A review of alternate caffeine forms may be found in the Alternative caffeine sources section and Tables 4567 and 8. Anti-doping rules apply to most sports, especially in those where athletes are competing at national and international levels. The IOC continues to recognize that caffeine is frequently used by athletes because of its reported performance-enhancing or ergogenic effects [ ].
Caffeine was added to the list of banned substances by the IOC in and the World Anti-Doping Agency WADA in The cut-off value was chosen to exclude typical amounts ingested as part of common dietary or social coffee drinking patterns, and to differentiate it from what was considered to be an aberrant use of caffeine for the purpose of sports performance enhancement [ ].
The highest use of caffeine was among endurance athletes in both studies []. Urinary caffeine concentration significantly increased from to in athletics, aquatics, rowing, boxing, judo, football, and weightlifting; however, the sports with the highest urine caffeine concentration in were cycling, athletics, and rowing [ ].
Caffeine or 1,3,7-trimethylxanthine, is an odorless white powder that is soluble in both water and lipids and has a bitter taste. It is rapidly absorbed from the gastrointestinal tract, mainly from the small intestine but also in the stomach [ ].
Caffeine is effectively distributed throughout the body by virtue of being sufficiently hydrophobic to allow easy passage through most, if not all biological membranes, including the blood-brain barrier [ ].
Once caffeine is absorbed, there appears to be no hepatic first-pass effect i. Caffeine absorption from food and beverages does not seem to be dependent on age, gender, genetics or disease, or the consumption of drugs, alcohol or nicotine.
However, the rates of caffeine metabolism and breakdown appear to differ between individuals through both environmental and genetic influences [ 3, ]. The wide range of variability in caffeine metabolism is due to several factors. Several studies have also shown that the form of caffeine or its vehicle for entry into the body can modify the pharmacokinetics [ 5881, ].
Liguori et al. The impact of temperature or rate of ingestion of caffeine has also been investigated, amidst concerns that cold energy drinks might pose a danger when chugged quickly, compared to sipping hot coffee. Similar to other caffeine pharmacokinetic studies [], White et al. energy drink may be associated with slight differences in pharmacokinetic activity, these differences are small.
Chewing gum formulations appear to alter pharmacokinetics, as much of the caffeine released from the gum through mastication can be absorbed via the buccal cavity, which is considered faster due to its extensive vascularization, especially for low molecular weight hydrophobic agents [ ].
Kamimori et al. These pharmacokinetic findings are useful for military and sport purposes, where there is a requirement for rapid and maintained stimulation over specific periods of time. Chewing gum may also be advantageous due to reduced digestive requirements, where absorption of caffeine in other forms capsule, coffee etc.
may be hindered by diminished splanchnic blood flow during moderate to intense exercise. Finally, there is a growing prevalence of caffeinated nasal and mouth aerosols administered directly in the mouth, under the tongue or inspired may affect the brain more quickly through several proposed mechanisms [ 5 ], although there are only a few studies to date to support this claim.
The administration of caffeine via aerosol into the oral cavity appears to produce a caffeine pharmacokinetic profile comparable to the administration of a caffeinated beverage [ 81 ].
Nasal and mouth aerosols will be discussed further in another section. Although the action of caffeine on the central nervous system CNS has been widely accepted as the primary mechanism by which caffeine alters performance, several mechanisms have been proposed to explain the ergogenic effects of caffeine, including increased myofibrillar calcium availability [], optimized exercise metabolism and substrate availability [ 45 ], as well as stimulation of the CNS [, ].
One of the earlier proposed mechanisms associated with the ergogenic effects of caffeine stemmed from the observed adrenaline epinephrine -induced enhanced free-fatty acid FFA oxidation after caffeine ingestion and consequent glycogen sparing, resulting in improved endurance performance [ 1845].
However, this substrate-availability hypothesis was challenged and eventually dismissed, where after several performance studies it became clear that the increased levels of FFAs appeared to be higher earlier in exercise when increased demand for fuel via fat oxidation would be expected [, ].
Furthermore, this mechanism could not explain the ergogenic effects of caffeine in short duration, high-intensity exercise in which glycogen levels are not a limiting factor.
RER, changes in blood lactate, glucosealso appear to deliver measurable ergogenic effects, offering strong support for the CNS as the origin of reported improvements [ 43, ]. As such, focus has shifted to the action of caffeine during exercise within the central and peripheral nervous systems, which could alter the rate of perceived exertion RPE [,], muscle pain [,], and possibly the ability of skeletal muscle to generate force [ ].
Caffeine does appear to have some direct effects on muscle which may contribute to its ergogenicity. Caffeine appears to employ its effects at various locations in the body, but the most robust evidence suggests that the main target is the CNS, which is now widely accepted as the primary mechanism by which caffeine alters mental and physical performance [ ].
Caffeine is believed to exert its effects on the CNS via the antagonism of adenosine receptors, leading to increases in neurotransmitter release, motor unit firing rates, and pain suppression [, ]. There are four distinct adenosine receptors, A 1A 2AA 2B and A 3that have been cloned and characterized in several species [ ].
Of these subtypes, A 1 and A 2A, which are highly concentrated in the brain, appear to be the main targets of caffeine [ ].
Adenosine is involved in numerous processes and pathways, and plays a crucial role as a homeostatic regulator and neuromodulator in the nervous system [ ]. The major known effects of adenosine are to decrease the concentration of many CNS neurotransmitters, including serotonin, dopamine, acetylcholine, norepinephrine and glutamate [, ].
Caffeine, which has a similar molecular structure to adenosine, binds to adenosine receptors after ingestion and therefore increases the concentration of these neurotransmitters []. This results in positive effects on mood, vigilance, focus, and alertness in most, but not all, individuals [].
Researchers have also characterized aspects of adenosine A 2A receptor function related to cognitive processes [ ] and motivation []. In particular, several studies have focused on the functional significance of adenosine A 2A receptors and the interactions between adenosine and dopamine receptors, in relation to aspects of behavioral activation and effort-related processes [,].
The serotonin receptor 2A 5-HT2A has also been shown to modulate dopamine release, through mechanisms involving regulation of either dopamine synthesis or dopaminergic neuron firing rate []. Alterations in 5-HTR2A receptors may therefore affect dopamine release and upregulation of dopamine receptors [].
This may therefore modulate dopamine activity, which may help to elucidate some of the relationships among neurotransmitters, genetic variation and caffeine response, and the subsequent impact on exercise performance. Muscle pain has been shown to negatively affect motor unit recruitment and skeletal muscle force generation proportional to the subjective scores for pain intensity [].
In one study, progressively increased muscle pain intensity caused a gradual decrease in motor firing rates [ ]. However, this decrease was not associated with a change in motor unit membrane properties demonstrating a central inhibitory motor control mechanism with effects correlated to nociceptive activity [ ].
Other studies also indicate that muscle force inhibition by muscle pain is centrally mediated [ ]. Accordingly, caffeine-mediated CNS mechanisms, such as dopamine release [ ], are likely imputable for pain mitigation during high-intensity exercise [,,].
Although there appears to be strong evidence supporting the analgesic effects of caffeine during intense exercise, others have found no effect []. The attenuation of pain during exercise as a result of caffeine supplementation may also result in a decrease in the RPE during exercise.
Two studies [] have reported that improvements in performance were accompanied by a decrease in pain perception as well as a decrease in RPE under caffeine conditions, but it is unclear which factor may have contributed to the ergogenic effect.
Acute caffeine ingestion has been shown to alter RPE, where effort may be greater under caffeine conditions, yet it is not perceived as such [ 12,]. Others have not found changes in RPE with caffeine use [ ]. A more recent study by Green et al. The authors noted that individual responses to caffeine might explain their unexpected findings.
In the last decade, our understanding of CNS fatigue has improved. When caffeine and NECA were given together, the effects appeared to cancel each other out, and run time was similar to placebo.
When the study was repeated with peripheral intraperitoneal body cavity injections instead of brain injections, there was no effect on run performance. The authors concluded that caffeine increased running time by delaying fatigue through CNS effects, in part by blocking adenosine receptors [ ].
Caffeine also appears to enhance cognitive performance more in fatigued than well-rested subjects [, ]. This phenomenon is also apparent in exercise performance [ ] both in the field [ ] and in the lab [ 6063].

So, for athletes, it is recommended that they opt for pure caffeine in the form of a capsule, chewing gum or gel. However, the overall prevalence of caffeine supplementation was closer to the one reported here. |
| Caffeine: Caffeine may boost athletic performance, study finds - The Economic Times | And, if that isn't enough, it's also believed to enhance the body's ability to use its own fat as fuel, which can effectively increase the time to exhaustion in endurance events. To get a little nerdy and "sciencey" for a second, the theory is that caffeine blocks something called adenosine receptors in the brain. That leads to higher levels of dopamine and noradrenaline, which both can lead to all the aforementioned magical performance-boosting benefits. It's believed that the easiest and most effective way to get a performance boost is by first allowing your body to regain its natural state of sensitivity to caffeine. That was the theory back in my racing days, and it holds true in most circles today. That means going cold-turkey for ten days to two weeks. But in , a study in the Journal of Applied Physiology from the University of São Paulo, tested that assumption. Researchers put 40 well-trained cyclists through a series of time trial events. And these lucky folks only had to abstain from caffeine for 24 hours before each event! At the beginning of the study, each of the cyclists was asked about their caffeine-drinking habits. The initial assumption for the study was that the lesser-caffeinated cyclists would experience the biggest boost in performance. And the higher-caffeinated group would see the lowest boost—especially since the abstinence period was so short 24 hours. Contrast that with the two weeks of caffeine deprivation I inflicted upon myself! Not surprisingly, the caffeine did boost everyone's performance and speed by 2. It also boosted everyone's performance 3. Your fueling strategy should focus first and foremost on replacing the three acute costs of taking part in endurance sport , namely carbohydrates , sodium and fluid. How you replace each of these will be very individual to you, but the science suggests that all athletes will benefit from an appropriate level of replenishment of each. Whether you use caffeine or not will come down to your personal preference, previous experiences, sensitivity, tolerance, and habitual use of caffeine. For example, aim to prioritise quality diet and sleep and manage your pre-race stress levels. during an IRONMAN or ultramarathon , then you may wish to experiment with including some in your pre-training routine , or during very long training sessions. If just 1 out of the 3 factors is true for you, then you may want to carefully consider whether introducing caffeine into your training or racing is the right thing for you. If you decide you want to use caffeine, build up your intake gradually. If all 3 factors are true then the risk of utilising caffeine in your racing or training is likely to be small. That said, be sensible and follow the recommended pre- and during exercise usage guidelines. This is because the average half life of caffeine - i. e the time it takes for the concentration of a substance to halve in the body - is hours though some individuals metabolise it much quicker and slower than this. Within 15 to 20 minutes, it is absorbed into the blood via the mucous membranes of the mouth. So, you must individually choose between these products by weighing up the pros and cons based on the intended effects, dose, timing and practical feasibility. An overview of the advantages and disadvantages of the different products is given in Table 1. Regardless of the product chosen, the effects wear off gradually. Caffeine is, eventually, removed from the blood completely after 3 to 5 hours. Guarana is a herb that grows in the Amazon basin that contains caffeine and is regularly incorporated in energy or diet supplements. An average portion of guarana contains about just as much caffeine as half a cup of coffee. Numerous claims have been made that this supplement improves athletic performance. However, convincing proof is lacking at this time. In fact, little is known about the effects on health or the possible side effects of guarana compared to the abundance of studies on the use of caffeine. So, until more research has been completed, it recommended that athletes choose pure caffeine supplements. Table 1: Caffeine-rich products with their dose per portion, timing of absorption, advantages, and disadvantages. Caffeine can improve both endurance performance and short repetitive all-out exertions. This supplement can also have certain positive effects during ball and team sports. This requires a dose of 2 to 6 mg of caffeine per kg of body weight. In addition, there is increasing evidence that lower doses produce performance improvements. The optimal dose differs per individual, due to habituation and genetic differences, among other things. The amount required can be attained by using a variety of products. So, you must carefully weigh up your choice based on the intended effects, dose, timing, and practical feasibility.

| Caffeine and sports performance: Pros, cons and considerations | Caffeine levels remain high for 3—4 hours and then start to drop 1. Unlike most substances and supplements , caffeine can affect cells throughout your body, including muscle and fat cells, as well as cells within your central nervous system 5. Caffeine is eventually broken down in the liver 1. Caffeine can easily pass throughout your body. It has varied effects on your hormones, muscles, and brain. Due to its positive effects on exercise performance, some organizations — such as the National Collegiate Athletic Association NCAA — have even started to ban it in high doses. One large review of studies found that caffeine modestly improves endurance when used in moderate doses of 1. In one study, trained cyclists who consumed either and mg doses of caffeine along with a carbohydrate-electrolyte solution late in exercise completed a time trial faster than those who consumed only the carbohydrate-electrolyte solution. Other research examined the effect of coffee due to its naturally high levels of caffeine. Research suggests both caffeine and caffeinated coffee produce similar benefits for endurance exercise performance Some research suggests that a genetic variation that affects how you metabolize caffeine may determine the extent to which caffeine improves your endurance performance. In one study, competitive male athletes consumed either 0. All who consumed caffeine experienced performance improvements. Although, those with the genetic variation experienced significantly greater dose-dependent improvements in endurance performance than those without the genetic variation Caffeine and coffee can both significantly improve performance for endurance athletes. A genetic variation may determine the extent to which caffeine improves your endurance performance. Caffeine has impressive benefits for trained athletes, but it may offer less significant benefits for beginners or those who are untrained In one small, well-designed study, men who participated in high intensity cycling felt less fatigued and were able to continue cycling longer after consuming 1. However, in another study, supplementing with mg of caffeine or coffee along with creatine did not improve sprint performance in physically active males A review of studies showed that consuming 1. For high intensity sports like cycling or swimming, caffeine may benefit trained athletes more than untrained individuals. Although several studies have found a positive effect, the evidence is inconclusive 23 , 24 , In one study, 12 participants performed bench presses after consuming 1. After consuming caffeine, participants demonstrated significantly increased force and power output compared with a placebo In another study, 12 people who regularly consumed caffeine consumed either a placebo or 1. Compared with a placebo, consuming caffeine increased mean power output and mean bar velocity when performing 5 sets of a bench press throw However, in one small but well-designed study, ingestion of caffeine prior to a workout did not significantly affect muscle strength, as measured by handgrip strength, among CrossFit athletes Another study looked at whether consuming a high dose of caffeine improves muscle strength in male athletes who regularly drank coffee. Taking a high dose of caffeine did not significantly affect their maximum bench press strength compared with a placebo Overall, studies indicate that caffeine may provide benefits for power-based activities, but more research is needed to confirm this. Caffeine may help improve performance in strength or power-based exercises, but study results are mixed. Caffeine is a common ingredient in weight loss supplements. Caffeine also modestly increases your daily calorie expenditure One review of studies showed that consuming 1. However, no evidence suggests that caffeine consumption promotes significant weight loss. Caffeine can help release stored fat from fat cells, especially before and at the end of a workout. It can also help you burn more calories. If you regularly consume coffee, energy drinks, caffeinated soda, or dark chocolate , you may experience fewer benefits from caffeine supplements. This is because your body has developed a tolerance to caffeine Research suggests both caffeine anhydrous supplements and regular coffee provide benefits for exercise performance When supplementing with caffeine, the dose is often based on body weight, set at around 1. As far as psychoactive drugs go, caffeine is considered safe for consumption and is regarded as less addictive than other commonly used drugs like tobacco. But anyone who enjoys a cup of coffee knows that caffeine can have its downsides. There can also be side-effects from consuming too much caffeine or timing your intake poorly, including anxiety, headaches, nausea, jitters and insomnia. Your experience of the potential side-effects will be influenced by your individual tolerance to caffeine, which varies widely from person to person. Sensitivity and tolerance boils down to genetic variations in the enzyme which metabolises caffeine in your liver. As a result, they can be more susceptible to its negative side effects. Your fueling strategy should focus first and foremost on replacing the three acute costs of taking part in endurance sport , namely carbohydrates , sodium and fluid. How you replace each of these will be very individual to you, but the science suggests that all athletes will benefit from an appropriate level of replenishment of each. Whether you use caffeine or not will come down to your personal preference, previous experiences, sensitivity, tolerance, and habitual use of caffeine. For example, aim to prioritise quality diet and sleep and manage your pre-race stress levels. during an IRONMAN or ultramarathon , then you may wish to experiment with including some in your pre-training routine , or during very long training sessions.
