This study was designed to assess the effects of Ramadan fasting on the profile of mood state and perceived exertion in young soccer players and aerobic and anaerobic performances during the Yo-Yo, repeated sprint ability (RSA) and the Wingate tests.
Twenty junior male soccer players completed the Yo-Yo, the RSA, and the Wingate tests on three different occasions: one-week before Ramadan (BR), the second week (SWR) and the fourth week (ER) of Ramadan. The total distance (TD) covered and the estimated maximal aerobic velocity (MAV) during the Yo-Yo test were recorded. During the RSA test, peak power (PP) during each sprint, the percentage of decrement of PP (PD) and total work (Wtotal) were calculated. During the Wingate test, peak (P(peak)) and mean (P(mean)) powers and fatigue index (FI) were recorded.
TD and MAV (P=0.01) during the Yo-Yo test and PP (P=0.01, P=0.004, P=0.001, P=0.01, P=0.03 for sprints 1, 2, 3, 4, and 5, respectively) and Wtotal (P=0.02) during the RSA test were significantly higher during BR than ER. Furthermore, muscle fatigue during the RSA test increased significantly from BR to ER (P=0.01). P(peak) and P(mean) during the Wingate test decreased significantly from BR to SWR and ER (P<0.0005). FI was higher during SWR (P=0.001) and ER (P<0.0005) than BR. In addition, rating of perceived exertion scores and fatigue estimated by the profile of mood state questionnaire were higher during Ramadan in comparison with BR.
The present study suggests that both aerobic and anaerobic performances during the Yo-Yo, the RSA and the Wingate tests were affected by Ramadan fasting in young soccer players.
本研究旨在评估斋月禁食对年轻足球运动员情绪状态和主观疲劳感受的影响，以及对他们在Yo-Yo测试、重复冲刺能力（RSA）测试和温盖特测试中的有氧和无氧运动表现的影响。
20名青少年男性足球运动员在三个不同时间完成了Yo-Yo测试、RSA测试和温盖特测试：斋月前一周（BR）、斋月第二周（SWR）和斋月第四周（ER）。记录Yo-Yo测试中的总距离（TD）和估计的最大有氧速度（MAV）。在RSA测试中，计算每次冲刺的峰值功率（PP）、PP的下降百分比（PD）和总功（Wtotal）。在温盖特测试中，记录峰值（P(peak)）和平均（P(mean)）功率以及疲劳指数（FI）。
Yo-Yo测试中的TD和MAV（P = 0.01）以及RSA测试中PP（分别在冲刺1、2、3、4和5时，P = 0.01、P = 0.004、P = 0.001、P = 0.01、P = 0.03）和Wtotal（P = 0.02）在BR时显著高于ER。此外，RSA测试中的肌肉疲劳从BR到ER显著增加（P = 0.01）。温盖特测试中的P(peak)和P(mean)从BR到SWR和ER显著下降（P < 0.0005）。FI在SWR（P = 0.001）和ER（P < 0.0005）时高于BR。此外，与BR相比，斋月期间通过情绪状态问卷估计的主观疲劳感受评分和疲劳程度更高。
本研究表明，斋月禁食会影响年轻足球运动员在Yo-Yo测试、RSA测试和温盖特测试中的有氧和无氧运动表现。
