| 5 Foods That Naturally Enhance Athletic Performance | Even a short period of carbohydrate restriction can affect your bone health. This happens by lowering the number of bone-building substances while increasing the amount of elements that break down your bones. Overall, this can lead to weaker bones. Aim to fill your plate half full of carbohydrate foods such as pasta, bread, rice, potatoes, quinoa, couscous and others. This guide is designed to be used for meals only. You will most likely also need to eat snacks between meals to keep your energy levels up. Snacks play a crucial role in fueling an athlete. Due to the high training demand of sports and recreational activities, it can be difficult to get enough fuel by consuming only 3 meals daily. If you play a sport or engage in physical activity often, snacks per day between meals can help you stay energized and on top of your performance. Here are some snack ideas:. Staying well-hydrated is essential for athletes. Athletes need different amounts of hydration depending on their body size, what sport they do, how much they sweat and where they train. Read more about exactly how much water you should be drinking as an athlete. You may need to consume carbohydrates and fluids to keep your energy level up during activity sessions. If your training session is longer than 1 hour, in hot and humid weather, high intensity or if you can't make it through your workout, you will benefit from consuming these nutrients during your workout. However, this may lead to digestive issues if your stomach isn't used to it. When you train your gut, you are allowing your stomach to practice using this fuel during training, which can reduce digestive issues and improve nutrient delivery to your muscles. Like any other athletic activity, training your gut takes practice and builds over time. Here are some steps to take:.

Skip Navigation Home News Room Blogs 7 Ways to Turbocharge Your Athletic Performance. Print Share. Make sure you eat enough. Choose whole foods often. Choose Greek yogurt for your fruit smoothie instead of protein powder. Greek yogurt has about 20 grams of protein in a single cup. Opt for a granola bar and cheese stick instead of a protein bar. Protein bars sometimes contain ingredients that can upset your stomach, like artificial fibers. Grill some chicken breasts instead of using collagen powder. Here are some snack ideas: A peanut butter and honey sandwich on whole-wheat bread is a delicious way to get in carbohydrates, fiber, fats and protein between meals. A homemade Lunchable with crackers, cheese and deli meat is an easy, energy-sustaining snack. A tall glass of electrolyte-packed chocolate milk can replenish your body following an intense activity session. Pair a pack of fruit snacks with some nuts for a quick and convenient option. Monitor your hydration. Check your urine: Look at how much and what color your urine is. It should be a light yellow, like lemonade, not clear. Monitor your weight loss around practice: If appropriate, you can weigh yourself before and after you play. Weight loss during activity will generally only be from sweating. Some are involved in the function of skeletal muscles, while others play roles in the production of energy for cells, communication between nerve cells, or other cellular processes. Other studies have examined variations across the entire genomes an approach called genome-wide association studies or GWAS of elite athletes to determine whether specific areas of the genome are associated with athleticism. More than different variations linked to athletic performance have been identified in these studies; however, most have been found in only one or a few studies, and the significance of most of these genetic changes have not been identified. It is likely that a large number of genes are involved, each of which makes only a small contribution to athletic performance. Athletic performance is also strongly influenced by the environment. For example, if a child and his or her parent excel at a sport, is that similarity due to genetic factors passed down from parent to child, to similar environmental factors, or most likely to a combination of the two? It is clear that both environmental and genetic factors play a part in determining athletic ability. Ahmetov II, Egorova ES, Gabdrakhmanova LJ, Fedotovskaya ON.

| 5 Foods That Naturally Enhance Athletic Performance | Creatine supplementation may reduce the range of motion of various parts of the body such as the shoulders, ankles, and lower legs and lead to muscle stiffness and resistance to stretching [ ]. However, performance benefits are more modest in exercise tests lasting more than 4 minutes because aerobic metabolic pathways increasingly meet energy demands. The mechanisms by which quercetin might enhance exercise and athletic performance when taken in much larger amounts are not known, but many have been hypothesized. Several growth factors have been detected in deer antler velvet, such as IGF-1, that could promote muscle tissue growth in a similar way to the quick growth of deer antlers.

Athletic performance -
The B. in athletic performance builds a science-based approach for promoting health and improving athletic performance in the health and fitness industries and beyond. This program is designed for scholar athletes and students interested in sports professions, fitness training, and careers within the health industry.
Extensive experiential learning is central to the B. in athletic performance. The program integrates exercise science and psychology to prepare students for a holistic approach to athletic performance. Water is a suitable drink, but sports drinks may be required, especially in endurance events or warm climates.
Sports drinks contain some sodium, which helps absorption. While insufficient hydration is a problem for many athletes, excess hydration may also be potentially dangerous. In rare cases, athletes might consume excessive amounts of fluids that dilute the blood too much, causing a low blood concentration of sodium.
This condition is called hyponatraemia, which can potentially lead to seizures, collapse, coma or even death if not treated appropriately. Consuming fluids at a level of to ml per hour of exercise might be a suitable starting point to avoid dehydration and hyponatraemia, although intake should ideally be customised to individual athletes, considering variable factors such as climate, sweat rates and tolerance.

Daily training diet requirements The basic training diet should be sufficient to: provide enough energy and nutrients to meet the demands of training and exercise enhance adaptation and recovery between training sessions include a wide variety of foods like wholegrain breads and cereals , vegetables particularly leafy green varieties , fruit , lean meat and low-fat dairy products to enhance long term nutrition habits and behaviours enable the athlete to achieve optimal body weight and body fat levels for performance provide adequate fluids to ensure maximum hydration before, during and after exercise promote the short and long-term health of athletes.
Carbohydrates are essential for fuel and recovery Current recommendations for carbohydrate requirements vary depending on the duration, frequency and intensity of exercise.
Eating during exercise During exercise lasting more than 60 minutes, an intake of carbohydrate is required to top up blood glucose levels and delay fatigue.
Eating after exercise Rapid replacement of glycogen is important following exercise. Protein and sporting performance Protein is an important part of a training diet and plays a key role in post-exercise recovery and repair.
For example: General public and active people — the daily recommended amount of protein is 0. Sports people involved in non-endurance events — people who exercise daily for 45 to 60 minutes should consume between 1. Sports people involved in endurance events and strength events — people who exercise for longer periods more than one hour or who are involved in strength exercise, such as weight lifting, should consume between 1.
Athletes trying to lose weight on a reduced energy diet — increased protein intakes up to 2. While more research is required, other concerns associated with very high-protein diets include: increased cost potential negative impacts on bones and kidney function increased body weight if protein choices are also high in fat increased cancer risk particularly with high red or processed meat intakes displacement of other nutritious foods in the diet, such as bread, cereal, fruit and vegetables.
Using nutritional supplements to improve sporting performance A well-planned diet will meet your vitamin and mineral needs.
Nutritional supplements can be found in pill, tablet, capsule, powder or liquid form, and cover a broad range of products including: vitamins minerals herbs meal supplements sports nutrition products natural food supplements.

For a general overview, see our consumer fact sheet. This fact sheet provides an overview of selected ingredients in dietary supplements designed or claimed to enhance exercise and athletic performance. Manufacturers and sellers promote these products, sometimes referred to as ergogenic aids, by claiming that they improve strength or endurance, increase exercise efficiency, achieve a performance goal more quickly, and increase tolerance for more intense training.
These effects are the main focus of this fact sheet. Some people also use ergogenic aids to prepare the body for exercise, reduce the chance of injury during training, and enhance recovery from exercise [ 1 , 2 ].
Dietary supplements to enhance exercise and athletic performance come in a variety of forms, including tablets, capsules, liquids, powders, and bars. Many of these products contain numerous ingredients in varied combinations and amounts.
Among the more common ingredients are amino acids, protein, creatine, and caffeine. Several surveys have indicated the extent of dietary supplement use for bodybuilding and to enhance exercise and athletic performance:.
It is difficult to make generalizations about the extent of dietary supplement use by athletes because the studies on this topic are heterogeneous. However, the data suggest that [ 9 ]:. For any individual to physically perform at his or her best, a nutritionally adequate diet and sufficient hydration are critical.
The Dietary Guidelines for Americans [ 10 ] and MyPlate [ 11 ] recommend such an eating plan for everyone. Athletes require adequate daily amounts of calories, fluids, carbohydrates to maintain blood glucose levels and replace muscle glycogen; typically 1.
A few dietary supplements might enhance performance only when they add to, but do not substitute for, this dietary foundation. Athletes engaging in endurance activities lasting more than an hour or performed in extreme environments e.
Even with proper nutritional preparation, the results of taking any dietary supplement s for exercise and athletic performance vary by level of training; the nature, intensity, and duration of the activity; and the environmental conditions [ 13 ].
Sellers claim that dozens of ingredients in dietary supplements can enhance exercise and athletic performance. Well-trained elite and recreational athletes might use products containing one or more of these ingredients to train harder, improve performance, and achieve a competitive edge.
However, the National Athletic Trainers' Association acknowledges in a position statement that because the outcomes of studies of various performance-enhancing substances are often equivocal, using these substances can be controversial and confusing [ 14 ].
Most studies to assess the potential value and safety of supplements to enhance exercise and athletic performance include only conditioned athletes.
Therefore, it is often not clear whether the supplements discussed in this fact sheet may be of value to recreational exercisers or individuals who engage in athletic activity only occasionally.
In addition, much of the research on these supplements involves young adults more often male than female and not adolescents who may also use them against the advice of pediatric and high-school professional associations [ 7 , 15 ].
The quality of many studies is limited by their small samples and short durations, use of performance tests that do not simulate real-world conditions or are unreliable or irrelevant, and poor control of confounding variables [ 12 ].
Furthermore, the benefits and risks shown for the supplements might not apply to the supplement's use to enhance types of physical performance not assessed in the studies. In most cases, additional research is needed to fully understand the efficacy and safety of particular ingredients. Many exercise and athletic-performance dietary supplements in the marketplace contain multiple ingredients especially those marketed for muscle growth and strength.
However, much of the research has focused only on single ingredients. One, therefore, cannot know or predict the effects and safety of combinations in these multi-ingredient products unless clinical trials have investigated that particular combination. Furthermore, the amounts of these ingredients vary widely among products.
In some cases, the products contain proprietary blends of ingredients listed in order by weight, but labels do not provide the amount of each ingredient in the blend. Manufacturers and sellers of dietary supplements for exercise and athletic performance rarely fund or conduct scientific research on their proprietary products of a caliber that reputable biomedical journals require for publication.
Table 1 briefly summarizes the findings discussed in more detail in this fact sheet on the safety and efficacy of selected ingredients in dietary supplements to enhance exercise and athletic performance. Some research-derived data are available on these ingredients on which to base a judgment about their potential value to aid exercise and athletic performance.
These dietary supplement ingredients are listed and discussed in the table, and in the text that follows the table, in alphabetical order. The efficacy and safety of these ingredients might be different when they are combined with other ingredients in a product or training plan.
In the text below, each ingredient's section begins with an introduction, followed by a summary of the scientific evidence of that ingredient's efficacy and safety. Each section concludes with information and advice from expert sources, when available, on use of the ingredient as an ergogenic aid.
In theory, free radicals could impair exercise performance by impeding muscles' ability to produce force, thereby accelerating muscle damage and fatigue and producing inflammation and soreness [ ].
Some researchers have suggested that supplements containing antioxidants, such as vitamins C and E and coenzyme Q 10 CoQ 10 , could reduce this free-radical formation, thereby minimizing skeletal muscle damage and fatigue and promoting recovery [ 19 ].
Studies suggest that the use of large doses of antioxidant supplements, especially vitamins C and E, may actually reduce rather than promote some of the beneficial effects of exercise.
One study, for example, randomly assigned 54 healthy Norwegian men and women age 20—30 years, most of whom were recreational exercisers, to receive 1, mg vitamin C and mg about IU vitamin E as DL-alpha-tocopherol or a placebo daily for 11 weeks while engaging in an endurance training program consisting mostly of running.
Compared with placebo, the supplements had no effect on maximal oxygen consumption VO 2 max, a measure of aerobic fitness and endurance capacity or running performance. However, they significantly lowered levels of biochemical markers related to mitochondrial creation and exercise-induced cell signaling, thereby diminishing the desirable training-induced adaptations within skeletal muscle [ 20 ].
The same research group conducted another trial using the same doses of vitamins C and E in 32 young men and women who followed a strength-training program for 10 weeks.
Compared with placebo, the supplements did not affect muscle growth, but they significantly reduced the gain in arm strength as measured by biceps curls and blunted cellular signaling pathways linked to muscle hypertrophy [ 21 ]. After 7 days of high-intensity cycling sprints, the CoQ 10 group had, on average, a significantly smaller improvement in mean power output than the placebo group, suggesting a poorer adaptation to training.
The preponderance of research to date suggests that exercise-induced reactive oxygen species and nitric oxide are beneficial. These free radicals induce adaptive changes in muscle that lead to greater production of mitochondria and hypertrophy of myofibers [ 17 , 21 , 23 , 24 ]. However, these adaptations might not prevent improvements in VO 2 max or endurance performance [ 25 ].
Studies on the safety of vitamins C, E, and other antioxidant supplements taken during exercise show no evidence of adverse effects, aside from potentially reducing some of the benefits of exercise, but such studies have only lasted a few weeks or months.
These amounts are substantially higher than the doses that studies have typically used for exercise and athletic performance. Among the potential adverse effects of excess vitamin C are diarrhea, nausea, abdominal cramps, and other gastrointestinal disturbances.
The intake of excessive amounts of vitamin E increases the risks of hemorrhagic effects. The side effects of CoQ 10 are mild and can include fatigue, insomnia, rashes, nausea, upper abdominal pain, heartburn, sensitivity to light, irritability, dizziness, and headaches [ 28 ]. Little research supports the use as ergogenic aids of antioxidant supplements containing greater amounts than those available from a nutritionally adequate diet [ 19 , 25 ].
In fact, they can adversely affect some measures of exercise and athletic performance. The Australian Institute of Sport, part of the government of Australia, does not recommend supplementation with vitamins C and E by athletes, except when they use these products as part of a research protocol or with proper monitoring [ 29 ].
More information on vitamin C and vitamin E is available in the Office of Dietary Supplements ODS health professional fact sheets on these nutrients. L-arginine is an amino acid found in many protein-containing foods, especially animal products and nuts. The body also synthesizes arginine from citrulline , mainly in the kidneys.
Some experts suggest that taking arginine in supplement form enhances exercise and athletic performance in several ways [ ]. First, some arginine is converted to nitric oxide, a potent vasodilator that can increase blood flow and the delivery of oxygen and nutrients to skeletal muscle.
Second, increased vasodilation can speed up the removal of metabolic waste products related to muscle fatigue, such as lactate and ammonia, that the body produces during exercise. Third, arginine serves as a precursor for the synthesis of creatine, which helps supply muscle with energy for short-term, intense activity.
Fourth, arginine may increase the secretion of human growth hormone HGH , which in turn increases insulin-like growth factor-1 IGF-1 levels, both of which stimulate muscle growth. The research to support supplemental arginine as a performance enhancer is limited and conflicting.
Furthermore, arginine typically had no effect on nitric oxide concentration, blood flow, or exercise metabolites e. A recent review assessed 54 clinical studies examining the effects of arginine supplementation on strength performance, endurance, muscle blood volume and flow, cardiorespiratory measures, and nitric oxide production in healthy, active adults.
The authors concluded that supplemental arginine either alone or, more commonly, in combination with other ingredients, such as branched-chain amino acids [BCAAs] and lysine provided little or no enhancement of athletic performance and did not improve recovery from exhaustion [ 33 ].
Most of the studies included few participants, primarily young men age 18—25 years only four studies included women , and lasted only 4—8 weeks with none lasting 3 months or longer. Research on the ability of supplemental arginine to raise HGH and IGF-1 serum concentrations also has had conflicting findings.
Even raised HGH secretion, however, might not translate into more blood flow into muscle or greater protein synthesis [ 31 ]. Little evidence shows supplemental arginine by itself increases muscle creatine concentrations or is superior or complementary to direct consumption of creatine [ 30 ].
The safety of taking high-dose arginine supplements for more than 3 months is not known [ 33 ]. Beets are one of the richest food sources of inorganic nitrate.
Ingested nitrate might enhance exercise and athletic performance in several ways, primarily through its conversion into nitric oxide in the body.
Nitric acid is a potent vasodilator that can increase blood flow and the delivery of oxygen and nutrients to skeletal muscle.
Ingested nitrate might also enhance performance by dilating blood vessels in exercising muscle when oxygen levels decline, thereby increasing oxygen and nutrient delivery, reducing the oxygen cost of submaximal exercise, attenuating the adenosine triphosphate ATP -creatine phosphate energy system's cost associated with skeletal muscle force production, and improving oxidative phosphorylation in mitochondria [ 40 , 41 ].
Beetroot is available as a juice or juice concentrate and in powdered form; the amount of nitrate can vary considerably among products. A growing number of clinical trials investigating beetroot juice or concentrate as an ergogenic aid have been published since Beetroot has generally improved performance and endurance to different extents compared with placebo among runners, swimmers, rowers, and cyclists in time trials and time-to-exhaustion tests, but not in all studies [ 40 , ].
Performance benefits are more likely in recreationally active nonathletes than elite athletes [ 42 , 46 ]. One study in 10 recreationally active, young male cyclists suggested a dose-response relationship [ 47 ].
Although consuming beetroot juice concentrate on each of 4 days to supply 4. However, consumption of even more beetroot juice supplying There has been little study of the effects of beetroot on anaerobic performance, such as high-volume resistance exercise with many repetitions [ 40 ].
More research is needed to clarify the potential benefits of nitrate supplementation from beetroot juice on exercise and athletic performance and to determine the best doses and dosing protocols [ 48 ].
No research has assessed longer term supplementation with beetroot-derived nitrate beyond several weeks as an ergogenic aid. The amount of nitrate that this amount of juice provides is less than half the total nitrate consumption from a diet rich in vegetables and fruits [ 49 ].
Although not a safety concern, beetroot consumption can color the urine pink or red due to the excretion of red pigments in the beets [ 50 ]. In a position statement, the Academy of Nutrition and Dietetics AND , the Dietitians of Canada DoC , and the American College of Sports Medicine ACSM state that nitrate sources, such as beetroot juice, enhance exercise tolerance and economy and they improve endurance exercise performance in recreational athletes [ 12 ].
The Australian Institute of Sport supports the use of beetroot juice for improving sports performance in suitable athletic competitions under the direction of an expert in sports medicine, but it notes that more research might be required to understand how the supplement should be used for best results [ 29 ].
This amount of juice provides about 5—11 mmol or — mg nitrate, depending on the product [ 41 ]. Potential benefits persist for up to 24 hours after ingestion [ 40 ]. The labels on beetroot juice and concentrate usually indicate that these products are foods and not dietary supplements.
Some dietary supplements contain beetroot powder in varying amounts, but studies have not assessed whether these are viable alternatives to beetroot juice or beetroot-juice concentrate.
Beta-alanine, a type of amino acid that the body does not incorporate into proteins, is the rate-limiting precursor to the synthesis of carnosine—a dipeptide of histidine and beta-alanine—in skeletal muscle. Carnosine helps buffer changes in muscle pH from the anaerobic glycolysis that provides energy during high-intensity exercise but results in the buildup of hydrogen ions as lactic acid accumulates and dissociates to form lactate, leading to reduced force and to fatigue [ 51 ].
More carnosine in muscle leads to greater potential attenuation of exercise-induced reductions in pH, which could enhance performance of intense activities of short to moderate duration, such as rowing and swimming [ 52 ].
Beta-alanine is produced in the liver, and relatively small amounts are present in animal-based foods such as meat, poultry, and fish. Carnosine is present in animal-based foods, such as beef and pork.
However, oral consumption of carnosine is an inefficient method of increasing muscle carnosine concentrations because the dipeptide is digested into its constituent amino acids.
Consumption of beta-alanine, in contrast, reliably increases the amount of carnosine in the body. For example, in one study of young, physically active but untrained adult men who took 4. Among the low responders, the duration of the washout period when beta alanine concentrations returned to baseline values was less than half that for the high responders 6 weeks vs.
Studies have evaluated beta-alanine as a potential ergogenic aid with a variety of participants, exercise and activity protocols, and dosing regimens. Some studies suggest that beta-alanine consumption could provide small performance benefits in competitive events requiring high-intensity effort over a short period, such as rowing, swimming, and team sports e.
Other studies have found no such benefits [ 53 ]. Evidence is conflicting on whether beta-alanine consumption improves performance in endurance activities, such as cycling [ 53 , 56 ]. Experts have not reached consensus on whether beta-alanine consumption primarily benefits trained athletes or recreationally active individuals [ 53 , 57 ].
Studies provide little consistent evidence of a relationship between the dose of beta-alanine and performance effect [ 51 , 58 ]. The authors of a Department of Defense-sponsored review concluded that the limited evidence from 20 human trials did not support consumption of beta-alanine alone or in combination products by active adults to enhance athletic performance or improve recovery from exercise-related exhaustion [ 59 ].
Most of the studies in this review included young men age 18—25 years who took 1. However, performance benefits are more modest in exercise tests lasting more than 4 minutes because aerobic metabolic pathways increasingly meet energy demands.
The ISSN called for more research to determine whether beta-alanine increases the strength and muscle mass that regular resistance exercise, such as weightlifting, can produce.
The authors of the most recent review of studies on beta-alanine's effects on exercise concluded that supplementation has a statistically significant and positive effect on performance including in both isolated-limb and whole-body exercises , especially in protocols lasting 30 seconds to 10 minutes [ 58 ].
However, this review also highlighted the fact that small studies of short duration using varied exercise and supplement protocols dominate this scientific literature. The 40 placebo-controlled studies reviewed, for example, employed 65 exercise protocols and 70 exercise measures in a total of 1, participants.
Furthermore, the total dose of beta-alanine that participants consumed ranged from 84 to g in studies lasting 28—90 days. Beta-alanine supplementation appears to be safe at 1. This tingling, prickling, or burning sensation is common in the face, neck, back of the hands, and upper trunk and typically lasts 60—90 minutes but is not a painful, serious, or harmful reaction.
Use of divided doses or a sustained-release form of the supplement can attenuate paresthesia resulting from beta-alanine consumption [ 52 , 54 ].
Some research has also found that beta-alanine supplements can produce pruritus itchy skin , but the authors do not indicate the severity of this effect [ 59 ]. There are no safety data on use of the supplement for more than 1 year [ 54 , 60 ].
There is insufficient expert consensus on the value of taking beta-alanine to enhance performance in intense, short-term activities or its safety, particularly when users take it regularly for at least several months. In a position statement, the AND, DoC, and ACSM advise that beta-alanine supplementation might improve training capacity and does enhance performance, especially of high-intensity exercise lasting 60— seconds, that acid-base disturbances resulting from increased anaerobic glycolysis would otherwise impair [ 12 ].
In its position statement, the ISSN concludes that beta-alanine supplementation improves exercise performance and attenuates neuromuscular fatigue [ 54 ]. The Australian Institute of Sport supports the use of beta-alanine for improving sports performance in suitable athletic competitions under the direction of an expert in sports medicine, but it notes that more research might be required to understand how the supplement should be used for best results [ 29 ].
It advises users to take beta-alanine supplements with meals to augment muscle carnosine levels and to use divided lower doses or take a sustained-release form if paresthesia occurs. HMB is a metabolite of the branched-chain amino acid leucine. Some experts hypothesize that skeletal muscle cells that become stressed and damaged from exercise require an exogenous source of the coenzyme for synthesis of cholesterol in their cellular membranes to restore structure and function [ 62 , 63 ].
Experts also believe that the conversion of leucine to HMB activates muscle protein synthesis and reduces protein breakdown [ 63 ].
Although studies have investigated HMB for two decades, they have used substantially different periods of supplementation 1 day to 6 weeks and daily doses 1.
Studies also used participants of different ages 19 to 50 years , training status e. It is therefore difficult to predict what, if any, benefits an exercising individual might experience from consuming HMB.
There is general agreement that HMB helps speed up recovery from exercise of sufficient amount and intensity to induce skeletal muscle damage [ 63 , 65 ]. Therefore, trained athletes must exert themselves more than untrained individuals to potentially benefit from using the supplement.
Some studies suggest that HMB use has additional benefits, including an ability to enhance strength, power, skeletal muscle hypertrophy, and aerobic performance in both trained and untrained people [ 63 ].
A review of safety data from nine studies found that users tolerate HMB well, and it is safe at daily intakes of 3 g for 3 to 8 weeks in younger ages 18—47 years and older ages 62—81 adults of both sexes who do or do not exercise [ 66 ].
Assessments of blood chemistry, hematology, and emotional affect found no adverse effects. Use of HMB did not alter or adversely affect any measured hematologic, hepatic, or renal-function parameters in these young men.
There is no expert consensus on the value of taking HMB for several months or longer or its safety. HMB is not on a list of evidence-based ergogenic aids issued by the AND, DoC, and the ACSM [ 12 ].
The Australian Institute of Sport does not recommend HMB supplementation by athletes, except as part of a research protocol or with proper monitoring [ 29 ]. However, the ISSN notes that HMB can enhance recovery by reducing exercise-induced skeletal muscle damage in both trained and untrained individuals [ 63 ].
HMB is available in two forms: as a mono-hydrated calcium salt HMB-Ca and a calcium-free form HMB-free acid [HMB-FA]. Those who wish to limit their calcium intake can use HMB-FA [ 63 ]. Although the latter form appears to have a faster and greater effect based on its ability to raise HMB plasma levels, more studies are needed to compare the effects of HMB-Ca with those of HMB-FA [ 63 ].
The ISSN recommends that healthy adults interested in using HMB supplements take 1—2 g HMB-Ca 60 to minutes before exercise or 1—2 g HMB-FA 30 to 60 minutes before exercise [ 63 ]. Betaine, also known as trimethylglycine, is found in foods such as beets, spinach, and whole-grain breads.
The mechanisms by which betaine might enhance exercise and athletic performance are not known, but many are hypothesized. A limited number of small studies in men have assessed betaine in supplemental form as a potential ergogenic aid. These studies, which typically examined strength- and power-based performance in bodybuilders and, occasionally, cyclists, provided conflicting results, and performance improvements tended to be modest [ ].
The several small studies of athletes described in the previous paragraph who took betaine supplements for up to several weeks found no side effects or safety concerns. However, research has not adequately evaluated the safety of betaine.
More research on betaine supplementation to enhance various types of performance, training protocols, and exercise during specific sports is needed before any recommendations for its use can be made [ 71 ]. Three essential amino acids EAAs —leucine, isoleucine, and valine—are the branched-chain amino acids BCAAs , whose name reflects their chemical structure.
Unlike other EAAs, the BCAAs can be metabolized by mitochondria in skeletal muscle to provide energy during exercise [ 74 , 75 ].
The BCAAs, especially leucine, might also stimulate protein synthesis in exercised muscle [ 72 , 76 ]. The limited research on the potential ergogenic effects of the BCAAs has found little evidence to date that supplements of these amino acids improve performance in endurance-related aerobic events [ 75 ].
The BCAAs might delay feelings of fatigue or help maintain mental focus by competing with the amino acid tryptophan a precursor of the neurotransmitter serotonin that regulates mood and sleep for entry into the brain, but this effect has not been well studied [ 72 , 74 , 75 ].
Overall, however, studies to date provide inconsistent evidence of the ability of BCAAs to stimulate muscle protein synthesis beyond the capacity of sufficient dietary amounts of any high-quality protein to perform this function [ 76 ]. Furthermore, it is not clear from existing research whether consumption of protein and BCAAs before versus after a workout affects their ability to maximize muscle protein synthesis and reduce protein catabolism [ 12 , ].
Studies have not consistently shown that taking supplements of BCAAs or any of their three constituent amino acids singly enhances exercise and athletic performance, builds muscle mass, or aids in recovery from exercise.
Consuming animal foods containing complete proteins—or a combination of plant-based foods with complementary proteins that together provide all EAAs—automatically increases consumption of BCAAs see section on protein.
This is also true of consuming protein powders made from complete proteins, especially whey, which has more leucine than either casein or soy [ 78 ].
Caffeine stimulates the central nervous system, muscles, and other organs such as the heart by binding to adenosine receptors on cells, thereby blocking the activity of adenosine, a neuromodulator with sedative-like properties [ 83 , 84 ].
In this way, caffeine enhances arousal, increases vigor, and reduces fatigue [ 13 , 85 , 86 ]. Caffeine also appears to reduce perceived pain and exertion [ 13 , 85 ]. During the early stages of endurance exercise, caffeine might mobilize free fatty acids as a source of energy and spare muscle glycogen [ 38 ].
Caffeine is commonly used in energy drinks and shots touted for their performance-enhancement effects [ 87 , 88 ]. It is also found in energy gels containing carbohydrates and electrolytes as well as in anhydrous caffeine-only pills.
For an individual weighing pounds 70 kg , this dose is equivalent to — mg caffeine. Taking more, however, is unlikely to improve performance further and increases the risk of side effects. A review of the literature found that caffeine intake affected sport-specific performance e.
The Athletic performance Ayhletic good Athletic performance and good nutrition is Athletic performance established. Interest in Herbal remedies for memory enhancement and its impact on sporting performance Atnletic now a science in itself. Whether you are a competing athlete, a weekend sports player or a pefformance daily exerciser, the foundation to Athletic performance performance is performamce nutritionally adequate diet. Athletes who exercise strenuously for more than 60 to 90 minutes every day may need to increase the amount of energy they consume, particularly from carbohydrate sources. The current recommendations for fat intake are for most athletes to follow similar recommendations to those given for the general community, with the preference for fats coming from olive oils, avocado, nuts and seeds. Athletes should also aim to minimise intake of high-fat foods such as biscuits, cakes, pastries, chips and fried foods. After absorption, glucose can be converted into glycogen and stored in the liver and muscle tissue.
