The Effects of Acute Resistance Exercise on Protein and Amino Acid Metabolism in Chronic Obstructive Pulmonary Disease

Texas A&M University·interventional·Posted May 23, 2016·Updated Feb 3, 2025

In Brief

A clinical study evaluating stable amino acid infusion, acute exercise with amino acid infusion, and 1 other intervention for Pulmonary Disease, Chronic Obstructive. Completed, enrolled 57 participants across 1 site.

Detailed Summary

For this study a resistance bout will be performed in order to promote the robust response of protein synthesis. Type II muscle fibers often exhibit more atrophy than type I fibers in COPD subjects therefore specifically targeting them in an exercise protocol could have more beneficial outcome for these individuals.
