摘要
目的分析膳食营养搭配方案对散打运动员身体机制的影响作用。方法将102名散打运动员纳入研究,采取自身对照法,开展对比分析。即对比散打运动员采用膳食营养搭配方案前、后的身体机制、训练指标改善率、对膳食营养方案的满意度、情绪状态差异。结果运动员经膳食干预4周后各项身体机制指标变化状况均优于干预前(P<0.05);运动员训练指标改善率高于干预前(P<0.05);运动员对膳食营养方案的满意度为99.02%;散打运动员膳食干预后焦虑、抑郁得分均低于干预前(P<0.05);运动员干预4周后30 m冲刺速度、左膝屈曲、右膝屈曲以及深蹲重复做最大数量(one-repetition maximum,1RM)指标水平均优于干预前(P<0.05)。结论依据训练类型设计膳食营养搭配方案的应用,可改善散打运动员的身体机制,提高其各项运动指标,增强训练效果,且有助于缓解运动员的负性情绪。
Objective To analyze the effect of dietary nutrition on the body mechanism of Sanda athletes.Methods A total of 102 Sanda athletes were included in the study and the self-comparison method was adopted to carry out comparative analysis.Namely,the body mechanism,improvement rate of training indexes,satisfaction degree of dietary nutrition scheme and difference of emotional state before and after the adoption of dietary nutrition collocation scheme were compared.Results After 4 weeks of dietary intervention,the changes of body mechanism indexes were all better than those before intervention(P<0.05).The improvement rate of athlete training index was higher than that before intervention(P<0.05).The athletes'satisfaction with the dietary nutrition program was 99.02%.The scores of anxiety and depression after diet intervention were lower than before(P<0.05).After 4 weeks of intervention,30m sprint speed,left knee flexion,right knee flexion and 1RM(one-repetition maximum)level of squats were all better than those before intervention(P<0.05).Conclusion The application of dietary nutrition collocation scheme according to the training type can improve the body mechanism of Sanda athletes,improve their sports indexes,enhance the training effect,and help alleviate the negative emotions of athletes.
