Final answer:
A fitness professional's role regarding nutritional supplements involves being informed about regulations like the DSHEA of 1994, avoiding the distribution of supplements with unverified claims, and focusing on evidence-based nutrition advice instead of unproven supplement benefits.
Step-by-step explanation:
The role and responsibilities of a fitness professional concerning the sale and distribution of nutritional supplements are crucial and must adhere to the guidelines set out by the Dietary Supplement Health and Education Act (DSHEA) of 1994. This act altered the way dietary supplements are regulated, transferring the burden of ensuring safety from government to the manufacturer. Fitness professionals must be aware that supplements do not require FDA approval before being marketed, and the safety or effectiveness does not have to be substantiated unless a new dietary ingredient is added.
Because of this, fitness professionals have a duty to evaluate nutritional supplements cautiously. They should avoid promoting products with false or misleading health claims and should provide athletes and clients with reputable information on supplements. This is particularly important as mislabeling and incorrect health claims are rampant, with many supplements not undergoing rigorous testing or verification processes. The responsibility, therefore, falls upon fitness professionals to ensure they do not distribute harmful or banned substances that could lead to health issues or sanctions against the individual or institution.
Athletic trainers and fitness professionals should focus on overall nutrition and a healthful diet as vital components of athletic performance, rather than relying on supplements that may not have proven benefits. It has been shown, for instance, that amino acid supplementation does not confer a significant advantage over maintaining a healthy diet. The promotion of optimal health and athletic performance should be rooted in evidence-based practices and an understanding of the nutrients required for individual athletes' needs.
