Low-volume, high-intensity exercise is a time-efficient method of inducing physiological responses and may also improve glucose homeostasis. Therefore, effects of two different volumes of sprint-interval cycling on post-prandial blood glucose were assessed.
Twenty healthy young males undertook two Wingate anaerobic tests (2WAT), four Wingate anaerobic (4WAT) and without-exercise (CON) 90 min after eating a standard meal. Blood glucose was examined at 60, 90, 105, 120, 135 and 150 min post-prandially.
2WAT and 4WAT both accelerated the decrease of blood glucose compared with CON (P<0.05). There were significant reductions at 120 (4.45 ± 0.64 vs. 4.93 ± 0.9 vs. 5.68 ± 0.69), 135 (4.28 ± 0.50 vs. 4.48 ± 0.75 vs. 5.54 ± 0.6) and 150 min (4.64 ± 0.71 vs. 4.71 ± 0.73 vs. 5.36 ± 0.48, all P<0.05). Blood glucose at 120 min was lower after 2WAT than 4WAT (4.45 ± 0.64 vs. 4.93 ± 0.9, P<0.05), this producing a significant statistical interaction between groups and post-exercise time (P<0.005).
2WAT and 4WAT tests both accelerate the post-prandial decrease in blood glucose in young healthy males, 2WAT being superior to 4WAT in producing this response, even though 2WAT is easier to perform and less time consuming.
小运动量、高强度运动是一种高效诱导生理反应的方法，还可能改善葡萄糖稳态。因此，评估了两种不同运动量的冲刺间歇骑行对餐后血糖的影响。
20名健康年轻男性在进食标准餐后90分钟进行了两次温盖特无氧测试（2WAT）、四次温盖特无氧测试（4WAT）以及不运动（CON）测试。在餐后60、90、105、120、135和150分钟检测血糖。
与CON组相比，2WAT和4WAT均加速了血糖下降（P<0.05）。在120分钟（4.45±0.64对4.93±0.9对5.68±0.69）、135分钟（4.28±0.50对4.48±0.75对5.54±0.6）和150分钟（4.64±0.71对4.71±0.73对5.36±0.48，均P<0.05）时血糖有显著降低。2WAT后120分钟的血糖低于4WAT（4.45±0.64对4.93±0.9，P<0.05），这在组间和运动后时间之间产生了显著的统计学交互作用（P<0.005）。
2WAT和4WAT测试均加速了年轻健康男性餐后血糖的下降，2WAT在产生这种反应方面优于4WAT，尽管2WAT更易于实施且耗时更少。
