BACKGROUND: Health trends, which promote performance enhancement and maintaining or increasing muscle strength, may appeal to soldiers looking to maintain health standards set by the US Army, but often these trends require further investigation to assess safety and efficacy. High-intensity interval training (HIIT) and use of weight loss and/or performance-enhancing/body-building dietary supplements (WL/PES DS) are two such trends that, if implemented inappropriately, can negatively impact soldier health and readiness.
OBJECTIVE: Our aim was to establish health/psychosocial profiles of US Army soldiers who participate in HIIT and/or use WL/PES DS.
DESIGN: This cross-sectional observational study used data from the 2016 US Army Global Assessment Tool. PARTICIPANTS: Data were analyzed from respondents to the 2016 US Army Global Assessment Tool (n=299,996) who consented to have their data used for research purposes.
RESULTS: Soldiers were classified into four groups based on HIIT and/or WL/PES DS use. Thirty-five percent of soldiers participated in HIIT and 10% took WL/PES DS at least once per month in the last year. HIIT participation was associated with higher reported odds of healthy behaviors and higher emotional and social fitness. In contrast to HIIT, WL/PES DS use was associated with higher reported odds of risky behaviors (hazardous drinking and tobacco use) and lower psychosocial fitness. The group participating in HIIT but not using WL/PES DS reported fewer unhealthy behaviors compared to the HIIT+WL/PES DS and WL/PES DS-only groups.
CONCLUSIONS: Engaging in HIIT is associated with higher reported odds of healthy behaviors and increased psychosocial fitness. However, soldiers who engaged in HIIT also have increased odds of WL/PES DS use, which is associated with greater reported risky behaviors and reduced fitness. Although HIIT and WL/PES DS use are related, they are associated with different reported health/risky behaviors and different psychosocial attributes.
