Fig 1. Body composition and physical activity.

Mean and standard deviations of body mass index (kg/m²), waist circumference and body fat percentage according to physical activity quintiles of total volume (MET-hours) in men (black bars) and women (gray bars). MET-hours ranges for the quintiles were: 19.92–33.22, 33.25–36.39, 36.39–38.87, 38.90–42.77 and 42.79–60.34, respectively. Inverse associations between volume and body composition measures, adjusted for age, smoking and educational attainment were statistically significant in both genders (P for trend < 0.001 for all).
