Method of assessment of muscle oxygen consumption by near-infrared spectroscopy. Measured at the left rectus femoris and gastrocnemius muscles. At rest and immediately after the end of exercise at each intensity, the proximal part of the leftf emoral region was occluded at 600 mmHg for 1 minute, during which oxygenated hemoglobin levels were acquired. "A" denotes a slope of oxygenated hemoglobin levels acquired at exercise, while "B" denotes that at rest. A value of A/B represents a ratio of oxygen consumed during exercise to that consumed at rest
