目的:观察女子自由式摔跤运动员训练和比赛前后的血氨变化,探讨血氨评定和监控该项目训练的可行性。
方法:安徽省女子自由式摔跤队运动员13名和备战2004年雅典奥运会的国家女子自由式摔跤队运动员7名(包括4名奥运会参赛运动员),系统跟踪测试运动员训练和比赛前后血氨以及有关指标的变化。
结果:(1)不同水平女子摔跤运动员安静血氨水平无显著性差异(P>0.05);(2)控(降)体重对血氨无显著影响(P>0.05);(3)不同水平女子摔跤运动员比赛时血乳酸无显著性差异(P>0.05),但高水平运动员比赛时的血氨显著高于低水平运动员(P<0.01)。
结论:(1)运动水平和控(降)体重对女子自由式摔跤运动员安静血氨无明显影响;(2)在评定强度负荷时,极限以下强度血乳酸更为敏感,极限强度血氨更为敏感,血氨可作为评定磷酸原(ATP-CP)代谢系统和极限负荷强度敏感而可靠的指标;(3)血氨可能是评定运动员训练水平和运动能力的指标。 关键词: 女子摔跤运动员;血乳酸;血氨
Objectives: The present study aimed at investigating the variations of blood ammonia before and after training and competition in female wrestlers, and the feasibility of justifying and monitoring training in female wrestlers through the variation of blood ammonia.
Methods: The blood ammonia and other variables of thirteen female wrestlers of Anhui province team and seven of national team were measured during training and competition.
Results:(1)There was no significant difference in blood ammonia(P>0.05) in female wrestlers of different levels at rest.(2)There was no significant difference in blood ammonia(P>0.05) during weight reducing period in female wrestlers.(3)There was no significant difference in blood lactate(P>0.05) in female wrestlers of different levels during competition, while blood ammonia of higher level female wrestlers was significant higher than those of lower level(P<0.01).
Conclusions: (1) Training and weight reduction do not affect blood ammonia at rest. (2)Blood ammonia is the sensitive indicator of monitoring the depletion of ATP-CP and maximal intensity. (3) Blood ammonia is a possible indicator of training level and the ability to compete.
Key words: female wrestler, blood lactate, blood ammonia
