Comparação de desempenho de agilidade, flexibilidade e força muscular de iniciantes universitários em voleibol submetidos a treino resistido

Abstract

The Volleyball is a sport that develops strength and agility, based on body movements such as jumping and changing direction, cognition, submitted to short intervals in a high-intensity environment, thus being able to stimulate aspects of cognition and range of muscle power and explosive force. The aim of this study is to observe sports performance in the components of physical fitness in the variables strength, agility, flexibility, vertical jump and body composition of beginners in volleyball after an intervention with physical exercises. This research is characterized by a field study, with an explanatory objective, of a quantitative nature with the manipulation of human samples, with pre and post-test characteristics, post intervention of 12 weeks of resistance training. The variables of interest were body circumferences, level of flexibility and agility, upper limb strength and lower limb strength. Descriptive results analyzed and presented with demonstration in mean and standard deviation. To verify the normality of the data using the Shapiro-Wilk Test. For association between the variables, the T-Paired Test was used with stratification of two groups. The significance levels were considered p= <0.05 and the confidence interval at 95% Male practitioners, mean age range of (24±3.21) years, 8 participants in the Experimental Group (EG) and 6 in the Group Control (GC). The result found showed an increase in the flexibility level gain of (5.05±1.1) centimeters/millimeters with a statistical difference (p=0.009) in the EG compared to the GC group, and comparing the EG with itself, there was a reduction of (2.06±0.21) seconds/milliseconds with statistical difference (p=0.012) regarding agility. No significant changes were found in the strength variable of upper and lower limbs, also in signs of hypertrophy. However, evidence of muscular resistance was found in the EG, expanding its results in comparison to the CG that showed signs of decline. In conclusion, performing plyometric resistance training in favor of improving sports performance, presents positive results in increasing physical fitness in the flexibility and agility components, in addition to preserving the muscular resistance of the lower and upper limbs.
