Diet and Muscle Function In Older Adults

Not Applicable

Completed

• Conditions: Sarcopenia

• Registration Number: NCT02069314
• Lead Sponsor: Purdue University

Brief Summary

This research study was conducted to investigate the effects of a high protein diet on the efficiency of energy use at rest and at low-levels of physical activity. The hypothesis was that a high intake of dietary protein would result in a less efficient use of energy in skeletal muscle in older adults.
