青少年摔跤、柔道与散打运动员集训期Hb变化

对首都体育学院36名(22男,14女)青少年摔跤、柔道与散打运动员在集训期间9周的Hb(血红蛋白)检测发现,男女青少年摔跤、柔道与散打运动员在集训期间Hb分别围绕145.8g/L、130.0g/L、151.1g/L、140.0g/L和145.2g/L平均水平波动变化;女青少年摔跤和柔道运动员Hb波动较大,其中女青少年柔道运动员存在Hb水平显著下降而低于其140.0g/L的平均水平的情况(P<0.05)。可见,青少年运动员在集训期间Hb水平呈现围绕某一个平均水平波动变化,这种波动是正常的变化过程;Hb指标更适合于对运动员进行系统的监控。在运用Hb指标对青少年运动员进行身体机能状况的监控时要密切关注其波动的范围,同时要将Hb水平的这种波动与青少年运动员训练期间的运动负荷或者比赛安排以及饮食营养状况密切地结合起来。另外,应该特别关注女青少年运动员的Hb波动情况。

Changes of Hb of Adolescent Athletes of Wrestling,Judo and Free Sparring during Their Training Session

Hb of 36 (22 males and 14females) adolescent athletes of wrestling,judo and free sparring from the Capital Institute of Physical Education has been measured during a training session of 9 weeks.Results show that the Hb indicators of these male and female athletes fluctuate around the averaged level of 145.8g/L,130.0g/L,151.1g/L,140.0g/L and 145.2g/L respectively.The Hb of the female wrestling and judo athletes fluctuates greatly,and the Hb of the female judo athletes is significantly lower than their average level of 140.0g/L occurred (P<0.05).It is thus clear that the Hb level of adolescent athletes during a training session tends to fluctuate around a certain level,which is a normal process,and that Hb index is more suitable for a systematic monitoring of athletes.Close attention should be paid on the range of fluctuation of Hb while the physical function of adolescent athletes is being monitored with the use of Hb.At the same time,this fluctuation should also be closely associated with their training load,competition schedule and nutrition status during a training session.Additionally,special attention should be paid to the Hb fluctuation of female adolescent athletes.
