本研究探讨了运动前(4小时)摄取高糖和高蛋白膳食对短时间剧烈运动的影响方法受试者为大学运动系的5名男生,年龄,身高,体重及最大氧耗量分别为20±0.9岁,169.8±3.6cm,61.4±4.4kg和56.0±2.1ml/kg/分,每日进行有规律的运动。实验前,受试者连续三天进行剧烈运动,并摄取大量碳水化物(2784±162kcal/day,P:F:C=8:7:85)。且运动负荷测试前4小时摄取高糖膳食(高糖521kcal,P:F:C=7:3:90)或高蛋白膳食(高蛋白496kcal,P:F:C=75:16:9)。运动负荷试验在自行车测力计上进行,空蹬4分钟后,以每分钟150kpm/min递增,直至体力衰竭。在试验中,每分钟用罗氏袋收集呼出气,以乾式气体测量仪测量气体容积,
This study investigated the effects of high glucose and high protein diet before exercise (4 hours) on short-term strenuous exercise. Methods Five boys from University Sports Department were enrolled. Their age, height, weight and maximum oxygen consumption were 20 ± 0.9 years old, 169.8 ± 3.6 cm, 61.4 ± 4.4 kg and 56.0 ± 2.1 ml / kg / min for regular exercise daily. Subjects exercised strenuously for three consecutive days prior to the experiment and consumed large amounts of carbohydrate (2784 ± 162 kcal / day, P: F: C = 8: 7: 85). High glucose diet (high sugar 521 kcal, P: F: C = 7: 3: 90) or high protein diet (high protein 496 kcal, P: F: C = 75: 16: 9) were taken at 4 hours before exercise stress test. Exercise load test carried out on a bicycle dynamometer, empty pedal 4 minutes, 150kpm / min increments until physical exhaustion. In the experiment, exhaled air was collected in a Roche bag every minute, gas volume was measured with a dry gas meter,
