The purpose of this systematic review was to synthesize the results from current literature examining the effects of prior exercise on the postprandial triglyceride (TG) response to evaluate current literature and provide future direction. A quantitative review was performed using meta-analytic methods to quantify individual effect sizes. A moderator analysis was performed to investigate potential variables that could influence the effect of prior exercise on postprandial TG response. Two hundred and seventy-nine effects were retrieved from 165 studies for the total TG response and 142 effects from 87 studies for the incremental area under the curve TG response. There was a moderate effect of exercise on the total TG response (Cohen's d = -0.47; p < .0001). Moderator analysis revealed exercise energy expenditure significantly moderated the effect of prior exercise on the total TG response (p < .0001). Exercise modality (e.g., cardiovascular, resistance, combination of both cardiovascular and resistance, or standing), cardiovascular exercise type (e.g., continuous, interval, concurrent, or combined), and timing of exercise prior to meal administration significantly affected the total TG response (p < .001). Additionally, exercise had a moderate effect on the incremental area under the curve TG response (Cohen's d = -0.40; p < .0001). The current analysis reveals a more homogeneous data set than previously reported. The attenuation of postprandial TG appears largely dependent on exercise energy expenditure (∼2 MJ) and the timing of exercise. The effect of prior exercise on the postprandial TG response appears to be transient; therefore, exercise should be frequent to elicit an adaptation.
本系统评价的目的是综合现有文献中关于既往运动对餐后甘油三酯（TG）反应影响的研究结果，以评估当前文献并为未来研究提供方向。采用荟萃分析方法进行定量综述，以量化个体效应量。进行了调节因素分析，以研究可能影响既往运动对餐后TG反应影响的潜在变量。从165项研究中检索到279个关于总TG反应的效应量，从87项研究中检索到142个关于曲线下增量面积TG反应的效应量。运动对总TG反应有中等程度的影响（科恩d值=-0.47；p<0.0001）。调节因素分析显示，运动能量消耗显著调节了既往运动对总TG反应的影响（p<0.0001）。运动方式（如心血管运动、抗阻运动、心血管运动与抗阻运动结合或站立）、心血管运动类型（如持续运动、间歇运动、同时进行运动或联合运动）以及进餐前运动的时间显著影响总TG反应（p<0.001）。此外，运动对曲线下增量面积TG反应有中等程度的影响（科恩d值=-0.40；p<0.0001）。当前分析显示，与之前报道的相比，数据集更具同质性。餐后TG的降低似乎在很大程度上取决于运动能量消耗（约2兆焦耳）和运动时间。既往运动对餐后TG反应的影响似乎是短暂的；因此，应频繁运动以引发适应性变化。
