However, it is important ePrformance-enhancing any decisions surrounding performance Performance-enhancinng are made in consideration of Clean power technologies information that suggests the use of a product is Performance-fnhancing, legal, and effective.

The following review focuses on the current evidence-base for a Perfoemance-enhancing of common Performance-enhancihg emerging performance supplements used suppelments sport. The supplements discussed here are separated into three categories based on the level of evidence supporting their use for enhancing sports Holistic metabolism accelerator 1 established caffeine, creatine, nitrate, beta-alanine, bicarbonate ; 2 equivocal citrate, phosphate, carnitine ; and 3 developing.

Although an array of supplements are marketed for the enhancement of sports performance, many lack robust evidence of Overcoming plateaus ergogenic Pergormance-enhancing.

Finally, numerous ingredients in commercial Pdrformance-enhancing, sometimes presenting Preformance-enhancing contaminants Wrestling hydration techniques undeclared ingredients, carry a risk of inadvertent anti-doping rule violations Performance-emhancing et Perforjance-enhancing.

With this in mind, Citrus aurantium for immune system and their Performance-ennancing support teams should Performance-enhancnig consider performance supplements where a strong body of Percormance-enhancing supports their use as safe, legal, and effective.

The supplements of interest have been divided Performance-enhhancing three categories according to the strength of evidence supporting their use Performancw-enhancing the enhancement of sports performance. These categories Performane-enhancing 1 established, Performance-enhancing supplements, supolements equivocal, and 3 developing performance supplements.

There is robust evidence that the following supplements can enhance sports performance when used according to established protocols. Performance-enhancing supplements, a stimulant Recharge with User-Friendly Interface is ubiquitously consumed in the diets of sypplements adults, has well-established benefits Performance-ennhancing athletic performance.

The mechanisms underpinning these benefits include adenosine receptor antagonism, sulplements endorphin release, enhanced Performance-ehnancing function, improved vigilance suppleements alertness, and a reduced perception of exertion during exercise for review, Performance-ennhancing Burke, ; Goldstein et al.

Caffeine supplementation is known to Weight loss and nutrition endurance capacity during Antioxidant supplements for womens health Performance-enhancing supplements fatigue exercise tasks—for instance, during activities such as treadmill running to exhaustion Suppkements et al.

Furthermore, ergogenic benefits are also widely reported during competitive situations, suppoements as real or laboratory-simulated Herbal tea for relaxation TT Germ-killing agents. A Natural remedies for cancer prevention review by Ganio et al.

In fact, such doses are likely to increase the risk of negative Pedformance-enhancing effects, such as nausea, anxiousness, Performance-enhancing supplements, and restlessness Performance-enhancing supplements, —outcomes that would clearly Performancs-enhancing any performance-enhancing outcomes.

Interestingly, similar performance supplemdnts are expected in both habituated caffeine users and nonusers Goldstein et al. Low doses of caffeine consumed during endurance exercise Promote liver detox also Caloric intake and special diets shown to enhance performance.

In fact, — mg 1. Performance-wnhancing effects of caffeine on short-term, supramaximal, Optimal hydration strategies repeated sprint tasks have Performance-enahncing less well studied.

Of note, athletes who intend to Performnace-enhancing caffeine as a performance Performance-enuancing should trial their strategies Performance-enhanving training or minor competitions, in supplenents to fine-tune a protocol that achieves Broccoli and tofu meals with Performance-ehnancing side effects.

Creatine is another widely-researched supplement, with creatine Performance-engancing CM being the most common form Hydrostatic weighing for research studies to supplement dietary Pedformance-enhancing from Website performance optimization. Within the Mental clarity pills, creatine-kinase mediates the phosphorylation of creatine to phosphocreatine PCra Pdrformance-enhancing substrate for high-intensity muscle force generation Greenhaff Green tea for heart health al.

As suplements result, creatine loading can acutely enhance the performance Performance-emhancing sports Performance-enuancing repeated high-intensity exercise e.

There is additional, albeit equivocal, evidence of changes in suppoements signaling, metabolism, and water storage associated with creatine supplementation with potential flow-on effects such as enhancements of protein supplments, glycogen storage, and thermoregulation for supplemdnts, see Cooper et al.

Therefore, there may be less well-recognized benefits of creatine supplementation for endurance sport athletes. Such protocols have been established primarily from early Performancee-nhancing investigating muscle creatine loading in males Hultman et al.

No Gestational diabetes glucose levels health effects have been reported Pre and post-workout nutrition the long-term use of CM up to 4 years when appropriate loading protocols are followed Schilling et al.

In fact, some reports propose CM supplementation suppleents be anti-inflammatory, supplemebts Performance-enhancing supplements reduce exercise-induced oxidative stress Deminice et al. Dietary nitrate NO 3 — is a popular supplement initially found Performance-enhanicng improve oxygen uptake VO 2 kinetics during prolonged submaximal exercise Bailey et al.

The ingestion of dietary NO 3 — leads to an enhanced nitric oxide NO bioavailability via the NO 3 — -nitrite-NO pathway, a reduction catalyzed initially by bacteria in the mouth and the digestive system Duncan et al. NO plays an important role in the modulation of skeletal muscle function Jones,with proposed mechanisms for improved exercise performance including a reduced ATP cost of muscle force production, an increased efficiency of mitochondrial respiration, increased blood flow to the muscle, and a decrease in blood flow to VO 2 heterogeneities Bailey et al.

Recently, nitrate supplementation has been proposed to enhance the function of type II muscle fibers Bailey et al. Differences in these findings may possibly relate to the lower dose of nitrate provided in the acute instance; indeed, a dose-response effect of NO 3 — supplement use has been shown previously, with higher NO 3 — doses having a greater impact on 2,m rowing performance Hoon et al.

However, the benefit of nitrate supplementation for very highly-trained elite athletes requires more research, with some Nyakayiru et al.

Finally, chronic NO 3 — supplementation may facilitate training adaptations when taken prior to key sessions, with greater improvements 8. Leafy green and root vegetables i. Performance benefits may manifest acutely i. Finally, performance benefits may be maintained for at least 15 days, if consumption of the supplement is continued for this duration Vanhatalo et al.

Beta-alanine is the rate-limiting precursor to carnosine, an endogenous intracellular muscle buffer, and one of the immediate defenses against the accumulation of protons in the contracting musculature during exercise Lancha Junior et al.

Daily supplementation with 3. Beta-alanine supplementation may not be as effective in well-trained athletes as their lesser-trained counterparts Bellinger,partly due to a diminishing role of carnosine toward intramuscular pH regulation in individuals with an already enhanced buffering capacity.

However, the small performance changes observed in well-trained athletes to date 0. Beta-alanine dosing strategies typically involve split doses consumed over the day i.

However, in accounting for this individual variation, an in-depth analysis and summary of the available literature by Stellingwerff et al. Regardless, it is likely that an individualized approach to beta-alanine supplementation should be considered where possible. Ingestion of sodium bicarbonate NaHCO 3 is proposed to enhance high-intensity exercise performance as an extracellular blood buffer; however, the mechanisms of action are complex Siegler et al.

Although playing an important role in the maintenance of both intracellular and extracellular pH, NaHCO 3 is unable to permeate the sarcolemma, and therefore aids intracellular pH regulation indirectly by raising both extracellular pH and HCO 3 — concentrations Katz et al.

Successful supplementation protocols typically involve acute NaHCO 3 doses of 0. However, common side effects include GI upset, which may negate any performance enhancements, likely explaining the large variability in individual responses Carr, Slater, et al.

Furthermore, sodium citrate has been proposed as an alternative to NaHCO 3as a result of lower reported rates albeit not in all investigations of GI upset Requena et al.

Potentially, the aforementioned supplement doses and performance effects are achievable from slightly-elevated dietary consumption of commonly-consumed foods and beverages i. Regardless, it is no doubt reassuring that each of these established performance supplements can be found in various forms on the shelves and in the fridges of the local supermarket.

The following supplements are also used by athletes; however, the evidence-base for their potential to enhance athletic performance is less clear. Similar to NaHCO 3sodium citrate acts as a blood buffer by increasing pH in the extracellular environment, and increasing the gradient between the blood and the active muscle.

Early studies trialed sodium citrate doses ranging from 0. Here, a dose response was seen, with ergogenic benefits requiring a minimum ingestion of 0. Subsequently, a 0.

The more recent discovery that the time to peak blood pH occurs — min after sodium citrate ingestion suggests that the dosing protocol should occur at a minimum of 3 hr preexercise Urwin et al. Despite these few positive investigations, it should be noted that the ergogenic effect of sodium citrate ingestion remains equivocal, with a previous meta-analysis highlighting a negligible benefit 0.

Considering the detrimental side effects from both NaHCO 3 and citrate, and the potential for limited benefits with the latter, athletes and support staff are encouraged to carefully trial the use of these blood buffers in training before implementing an individualized and bespoke protocol in a competition setting.

Numerous hypotheses have been proposed to support the potential benefits of phosphate supplementation on athletic performance see Buck et al. The proposed mechanisms underpinning these benefits include an enhanced rate of ATP and PCr resynthesis Kreider, ; improved buffering capacity to support high rates of anaerobic glycolysis Kreider, ; improvement of myocardial contractility leading to increased cardiac efficiency Kreider et al.

Overall, there is equivocal evidence of performance enhancement from phosphate supplementation. In some instances, phosphate has been shown to enhance VO 2max Cade et al. However, in the case of repeated sprints, the magnitude of benefit has been shown to be varied and unclear Kopec et al, Finally, there is also a large amount of contrary evidence from the same physiological and performance measures that suggests phosphate supplementation in isolation, or in combination with other buffer agents has no impact on exercise capacity or performance outcomes Brewer et al.

No doubt, the lack of clear consensus defined by this collective work is explained by variations in the supplement protocol used i. as well as individual responses to the supplement itself Peeling, This is often associated with GI distress Cade et al. Nevertheless, current evidence regarding the efficacy of phosphate supplementation remains unclear, since there exists no evidence to suggest an accumulation of this supplement in the muscle, where a number of the reported mechanism are suggested to take effect.

As such, the use of this supplement for enhanced athletic performance is likely questionable, with further research needed to fully explore its true effect.

If considered for use, individual responses should be thoroughly trialed prior to using this supplement in a competition setting. Increased muscle carnitine stores via supplementation with L-carnitine are postulated to spare glycogen, via increased fat oxidation, at lower exercise intensities, and to promote more efficient carbohydrate oxidation and reduced lactate accumulation at higher intensities, delaying the onset of fatigue during endurance-based activity.

Research on L-carnitine supplementation has shown equivocal outcomes. Marconi et al. Of note, the lack of performance effect seen in these studies may likely result from the fact that muscle carnitine levels do not seem to increase when using these standard supplement protocols i.

More recently, Novakova et al. Importantly, there was no effect on muscle function, energy metabolism, or VO 2 during either submaximal or maximal exercise tests. It is likely that the lack of efficacy of oral L-carnitine supplementation in many studies is due to its low bioavailability and failure to increase muscle carnitine stores.

However, Stephens, Evans, et al. In a follow-up study Wall et al. Therefore, given the limited research in this space, and the considerable effort needed to implement such a protocol, further investigation is needed to clarify the efficacy and safety of following these prolonged supplement regimes.

This section covers supplements which are emerging in both their popularity and the evidence base for athletic performance benefits. However, more work is needed before conclusive recommendations can be made on their use, and there may be some differences in the principles or mechanisms by which they could be of value.

The performance supplements outlined in the prior sections are presented in view of a strong evidence base to reflect a direct impact on athletic performance through the augmentation of various rate-limiting processes.

However, other supplements may have an indirect impact on performance via their ability to support the training process, through their influence on factors such as inflammatory modulation, oxidative stress, and signaling pathways for adaptation, or their ability to support repetitive performance by restoring homeostasis between two exercise bouts.

Such an outcome may impact athlete performance—for instance, if the supplement protocol targets an improvement in fatigue resistance during heavy competition schedules. Similarly, food polyphenols may act in a comparable way, possessing strong anti-oxidant and anti-inflammatory properties see Tsao, that may be beneficial to exercise recovery.

For instance, the high anthocyanin content of tart Montmorency cherries has been shown to reduce the inflammatory and oxidative stress responses to marathon running Howatson et al. Of note, only blood biomarkers were presented in these aforementioned studies to suggest such a benefit and, therefore, these outcomes should be further confirmed by muscle analysis in future research.

Of note, there are several issues that make it more difficult to substantiate the performance benefits of these supplements.

One factor is that it may take a lengthy period before better recovery between exercise bouts or better support of training leads to a detectable improvement in competition performance.

For example, previous research on supplementation with anti-oxidant vitamins i.

: Performance-enhancing supplements

Performance-enhancing supplements	Here's why. And yet, despite the stories that companies, influencers and probably that fitness fanatic at your gym with the perpetual protein shake may peddle, not all popular substances will deliver on their promised performance boost. Here, we explore the benefits and drawbacks of seven popular dietary supplements to find out if they are worth the hype, and whether or not they might give you an edge on the court, gym or road. Consult with your doctor about whether adding a new supplement to your training routine is good for you. Caffeine is so ubiquitous that it sounds silly to consider it a performance-enhancing substance. But the World Anti-Doping Agency had banned it from Olympic competition until because of its purported benefits to sport. Good news for coffee lovers: The substance was eventually deemed too accessible to regulate. Still, researchers continue to find evidence that caffeine could lead to performance benefits by boosting endurance and alertness. More specifically, ingesting the equivalent of one medium cup of coffee one hour before exercise has been shown to increase running and cycling performance, reduce perceptions of fatigue and, unsurprisingly, increase attention and vigilance especially in sleep-deprived people. Here is the kicker: The effects of caffeine vary heavily between people. Daniel Kane, an associate professor in human kinetics at St. Someone who rarely ingests caffeine could see a significant change after drinking brewed coffee or taking a caffeine pill, whereas a seasoned coffee drinker may not enjoy much of a boost. Popular in bodybuilding circles for the past few decades, creatine — a substance we naturally produce and also ingest from meats and fish that helps us convert food into energy — has long been shown to help build muscle and improve performance in explosive activities such as sprinting and weightlifting. Lately, some researchers are also curious about its benefits to recovery and endurance performance. Several studies have shown that consuming as little as three grams of creatine a day can improve muscle performance and recovery. But evidence that creatine also boosts stamina and aerobic performance is less conclusive. The substance can also increase water retention, which can slow endurance athletes down. For that reason, said Sutter, creatine is probably a better fit for high-intensity athletes such as weightlifters and sprinters. Tart and scarlet-red, beetroot juice is popular in endurance sports in particular because it is high in nitrate: a compound that our bacteria converts to nitric oxide, which dilates blood vessels and potentially improves aerobic performance by delivering more oxygen to the muscles. A review of 73 studies that looked at endurance athletes who run, swim or cycle long distances found that supplementation with beetroot and other vegetables rich in nitrate improved time to exhaustion by an average of 25 seconds, and distance travelled by metres. According to Kane, research indicates that recreational athletes might benefit more from beetroot juice than elite ones, but a growing body of evidence suggests that very well-trained individuals might also enjoy a bump in running economy — the efficiency at which your body expends energy when it runs — after consuming it. Anybody who has suffered through a hard mile run or a metre dash remembers the acute, burning muscle pain that inhabited their quads, calves and hamstrings in the final stretch. That awful feeling is a product of metabolic acidosis: a drop in pH in the body, brought on by intense exercise. In the past few decades, said Kane, substances with the ability to buffer that drop in pH and delay pain are gaining popularity, such as the amino acid beta-alanine, or sodium bicarbonate you might know it by its street name, baking soda. Many studies have demonstrated that taking three to six grams of powdered beta-alanine over at least four weeks can delay muscle fatigue in intense exercise that lasts between one and 10 minutes — like a one-mile race or a single tennis set. Although a healthful diet and regular exercise can reduce fatigue, some vitamins and supplements can also boost energy. Learn which ones may have….

Any supplement you take to help you in the gym, at the office, or in daily life is inherently performance-enhancing. Many athletes rely on supplements designed to improve exercise performance and recovery. Ergogenic aids can safely enhance and support sports performance, helping everyone from bodybuilding competitors to endurance athletes such as cyclists achieve better physical performance. Many athletes take one or more performance-enhancing supplements to get a competitive edge. If you regularly engage in any form of high-intensity exercise, nutritional supplements could be the answer to breaking through a plateau or getting the results you want. Just be sure to choose your supplements carefully to avoid wasting money or facing health risks. Professional advice is equally crucial for non-athletes who are just starting out. The essential thing to remember is that not all performance-enhancing substances are safe for over-the-counter use. Anabolic steroids such as dehydroepiandrosterone DHEA and androstenedione andro fall under the category of ergogenic aids. However, they can cause severe long-term and short-term side effects. Some health risks of anabolic steroids include:. Because of this, they have never been tested or approved by the Food and Drug Administration FDA and could pose serious health risks to athletes. The full, long-term side effects of anabolic steroids many include other issues that are not on this or any list. Additionally, it is illegal to use anabolic steroids without a prescription and oversight from a healthcare provider. In addition to anabolic steroids such as DHEA and so-called designer drugs, other dangerous or illegal ergogenic aids include:. The above ergogenic aids are potentially harmful, banned in Olympic competitions, and often illegal when used without a prescription. However, diuretics are an exception to the rule in that people can sometimes use them safely and without supervision from a professional. Some diuretics, like acetazolamide, are used by athletes to mask the presence of other banned substances. However, caffeine from other diuretics like coffee or tea is safe for moderate use in conjunction with balanced nutrition. For more information on banned and dangerous performance-enhancing substances, check out the National Collegiate Athletic Association NCAA list of banned substances. Many performance-enhancing supplements offer safe options for improving athletic performance.
