Reducing postprandial triglycerides (TG) can lower the risk for cardiovascular disease. The purpose of this study was to perform a meta-analytic review of the literature to estimate the effect of prior exercise on postprandial lipemia. A total of 121 effects were found from 76 studies for the total TG response and 70 effects from 44 studies for the incremental area under the curve (iAUC) TG response. The weighted mean effect was moderate for the total TG response, Cohen's d = -0.60 (P < 0.0001), and for the iAUC response, Cohen's d = -0.59 (P < 0.0001). Moderator analysis revealed women exhibited a larger reduction (P < .01) in the total TG response following exercise (d = -0.96) than men (d = -0.57); high-intensity interval training induced a larger reduction (P < .05) in the iAUC response (d = -1.49) than aerobic (d = -0.58) or resistance (d = -0.13) exercise, and participants maintaining an energy deficit following exercise exhibited a greater reduction in the iAUC response (d = -0.67) compared with participants in energy balance (d = -0.28). We conclude that prior acute exercise reduces postprandial lipemia, with the magnitude of effect influenced by sex, type of exercise, and energy deficit following exercise.
降低餐后甘油三酯（TG）可以降低心血管疾病的风险。本研究的目的是对文献进行荟萃分析，以评估先前运动对餐后脂血症的影响。从 76 项研究中总共找到了 121 个影响总 TG 反应的效应，从 44 项研究中找到了 70 个影响增量曲线下面积（iAUC）TG 反应的效应。总 TG 反应的加权平均效应是中度的，Cohen's d = -0.60（P < 0.0001），对于 iAUC 反应，Cohen's d = -0.59（P < 0.0001）。 调节分析显示，女性在运动后总 TG 反应的降低幅度较大（P < 0.01）（d = -0.96），而男性（d = -0.57）；高强度间歇训练在 iAUC 反应中引起的降低幅度较大（P < 0.05）（d = -1.49）比有氧运动（d = -0.58）或阻力运动（d = -0.13）更大，运动后保持能量不足的参与者在 iAUC 反应中的降低幅度更大（d = -0.67）与能量平衡的参与者（d = -0.28）相比。我们得出结论，先前的急性运动可降低餐后脂血症，其影响程度受性别、运动类型以及运动后能量不足的影响。
