At Caffiene same time, caffeine has become ubiquitous Caffeind the sporting world, where there is keen interest in bwnefits understanding the impact of caffeine on various benefitz of exercise performance.

Accordingly, caffeine has dominated the ergogenic aids and sport supplement research Caffelne over the past several decades [ 1112 Caffeime, 13 ]. In the Czffeine days s of modern sport, concoctions of plant-based stimulants, including caffeine and other compounds such as cocaine, strychnine, Dietary changes for cholesterol control, bfnefits and nitroglycerin, Cffeine developed secretly by Caloric needs for digestive health, athletes and coaches, in what appears to be evidence for early day ergogenic aids designed to provide a competitive benfits [ 14 ].

To date, the preponderance of caffeine and exercise performance literature has utilized anhydrous caffeine in a capsule [ 40414243444546 ] for simpler dose standardization and placebo creation.

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].

What does caffeine do to your body?

One study also found that people who consumed coffee were more likely to be physically active. Some studies have found that drinking coffee could be associated with a lower risk of depression.

Another study found that drinking at least four cups of coffee each day was associated with a significantly lower risk of depression, compared with drinking just one cup per day Several studies have found that coffee could be linked to a lower risk of depression and may even be linked to a lower risk of death by suicide.

Interestingly, several studies suggest that coffee could support liver health and protect against disease. For instance, one study found that drinking more than two cups of coffee per day was linked to lower rates of liver scarring and liver cancer in people with liver disease Other research shows that the more coffee people drank, the lower their risk of death from chronic liver disease.

Another recent study found that coffee consumption was associated with decreased liver stiffness, which is a measure healthcare professionals use to assess fibrosis, the formation of scar tissue in the liver Coffee consumption could be linked to a decreased risk of death from chronic liver disease, along with other conditions, like liver scarring and liver cancer.

However, keep in mind that caffeine could affect blood pressure levels. Therefore, people with unmanaged blood pressure may need to limit or moderate their caffeine intake 23 , Some research shows that drinking coffee could be linked to a lower risk of heart disease, stroke, and heart failure. Some research suggests that coffee could help extend longevity, thanks to its multitude of potential health benefits.

For example, one review of 40 studies concluded that drinking two to four cups of coffee daily was associated with a lower risk of death, regardless of factors like age, weight status, and alcohol consumption Similarly, another study in 1, people found that drinking caffeinated coffee was linked to a lower risk of death after 12 and 18 years of follow-up.

Furthermore, drinking at least one cup of coffee per day was also associated with a lower risk of death from cancer Interestingly, one test-tube study showed that coffee was able to significantly extend the life span of yeast by protecting against free radicals and DNA damage Coffee could be associated with a lower risk of death, regardless of other factors, like age, weight status, or alcohol consumption.

Still, more research is needed. Coffee is often used as an ergogenic aid by athletes looking to improve performance and increase energy levels Another study in older adults found that drinking coffee was associated with improved physical performance and faster gait speed, even after the researchers adjusted for factors like age, belly fat, and physical activity levels Additionally, a large review reported that moderate caffeine consumption could slightly improve power output and time-trial completion time.

However, results varied, so the researchers also noted that caffeine may affect people differently Coffee could improve physical performance and endurance when consumed before exercising. However, some studies have turned up mixed results.

Coffee is a popular beverage that researchers have studied extensively for its many health benefits, including its ability to increase energy levels, promote weight management, enhance athletic performance, and protect against chronic disease. Keep in mind that some people may need to limit their intake, including people who are pregnant or breastfeeding, children and adolescents, and people with certain health conditions Still, drinking coffee in moderation — about three to four cups per day — has been associated with several health benefits and is generally considered safe for most adults Try this today: One way to maximize the benefits of your daily cup of joe is to switch up your sweetener.

Instead of using sugar or flavored syrups, opt for a naturally derived low calorie sweetener like stevia, or add a dash of cinnamon for flavor.

Decaffeinated coffee is a good option if one is sensitive to caffeine, and according to the research summarized above, it offers similar health benefits as caffeinated coffee.

The extra calories, sugar, and saturated fat in a coffee house beverage loaded with whipped cream and flavored syrup might offset any health benefits found in a basic black coffee.

Coffee beans are the seeds of a fruit called a coffee cherry. Coffee cherries grow on coffee trees from a genus of plants called Coffea.

There are a wide variety of species of coffee plants, ranging from shrubs to trees. Decaffeinated coffee. This is an option for those who experience unpleasant side effects from caffeine.

The two most common methods used to remove caffeine from coffee is to apply chemical solvents methylene chloride or ethyl acetate or carbon dioxide gas. Both are applied to steamed or soaked beans, which are then allowed to dry.

According to U. Both methods may cause some loss of flavor as other naturally occurring chemicals in coffee beans that impart their unique flavor and scent may be destroyed during processing.

However, adding sugar, cream, and milk can quickly bump up the calorie counts. A tablespoon of cream contains 52 calories, and a tablespoon of whole milk contains 9 calories. However, the real caloric danger occurs in specialty mochas, lattes, or blended ice coffee drinks.

Coffee and Health Coffee is an intricate mixture of more than a thousand chemicals. Cancer Coffee may affect how cancer develops, ranging from the initiation of a cancer cell to its death.

Type 2 Diabetes Although ingestion of caffeine can increase blood sugar in the short-term, long-term studies have shown that habitual coffee drinkers have a lower risk of developing type 2 diabetes compared with non-drinkers. In a meta-analysis of 45, people with type 2 diabetes followed for up to 20 years, an association was found with increasing cups of coffee and a lower risk of developing diabetes.

Caffeinated coffee showed a slightly greater benefit than decaffeinated coffee. Heart health Caffeine is a stimulant affecting the central nervous system that can cause different reactions in people. The authors found no such association with other caffeinated drinks such as tea and soda. These coffee-specific results suggest that components in coffee other than caffeine may be protective.

Heavier coffee intake of 6 or more cups daily was neither associated with a higher nor a lower risk of cardiovascular disease. Depression Naturally occurring polyphenols in both caffeinated and decaffeinated coffee can act as antioxidants to reduce damaging oxidative stress and inflammation of cells.

to 2 cups of coffee. found a decreasing risk of suicide with increasing coffee consumption. There was no association between decaffeinated coffee and suicide risk, suggesting that caffeine was the key factor, rather than plant compounds in coffee.

There is consistent evidence from epidemiologic studies that higher consumption of caffeine is associated with lower risk of developing PD. The caffeine in coffee has been found in animal and cell studies to protect cells in the brain that produce dopamine.

In that time, after adjusting for known risks of PD, those who drank at least 10 cups of coffee a day had a significantly lower risk of developing the disease than non-drinkers. Women showed the lowest risk when drinking moderate intakes of cups coffee daily.

The authors stated the need for larger studies with longer follow-up periods. Gallstones There are various proposed actions of caffeine or components in coffee that may prevent the formation of gallstones.

Mortality In a large cohort of more than , participants followed for up to 30 years, an association was found between drinking moderate amounts of coffee and lower risk of early death.

Both caffeinated and decaffeinated coffee provided benefits. The authors suggested that bioactive compounds in coffee may be responsible for interfering with disease development by reducing inflammation and insulin resistance.

The protective effect was present regardless of a genetic predisposition to either faster or slower caffeine metabolism. Instant and decaffeinated coffee showed a similar health benefit.
