STATIC LOADS ON THE LOWER BACK FOR TWO MODALITIES OF THE ISOMETRIC SMITH SQUAT

By: Pascual Marques-Bruna

Price: Free

Introduction: The squat is one of the most effective exercises in athletic training. However, there is a scarcity of research that reports the muscular and joint loads in the lumbar region incurred when performing the high bar and the low bar isometric squat modalities in a Smith machine. Therefore, this study aims to determine the muscle force of the lower back extensors, and the compressive (Rc) and shear (Rs) forces at the lumbosacral joint for the one repetition maximum (1RM) high bar and low bar isometric parallel-depth Smith squats.
