A Comparison of the Effects of Plyometric Training with and without Vessel Occlusion on Electromyographic Parameters

Doing plyometric training with and without the vessel occlusion is an effective practice for rapid increase of muscles strength their hypertrophy. We evaluated the effects of plyometric training with and without the vessel occlusion on electromyographic parameters.
In this quasi-experimental study, 22 females were selected through convenience sampling method. They were randomly categorized into 2 groups of plyometric training enforcing blood current limitation (30% 1RM) and plyometric training without enforcing blood current limitation (80% 1RM). The volunteers undertook 3 days per week training for 8 weeks. Before and after training, electromyographic parameters of the participants were evaluated. Analysis of covariance (ANCOVA) was used to evaluate changes in maximal elbow extension and flexion forces from pre-exercise session to the post-exercise session. The level of significance was set at P≤0.05.
Plyometric training with vessel occlusion increased electromyographic parameters compared to the plyometric training without the vessel occlusion.
Plyometric training with enforcing current limitations by low intensity is similar to plyometric training by high intensity on electromyographic parameters. Therefore, this kind of training may replace classic plyometric training.
