2.4.4. Repetition Maximum (RM) and Mean Propulsive Velocity (MPV)
knee flexion
This variable was measured through a test of progressive loads until reaching the 1RM in the squat exercise. The squat was performed with subjects starting from an upright position, with hips and knees extended, feet parallel and with an approximate biacromial width opening with the bar unloaded on their shoulders. Participants were asked to perform a uniform, uninterrupted descent at a controlled speed until the thighs and hips were parallel to the floor (approximately 90° of knee flexion), then the subject was asked to return to their starting position until they were completely vertical, with hips and knees in extension, demonstrating control over the load. This test has been validated in different populations, regardless of sex or age. The protocol used was performed according to that proposed by Pareja-Blanco et al. [
