Uma sessão de saltos pliométricos eleva a dor muscular de início tardio por até 48 horas

Introduction: Plyometric jumps are exercises that involve fast muscle actions in the eccentric phase followed immediately by a concentric action and result in greater magnitude of muscle damage. Among the indirect methods for analyzing muscle damage is the measurement of delayed onset muscle soreness (DOMS) through pain perception scales. Objective: To analyze the effect of a plyometric jumping protocol on the DOMS in physically active subjects. Material and methods: Twenty physically active male subjects aged 18 to 30 years old, separated randomly into experimental (n = 10) and control (n = 10) groups. Body mass, height and skinfold thickness were measured, and the short version International Physical Activity Questionnaire was applied. Then the muscle damage protocol was performed, and the pain intensity was measured by the Visual Analog Scale. A significance level of p <0.05 was adopted. Results: The experimental group's DOMS was higher than the baseline and the control group at 24h and 48h. Discussion: These results demonstrated that at 24 and 48h the volunteers were not yet recovered from the proposed session. Additionally, they point to the need for intensity control in this protocol, since the duration of the DOMS could be related to the fall height. Conclusion: A session of plyometric jumps causes DOMS in physically active subjects and that the time period of 72h was sufficient for full recovery.
