About

Introduction: studies on resistance training of low intensity associated with blood flow restriction in recent years, although there are still gaps that can be explored in relation to their physiological phenomena when associated with eccentric training. In this way, from there the exploration becomes relevant the investigation of eccentric training associated to an RFS. Objective: To analyze and compare the effects of a high intensity and low intensity intensive resistance training associated with an RFS (TREAI-RFS and TREBI-RFS) with a high intensity eccentric resistance training without RFS (TREAI) in knee extensors. Method: The study will consist of 45 male participants, allocated from a stratified randomization into three groups: TREAI (n = 15), TREAI-RFS (n = 15) and TREBI-RFS (n = 15). Participants underwent a training program with a minimum of 40% without RFS, 80% with RFS and 40% with CVS of CVIM, 3 times a week, and the outcomes of muscle strength, muscle structure, power test and Endothelial growth will be assessed one week before, the fourth week and one week after the end of the training program. In addition, clinical markers of perception and recovery effort are investigated before and after a session. The graph used is descriptive and descriptive, as it is used as a model of analysis of variance for the analysis of replications without a two-factor scheme, which provides detailed information on how the measures are repeated, neither. A whole statistical analysis can reach the level of significance of 5%.

61 participants in 4 patient groups

HIET (n = 15)

Active Comparator group

Description:

High intensity eccentric training: A high intensity (80% isometric peak) eccentric training of the knee extensors in the isokinetic will be performed during 6 weeks, 3 times a week.
