A Stress Test to Evaluate the Physical Capacity of Performing L-1 Anti-G Straining Maneuvers
Abstract
To evaluate the physical capacity fo performing L-1 anti -G straining maneuvers (AGSM), 9 subjects participated in stress test protocols which were designed to use repetitive AGSM exercise on the ground. Physiological responses of oxygen uptake (VO2), minute pulmonary ventilation (VE), respiratory exchange ration (RER) and heart rate (HR) were determined for steady state exercise at AGSM duty cycles of 20%, 25%, 33% and 50%. These exercise loads consisted of repeated 5-second L-1 AGSM maneuvers and were each followed by a 20, 15, 10, 5- second rest period, respectively. A total of 36 min progressive intensity (with respect to duty cycle), discontinuous protocols were used where exercise at each duty cycle was 4 min in duration followed by a 5 min rest interval. Physiological responses were found to be fairly linear in relationship to duty cycles.
