Taxa de desenvolvimento de torque e desempenho muscular em jogadores amadores de futebol: um estudo transversal

Abstract

Introduction: neuromuscular performance has been frequently investigated among soccer athletes. However, although the rate of force development (RFD) has been shown to be sensitive to identify asymmetries between limbs, it has been little explored in the literature. Purpose: To compare RFD and muscle performance between the dominant (LD) and non-dominant (NDD) sides of amateur college soccer players. Methods: 28 amateur college soccer players participated in the study. The volunteers were submitted to the evaluation of RFD (peak torque, 30ms, 50ms, 100ms, 200ms), muscle performance, represented by isokinetic performance of knee flexors and extensors at speeds of 60°/s (1x5 repetitions) and 240°/s (1x30 repetitions) and isometric performance. Results: The variables peak torque and power of the flexors at 60°/s had statistically significant difference between the limbs, with the LD having higher values compared to the LND. However, there was no statistically significant difference in the comparison between the dominant and non-dominant sides for TDT, isometric torque, isokinetic performance of extensors, work and I/Q ratio of knee flexors (p<0.05). Conclusion: therefore, college soccer players do not exhibit limb imbalances in RFD and muscle performance.
