Substance Abuse and Rehabilitation. Regulatory Toxicology and Pharmacology. Clinics in Sports Medicine. In , Chandler and Blair 47 showed significant increases in knee extension strength, acceleration, anaerobic capacity, time to exhaustion during exercise, pre-exercise and maximum heart rates, and time to exhaustion during maximal oxygen consumption VO2 max testing after administration of 15 mg of dextroamphetamine versus placebo.

Most of the information to answer this question has been obtained in the past decade through studies of fatigue rather than an attempt to systematically investigate the effect of ADHD drugs on exercise.

In , Roelands and colleagues 53 studied the effect of reboxetine, a pure NE reuptake inhibitor, similar to atomoxetine, in 9 healthy, well-trained cyclists. They too exercised in both temperate and warm environments.

They showed decreased power output and exercise performance at both 18 and 30 degrees centigrade. Their conclusion was that DA reuptake inhibition was the cause of the increased exercise performance seen with drugs that affect both DA and NE MPH, amphetamine, and bupropion.

Frontiers in Integrative Neuroscience. Manipulations of dopaminergic signaling profoundly influence interval timing, leading to the hypothesis that dopamine influences internal pacemaker, or "clock," activity. For instance, amphetamine, which increases concentrations of dopamine at the synaptic cleft advances the start of responding during interval timing, whereas antagonists of D2 type dopamine receptors typically slow timing; Depletion of dopamine in healthy volunteers impairs timing, while amphetamine releases synaptic dopamine and speeds up timing.

Sports Medicine. S2CID Frontiers in Physiology. Aside from accounting for the reduced performance of mentally fatigued participants, this model rationalizes the reduced RPE and hence improved cycling time trial performance of athletes using a glucose mouthwash Chambers et al.

Dopamine stimulating drugs are known to enhance aspects of exercise performance Roelands et al. Sports Medicine Auckland, N. ISSN X. World Anti-Doping Agency.

In recent decennia however, it became clear that the central nervous system plays an important role in the onset of fatigue during prolonged exercise Klass et al. This indicates that subjects did not feel they were producing more power and consequently more heat.

The authors concluded that the "safety switch" or the mechanisms existing in the body to prevent harmful effects are overridden by the drug administration Roelands et al. Taken together, these data indicate strong ergogenic effects of an increased DA concentration in the brain, without any change in the perception of effort.

The combined effects of DA and NA on performance in the heat were studied by our research group on a number of occasions.

Coinciding with this ergogenic effect, the authors observed core temperatures that were much higher compared with the placebo situation. Interestingly, this occurred without any change in the subjective feelings of thermal sensation or perceived exertion.

Journal of Cognitive Neuroscience. The present meta-analysis was conducted to estimate the magnitude of the effects of methylphenidate and amphetamine on cognitive functions central to academic and occupational functioning, including inhibitory control, working memory, short-term episodic memory, and delayed episodic memory.

In addition, we examined the evidence for publication bias. Forty-eight studies total of 1, participants were included in the analyses. We found evidence for small but significant stimulant enhancement effects on inhibitory control and short-term episodic memory.

Small effects on working memory reached significance, based on one of our two analytical approaches. Effects on delayed episodic memory were medium in size.

However, because the effects on long-term and working memory were qualified by evidence for publication bias, we conclude that the effect of amphetamine and methylphenidate on the examined facets of healthy cognition is probably modest overall.

In some situations, a small advantage may be valuable, although it is also possible that healthy users resort to stimulants to enhance their energy and motivation more than their cognition.

Earlier research has failed to distinguish whether stimulants' effects are small or whether they are nonexistent Ilieva et al. The present findings supported generally small effects of amphetamine and methylphenidate on executive function and memory.

Specifically, in a set of experiments limited to high-quality designs, we found significant enhancement of several cognitive abilities. The results of this meta-analysis cannot address the important issues of individual differences in stimulant effects or the role of motivational enhancement in helping perform academic or occupational tasks.

However, they do confirm the reality of cognitive enhancing effects for normal healthy adults in general, while also indicating that these effects are modest in size. Whether you like to spend your weekends on the rugby field or trying to set PRs in the gym, current research supports the benefits of caffeine in sports and high-intensity intermittent exercise.

Because many fitness activities are played outdoors in the heat and humidity or in poorly ventilated gyms, maintaining proper hydration status is critical for optimal performance. If you're limited to water breaks, make sure to consume ounces of fluid hours prior to your activity, and another 8 ounces right before you start play.

After competition, begin rehydrating immediately, aiming to get in another ounces of fluids for every pound of bodyweight you lost via sweat. It's mile five of the Tough Mudder and you still have ditches to hurdle, ladders to climb, and walls to scale.

When pride and bragging rights between you and your buddies are at stake, you need all the help you can get! Enter beta-alanine. During high-intensity activity, your body accumulates hydrogen ions, causing a drop in your pH level, ultimately resulting in fatigue.

Beta-alanine supplementation has been shown to increase intramuscular carnosine content, thereby increasing the body's ability to buffer hydrogen ions and delay fatigue. Beta-alanine supplementation can help improve your exercise performance and training volume, which will ultimately help solidify your right to gloat for another year.

Physical activity puts stress on your body, and that stress increases the longer, harder, or more frequently you engage in fitness.

Recovery, then, becomes more critical as your training increases, and protein is essential for recovery. Keep in mind that protein is rarely used as an energy substrate i. However it's still essential for the repair, construction, and maintenance of muscle mass.

Consuming protein after a tough workout will not only increase protein synthesis rates, but will help you recover faster so that you're ready to dominate your next event! Fish oil is an excellent source of omega-3 fatty acids, which are key players in the recovery process.

Why do some bodybuilders and athletes take dietary supplements? What dietary supplements are banned by the NCAA? Are dietary supplements necessary? What is creatine? Is creatine safe? Do performance-enhancing dietary supplements work? Are bodybuilding supplements safe?

Dangerous hidden ingredients are an increasing problem in products promoted for bodybuilding, the U. Food and Drug Administration FDA warns. Consumers may unknowingly take products laced with prescription drug ingredients, controlled substances, and other ingredients. Bodybuilding supplements often are adulterated with anabolic steroids that are modified variants of male hormones designed to increase muscle mass.

Liver injury from taking bodybuilding dietary supplements has increased in recent years. Bodybuilding products are the most common cause of liver injury linked to herbal and dietary supplement use.

Products containing the stimulants BMPEA or DMAA can cause serious health problems. DMAA-containing products marketed as dietary supplements are illegal. In , the FDA began taking action to remove these products from the market.

However, DMAA is still found in some products marketed as supplements, including under different names, such as geranium oil. Some dietary supplements may interact with drugs or other supplements. Some vitamins and minerals are harmful at high doses.

Talk with your health care provider before using a dietary supplement for bodybuilding or endurance. For More Information.

Carnitine can also interact harmfully with some medications, such as thyroid medications and the blood thinner warfarin. Drugstores often sell the mineral as chromium picolinate. Muscles use creatine to release energy, which enhances lean muscle mass and increases muscle energy.

Those who take creatine often do so as a means to build muscle mass. Taking creatine is also not without its side effects. For example, creatine can cause weight gain, muscle cramping, and stomach cramping.

Additionally, the liver and kidneys must filter creatine. Taking an excessive amount can put a strain on these important organs, which could potentially damage them.

Individual results may vary for all of these supplements. Talk with your doctor or athletic trainer about the safety and effectiveness of individual supplements. The NCAA and the Olympics commission have banned some substances because they offer an unfair advantage or can cause harm to the athlete.

Anabolic and other steroids are illegal in sporting events and according to the law. The side effects are numerous and potentially fatal. Examples include androstenedione, stanozolol, axiron, and fortesta.

DHEA is possibly the most abundant steroid in humans. Using synthetic versions to increase steroid production is potentially dangerous. Diuretics are medications that cause a person to urinate more frequently. Diuretics can cause a variety of harmful side effects, such as cramping, dizziness, blood pressure drops, and electrolyte imbalances.

Blood doping is the process of boosting red blood cells to help carry more oxygen to the muscles and lungs.

It can be done through a blood transfusion or through use of drugs like erythropoietin. Athletes use the medication to make more red blood cells in their bodies. Endurance athletes may especially try to use erythropoietin, believing they they can perform longer with more oxygen.

Ephedrine is a central nervous stimulant. Ephedrine produces similar effects to adrenaline, but it too can be dangerous.

It can cause serious cardiovascular effects, including stroke, and a whole host of other problems. Both athletic organizations and the FDA have banned it. HGH is a drug developed to help treat growth disorders in children.

It stimulates cell reproduction and regeneration. Athletes looking to gain an edge may misuse this drug to achieve it. Potential complications include enlarged organs and chronic disease.

They can cause more damage than stripping an athlete of a title. Training, dedication, hydrating fluids, and proper diet are safer options and better than any ergogenic aids for boosting performance. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

Learn what anabolic steroids are, what they're used for both legally and illegally , and how to find safe alternatives that'll give you the same….

There are several dietary supplements that can help increase muscle mass and strength. Low iron levels are associated with decreases in athletic performance, but high doses of iron, or of any other vitamin or mineral, have not been shown to improve sports performance in otherwise healthy athletes.

Anabolic steroids are drugs that are illegal without a doctor's prescription. Athletes sometimes use anabolic steroids to enhance muscle strength and size. Nonathletes may use anabolic steroids because they want to look more muscular. However, there are side effects. Anabolic steroids stop growth in children and teens who are still gaining height.

They may also cause long-term problems with the heart, skin, and other organs that can be severe and may be irreversible. Note: Anti-inflammatory steroids, such as prednisone, that are used for asthma and other conditions are safe and often needed for young athletes when prescribed by a doctor.

Eat carbohydrates. Athletes should consume carbohydrate-rich foods every several hours on the day of competition. Carbohydrates are an important source of fuel during exercise. Stay hydrated. Sports performance can be enhanced when athletes get the right amount of fluid and electrolytes.

Proper hydration is especially important during practices or games that last more than 60 minutes. Here are a few guidelines to keep the body hydrated and performing at its best level.

During practice and competition: Drink 4 to 8 ounces of water or sports drinks every 15 minutes throughout the practice or competition.

Athletes should reload their bodies with fluids and food as soon as possible after a practice or game. Reloading is especially important when athletes are playing in multiple games in a short time frame, such as during a basketball or soccer tournament. Eat well.

A well-balanced meal with the right kinds of proteins and carbohydrates will help the muscles recover between practices and games. Well-balanced meals are especially important if athletes are recovering from an injury and want to return to practice and competition.

Established Performance Supplements There is robust evidence that the following supplements can enhance sports performance when used according to established protocols.

Caffeine Caffeine, a stimulant that is ubiquitously consumed in the diets of most adults, has well-established benefits for athletic performance. Endurance performance Caffeine supplementation is known to improve endurance capacity during time to fatigue exercise tasks—for instance, during activities such as treadmill running to exhaustion French et al.

Short-term, supramaximal, and repeated sprint tasks The effects of caffeine on short-term, supramaximal, and repeated sprint tasks have been less well studied. Creatine Creatine is another widely-researched supplement, with creatine monohydrate CM being the most common form used to supplement dietary intake from meats.

Nitrate Dietary nitrate NO 3 — is a popular supplement initially found to improve oxygen uptake VO 2 kinetics during prolonged submaximal exercise Bailey et al. Beta-Alanine 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.

Sodium Bicarbonate 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.

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

Phosphates Numerous hypotheses have been proposed to support the potential benefits of phosphate supplementation on athletic performance see Buck et al. Developing Performance Supplements This section covers supplements which are emerging in both their popularity and the evidence base for athletic performance benefits.

Concluding Remarks This review summarizes the evidence for a number of commonly-used supplements, ingested with the aim of enhancing athletic performance. PubMed Brewer , C. PubMed false. PubMed Burke , L. PubMed Gomez-Cabrera , M.
