We review recent findings on the ability of exercise to lower postprandial lipemia (PPL). Specifically, we answer why exercise is important in lowering PPL, when it is most effective to exercise to achieve this, what the preferred exercise is and how exercise reduces PPL. Most findings confirm the power of exercise to lower PPL, which is an independent risk factor for cardiovascular disease. Exercise is most effective when performed on the day preceding a high- or moderate-fat meal. This effect lasts up to approximately two days; therefore, one should exercise frequently to maintain this benefit. However, the time of exercise relative to a meal is not that important in real-life conditions, since one consumes several meals during the day; thus, an exercise bout will inevitably exert its lowering effect on PPL in one or more of the subsequent meals. Although moderate-intensity continuous exercise, high-intensity intermittent exercise, resistance exercise and accumulation of short bouts of exercise throughout the day are all effective in lowering PPL, submaximal, high-volume interval exercise seems to be superior, provided it is tolerable. Finally, exercise reduces PPL by both lowering the rate of appearance and increasing the clearance of triacylglycerol-rich lipoproteins from the circulation.
我们回顾了近期关于运动降低餐后血脂（PPL）能力的研究结果。具体来说，我们回答了为什么运动对于降低 PPL 很重要、何时运动最有效、首选的运动是什么以及运动如何降低 PPL。大多数研究结果证实了运动降低 PPL 的功效，因为 PPL 是心血管疾病的独立危险因素。在进食高脂肪或中高脂肪餐的前一天进行运动最有效。这种效果可持续约两天；因此，为了保持这种益处，应该经常运动。然而，在现实生活条件下，运动相对于进餐的时间并不是那么重要，因为人们一天会吃几顿饭；因此，一次运动必然会对随后的一餐或几餐中的 PPL 产生降低作用。尽管中等强度持续运动、高强度间歇运动、抗阻运动和全天积累短时间运动都能有效降低 PPL，但只要可以耐受，亚最大强度、大运动量的间歇运动似乎更优越。最后，运动通过降低甘油三酯丰富脂蛋白在循环中的出现速度和增加其清除率来降低 PPL。
