| Abstract: | Standard parameters of external respiration at the aerobic–anaerobic transition and above the anaerobic (ventilatory) threshold (AT) were studied in highly trained athletes during an incremental treadmill test. The efficiency of the adaptive response (AR) was inferred from changes in the heart rate and VO2gradients beyond the AT. Several AR types differing in the efficiency of the AT to the physical load were identified. The most efficient AR was associated with a decrease in the heart rate gradient and an increase in the VO2gradient above the AT. The least efficient AR was associated with an increase in the heart rate gradient and a decrease in the VO2gradient above the AT. The efficiency of the AR to cyclic muscular load varies daily in individual athletes. |
