Gender Differences in Load-Velocity Profile of the Squat and Deadlift in Soccer Players
Keywords:
velocity-based training; sex differences; 1RM; rate of force developmentAbstract
This study aimed to explore the differences in the load-velocity profile between deadlift and squat exercises in men and women. The load-velocity profiles (from 30% to 100% of the one-repetition maximum [1RM] in 5% increments) of 42 soccer players (25 men and 17 women) were tested during deadlift and squat. Relationship between mean propulsive velocity and %1RM were analyzed. ANOVA test was applied to compare each dependent variable (i.e., mean velocity values attained at each %1RM and mean test velocity), with sex (men and women). Close relationships between bar velocity and relative load were observed for both sexes for squat (R2 = 0.76-0.95) and deadlift (R2 = 0.86-0.88). Moreover, men showed statistically higher mean propulsive velocity than women (p < 0.001–0.05) in squat and deadlift. These results confirm that men present higher velocities at moderate to high relative loads (i.e., %1RM) compared to women during lower-body exercises.
