Many health clubs and personal trainers test clients to evaluate their fitness, prescribe training programs and evaluate the effects of an exercise program to see if there has been progress. Thus, testing is an important part of their service.

There are presently no established national standards or laws about qualifications to be a personal trainer. As a result, people who work in health and fitness clubs have a wide variety of educational and professional backgrounds. There are "personal trainers" with no formal courses in physical education, exercise science or other related university degrees. If they want to be a certified personal trainer, there are online, mail-order certificates that require only payment to obtain a certificate to put on the wall. Some of these "certifying agencies" do not require an examination to test the knowledge of the applicants.

Energy drinks (EDs) contain caffeine and are a new, popular category of beverage. It has been suggested that EDs enhance physical and cognitive performance; however, it is unclear whether the claimed benefits are attributable to components other than caffeine. A typical 235 mL ED provides between 40 and 250 mg of caffeine, equating to doses that improve cognitive and, at the higher levels, physical performance. EDs often contain taurine, guaranĂ¡, ginseng, glucuronolactone, B-vitamins, and other compounds. A literature search using PubMed, Psych Info, and Google Scholar identified 32 articles that examined the effects of ED ingredients alone and/or in combination with caffeine on physical or cognitive performance.
