摘　　要：目的:揭示短时中等强度有氧运动改善成年早期肥胖者食物决策的神经基础。方法:采用食物决策范式和fNIRS技术考察了30 min中等强度有氧运动对28名平均年龄为19.35±0.91岁、平均BMI为31.53±2.52 kg/m2的肥胖成人的食物决策行为和前额叶激活的变化,并以29名平均年龄为19.79±0.86岁、平均BMI为21.14±1.59 kg/m2的正常成年人作为对照组探讨运动干预效果。结果:30 min中等强度有氧运动能显著提高成年早期肥胖者选择食物时考虑其健康价值的程度、选择健康食物的比例及自我控制成功时的l-DLPFC激活水平,但一次运动后未达到正常对照组水平。结论:短时中等强度有氧运动能有效改善成年早期肥胖者的食物决策。其神经基础之一可能是,短时中等强度有氧运动提高了l-DLPFC激活水平,促进自我控制能力提高,改变人们选择食物时健康和美味价值的权重,从而做出更多考虑健康价值的食物决策,提示可对成年早期肥胖者进行长期有氧运动干预。Objective:To explore the neurological basis of acute moderate aerobic exercise in improving food decision-making in obese young adults.Methods:Before and after a single 30 min acute moderate aerobic exercise,28 obese young adults aged at 19.35±0.91 were monitored accompanying brain activation by functional near-infrared spectroscopy(fNIRS)technology in a food decision-making task.29 normal BMI young adults aged at 19.79±0.86 were used as the control group.Result:30 min acute moderate aerobic exercise significantly increased the percentage of successful self-control trails and the percentage of disliked-healthy and liked-healthy food items.It decreased the percentage of liked-unhealthy food items,meanwhile increased l-DLPFC activation associated with food decision-making in obese young adults.Conclusions Acute moderate aerobic exercise increasing l-DLPFC activation to promote self-control may be a neurological basis to effectively improve food decision-making of obese young adults.
