SUMMARY
Objective. The purpose of this study was to compare muscle power gains when trained men were submitted to the ischemia preconditioning (IPC) and Self-myofas­cial release (SMR).
Methods. This study included 16 men healthy and regular practitioners of resistance training. Prior to training sessions, the Muscle-Bone cross sectional area was estimated (Muscle-Bone CSA estimate). All participants performed 3 sets of 5 repetitions of the deadlift exercise after IPC and SMR at random. Participants underwent to two evalua­tions (IPC and SMR) with Linear Position Transducer during 1st set, 2nd set, and 3rd set in the deadlift exercise. All evaluations were performed in a two-session separated by 48 hours to assess of the peak muscle power (watts) and velocity (m/s).
Results. The two-way ANOVA no showed interaction effects group × timing for peak power, velocity and repetition for peak power after interventions protocol. However, Pearson’s correlation was found to be significant between Peak power and Muscle- Bone CSA estimate-THIGH for left (p < 0.03) and right (p < 0.04) limbs after IPC protocol. Moreover, significant correlation was also observed between Peak power and Muscle-Bone CSA estimate-LEG for left (p < 0.01) and right (p < 0.03) limbs after IPC protocol.
Conclusions. Our data contribute to the qualitative and quantitative understanding of the correlation between Peak power and Muscle-Bone CSA estimate using of the IPC protocol which becomes a good option for improving neuromuscular performance in modalities that demand muscle power.
