Caution against BMI for obesity assessment in collegiate athletes; leaves open whether position-specific metrics improve cardiometabolic risk prediction.
Cross-Sectional (n=85)
p-value: p=<.01
BMI alone overestimates obesity in strength-trained athletes, though a subset of collegiate football players (especially linemen) meet multiple criteria for true obesity.
Mathews et al. (2008) conducted a cross-sectional in Overweight and obesity (n=85). Offensive lineman position vs. Most other positions was evaluated on Body fat percentage (% BF) (p=<.01). Offensive linemen had significantly higher body fat percentages than most other positions (p < .01), and BMI overestimated overweight and obesity prevalence in 50.6% of players.
