FM: fat mass; FFM; fat-free mass; HS: handgrip strength; CF: cardiorespiratory fitness; SA: speed–agility; FM%: fat mass percent; SLJ: standing long jump. Data are shown as mean (standard deviation) and median (interquartile range). * Significant differences for p ≤ 0.05 in nonparametric variables; † Significant differences for p ≤ 0.05 in parametric variables.
