The purpose of this systematic review was to synthesize and evaluate current literature examining the effects of exercise on postprandial fat oxidation, as well as to provide future direction. A quantitative review was performed using meta-analytic methods. A moderator analysis was performed to investigate potential variables that could influence the effect of exercise on postprandial fat oxidation. Fifty-six effects from 26 studies were retrieved. There was a moderate effect of exercise on postprandial fat oxidation (Cohen's = 0.58 (95% CI, 0.39 to 0.78)). Moderator analysis revealed that sex, age, weight status, training status, exercise type, exercise intensity, timing of exercise, and composition of the meal challenge significantly affected the impact of prior exercise on postprandial fat oxidation. The moderator analysis also indicated that most previous studies have investigated the impact of prior moderate-intensity endurance exercise on postprandial fat oxidation in young, healthy, lean men. Suggested priorities for future research in this area include () an examination of sex differences in and/or female-specific aspects of postprandial metabolism; () a comprehensive evaluation of exercise modalities, intensities, and durations; and () a wider variety of test meal compositions, especially those with higher fat content. A systematic review of the impact of exercise on postprandial fat oxidation was performed using meta-analytic methods. Analysis revealed a moderate effect of exercise on postprandial fat oxidation. The presented data support a need for future studies to investigate sex differences and to include comprehensive evaluations of exercise modalities, intensities, and duration.
本系统评价的目的是综合和评估目前关于运动对餐后脂肪氧化影响的文献，并为未来的研究提供方向。采用荟萃分析方法进行定量综述。进行了一项调节分析，以研究可能影响运动对餐后脂肪氧化影响的潜在变量。从 26 项研究中检索到 56 个效应。运动对餐后脂肪氧化有中度影响（Cohen's = 0.58（95%CI，0.39 至 0.78））。调节分析显示，性别、年龄、体重状况、训练状况、运动类型、运动强度、运动时间和膳食挑战的组成显著影响了先前运动对餐后脂肪氧化的影响。调节分析还表明，大多数先前的研究已经调查了先前中等强度耐力运动对年轻、健康、瘦男性餐后脂肪氧化的影响。该领域未来研究的优先事项包括：（）检查餐后代谢中性别差异和/或女性特异性方面；（）全面评估运动方式、强度和持续时间；（）更广泛的测试餐组成，特别是那些脂肪含量更高的测试餐。采用荟萃分析方法对运动对餐后脂肪氧化的影响进行了系统评价。分析显示，运动对餐后脂肪氧化有中度影响。所提供的数据支持未来研究需要调查性别差异，并包括对运动方式、强度和持续时间的全面评估。
