摘要
目的:摸索适合划艇项目专项高强度间歇训练模型,通过训练生物学监控手段评价训练效果,为进一步挖掘划艇赛前专项训练提供个性化参考。方法:以浙江省国家队现役3名男子运动员为研究对象,通过连续3周两种高强度专项训练模型的实施,采用文献资料法、实验法、比较分析法对训练监控指标进行相关研究。主要指标包括常用的血乳酸(LA)、肌酸激酶(CK)、尿素氮(BUN)、血红蛋白(HB)、睾酮(T)、皮质醇(C),并尝试引入反映心脏功能的脑钠肽(BNP)、肌钙蛋白(CtnT)指标。结果:(1)不同状态下LA浓度与运动成绩来看,两种训练方法均能较好地反映3名运动员专项糖酵解供能系统的冲酸和耐酸能力,相对而言第一种训练方法对于冲酸能力的发展效果更佳。高强度运动后即刻、休息期LA变化趋势来看,3名队员的乳酸代谢清除能力不够强,证明运动员有氧能力还需进一步加强才能保证高强度训练效果。(2)通过赛前专项强度训练期CK、BUN、HB等指标的变化趋势来看,3名运动员经三周运动负荷量的积累,运动疲劳恢复的速度有所下降,说明机体承受训练负荷量的能力已明显减弱。结论:训练生物学监控评价结果反映3周专项高强度训练模型的实施,必须要以较好的专项有氧能力为基础,才能最大程度地提高运动员速度耐力发展水平。心脏功能敏感指标BNP和CtnT的介入研究,可为专项训练监控评价分析、运动员个体身体机能状态诊断及运动疲劳补剂的应用提供全面的数理依据。
Objective： In order to explore high-intensity intermittent training method in canoeing project, monitoring and testing surveying the state of athlete are applied to evaluate the training effect, and can provide references for training in per-competition Method： The objects are 3 canoeing athletes th at are affiliated sports team of Zhejiang province and Chinese national team. Objects are required to train under two different intensities in 3 weeks. We con-duct research in biochemical parameters by mean of experiment, comparison, analysis and literature material law. The common biochemical parameters for the state of object include blood lactic acid（LA） ,creatine kinase （CK） ,blood u-rea nitrogen （BUN） ,hemoglobin （HB）,serum testosterone （T）and cortisol （C） . Brain natriuretic peptide （BNP） and troponin （CtnT） are adopted for evaluatingcardiac function Results ： ？According to LA concentration and per-formance of athletes in two trainings, both of two training methods can improve capacities of acid buffering and acid resisting in glycolytic system. The former training method is more beneficial to acid buffering. According with the change trend of blood lactic acid （LA）during immediate period after training under high intensity and resting period, the ability of lactate removal of 3 athletes is insufficient, and the aerobic capacity of athletes should be improved for keeping training effect.② According with the change trend of blood creatine kinase （C K ） , blood urea nitrogen （BUN） and hemoglobin （HB） during training period, the speed of recovering from fatigue reduce while energy of ath-lete continuously consumes though 2 weeks high intensity training. This results show that the bearing capacity for high intensity training is weakened significantly. Conclusion： The results from monitoring biochemical parameters present that conducting 3 weeks high intensity training can improve speed -endurance in thelargest range, jus t basing on better aerobic capacity. BNP and CtnT that are adopted newly and sensitive to cardiac function in this research, could provide relatively overall reference for evaluating and surveying the effect of special training, determining the state of athlete, and applying supplement to athlete.
