Abstract
The purpose of this study is to assess strength gains of the pectoralis major muscle in the non-dominant upper extremity (UE) after implementing blood flow restriction (BFR) and myofascial release (MFR).

Experimental Details

Interventions

Intervention(s)
Blood flow restriction and myofascial release will be the interventions used. Blood flow restriction (BFR) is a type of training where low intensity exercise is combined with blood flow occlusion to produce similar results as high intensity strength training. Myofascial release (MFR) is a manual technique using gentle sustained pressure to stretch the myofascial tissue, eliminate pain, and restore motion.

Experimental Design

Experimental Design
This will be a randomized controlled trial.
Experimental Design Details
Strength gains of the pectoralis major muscle in the non-dominant upper extremity (UE) will be assessed after implementing blood flow restriction (BFR) and myofascial release (MFR) for six weeks. The experimental group will receive a cross-hand pectoral MFR for three minutes. Prior to completing the BFR protocol on the chest fly machine, occlusion pressure will be obtained. Subjects will complete the BFR protocol for seven minutes using 20% of their one repetition maximum (1RM). Perceived exertion will be assessed before the BFR protocol and prior to the last set of the BFR protocol. After the BFR protocol is completed, subjects will be given one scoop of whey protein with water.
Randomization Method
A random number generator will be used for randomization.
Randomization Unit
Only one school will be used. Subjects will be randomly selected for the experimental (BFR and MFR) and control (BFR only) group.
