Exercise In Aging: Can Handgrip Training Improve Skeletal Muscle Oxidative Recovery Kinetics?, Susie Chung, Ryan Rosenberry 2450189, Paul Bhella, Michael Nelson
International Journal of Exercise Science: Conference Proceedings
Loss of skeletal muscle function is a key factor contributing to reduced mobility and quality of life in aging individuals. While the exact mechanism remains unclear, impaired skeletal muscle oxidative capacity has been shown to play a major role. Exercise training increases oxidative capacity early in life; however, the potential for exercise to improve oxidative capacity later in life remains equivocal. PURPOSE: To test the hypothesis that 4 weeks of exercise training can improve skeletal muscle oxidative capacity in elderly individuals beyond the 6th decade of life. METHODS: To-date, 4 community-dwelling seniors from the local Dallas-Fort Worth …

Skeletal Muscle Oxygenation During Plantarflexion Exercise In Young-Old And Older-Old Adults, Arun Maharaj, Salvador J. Jaime, Justin Mason, Patrick Saracino, Arturo Figueroa

The aging process is associated with a gradual decrease in exercise performance, leg muscle blood flow and oxygenation, and endothelial vascular reactivity. Purpose: To examine potential differences in femoral artery flow-mediated dilation (fa-FMD) and calf muscle oxygenation (HbO2) during low-intensity plantarflexion exercise in older adults. Methods: 43 young-old (YO; n=24, 67 ± 1 years) and older-old (OO: n=19, 70 ± 1 years) individuals were included in this study. We measured body fat % and leg lean mass (LLM) by DEXA and handgrip maximal voluntary contraction (MVC) using a dynamometer. VO2max was estimated using a submaximal treadmill test. …
