title: [Determination of Aerobic-anaerobic Transition in Working Muscle Using EMG and Near Infrared-Spectroscopy Data].
abstract: A method to evaluate aerobic-anaerobic transition (AAT) during exercise is suggested. The subjects performed two tests with incremental increase of load: bicycle exercise and one leg knee extensions. In both tests the relation of deoxygenated hemoglobin (HHb) to EMG-activity of m. vastus lateralis during test has characteristic peak corresponding to AAT. The statistically significant correlation (r = 0.78, p < 0.05) between the load corresponding to AAT and anaerobic threshold (blood [La] = 4 mmol) was found during bicycle test. The method is applicable to determination of AAT during exercise of small muscle group.
