic disorders, many women may want to lose weight.

Hypocaloric diets induce fat mass loss in the short term, but the rate of weight loss progressively decreases over time.

The metabolic adaptations occurring during prolonged diet restriction i. In post-menopausal women with obesity, endurance training counteracts this decline in weight loss Nicklas et al.

These results suggest the importance of regular exercise to minimize the potential adverse effects of menopause associated with obesity on lipid metabolism. Indeed, physical activity is a key component of menopause management Kanaley et al. Lange and colleagues reported that lipolysis in subcutaneous abdominal adipose tissue during endurance exercise is not altered in post-menopausal women Lange et al.

Interestingly, it has been observed that fat oxidation during exercise is reduced in post-menopausal compared with premenopausal women. This difference was mainly explained by the reduced lean body mass, suggesting, once more, the importance of regular exercise to manage body composition Abildgaard et al.

In addition, the lower ability to oxidize fat was related to the worsened metabolic profile and increased VAT, thus highlighting the influence of fat mass localization on substrate oxidation during exercise in post-menopausal women.

This suggests the importance of upper adipose tissue quality for substrate metabolism. The authors noted that sexual dimorphism in substrate oxidation during exercise was unlikely to be explained by plasma estrogen concentrations, which were comparable between groups.

They hypothesized that intramyocellular triglyceride content and muscle morphology may play a role Numao et al. Overall, more randomized clinical trials are needed to investigate the effect of fat mass localization on fat oxidation during acute and chronic endurance exercise in women with normal weight and obesity, before and after menopause.

In addition, due to the lack of experimental studies, the present review only focused on fat oxidation during endurance exercise and it is not known whether these findings might also apply to other exercise modalities e. Over the years, many studies have described, mainly at rest, the deleterious effects of upper body adiposity and its association with the risk of cardio-metabolic alterations.

Although it is acknowledged that regular physical activity plays a pivotal role in fat metabolism regulation, and thus in body composition management and cardio-metabolic health, data on the impact of fat mass localization on substrate utilization during exercise in women are scarce.

Interestingly, although few studies are available on this topic, the weight status appears to be a confounder in the relationship between fat mass localization and fat oxidation during acute endurance exercise in premenopausal women Figure 1.

Higher abdominal fat depot is associated with impaired submaximal and maximal fat oxidation and metabolic inflexibility during exercise in women with normal weight.

Conversely, no difference is observed in women with upper and lower body obesity. Understanding these disparities is essential to provide optimized prevention and treatment strategies for cardio-metabolic comorbidities. LI and NB had the idea for the review article.

LI and GE performed the literature search and data analysis and drafted the review article. NB critically revised it. All authors contributed to the article and approved the submitted version. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Are there easy ways to increase fat burning? Are there easy ways to become lean? In a series of articles on mysportscience. com I want to evaluate the following:. What is fat burning? And how is it regulated in the body? What is the evidence for each of these reasons? If we want to burn fat, what are the best methods to do this?

Can we come up with some general advice? Fat burning or fat oxidation the term preferred by scientists occurs on a daily basis in virtually all cells of our body. Fat is stored in the form of triglycerides. A triglyceride is made up of 3 fatty acids that are held together by a glycerol backbone hence the name tri-glyceride.

Only fatty acids can be used as a fuel. Therefore triglycerides first need to be broken down into fatty acids. The fatty acids then need to be broken down further. Fat oxidation refers to the process of breaking down fatty acids. To oxidize fat one needs:. Healthy mitochondria small structures in cells that serve as the power plants of the cells.

In these power plants, energy is generated for muscle contraction by burning fuel, using oxygen and producing carbon dioxide. Supply of fatty acids these are supplied from triglycerides and fatty acids in the blood, as well as triglycerides stored in the muscle itself.

Oxygen transported to the muscle by blood. If fatty acids are supplied to healthy mitochondria and oxygen is present, fatty acids will be broken down to carbon dioxide.

This process is not too dissimilar form burning a log in a fire. You need the fireplace, some wood and oxygen. As mentioned above, the fatty acids we burn can come from different sources. Fat is stored as triglycerides in different tissues of the body, including muscle. The vast majority of triglycerides in our bodies can be found in fat cells.

When we eat, fat will eventually appear in the blood stream and can potentially be taken up and used in the muscle. When we exercise, our need for energy increases dramatically because muscle contraction is an energy consuming process.

Some of this energy will come from fat burning. The availability of fat in the muscle.

Faat acids are an Fat oxidation benefits energy source during exercise. Training status and substrate availability are determinants Faat the relative Fat oxidation benefits absolute contribution of bensfits acids and glucose to total energy Fat oxidation benefits. Endurance-trained athletes have a high Inflammation and joint pain capacity, while, in insulin-resistant individuals, fat oxidation is compromised. Fatty acids that are oxidised during exercise originate from the circulation white adipose tissue lipolysisas well as from lipolysis of intramyocellular lipid droplets. Moreover, hepatic fat may contribute to fat oxidation during exercise. Nowadays, it is clear that myocellular lipid droplets are dynamic organelles and that number, size, subcellular distribution, lipid droplet coat proteins and mitochondrial tethering of lipid droplets are determinants of fat oxidation during exercise.

Moreover, endurance exercise is an effective strategy for improving fat oxidation, suggesting that regular endurance exercise could contribute to the management of body composition and metabolic health. However, no firm conclusion has been reached on the effect of fat mass localization on fat oxidation during endurance exercise. By analyzing the available literature, this review wants to determine the effect of fat mass localization on fat oxidation rate during endurance exercise in women, and to identify future research directions to advance our knowledge on this topic. Despite a relatively limited level of evidence, the analyzed studies indicate that fat oxidation during endurance exercise is higher in women with lower upper-to-lower-body fat mass ratio than in women with higher upper-to-lower-body fat mass ratio.

All the participants had not undergone physical training; they did not exercise regularly; and they did not have any diseases that would prevent them from performing exercises, such as high blood pressure, hyperlipidemia, heart disease, joint disease, and osteoporosis.

All the participants fully understood the experimental process before experiment initiation and were notified of the possible risks; they agreed to the terms of the experiment and provided their written consent. All the participants fully understood the experimental process before experiment initiation and were notified of the possible risks; they agreed to the terms of the experiment and provided their written informed consent.

The participants also be informed of avoid trying to lose weight or change the dietary habit during the study.

A similar number of participants and a similar recruitment method have been employed by this research team in the past. This study was approved by the Institutional Review Board of Jen-Ai Hospital in Taiwan and registered in the ClinicalTrials.

This study follows the principles of the Declaration of Helsinki and follows the recommendations proposed by the CONSORT Statement. This study used a crossover design for the experiment. The participants were divided into the time-restricted feeding trial abbreviated as TRF and the control trial abbreviated as CON.

All participants consumed the same meals for 5 days. They also be informed of avoid trying to lose weight or change the dietary habit during the study. The TRF trial used the methods to practice intermittent fasting The meals were provided at, and The meals of the CON trial were provided at, andbut the consumption time was not limited.

On the morning of the sixth day, all participants returned to the laboratory to consume a high-fat meal, and were investigated the TG blood levels after the meal.

The participants were randomly assigned to different arms of the study to receive different treatments, and an interval of at least 14 days was maintained between the tests to avoid any effects of the preceding test on the succeeding test.

Studies have reported that 4 days of intermittent fasting effectively increased the fat oxidation rate and reduced blood glucose 56.

Therefore, 5 days of time-restricted feeding should provide sufficient intervention time to stimulate fat oxidation rate changes. The primary outcome measure was fat oxidation rate and the blood biochemical analysis was the second.

The pretest was to assess the total daily energy expenditure by indirect calorimetry through a series of resting assessments and exercising assessments. In addition, the gas analyzers Vmax Series 29C, Sensor Medics, CA, USA were used to assess the energy consumption of the participants while they were resting and performing nonmaximal intensity exercises for precisely calculating the daily calorie consumption of each participant.

In the laboratory, each participant underwent heart rate monitoring with a heart rate monitor Polar, Finland. And the energy consumption was examined by using the gas analyzers.

The participants were instructed to rest quietly for 20 min in the supine position for recording their resting heart rate and energy consumption. After resting, they were required to perform nonmaximal intensity exercises for measuring their energy consumption during low-intensity activities.

First, the energy consumption during standing was recorded by standing on a treadmill with a slope of 0° for 10 min. Second, the participants were instructed to walk or run at five respectively speeds, which were set as 1, 2, 3, 4, and 5 miles per hour.

Each speed had been maintained for 3 min to measure the relationship between the energy consumption and heart rate of the participants during low-intensity activities.

After the indirect calorimetry assessments, the participants were asked to wear the heart rate monitor for 24 h to estimate their heart rates by daily activities performed in ordinary.

The regression of heart rate and energy consumption calculated in the indirect calorimetry assessments had been used to calculate the total energy consumption of the participants.

Food energy were adjusted to meet the h total calories of each participant. The method recorded the energy consumption and the brand of heart rate monitors Polar in this study had been described elsewhere 1018 The experiment was conducted on a 6-day period.

On the first day, the participants arrived at the laboratory at and were instructed to rest quietly for 20 min in the supine position. At the same time, gas analyzers were used to record their energy consumption. Subsequently, the participants were randomly allocated to the TRF or the CON trial.

The meals of the TRF trial were provided at, and The participants in the TRF trial were required to consume all the food in the laboratory. On the other hand, the similar meals of the CON trial were provided at, and The participants in the CON trial were only required to consume the breakfast in the laboratory at but the other meals were not limited.

Except the breakfast, we reminded them to finish the meal on time by telephone. In addition to regular meals, a snack with approximately cal was provided as well. The participants in the TRF were only allowed to consume the snack from towhereas no restrictions were imposed on the CON.

The meals were provided by the investigator three times a day throughout the 6-day period and designed by the professional dieticians. The calories of each meal met the daily energy requirement of each participant, which based on the results from the pretest.

The participants were instructed to maintain their habitual sleep and refrained from caffeine and exercise. The macronutrient consumption for TRF and CON were listed in Table 1. After experiment completion on the fifth day, the participants returned to the laboratory on the sixth day from to They rested for 10 min in the supine position, and gas analyzers were used to collect the gas data of the participants for 20 min.

The average data from 5 to 15 min were used to assessed the fasting fat and carbohydrate oxidation data to avoid any error when move the equipment. Next, a catheter was inserted into the forearm of each participant to collect fasting blood samples. After blood sample collection, the participants were provided with a specific high-fat meal.

The participants rested quietly in the laboratory for 4 h, and their blood lipid changes during this period were observed.

All oral fat tolerance test OFTT meals were designed and provided by dieticians, as previously described 1020 The meals included toast, butter, cheese, muesli, and cream.

For every kg of the body weight of the participant, the meal provided 1. The nutritional information was obtained from the nutritional facts on food packages. During the experiment, the participants were required to consume the OFTT meal within 15 min. The average caloric and fat intake of the OFTT were In the experiment, a catheter Venflon 20G, Sweden was inserted into the vein of the forearm, and a three-way stopcock Connecta Ltd.

Blood was collected before meals, 30 min after meals, and every hour after meals up to the fourth hour. After each session of blood collection, 10 mL of isotonic saline water was used to clean the catheter to avoid blood clotting in the catheter. The collected blood was immediately placed in blood collection tubes containing ethylenediaminetetraacetic acid.

A cell counter was used to analyze the hematocrit Sysmax KXN, Kobe, Japan. After the analysis, the blood was centrifuged for 20 min at × g at 4 °C. The plasma were analyzed by using an automated biochemical analyzerHitachi, Japan with commercial reagents of TG Wako, Osaka, Japanglucose GOD-PAP, Randox, Irelandfree fatty acid Wako, Neuss, Germany and glycerol Randox, Antrim, Ireland.

The insulin concentration in blood plasma was analyzed using a chemiluminescence immunoassay analyzer ElecsysRoche Diagnostics, Basel, Switzerland and commercial reagents Roche Diagnostics, Basel, Switzerland.

The intra-assay coefficients of variation of the plasma measurement were TG: 4.
