Correlation between total volume and markers of muscle damage after eccentric exercises with different intensities in protective effect of charge
Abstract
It is known thateccentric exercisecausesdamage to themicro-architecture of the muscle fibercausingpainand decreased range of motion until 96 hours after the exercise session. Objective: To investigate the correlation between the volume of aneccentric exercise at different intensities in the micro-surrogate markers of muscle damage. Materials and Methods: In a randomized crossover design14 healthy men (25±6 year sold,174 ±7cm height, 72 ±6 kg body weight) participated voluntarily in the study and under went two sessions of two series of unilateral biceps curl (phase eccentric) until volitional exhaustion at 75% or 130% of 1 repetition maximum using the non-dominant limb. We used agoniometer measuring the plastic range of motion. The subjective perception of pain was measured from a visual analogue scale on palpation and the maximum extent. The variables were measured before, immediately after, 48 and 96h after exercise. MixedANOVA for repeated measures was used to compare variables and if necessary post hoc Bonferroni. The level of significance was p<0.05. Results: Significant reduction of the ADM with a difference between the intensities. Significant increase in the perception of pain on palpation and elbow extension with no difference between the intensities. There was no significant correlation between the total volume and ADM or the perception of pain in any of the intensities. Conclusion: The effects of eccentric exercise are more pronounced the higher the intensity, but these effects did not correlate with the total volume.
