Abstract

This device produces asymmetric destabilizing forces by means of an elastic resistance (ER) cord. This study aimed to compare the level of muscle activity of LPHC, during the performance of three isometric exercises using TRX® Rip Trainer™. Twenty-two healthy, physically active men (mean age 23 ± 2.35 years) were evaluated during the performance of «Drag» (anterior), «Drive» (posterior) and «Stack» (rotation) isometrically resisted exercises, performed using TRX ® Rip Trainer ™. The muscle activity of longissimus, external oblique, gluteus medius, and biceps femoris was recorded by means of surface electromyography. There were differences regarding the side of the ER location in most of the evaluated muscles (p <.05). In addition, a Friedman test revealed differences between the exercises in relation to the evaluated muscle (p<.05). Usually, Stack exercise produces a higher level of activity in these muscles. The findings of this study describe the behavior of LPHC muscles during the use of TRX ® Rip Trainer ™.
