Effects of Essential Amino Acid Supplementation on Muscular Adaptations to 3 Weeks of Combined Unilateral Glenohumeral & Radiohumeral Joints Immobilisation

Short-term immobilisation results in a decrease in muscle size and strength. Ingestion of essential amino-acids (EAAs) stimulates net protein synthesis and supplementation is shown to improve lean body mass, strength and physical function, even without exercise. This study set out to determine whether EAA supplementation would attenuate immobilisation-induced changes in muscle characteristics.We conclude that EAA supplementation impacts positively on the immobilisation-induced changes in the structural and functional characteristic of the remaining muscle. Our findings are relevant to both sporting (e.g. off-season detraining
