The aim of this study was to investigate the effects of Ramadan fasting on anaerobic power and capacity and the removal rate of lactate after short time high intensity exercise in power athletes. Ten male elite power athletes (2 wrestlers, 7 sprinters and 1 thrower, aged 20-24 yr, mean age 22.30 ± 1.25 yr) participated in this study. The subjects were tested three times [3 days before the beginning of Ramadan (Pre-RF), the last 3 days of Ramadan (End-RF) and the last 3 days of the 4(th) week after the end of Ramadan (After-RF)]. Anaerobic power and capacity were measured by using the Wingate Anaerobic Test (WAnT) at Pre-RF, End-RF and After- RF. Capillary blood samples for lactate analyses and heart rate recordings were taken at rest, immediately after WAnT and throughout the recovery period. Repeated measures of ANOVA indicated that there were no significant changes in body weight, body mass index, fat free mass, percentage of body fat, daily sleeping time and daily caloric intake associated with Ramadan fasting. No significant changes were found in total body water either, but urinary density measured at End-RF was significantly higher than After-RF. Similarity among peak HR and peak LA values at Pre-RF, End- RF and After-RF demonstrated that cardiovascular and metabolic stress caused by WAnT was not affected by Ramadan fasting. In addition, no influence of Ramadan fasting on anaerobic power and capacity and removal rate of LA from blood following high intensity exercise was observed. The results of this study revealed that if strength-power training is performed regularly and daily food intake, body fluid balance and daily sleeping time are maintained as before Ramadan, Ramadan fasting will not have adverse effects on body composition, anaerobic power and capacity, and LA metabolism during and after high intensity exercise in power athletes. Key pointsNo significant changes were assessed on body composition, daily sleeping time and caloric intake, and body fluid balance in regularly trained power athletes during Ramadan fasting.Ramadan fasting has no adverse effect on power outputs of short time high intensity exercise.No influence of Ramadan fasting on LA metabolism during high intensity exercise and passive recovery in regularly trained power athletes.
本研究旨在探讨在力量型运动员中，斋月斋戒对无氧能力和乳酸去除率的影响。10 名男性精英力量型运动员（2 名摔跤手、7 名短跑运动员和 1 名投掷运动员，年龄 20-24 岁，平均年龄 22.30 ± 1.25 岁）参与了这项研究。受试者在以下三个时间点进行了测试[斋月开始前 3 天（Pre-RF）、斋月最后 3 天（End-RF）和斋月结束后第 4 周的最后 3 天（After-RF）]。在 Pre-RF、End-RF 和 After-RF 时，使用 Wingate 无氧测试（WAnT）测量无氧能力和容量。在休息时、WAnT 后立即以及整个恢复期采集毛细血管血样进行乳酸分析和心率记录。重复测量方差分析表明，体重、体重指数、去脂体重、体脂百分比、每日睡眠时间和每日热量摄入与斋月斋戒无关。总身体水分也没有明显变化，但在 End-RF 时测量的尿比重明显高于 After-RF。Pre-RF、End-RF 和 After-RF 时的最大心率和最大 LA 值相似，表明 WAnT 引起的心血管和代谢应激不受斋月斋戒的影响。此外，高强度运动后的无氧能力和乳酸去除率也不受斋月斋戒的影响。本研究结果表明，如果力量型运动员定期进行力量训练，并且保持与斋月前相同的每日食物摄入、体液平衡和每日睡眠时间，那么斋月斋戒不会对身体成分、无氧能力和高强度运动后的 LA 代谢产生不利影响。关键点在定期进行力量训练的运动员中，斋月期间的身体成分、每日睡眠时间和热量摄入以及体液平衡没有明显变化。斋月斋戒对短时间高强度运动的功率输出没有不良影响。斋月斋戒对定期进行力量训练的运动员高强度运动期间和被动恢复期的 LA 代谢没有影响。
