Muscle preservation and bone density -
People with vitamin D deficiencies have a higher risk of losing bone mass. A person can absorb vitamin D through moderate sun exposure. Without sufficient vitamin D, a person has a higher risk of developing bone disease, such as osteoporosis or osteopenia. A moderate weight is essential for bone density.
People with underweight have a higher risk of developing bone disease. Overweight and obesity put additional stress on the bones.
Doctors recommend people avoid rapid weight loss and cycling between gaining and losing weight. As a person loses weight, they can lose bone density, but gaining back the weight will not restore bone density.
This reduction in density can lead to weaker bones. Super low calorie diets can lead to health problems, including bone density loss. Before restricting calories, discuss calorie needs with a qualified healthcare professional, such as a primary care doctor or registered dietitian, to determine a safe target number of calories to consume.
Protein plays an essential role in bone health and density. A cross-sectional study examined bone mass and dietary protein intake in 1, older adults. Researchers associated higher bone mass density with higher intakes of total and animal protein.
However, they associated lower bone mass density with plant protein intake. Researchers call for further studies, particularly into how a plant-based diet may affect bone health and density. Research suggests that omega-3 fatty acids play a role in maintaining bone density and overall bone health.
Like calcium, magnesium and zinc are minerals that support bone health and density. Magnesium helps activate vitamin D so it can promote calcium absorption. Zinc exists in the bones. It promotes bone growth and helps prevent the bones from breaking down. Many people associate smoking with lung cancer and breathing issues, but smoking can also increase the risk of conditions such as osteoporosis and bone fractures.
To support healthy bone density, a person can avoid or quit smoking , especially during their teens and young adulthood. However, long-term heavy drinking can lead to poor calcium absorption, a decrease in bone density, and the development of osteoporosis later in life.
Moderate alcohol consumption is considered two drinks or fewer per day for males and one drink or fewer per day for females. Although the best time to influence peak bone mass and build bone density is from childhood to early adulthood, people can take steps at every age to improve bone health and reduce bone density loss.
Strength training exercises can increase bone density in specific parts of the body in the short and medium term. However, people need to continue exercising regularly to maintain bone health in the long term. Bone mass peaks in young adults, usually between 25 and 30 years old. After 40 years old, people start to lose bone mass.
However, they can reduce this loss by exercising regularly and eating a balanced, nutrient-dense diet. Dietary intake of calcium and vitamin D is vital for bone health.
Foods that contain these nutrients include:. To support healthy bone density, it is important to consume plenty of calcium, vitamin D, protein, and vegetables. It is also important to avoid smoking and heavy alcohol use.
Taking these steps can help support bone density throughout adulthood. Read this article in Spanish. A Z-score compares a person's bone density with the average bone density of those of the same age, sex, and body size.

Therefore, the aim of the present study was to assess the efficacy of a short high-intensity jump training as a countermeasure for the deconditioning effects of physical inactivity. We hypothesized that there would be significant differences between training and control group after bed rest with respect to bone mineral content and density of the tibia, leg lean mass, maximal strength of the leg extensors, and peak oxygen uptake capacity.
For this randomized controlled study, 23 male participants were subjected to 60 days of strict bed rest. In addition, two weeks before and after the bed rest phase, participants were confined to the bed rest facility for familiarization, measurements and recovery, see Fig.
Subjects were randomly allocated to the jump training group JUMP, 12 participants or the control group CTRL, 11 participants. Participants in the training group trained x per week see Fig. Study overview. Prior to the bed rest phase, participants spent 14 days in the bed rest facility for familiarisation and baseline data collection BDC through BDC In the morning of the first head-down tilt bed rest day HDT1 , participants were randomly assigned to either the training group JUMP, total of 48 training sessions during the 60 days of bed rest or the control group CTRL.
The training device sledge jump system, SJS. The participant is fixed to the wooden sledge with shoulder straps, and his thighs rest on additional straps.
The straps are attached to the rails and can slide in the direction of the rails with minimal friction. The participant is pulled towards the force plates by the force generated by the low-pressure cylinders. Leg lean mass based on DXA analyses, normalized to BDC-3 values. Isometric maximal voluntary contraction MVC torque was recorded during knee extension, knee flexion, plantar flexion and dorsiflexion.
In addition to the MVC tests for the lower extremity, maximal handgrip strength was recorded as a control measure of upper extremity strength.
This was tested during sustained submaximal isometric contractions of the knee extensors. Oxygen uptake and carbon dioxide emission as well as heart rate were recorded, and peak oxygen uptake was determined as a measure of aerobic capacity. The short but intensive jump training program was successful in preserving bone mass, maximal muscle force and peak oxygen uptake capacity throughout the 60 days of strict physical inactivity during bed rest.
It is remarkable that bone mineral content and density of the tibia could be maintained at all measured sites by the jump training during bed rest, while the various countermeasures used in previous bed rest studies were sometimes not even able to attenuate bone loss.
Non-exercise countermeasures such as nutrition or pharmacological interventions were in general least successful in maintaining bone mass.
Similarly, doubling calcium intake did not have a significant effect on bone turnover markers during short-term bed rest Results from bed rest studies using some form of exercise as a countermeasure were in general more promising, but most training interventions were still hardly able to maintain bone mass: the combination of aerobic exercise treadmill and resistance exercise flywheel used in the WISE study showed no significant effect compared to control The whole body vibration training partly combined with resistance exercise that was used in the two Berlin Bed Rest BBR studies was quite effective 20 , although there were still some BMC reductions at some of the measured sites, notably the tibia This comparison supports the mechanostat model, which states that mechanical loading of the bones is necessary and that this mechanical loading has to be high enough to cause bone deformation in a certain strain range In-vivo studies have shown that the strains necessary to preserve tibial bone mass according to the mechanostat model are generated during high-impact exercise such as running or jumping, whereas low-impact exercises such as cycling or even high-effort exercises such as leg press do not produce strains that are consistently above the threshold 12 , As expected, the pQCT measurements of the radius did not show any significant differences between groups and no main effect of time, in line with previous bed rest studies measuring the radius as an upper body control Even though the training consisted of highly dynamic movements, the isometric MVC tests showed no significant decrease for the training group in maximal knee extension torque and sustained knee extension torque, and only a small decrease in maximal plantar flexion torque.
The combination of flywheel and treadmill exercises used in the WISE study was more effective, but the decrease in isokinetic MVC could also not be completely prevented The finding that despite exercise, peak plantar flexion MVC decreases more after bed rest than knee extension MVC has been attributed to differences in habitual loading in daily life 26 , especially for the soleus muscle with its higher proportion of slower muscle fibres Consequently, a training program with a larger training volume is probably more suitable to maintain calf muscle strength, and a high-intensity training probably affects the gastrocnemius muscle more than the soleus muscle.
Nevertheless, it is remarkable that the jump training used in the present study was able to almost maintain peak plantar flexion torque despite the low training volume. Leg flexor strength was less affected compared to leg extensor strength. This is also the reason why most exercise countermeasures have focused on the leg extensors and consequently failed to protect the leg flexors It is therefore remarkable that even though the jump training used in the present study focused on the leg extensors, it was also successful in preventing the decrease in knee flexion strength observed in the control group.
One possible explanation for the efficacy of the jump countermeasure in that regard is that the leg flexors are also active during jumps: as the high forces during jumps have to be met by high joint stability to prevent injuries, co-activation of the antagonists for example the hamstrings for the knee joint has been proposed as one strategy to increase joint stabilization 29 , and it has been shown that jump training can increase hamstring peak torque and power Thus, the training maintained not only MVC, but also local muscle endurance in a submaximal task.
As hypothesized, handgrip strength as an upper body control value was not affected by the training and also did not change after bed rest in the inactive subjects, which is in line with previous findings The changes in leg lean tissue mass showed a similar pattern as the muscle strength tests, i.
This disproportionately higher decrease in muscle function compared to muscle mass loss has already been reported in previous unloading studies Possible explanations include alterations in neural drive and changes in muscle fibre properties, such as thin filament density 33 and force per cross-sectional area These changes in muscle microarchitecture are not detected when using macroscopic-level imaging methods such as DXA, which consequently underestimate the loss in muscle function.
Unfortunately, there seem to be no publications on the effects of the resistance training used in LTBR and the combined resistance and vibration training used during BBR1 and BBR2 on aerobic capacity. Non-exercise countermeasures such as amino acid supplementation do not seem to have any positive effect on VO2peak The reason for the efficacy of the jump training program on aerobic capacity is probably its high intensity: especially the training sessions with short breaks in between series can be seen as a form of high-intensity interval training, which has been shown to increase aerobic capacity to a similar extent as higher-volume continuous endurance training with moderate intensity It has to be noted though that in contrast to BMC, BMD and MVC, aerobic capacity was not equal between groups during the baseline measurements.
This result of the random subject allocation and the small sample size is a limitation of the study, but the large effect size of the interaction effect makes it unlikely that the baseline group differences had a fundamental influence on the results.
In summary, the low-volume, high-intensity jump training protocol used in the present study was very effective compared to potential countermeasures tested in previous long-term bed rest studies.
It was able to maintain structure and function of three different organ systems at once bone, muscle and cardiovascular system with only one exercise mode jumps , whereas other countermeasures were only effective in maintaining one or two of these three systems, even though they used a combination of exercise modes e.
Possible reasons for the success of the jump training program include the exposition to high peak forces and rates of force development during the training which are considered to be important for bone modelling , the high power output of the leg extensors in a whole-body movement with a large range of motion which was probably an important factor in maintaining muscle function also in untrained tasks , and the high-intensity interval nature of the training, which might be seen as a key factor in maintaining aerobic capacity.
All in all, the jump training proved to be a truly integrated effective and time-efficient countermeasure for the deteriorating effects of strict physical inactivity on tibial bone mineral content, bone mineral density, maximal leg muscle strength, local muscle endurance and leg lean mass as well as peak oxygen uptake capacity.
Consequently, we suggest to verify the feasibility of jump training in at-risk populations and then incorporate it as a very time-efficient and effective type of exercise into the training programs for the elderly, astronauts on long-term space missions, and sedentary populations, especially those with a high osteoporosis risk.
This randomized controlled single-centre, parallel-group study with balanced randomisation was conducted at the:envihab facility of the German Aerospace Centre DLR in Cologne.
The study was split into two campaigns with initially 12 participants each. The first campaign started in August , the second campaign in January During the adaptation and recovery phases BDC and R , physical activity was restricted to free movement within the ward.
During the entire study, the subjects received a strictly controlled diet. For details, see Of the 24 healthy male subjects that were enrolled in the study, one subject discontinued the study on BDC-4 for medical reasons unrelated to the study.
One participant started in the training group, but was reallocated to the control group after three training sessions due to a possible medial tibia stress syndrome. Two of the 23 subjects that completed the study one CTRL, one JUMP were re-ambulated after respectively 49 and 50 instead of 60 days of HDT due to medical reasons, but completed the recovery phase with all the scheduled measurements except for the spiroergometry.
Before taking part in the study, all participants gave written informed consent to all the experimental procedures, which were in accordance with the relevant guidelines and regulations, and were approved by the ethics committee of the Northern Rhine Medical Association Ärztekammer Nordrhein in Duesseldorf, Germany, as well as the Federal Office for Radiation Protection Bundesamt für Strahlenschutz.
Exclusion criteria were chronic hypertension, diabetes, obesity, arthritis, hyperlipidaemia, hepatic disease A, C , disorder of calcium or bone metabolism, or heritable blood clotting disorders. Volunteers that were medically eligible for the study subsequently underwent psychological screening, involving questionnaires and interviews.
The recruitment process was concluded by a dual energy X-ray absorptiometry DXA screening of the bone mineral density of the femur and the lumbar vertebra column. The sledge jump system SJS, see Fig. It consists of a frame on wheels and a lightweight sledge that is attached to the rails.
The participant is attached to the sledge via two straps around the shoulders, allowing movement in a natural manner 39 , The force that pulls the sledge towards the force plates is generated by low-pressure cylinders that are able to generate any force between zero and N by altering the pressure of the cylinders.
During nine sessions during BDC, all subjects were familiarized with the correct jumping technique in the SJS. The training protocol for the JUMP group during the 60 days of HDT comprised a total of 48 training sessions. Peak forces during the training amounted to 3.
Further details about the training can be found in The pQCT images were processed with the XCT software version 6. Knee extension and knee flexion torque were assessed in a sitting position with a hip angle of 90°, knee angle of 90° and ankle angle of 0°. Plantar flexion and dorsiflexion torque was assessed in a supine position with hip, knee and ankle angles of 0°.
MVC data analogue torque signals of the Isomed were corrected for possible offsets, followed by extraction of the maximal torque during each trial via a Matlab Mathworks Inc, Natick, USA script. The maximum of the six trials was used for further statistical analyses. In addition to the MVC tests for the lower extremities, maximal handgrip strength of the dominant hand was recorded as a measure of upper extremity strength.
For that purpose, a Jamar Plus Patterson Medical, Warrenville, USA hand dynamometer was used. During testing, subjects were seated with hips and knees at 90°, right arm in a vertical position elbow and wrist extended. Three trials of five seconds each were conducted and the highest of the three results used for further analyses.
Breath-by-breath oxygen uptake and carbon dioxide emission was monitored using the Innocor system Innovision, Odense, Dänemark , heart rate was continuously monitored via lead ECG Padsy, Medset Medizintechnik, Germany. Afterwards, the peak values for the following parameters were extracted: VO2, heart rate, respiratory exchange rate, and ergometer power.
If the peak respiratory exchange rate was below 1. The data that support the findings of this study are available from the authors upon reasonable request and with permission of the European Space Agency ESA. The study was registered with the German Clinical Trial Registry DRKS, registration number DRKS, 18 th of September Sample size estimations were based on the results of previous bed rest studies, with an additional margin for potential dropouts power of 0.
Participants were aware of their group allocation, and no strict measures were taken to blind outcome assessors and data analysts, even though most of them were unaware of group allocation.

Bone density changes over time. Throughout childhood, adolescence, and early adulthood, the bones absorb nutrients and minerals, gaining strength. However, as a person enters their late 20s, they reach their peak bone mass, meaning they will no longer gain bone density.

The reason we Herbal slimming supplements bone and muscle as we age densify attributed to a combination of lower physical activity levels, hormonal decline, an increase in aged senescent cells, and a lifetime accumulation of micro damage due to oxidative stress that escaped repair.
All of these factors serve to impact the hormonal and metabolic health of the bones and muscles. Bone Morphogenic Protein as an Indicator of Bone and Muscle Aging.
One prime example pertains to age-related elevations of bone morphogenic protein BMP. When BMP levels are moderate, it helps to stimulate optimal bone mineral balance and muscle growth. When too high or low, BMP can cause the opposite problem, promoting bone resorption [7]mineral density loss, suppressed regeneration, and muscle atrophy [8].
These are commonly seen in aged individuals with osteoporosissarcopenia, and osteoarthritis. In turn, muscle atrophy contributes towards weakening the bones due to a lower expression of signals that would keep bone density in balance.
Activity as the Most Potent Musculoskeletal Hormone Stabilizer. Exercise has been shown to regulate BMP levels, simultaneously increasing the growth of bone and muscle, as well as promoting tissue regeneration and reductions in senescent cells. Muscle building can be done at any age, yet the benefits for bone are a lot more pronounced in those who have been consistently doing so from a younger age.
This is due to age-related changes in muscle loss and maintenance, as described briefly below. At What Age Do We Lose Muscle? Muscle mass begins to decline gradually from the third decade of life, and muscle strength begins to decline after reaching This decline can occur more rapidly for women than for men after women reach menopause.
These are merely average statistics, and it is important to understand that the process can be sped up or slowed down. Common Age-Related Muscle Deficits. Age-related muscle loss is known as sarcopenia, which frequently occurs in connection to bone density loss.
Common symptoms of sarcopenia include reduced motor coordination, visual acuity loss, and a decreased ability to balance.
Senior individuals who were physically active for most of their lives are usually still capable of building muscle. The body contributes towards counteracting age-related muscle impairments in the elderly.
Muscle loss is more pronounced in the lower extremities, which is often the result of being less physically active. Where and When to Actively Focus. Given these observations, starting to exercise at a younger age is important for still being able to exercise optimally during old age.
Older individuals can focus on building muscle in the lower extremities and in vulnerable areas, such as the hip and spine. Balance and coordination are also important for keeping up the ability to move without risking falls and fractures. For those looking to work out in order to add some more physically active years to their lives later on, the suggestions below may be useful.
Full-Body Workouts Lead to Optimal Skeletal Preservation. As exercising a muscle improves its size and strength and the bone that supports it, it is important to engage in full-body workouts and to focus on areas that are more vulnerable to deterioration.
While building select muscles may have value for overall body muscle strength as revealed in hand grip strength testingthe same does not apply to the bone, which is far more selective and typically responds to local input.
This is supported by several studies. During aging, the hips and spine are known to deteriorate more than other body areas and are common causes of age-related aches, pains and injuries. These are important areas of focus for building bone and muscle, as are the legs and arms.
It has been shown that the upper extremities can help to compensate for very old individuals later on who have difficulty moving, yet this phase of aging can easily be delayed by keeping the lower extremities fit as well. Keep Knee-Intensive Exercise Balanced for Cartilage Support.
Studies show that high-intensity cycling and running for 12 weeks can promote wear and tear on the cartilage and reduce its content by as much as 1. The participants were all young, healthy individuals. On the other hand, both of these exercises have been shown to increase cartilage density over the course of a week, while squats had no effect on cartilage density at all.
If done at a high intensity on a consistent basis, these may increase the risk of early cartilage degeneration and osteoarthritis later in life. Build a Wide Variety of Exercises to Allow for Better Regeneration.
Repetitive exercise is great for muscle building, yet excessive amounts on a daily basis can also increase the risk of injury and promote wear and tear on cartilage and bone.
Alternating exercises daily and opting for a wider variety of physical activity can help to lessen the load on selective muscles and bones, give more time for repair in between, as well as help to build upon a more balanced selection of them. It might help to be able to choose from a range of different stretches, balance-enhancing exercises, muscle-building exercises, and aerobics both indoors and outdoorsas well as physical activities that are enjoyable, such as swimming, walkingor cycling.
Muscle, bone, and cartilage are intimately connected and depend upon physical activity to grow and be well maintained. Muscle building helps to increase muscle strength and mass, which, alongside gravity and the pressure exerted by weight-bearing exercise, contributes an additional force that improves bone density and strength.
The aging process slows muscle building down and lends itself towards reductions in muscle strength and quality, irrespective of physical activity levels. Hence, consistent muscle building from young adulthood has far-reaching benefits and is capable of delaying bone and muscle aging by acting as a buffer against muscle and bone losses.
Bone responds to localized muscle activity; therefore, it is important to opt for full-body workouts in order to improve overall bone strength and density.

Muscle preservation and bone density -
Data that is raising concern about sarcopenia as it relates to GLP-1 drugs is driven by a small portion of participants who underwent DEXA dual-energy X-ray absorptiometry , which measures bone mineral density using spectral imaging, said Dr.
Karl Nadolsky , endocrinologist and diplomate at the American Board of Obesity Medicine. Nadolsky pointed out that rapid weight loss, in general, will reduce resting metabolic rate to some degree.
Because the weight loss process on GLP-1s is so fast, she said people need to be extra vigilant in their nutritional intake, specifically increasing their intake of protein , to avoid sarcopenic obesity.
The following lifestyle changes can help prevent a decrease in muscle mass and bone density while losing weight fast for those who take GLP-1 medications like Ozempic or Wegovy. A systematic review and meta-analysis found that dietary trials with higher protein result in less lean mass loss and more fat mass loss compared to lower protein intake.
To maximize muscle preservation during active weight loss, Kumar said to focus on consuming grams of protein per meal.
Additionally, adding beans to salads, choosing quinoa over rice or pasta, and supplementing with protein powders and drinks are good ways to get more protein.
Resistance training mitigates all muscle loss that occurs during caloric restriction, according to a meta-analysis.
She suggests starting with strength workouts per week. Healthy, restorative, and consistent sleep patterns impact various hormones involved in body weight regulation and muscle strength, such as cortisol and growth hormone, said Kumar.
Nadolsky said physicians need to embrace the potential adverse effects of some lean mass loss when they are treating people with obesity and help patients mitigate that with resistance training and protein optimization.

Here are…. You can reduce your chances of falling by exercising to build your muscle strength and improve your balance. Exercise can also slow the rate of bone loss, which reduces the risk of fractures from osteoporosis. Exercise also brings other benefits to people who have osteoporosis or want to prevent osteoporosis.
These include reduced need for some medications that can contribute to the risk of falls, and better management of other health problems. A sedentary lifestyle, poor posture, poor balance and weak muscles increase the risk of fractures.
A person with osteoporosis can improve their health with exercise in valuable ways, including:. Always consult with your doctor , physiotherapist , exercise physiologist or health care professional before you decide on an exercise program. Factors that need to be considered include:. A combination of weight-bearing impact loading, aerobic and muscle-building resistance exercise is best, together with specific balance exercises.
Swimming and water exercise such as aqua aerobics or hydrotherapy are not weight-bearing exercises, because the buoyancy of the water counteracts the effects of gravity.
However, exercising in water can improve your cardiovascular fitness and muscle strength. People with severe osteoporosis or kyphosis hunching of the upper back who are at high risk of bone fractures may find that swimming or water exercise is their preferred activity. Consult with your doctor or healthcare professional.
Even though walking is a weight-bearing exercise, it does not greatly improve bone health, muscle strength, or balance. However, for people who are otherwise inactive, walking may be a safe way to introduce some physical activity.
A person with osteoporosis has weakened bones that are prone to fracturing. They should avoid activities that:. The exact amount of exercise required for people with osteoporosis is currently unknown. However, guidelines suggest:. You need to continue your exercises over the long term to reduce your chances of a bone fracture.
Please consult with a physiotherapist or exercise physiologist for further advice. Regular exercise is an essential part of any osteoporosis treatment program.
See your doctor before starting a new exercise program. Physiotherapists and other exercise professionals can give you expert guidance. Always start your exercise program at a low level and progress slowly.
