Study Summary

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.

Primary Outcome

The plot of PCr peak height vs. time will be fitted with a mono-exponential equation whose free parameters are the recovery time constant (tau) and scaling coefficients. Percent change in tau between pre- and post-intervention scans will be our primary measurement of the maximal mitochondrial capacity response to exercise training.

Interventions

  • OTHER Isometric Contraction Exercise - Young Adults (Age group 18-39)
  • OTHER Isometric Contraction Exercise - Middle Age Adults (Age group 40-59)
  • OTHER Isometric Contraction Exercise - Old Adults (Age group >60)
