摘　　要：【目的】从运动员与体育木地板的相互作用关系出发,研究运动员运动生理生化指标与体育木地板运动功能的相关性,构建一种基于运动员运动生理生化指标比较体育木地板运动功能性的方法。【方法】选用3种典型结构型式(双层龙骨结构、单层龙骨结构和可拆装式结构)体育木地板,在设定的2种运动强度(心率为每分钟110~120次的低强度运动和170~180次的高强度运动)和固定运动模式下,采集运动员运动相关生理生化指标,包括即时血乳酸、主观感觉评价和血清肌酸激酶等,利用方差分析和非参数分析方法判定检测值之间是否存在显著差异。【结果】1)固定运动模式条件下,体育木地板结构型式和运动强度对运动员的即时血乳酸具有显著影响,低强度运动条件下,双层龙骨结构体育木地板上运动员的即时血乳酸明显高于其他2种结构型式体育木地板;2)采用岗奈尔·鲍格主观体力感觉等级表评定运动员完成规定运动后的主观感觉,在低强度运动条件下双层龙骨结构体育木地板上运动员的主观感觉最累,体力感觉等级高于其他2种结构型式体育木地板;3)固定运动模式条件下,体育木地板结构型式和运动强度对运动员血清肌酸激酶的影响不明显。【结论】运动员运动生理生化指标与体育木地板运动功能间具有相关性,基于运动员运动生理生化指标比较体育木地板运动功能性的方法是可行的。该方法是在低强度运动条件下,运动员在不同结构型式体育木地板上完成连续跨栏运动,检测运动员的即时血乳酸和主观感觉,采用方差分析方法或非参数Kruskal-Wallis检验分析即时血乳酸,并判定不同结构型式体育木地板上运动员即时血乳酸之间是否有明显差异,结合主观感觉数值从大到小可对不同结构型式体育木地板的功能性进行排序。【Objective】 The relativity between physiology and biochemistry indexes of athletes and functional property of wooden sports flooring was carried out on the basis of the interactions between athletes and wooden sports flooring. A method has been established about comparing the functional property of wooden sports flooring through sports physiology and biochemistry indexes. 【Method】 Three typical different samples of wooden sports flooring with different structures (the structure with double keels, the structure of single keel and the removable structure) were chosen as the tested objects. The exercising process was carried out under the same exercise pattern and two levels of exercise intensity (low exercise intensity when heart rate arriving 110-120 beats per minute, and high exercise intensity when heart rate arriving 170-180 beats per minute). The relative physiology and biochemistry indexes of the athletes were tested, including the immediate blood lactate concentration(BLC), Borg ratings of perceived exertion(RPE) and serum creatine kinase(CK). Then, the ANOVA analysis and non parametric analysis were used to judge whether there is a significant difference between the test values or not. 【Result】 1) Under the conditions of fixed exercise pattern, the structure of wooden sports flooring and the exercise intensity both have significant influences on BLC of the athletes. The BLC values of the athletes completing the fixed exercise on the wooden sports flooring of the structure with double keels are significantly higher than the values gathering from the other two samples, under the low exercise intensity. 2) The Borg ratings of perceived exertion(RPE)method is used to evaluate the status of athletes after completing the fixed exercises. The results showed that the athletes on the structure with double keels subjectively feel most tired under the low exercise intensity. The RPE results of this structure are obviously higher than those of the other two samples. 3) Under the conditions of fixed exercise
