Brief Summary

The purpose of this study is to assess strength gains of proximal musculature in the nondominant upper extremity after implementing blood flow restriction (BFR) and myofascial release (MFR) with the supplementation of whey protein.

Detailed Description

The purpose of this study is to assess strength gains of proximal musculature in the nondominant upper extremity after implementing blood flow restriction (BFR) and myofascial release (MFR) with the supplementation of whey protein. Blood flow restricted (BFR) exercise is the brief and non-continuous blockage of venous blood flow using a device that restricts the flow of blood while exercising. This technique is used to produce hypertrophy (muscle growth) and strength responses while exercising at a lighter load than traditionally required to produce a similar response. Myofascial release (MFR) is a technique that involves applying gentle sustained pressure into the myofascial connective tissue restrictions to eliminate pain and restore motion.
