Study Notes

Ergogenic Aids: Separating Fact from Fiction

Ergogenic aids are substances, devices, or dietary supplements used to improve athletic performance, but most have no reliable scientific evidence to support their effectiveness.
Many athletes believe in the value of these aids, but the perceived benefits are often due to the placebo effect rather than actual physiological changes.

Dietary Supplements and Ergogenic Aids

Bee pollen, dried adrenal glands from cattle, seaweed, freeze-dried liver flakes, and ginseng are examples of dietary supplements used by athletes to gain a competitive edge.
However, most of these supplements have no scientific evidence to support their ergogenic effects or long-term safety.
Athletes should be skeptical of claims made for any substance until its effects and safety have been determined by independent researchers.

Effective Ergogenic Aids

Sufficient water and electrolytes, carbohydrates, and a balanced and varied diet consistent with MyPlate recommendations are effective ergogenic aids.
Meeting carbohydrate and fluid needs, along with overall nutrient needs, is the most important ergogenic aid for athletes.

Caffeine

Caffeine is the most widely used ergogenic aid worldwide.
Caffeine raises the level of fatty acids in blood, allowing exercising muscles to use more fat for energy.
Caffeine also enhances the ability of skeletal and heart muscles to contract and increases mental alertness.
Consuming 3-6 mg of caffeine per kg of body weight about 1 hour before exercise can benefit certain athletes.
High doses of caffeine can cause nervousness, shakiness, and sleep disturbances, and very high doses can be deadly.

Banned Substances

Ephedrine-containing supplements were banned by the FDA in 2004 due to serious and deadly side effects.
Anabolic steroids and growth hormone are banned by the NCAA and other athletic organizations due to serious side effects, including liver damage, cardiovascular disease, and reproductive problems.

Energy Drinks

Energy drinks often contain caffeine or other stimulants that provide a temporary energy boost.
These drinks also provide calories if sweetened with added sugars.
Energy drinks may cause elevated heart rate and blood pressure, increased risk of engaging in risky behaviors, and other side effects.

Important Reminders

Athletes should focus on improving their dietary habits, training routines, and sports techniques rather than relying on ergogenic aids.
Nutrient supplements should only be used to correct specific dietary deficiencies, such as preventing iron deficiency or boosting calcium intakes.
Athletes should always consult with healthcare professionals or registered dietitians before using any dietary supplements or ergogenic aids.
