摘要: Seven male subjects completed cycle exercise bouts to the limit of tolerance on three occasions: (1) at a constant work rate (340+/-57 W; even-pace strategy; ES); (2) that was initially 10% lower than in ES trial but which then increased with time such it above after 120 s (slow-start SS); and, (3) higher decreased below (fast-start FS). The expected exhaustion predicted from pre-established power-time relationship all conditions. However, significantly greater (P<0.05) for FS (174+/-56 s) compared (128+/-21 and SS (128+/-30 In condition, (.)VO2 more rapidly toward its peak total O2 consumed first (ES: 5.15+/-0.78; SS: 5.07+/-0.83; FS: 5.36+/-0.84 L; P<0.05 vs SS). These results suggest fast-start pacing strategy might enhance by increasing oxidative contribution energy turnover hence "sparing" some finite anaerobic capacity across transition high-intensity exercise.
