| 摘 要： | Na＋，K＋-ATP酶活性对训练负荷具有较高的敏感性，利用Na＋，K＋-ATP酶活性衡量训练效果。评定不同训练方法对提高短道速滑运动员能力的效能，对促进短道速滑项目科学化训练具有重要价值。通过对省、市队短道速滑和未经训练受试对象采用间歇训练法和持续训练法运动4周后观察Na＋，K＋-ATP酶活性变化，研究结果表明：经过短道速滑训练的受试对象Na＋，K＋-ATP酶活性要高于非训练组，并且训练年限越长，Na＋，K＋-ATP酶活性就越高；采用间歇训练法要比持续训练法更容易提升Na＋，K＋-ATP酶活性；动作协调性好的短道速滑运动员Na＋，K＋-ATP酶活性高于协调性差的短道速滑运动员。实验提示：Na＋，K＋-ATP酶活性也可作为短道速滑运动员评定训练负荷和衡量训练效果的敏感指标，短道速滑运动员采用间歇性训练法的训练效果要好于持续性训练法。

| Abstract: | Based on the Na ＋ , K ＋ - ATPase activity with high sensitivity to the training loads, using the Na ＋ , K ＋ -ATPase activity to measure the training effect and to evaluate different training methods will have important value of improving the short track speed skaters＇ performance and promoting the scientific training of short track speed skating. The al skaters from province and city paper investigates the Na ＋ , K ＋ - ATPase activity change of the profession- teams after 4 weeks interval training and lasting training. The results show that the Na ＋ , K ＋ - ATPase activity of training group is significantly higher than the untrained group, and the longer training the higher Na ＋ , K ＋ - ATPase activity. The interval training can more easily increase the ac- tivity than the lasting training, the better a skater＇ motion coordination and the higher his Na ＋ , K ＋ - AT- Pase. The results indicated that the Na ＋ , K ＋ -ATPase activity can be used as a sensitive index to evaluate the skaters＇ training load and training effect. The interval training method has better effect than the lasting training method for the short track speed skaters. |
