Aging and the Mitochondrial Response to Exercise Training, Measured by Noninvasive 31P Magnetic Resonance Spectroscopy

The goal of the study is to determine whether aerobic or resistant exercise can improve in vivo mitochondrial capacity of skeletal muscle cells similarly in healthy younger, middle aged and older adults. This confers long-term changes in this tissue which in-turn contribute to improved metabolic health and functional capacity through epigenetic regulation of novel exercise response genes.
