Effects of aerobic exercise during recovery from eccentric contraction on muscular performance, oxidative stress and inflammation

Abstract

This study investigated the effects of aerobic exercise during recovery from eccentric contraction (EC) on muscular performance, oxidative stress, and inflammation. Nineteen male subjects between 18 and 29 years were divided into unexercised (control, n = 9) and exercised (n = 10) groups. Initially, the subjects performed EC as 3 sets until exhaustion with elbow flexion and extension on the Scott bench at 80% in 1RM, followed by four aerobic exercise sessions. The results obtained indicated (p > 0.05) that aerobic physical exercise during the recovery period does not improve muscle performance (isometric strength and muscular fatigue), oxidative stress parameters (lipid peroxidation, protein oxidation and antioxidant enzyme activity), and inflammatory cytokines (IL-1β, TNF-α, IL-10). In conclusion, the aerobic exercise during the recovery period does not alter the parameters of performance, oxidative stress and inflammation induced by the EC.
