Movement velocity as a measure of exercise intensity in three lower limb exercisesMovement strength velocity and intensity KEY WORDS: Resistance training, movement velocity, strength. ABSTRACTThe purpose of this study was to investigate the relationship between movement velocity and relative load in three lower limbs exercises commonly used to develop strength: Leg Press, Full Squat, and Half Squat. The percentage of one Repetition Maximum (%1RM) has typically been used as the main parameter to control resistance training, however more recent research has proposed movement velocity as an alternative.Fifteen participants performed a load progression with a range of loads until they reached their one repetition maximum (1RM). Maximum instantaneous velocity (Vmax) and mean propulsive velocity (MPV) of the knee extension phase of each exercise were assessed.For all exercises, a strong relationship between Vmax and the %1RM was found: Leg Press (r 2 adj =0.96; 95% CI for slope is [-0.0244 Results indicate that it is possible to determine an exercise-specific %1RM by measuring movement velocity for that exercise.
