The Personal Training Profession

• Governing bodies/credentialing agencies• ACSM, NSCA, ACE, NASM, AFAA

Position Statements• ACSM: specific to athletes “used with caution and only after careful

product evaluation for safety, efficacy, potency, and legality. A qualified sports Dietitian should be consulted.

• NSCA: must not prescribe, recommend or provide supplements that are illegal, prohibited or harmful to participants for any purpose including enhancing athletic performance, conditioning or physique. Only those substances that are lawful and have been scientifically proven to be beneficial, or at least not harmful, may be recommended or provided to participants by S& C professionals and only to individuals 18 and above.

• AFAA recommends fitness professionals should not sell, recommend, or provide DS unless it is justified by existing sound scientific and medical research (beyond manufacturer). Use of supplements should be monitored by a health care provider.

• ACE “it is outside the defined scope of practice of a fitness professional to recommend, prescribe, sell, or supply nutritional supplements to clients. Recommending supplements without possessing the requisite qualifications can place the client’s health at risk and possibly expose the fitness professional to disciplinary action and litigation.
