Abstract The purpose of this study is to compare recreationally physically active females and males with regard spine, pelvis lower limb joints peak angles in each plane motion during a single leg squat (SLS). second aim investigate the relationship between kinematics SLS depth males. Fifty-eight healthy, young adults performed 5 repetitions right maximal while keeping their balance. Kinematic data were obtained using an optical capture system. At hip, greater adduction internal rotation observed than Females had more extended spines less outward bended knees throughout did men. In males, was significantly, positively correlated angle ankle (r = 0.60, p < 0.001), knee 0.87, hip 0.73, 0.001) 0.40, 0.02) sagittal plane. A positive significant correlation found 0.88, 0.53, 0.01) females. Males used different motor strategies at all levels kinematic chain SLS.
