Alterações na força muscular em participantes da modalidade voleibol em um programa de esporte universitário

Abstract

Muscle strength is essential for the practice of physical exercises and daily activities, and also an important predictor of human health for both sexes. Knowing the importance of strength for a variety of sports and, specifically in this text, volleyball, we have its use during the practice of the essential sport, as it is in constant use. We have muscular strength then as an essential physical capacity. The aim of this study was to evaluate the effects of volleyball practice in university students on the strength physical fitness component (lower limb strength, handgrip strength, abdominal strength and upper limb strength). The current study was characterized as a cross-sectional quantitative study and was carried out in the pre-test and post-test models. The sample consisted of university students participating in a sports program at the Federal University of Alagoas - UFAL, Campus A.C. Simões, supported by the Institute of Physical Education and Sport - IEFE. The program in general serves around 850 undergraduates with different sports. For the abdominal strength test, a wide improvement was obtained in the number of excellent, from 11 to 14 boys in the pre and post test, respectively; for girls an improvement from 1 to 6 in the number classified as “good”. For the vertical jump test, it was seen that men classified as "good" in the pre-test was 0, however, after the intervention this number increased to 3. For girls classified as "below average" in the pre-test we had 8 and, in the post test, this number markedly reduced to 4. For arm flexion we had no relevant changes for males. For females, a strong migration from 5 “above average” in the pre-test to 10 in the post-test was visualized. For the handgrip test in men and women, data stability was observed, without marked variations. In this study, the importance of sports practice at the university is concluded in order to achieve improvements in physical fitness. Improvements were observed in the variables of abdominal strength, upper limb strength, lower limb strength of the participants' health-related physical fitness. However, no relevant improvements were identified in subjects' manual strength (dynamometry). This time, it is recommended to continue university sports programs to maintain the physical fitness valences of academics, while studies can be directed specifically to improve these variables.
