Análise da flexibilidade, força e atividade eletromiográfica nos músculos isquiotibiais após alongamento estático, balístico e por facilitação neuromuscular proprioceptiva

Abstract

Analysis of flexibility, strength and muscular activity on the hamstrings muscles after the use of the following stretching techniques: static, ballistic and PNF Aim: to analyze and compare the deleterious effects of stretching of the hamstrings muscles on flexibility, strength and muscular activity after the use of the following stretching techniques: static, ballistic and PNF. Methods and Materials used: 30 women were divided in three groups and each of these groups was submitted randomly to one of the three stretching techniques. The data regarding the individual flexibility, strength and muscular activity were analyzed in a pre and after tests. The dominant member was considered as the control group. Results: the analysis demonstrated a considerable statistic increase on flexibility; however, a considerable statistic decrease was noticed on the muscular strength and nothing happened to the electromyography after the use of the stretching techniques. When the three stretching techniques were compared between each other, no difference was found. The adopted level of significance was of p ≤ 0,05. Conclusion: considering the fact that there is no difference between the stretching techniques applied to the willing helpers, we end up agreeing with the literature: the static stretching is the most indicated/recommended between the three analyzed techniques.
