A single bout of cycling or running performed in the evening can reduce postprandial lipaemia (PPL) the following morning, although this is currently unknown for upper-body exercise. The aim of this study was to determine if a bout of arm-crank exercise (high-intensity interval [HIIE] or moderate-intensity continuous [MICE]), can attenuate PPL in noninjured individuals. Eleven healthy and recreationally active participants (eight males, three females; age: 27 ± 7 years; body mass index: 23.5 ± 2.5 kg·m) volunteered to participate in three trials: HIIE (10 × 60 s at 80% peak power output), MICE (50% peak power output of isocaloric duration), and a no-exercise control condition. Each exercise bout was performed at 18:00, and participants consumed a standardised evening meal at 20:00. Following an overnight fast, a 5-h mixed-macronutrient tolerance test was performed at 08:00. There were no significant differences in triglyceride incremental area under the curve between HIIE (192 ± 94 mmol·L per 300 min), MICE (184 ± 111 mmol·L per 300 min), and the no-exercise condition (175 ± 90 mmol·L per 300 min) ( = 0.46). There were no significant differences in incremental area under the curve for glucose ( = 0.91) or insulin ( = 0.59) between conditions. Upper-body MICE and HIIE performed in the evening do not influence PPL the following morning, in normotriglyceridemic individuals. Clinical Trials Registration: NCT04277091. Arm-crank exercise has no effect on PPL when performed the evening prior to a mixed-macronutrient meal test. Upper-body sprint interval exercise should be investigated as a potential solution to reduce PPL.
单次晚间骑行或跑步可以降低次日清晨的餐后血脂（PPL），但目前尚不清楚上肢运动是否如此。本研究旨在确定单次手臂曲柄运动（高强度间歇[HIIE]或中等强度连续[MICE]）是否可以减轻非受伤个体的 PPL。11 名健康且有规律运动的参与者（8 名男性，3 名女性；年龄：27 ± 7 岁；体重指数：23.5 ± 2.5 kg·m）自愿参加了三项试验：HIIE（10×60 s，80%峰值功率输出）、MICE（50%峰值功率输出等热量持续时间）和无运动对照条件。每次运动均在 18:00 进行，参与者在 20:00 进食标准晚餐。禁食过夜后，于 08:00 进行 5 小时混合宏量营养素耐受测试。HIIE（192 ± 94 mmol·L per 300 min）、MICE（184 ± 111 mmol·L per 300 min）和无运动条件下（175 ± 90 mmol·L per 300 min）的甘油三酯增量 AUC 无显著差异（P = 0.46）。血糖（P = 0.91）和胰岛素（P = 0.59）增量 AUC 在条件之间也没有显著差异。在正常甘油三酯血症个体中，晚间进行上肢 MICE 和 HIIE 运动不会影响次日清晨的 PPL。临床试验注册：NCT04277091。在混合宏量营养素膳食测试前的晚上进行手臂曲柄运动不会影响 PPL。应进一步研究上肢冲刺间歇运动作为降低 PPL 的潜在解决方案。
