(1) Background: This study investigated the effect of acute barehanded whole body high-intensity intermittent exercise (HIIE) and moderate intensity and continuous exercise (MICE) at the same quantity of energy expenditure on postprandial triglyceride (TG) concentrations. (2) Methods: Nine healthy males completed three trials (HIIE, MICE and control (CON)) in a random order separated by at least 14 days. After each intervention, the participants rested for 12 h and consumed a high-fat test meal on the next day. The blood samples and respiratory exchange ratio were observed in the fasted state and for 4 h after consuming the test meal. (3) Results: The HIIE had a significantly higher area under the curve of postprandial fat oxidation rate than MICE ( = 0.027) and CON ( = 0.035) and exhibited significantly lower postprandial TG concentration than the MICE and CON at 2 and 4 h after the test meal. Moreover, the HIIE displayed a higher postprandial TG concentration area under the curve than MICE ( = 0.013) and CON ( = 0.048). (4) Conclusions: The present study concluded that acute barehanded whole body HIIE could significantly lower postprandial TG concentrations. It possibly can induce a rise in the postprandial fat oxidation rate.
(1) 背景：本研究旨在探讨相同能量消耗条件下，急性徒手全身高强度间歇运动（HIIE）和中等强度持续运动（MICE）对餐后甘油三酯（TG）浓度的影响。
(2) 方法：9 名健康男性以随机顺序完成了三种试验（HIIE、MICE 和对照（CON）），每种试验之间至少间隔 14 天。在每次干预后，参与者休息 12 小时，第二天再摄入高脂肪测试餐。在禁食状态和摄入测试餐后 4 小时观察血液样本和呼吸交换率。
(3) 结果：HIIE 的餐后脂肪氧化率曲线下面积明显高于 MICE（=0.027）和 CON（=0.035），且在测试餐后 2 小时和 4 小时，HIIE 的餐后 TG 浓度明显低于 MICE 和 CON。此外，HIIE 的餐后 TG 浓度曲线下面积明显高于 MICE（=0.013）和 CON（=0.048）。
(4) 结论：本研究表明，急性徒手全身 HIIE 可显著降低餐后 TG 浓度，可能会引起餐后脂肪氧化率升高。
