To investigate the effect of interrupting sitting time with intermittent moderate exercise on acute postprandial plasma triglyceride (TG) in healthy children following high-fat meal consumption.
Twelve participants (8 girls; 4 boys), aged 12 ± 2 years (mean ± SD), completed two trials in the laboratory. On Day 1 (d1), sitting was interrupted with moderate intensity exercise every 30 min, and compared with day 2, (d2), where participants remained sedentary. On each testing day, participants consumed four high fat meals. Blood was sampled in a fasted state and 2-hourly for 6 h with the last sample taken on the 7th hour.
Overall, there were no significant differences in the area under the concentration-time curve between day 1 and day 2, for the 12 participants combined ( = 0.98). However, in eight of the 12 participants, triglyceride concentrations remained high on d2 at two, four and 6 h after baseline compared with d1 ( = 0.03).
When sitting was interrupted by short bouts of moderate intensity exercise there was a reduction in triglyceride concentrations in eight out of 12 participants. Possible reasons to account for the difference in response may include sexual maturation, gender differences, genetic conditions, or the rate of digestion and intestinal absorption.
研究通过间歇性适度运动中断久坐时间对健康儿童高脂餐后急性餐后血浆甘油三酯（TG）的影响。
12名参与者（8名女孩；4名男孩），年龄12±2岁（平均±标准差），在实验室完成两项试验。在第1天（d1），每隔30分钟进行中等强度运动以中断久坐，并与第2天（d2）进行比较，第2天参与者保持久坐状态。在每个测试日，参与者食用四顿高脂餐。在空腹状态下采血，并在6小时内每2小时采血一次，最后一次采样在第7小时。
总体而言，12名参与者合并计算时，第1天和第2天浓度-时间曲线下面积无显著差异（P = 0.98）。然而，在12名参与者中的8名中，与d1相比，d2时基线后2小时、4小时和6小时甘油三酯浓度仍较高（P = 0.03）。
当通过短时间的中等强度运动中断久坐时，12名参与者中有8名的甘油三酯浓度降低。导致反应差异的可能原因可能包括性成熟、性别差异、遗传状况或消化和肠道吸收速率。
