Abstract
The purpose of the present study has been to compare the knee flexo-extension exercise performed with the muscular belt (TM) with
the half squat exercise using different intensities. Likewise, the effort perceived by the subjects at each point was compared. Twelve
active male subjects were chosen for such purpose, they underwent vastus lateralis electromyographic recordings. The results obtained
suggest that there is not a significant difference when comparing the exercise done with the TM and no extra load to the half squat
exercise with an external load of 50 % of a maximal repetition (1RM). Likewise, there were no differences found between the TM with
10kg of extra load and the half squat with external load of 60 % of 1RM, and for the TM with 20 kg extra load and the half squat exercise
with external load of 70 % of 1RM. It can be derived from the results obtained that exercising with the TM can be a rather efficient
alternative for strength training; among its many advantages it can be remarked its “easy to use” handling, low economic cost, and,
above all, the fact that it can be a training method that can avoid injuries since it does not need excessively high external loads.
