Eight healthy and regularly physically active men, 44-69 years old, performed one- and two-legged dynamic knee extension exercise at increasing work intensities, including one leading to exhaustion. Leg blood flow increased linearly in relation to work rate, reaching a peak value of 5.1 +/- 0.4 l min-1. With a mean weight of quadriceps femoris of 2.2 +/- 0.1 kg, a peak perfusion of 2.3 +/- 0.1 l kg-1 min-1 was attained. The maximal leg oxygen uptake was 0.72 +/- 0.07 l min-1 (0.33 +/- 0.03 l kg… CONTINUE READING
