营养干预对滑雪运动员运动性疲劳恢复效果的研究

Research on the Effect of Nutrition Intervention on the Recovery of Athletic Fatigue in Skiers

滑雪作为一项体能消耗巨大的运动,运动员在比赛过程中容易产生运动性疲劳,从而影响竞技状态和比赛成绩。运用实验法、访谈法和文献资料法,对7名男性青年滑雪运动员的日常饮食情况进行分析,从营养干预的角度研究其对滑雪运动员运动性疲劳恢复的效果。发现受测滑雪运动员营养摄入情况不够合理,在进行营养干预后,滑雪运动员的体脂率显著下降(P<0.01);有氧能力略有提高(P>0.05);无氧能力略有下降(P>0.05);能量代谢显著提高(P<0.01),表明营养干预对运动性疲劳的恢复能起到促进的效果。建议滑雪运动员重视健康饮食和膳食平衡,注意对多种维生素和视黄醇的补充,避免摄入超量的脂肪。

Skiing,as a sport that consumes a huge amount of physical energy,is prone to athlete fatigue during the competition,which can affect the competitive state and performance.This paper analyzes the daily diets of seven young male skiers in order to study the effect of nutritioninterventions on the recovery of athletic fatigue in skiers by the methods of experimental,after the nutritional intervention,the body fat percentage of skiers significantly decreased(P<0.01);aerobic capacity slightly increased(P>0.05);anaerobic capacity slightly decreased(P>0.05);and energy metabolism significantly increased(P<0.01),indicating that the nutritional intervention can have a facilitating effect on the recovery of athletic fatigue.It is recommended that skiers should have a healthy diet and dietary balance,pay attention to the supplementation of multivitamins and retinol,avoid excessive fat intake.
