Energy balance
Mitochondrial efficiency (P/O ratio) is positively related to exercise efficiency (Gross and Net Efficiency) in older adults, and both are reduced by physical inactivity.
Your body's ability to convert oxygen into energy (mitochondrial efficiency) directly impacts how efficiently you move during exercise. Staying physically active helps maintain this efficiency, making your workouts feel easier and less taxing. This link highlights why consistent aerobic activity is beneficial for overall movement quality.
We found that both GE and NE efficiencies were similar between the active groups and lower in the OS group... we found that mitochondrial P/O ratio was also positively related to both GE (R2 = 0.22, P = 0.01) and NE (R2 = 0.13, P = 0.049)
