Abstract:

Introduction: An ergogenic aid is any agent used to enhance energy production and/or utilization with the intent to improve performance in a particular sport or activity. Dietary supplements are consumed for their potential ergogenic effects by Soldiers seeking to improve physical performance. However, these agents are not regulated by the United States Food and DrugAdministration (FDA). The long-term health effects of these unregulated dietary supplements are unknown. The purpose of this study is to establish the incidence of dietary supplement use in a U.S. Army combat unit and to present a brief review of the literature on the documented adverse reactions related to dietary supplements use.

Methods: 750 Rangers from the U.S. Army 1st Ranger Battalion were administered an anonymous, self-reported, survey concerning recreational and competitive athletic participation, participation in weight training, ergogenic supplement use, and sources of nutritional information. All surveys were administered by the battalion surgeon. The data was analyzed using the Pearson’s Chi-square with continuity correction method of analysis.

Results: 294 Rangers (39.5%) completed the questionnaire. One hundred and nine (37%) of the responders admitted to using at least one dietary supplement. The average age of the respondent was 23 years. Dietary supplement use was associated with participation in recreational athletics and weight training. Protein supplements were the most common supplement, followed by creatine and thermogenics respectively. Less than 1% used anabolic steroids. The most commonly cited source for nutritional information concerning ergogenic supplements is another Soldier, followed closely by fitness magazines. Less than 10% cited the unit surgeon or local nutritionist. Conclusions: Dietary supplement use in the surveyed unit is similar to rates reported for other athletic organizations. As the long-term health effects are unknown, the decision to consume dietary supplements should be carefully deliberated. Unit surgeons are uniquely situated to advise these Soldiers.
