多维相位空间法在评定身体负荷对运动员皮肤功能状态作用中的应用

The Use of Method of Multidimensional Phase Spaces to Estimate The Effect from Physical Loadings on Functional State of Athletes' Skin

在皮肤炎症反应当中,微循环障碍是最常见的现象。由于其能够揭示身体在不同的外部环境条件下对身体负荷的适应性反应的基础性工作机制,因而研究从事运动项目人员的微循环也是肌肉活动生理学的重要组成部分。从被损坏的细胞结构中被释放之后,并由于肌肉活动的能量过分消耗,身体负荷的微循环紊乱与代谢产物和生物活性物质的行动紧密相关。本项研究旨在利用多维相位空间法研究身体负荷对运动员的皮肤微循环和经皮氧分压所产生影响的具体特点。根据以往研究,多维相位空间的最大容量出现在男女青年的赛艇和体操项目当中。由此,从事这些项目的运动员比其他项目的运动员以及对照组的男运动员比女运动员具有相对更大的不对称性特征;因此,男女青年运动员的经皮氧分压(背部和前额)具有最为显著的参数,这一参数可用于诊断从事运动时皮肤的功能状态。

Microcirculatory disorders are among the most frequent phenomena, accompanying any skin in flammatory reaction. The study of microcirculation in those who are engaged in sport, represent a relevant part of physiology of muscular work, as it enables revealing the subtle mechanisms laying the basis of a daptive responses of the body to physical loadings, performed in different conditions of external environ ment. Microcirculatory disorder at physical overloadings is related to action of products of metabolism and biologically active substances,being released from the destroyed cell structures and due to exhaustion of energy sources for muscle work. The purpose of the present study was to examine the peculiarities of the influence of multidirectional physical loadings on skin microcirculation and transcutaneous partial pressure of oxygen in athletes using the method of multidimensional state phase spaces. According to the studies, the biggest volume of 5-dimensional state phase spaces is in rowing and gymnastics in boys and girls. Herewith,the ones engaged in these sports have the ones from game sports and the control group substantially bigger indices of asymmetry compared to among boys but not girls. Hence,transcutaneous partial pressure of oxygen （back and forehead） in boys and girls was proved to be the most significant parameter that is to be used in diagnostics of skin functional status at sports classes.
