Phase angle (PhA) is derived from bioimpedance analysis (BIA) and is widely used as an indicator of cellular health, cell membrane integrity, and cell function. Lower-body power and fitness capacity are of paramount importance in success in several sports, including badminton. This study aimed to evaluate the relationship between PhA and lower-body power and fitness capacity in 22 junior badminton players (14 males, 8 females, 17.7±1.4 years old). Bioelectrical impedance was used to assess body fat (BF), muscle mass (MM) and PhA. Countermovement jump test and Yo-yo intermittent test level 2 were used to evaluate lower-body power and fitness capacity, respectively. Pearson correlation and multiple regressions considering the effect of BF, MM, and age were used for statistical analysis. PhA exhibited a positive relationship with lower-body power (β = 0.48; P < 0.02) and fitness capacity (β = 0.37; P < 0.04). However, these relationships lost significance after adjustment for the co-variables MM, BF, and age (p > 0.24). PhA is associated with lower-body power and fitness capacity in junior badminton players. However, these relationships are influenced by MM, BF, and age co-variables.
