Table 4.

Partial correlations controlling for sex between body composition (body mass index [BMI], body fat percentage [BF%], waist circumference [WC], and waist-to-hip ratio [WHR]) and fitness test performance (sit-and-reach, combined grip strength one-repetition maximum [1 RM] leg press, crunches, push-ups, and estimated maximal aerobic capacity [V̇O2max]) in male and female firefighters (N = 270).
