Efeito da fadiga muscular localizada ou geral no desempenho do salto vertical.

Abstract

Introduction: The elongate shortening cycle (CAE) is very important in jump-on-motion (SCM), which in turn is widely used in sports. The SCM can be used as an instrument to determine fatigue. The SCM performance is multi-articular and involves 3 joints, so muscles involved in these joints may influence SCM. Objective: To verify how much uni and bi-articular exercises interfere in the performance of SCM. METHODS: The sample consisted of 8 men with no type of osteomioarticular lesion that could interfere with the progress of the study, with mean age (mean age ± 26.75 years, mean weight ± 80.7 kg, mean height ± 1.75m). The volunteers underwent SCM evaluation before, immediately and 10 minutes after training bodybuilding until the concentric failure in different exercises, one in every 72 hours, being 4 uni-articular exercises and a multi. Results: All 5 trained exercises induced a drop in jump performance immediately after training (p <0.05). There was no significant difference in the interference between the squatting and the other exercises, but the extensor chair induced significantly more interference than the others in the SCM performance. Conclusion: Based on the results of this study, all exercises were efficient in promoting interference of SCM performance, in addition, the extensor chair was the exercise that most induced this interference.
