The influence of the time of ingestion of an evening meal following an intense bout of exercise on both muscle glycogen storage and blood glucose response on the next day early in the morning (12 h postexercise) was examined, In the first study, eleven healthy males were subjected to a 10 km run for 50 min pace following resistance exercise (bench press and half squat) at an intensity of 80% of one repetition maximum for 3 sets. An evening meal (73% carbohydrate, 18% fat, 9% protein ; percent of energy) was consumed within 1 h postexercise (1 P-EX) or from 3 h postexercise (3P-EX). Five subjects participated on two separate occasions and the remaining 6 subjects were divided randomly into either 1 P-EX or 3P-EX.Muscle biopsies were taken from the vastus lateralis immediately and 12 h postexercise. Muscle glycogen contents immediately postexercise were not significantly different between the 1 P-EX and the 3P-EX (mean*SD, 1P-EX vs. 3P-EX : 58.9*11.8 vs. 58.9*27.3 mmol/kg wet wt, n=5 ; 5 … More 6.4*15.3 vs. 60.0*25.3 mmol/kg wet wt, n=8). Muscle glycogen contents 12 h postexercise increased significantly in the 1 P-EX (81.0*20.0 mmol/kg wet wt, n=5, p<0.05 ; 84.2*22.6 mmot/kg wet wt, n=8, p<0.05) but not in the 3P-EX (62.5*24.0 mg/g wet wt, n=5 ; 67.3*20.8 mmol/kg wet wt, n=8). However, there was no difference in muscle glycogen contents 12 h postexercise between the two groups (1P-EX vs. 3P-EX : 81.0*20.0 vs. 62.5*24.0 mg/g wet wt, n=5 ; 84.2*22.6 vs. 67.3*20.8 mmol/kg wet wt, n=8). There was significant difference in the rate of glycogen repletion between the 1 P-EX and the 3P- (1 P-EX vs. 3P-EX : 2.28*2.0 vs. 0.30*2.87 mmol/kg wet wt/1 2h, n=5, p<0.05 ; 2.32*2.48 vs.0.62*2.30 mmol/kg wet wt/12h, n=8, p<0.1). These results suggest that compared with delaying the ingestion of a meal postexercise, the immediate ingestion of a meal postexercise will lead to more of a good chance of successful recovery of muscle glycogen store at. 12 h postexercise, In the second study, seven males were subjected to the same exercise and meal program as those in the first study. Blood glucose response following breakfast on the next day was examined at 0, 15, 30, 60, 90 min after meal. However, there was no difference in blood glucose responses between the two timings of an evening meal. Less

研究了剧烈运动后晚餐摄入时间对第二天清晨（运动后 12 小时）肌肉糖原储存和血糖反应的影响。在第一项研究中，11 名健康男性在抗阻运动（卧推和半蹲）后进行 10 公里跑，每次 50 分钟，强度为一次重复最大强度的 80%，共 3 组。晚餐（73% 碳水化合物、18% 脂肪、9% 蛋白质；能量百分比）在运动后 1 小时内 (1 P-EX) 或运动后 3 小时后 (3P-EX) 消耗。 5 名受试者参加了两次不同的活动，其余 6 名受试者被随机分为 1 P-EX 或 3P-EX。立即和运动后 12 小时从股外侧肌进行肌肉活检。运动后立即的肌糖原含量在 1 P-EX 和 3P-EX 之间没有显着差异（平均值*SD，1P-EX 与 3P-EX ：58.9*11.8 与 58.9*27.3 mmol/kg 湿重，n=5；5 … 更多 6.4*15.3 与 60.0*25.3 mmol/kg 湿重， n=8）。运动后 12 小时，1 P-EX 中的肌糖原含量显着增加（81.0*20.0 mmol/kg 湿重，n=5，p<0.05；84.2*22.6 mmot/kg 湿重，n=8，p<0.05），但 3P-EX 中没有显着增加（62.5*24.0 mg/g 湿重，n=5；84.2*22.6 mmot/kg 湿重，n=8，p<0.05）。 67.3*20.8 mmol/kg 湿重，n=8)。然而，运动后12小时两组之间的肌糖原含量没有差异（1P-EX与3P-EX：81.0*20.0与62.5*24.0mg/g湿重，n=5；84.2*22.6与67.3*20.8mmol/kg湿重，n=8）。 1 P-EX 和 3P- 之间的糖原补充率存在显着差异（1 P-EX 与 3P-EX ：2.28*2.0 与 0.30*2.87 mmol/kg 湿 wt/1 2h，n=5，p<0.05；2.32*2.48 与 0.62*2.30 mmol/kg 湿）重量/12小时，n=8，p<0.1）。这些结果表明，与运动后延迟进餐相比，运动后立即进餐更有可能成功恢复肌糖原储存。运动后 12 小时，在第二项研究中，七名男性接受了与第一项研究中相同的运动和膳食计划。餐后0、15、30、60、90分钟检查第二天早餐后的血糖反应。然而，两次晚餐时间之间的血糖反应没有差异。较少的
