Correlation between exercise capacity and muscle oxidative capacity. HF patients have lower exercise capacity but similar muscle oxidative capacity compared to sedentary controls; both exercise capacity and muscle oxidative capacity are lower in these groups compared with active controls. The decreased exercise capacity in HF, therefore, cannot be entirely attributed to decreased muscle oxidative capacity. Open circles=HF, open triangles=sedentary controls, closed triangles=active controls. Modified from reference 16.
