Investigating Proximal Muscle Strength Effects by Incorporating Proximal Muscle Lengthening

Study Overview
=================
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.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: The control group will receive a sham myofascial release pectoralis minor release intervention. The experimental group will receive a myofascial release pectoralis minor release intervention. Both groups will receive blood flow restriction exercise to strength the scapula retractors.
Masking: Single
