APPLICATION OF 1 REPETITION MAXIMUM TEST IN MEN WITH AND WITHOUT VISUAL DEPRIVATION

Abstract

Introduction: An increasing demand for strength training (bodybuilding) by practitioners of physical exercises has led to an incessant search for ways to optimize results. It is already known that the control of physical training variables is necessary for greater safety and achievement of results. The one maximun repetition test (1RM) is a way of assessing muscle strength that is already well established in the literature. Thus, there are some data suggesting that the visual component can influence the strength assessed by this test. Objective: To evaluate the load value displaced during the execution of the 1RM test in men in two situations: with and without visual deprivation. Methods: A field research with a cross-sectional experimental approach was carried out, with 23 male subjects to perform two exercises with and without visual deprivation. The volunteers were divided into two groups: trained group and untrained group (without previous experience). The results were presented through tables and graphs created using the software GraphPad Prism version 6®. Results: No significant differences were found in the average values of load displaced in the barbell curl exercise in both groups (P>0.05), while for the bench press exercise differences were found in the trained and untrained group (P<0.05). Conclusion: Visual deprivation seems to be an influencing factor in the shifted load value in maximal tests only if it is tested in a form of exercise in which the subject may feel in danger.
