Effects of Ischemic Preconditioning or Self-Myofascial Release on Muscle Power in Men Trained

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.
