Chronic Obstructive Pulmonary Disorder and Acute Exercise

NCT02780219 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 57

Last updated 2025-02-03

No results posted yet for this study

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.

Conditions

  • Pulmonary Disease, Chronic Obstructive
