摘要

目的:本文旨在提供跆拳道运动员的肌肉和音调状态以及脑前和脑血流动力学的特征。材料:102名具有二级运动员至体育硕士志愿资格的运动员参加了研究。研究时运动员的平均年龄为20.90±0.50岁。参与者的平均运动经验为4.15±2.77。对照组由明显健康的同龄年轻男性组成,但不参与体育活动(n=35)。借助头部主要动脉的多普勒超声、神经肌电图和经颅多普勒对肌肉张力、力量和脑血流量的指标进行了研究。结果:本文提供了脊髓运动段肌肉和张力紊乱对脑前和脑血流功能状态影响的研究结果。50%的运动员认为对称躯干肌群的神经传导速度紊乱是肌肉失衡的原因。对肌肉失衡的跆拳道运动员的血流指标分析显示,颈动脉和椎动脉各节段的脑前血管张力典型增加,血流速度梯度变化。运动员脑血流量的减少,特别是肌张力障碍性质的静脉流出,是针对动静脉平衡指标下降的痉挛和缺血性多普勒模式的结果。在谈到跆拳道运动员的陪练活动和比赛导致脑血管功能障碍的发展时,还应考虑轻度创伤性脑损伤。结论:感觉传导和运动传导的差异性紊乱导致传入和肌肉失衡强度的紊乱。在跆拳道运动员中,血管痉挛和血管缺血决定了颈动脉系统线性血流速度的增加和椎基底动脉系统血管的减少,而颈动脉盆地和椎基底血管系统的电阻率指标的增加。相关分析揭示了内脏运动的相关性,证明了区域肌肉系统功能状态对脑血流动力学的影响。通过对跆拳道运动员强直性脊柱炎、强直性脊柱炎肌肉特点及脑血流量的分析,提示有必要纠正椎旁区强直性脊柱炎的不对称性。

Analysis of muscle tone and strength and cerebral blood flow in kickboxers
Purpose: the article deals with providing a characteristic of muscle and tone status as well as precerebral and cerebral hemodynamics in kickboxers. Materials: 102 athletes with the qualification from the Second-class Athlete to the Master of Sport voluntary participated in the study. The average age of athletes at the moment of the study was 20.90±0.50. The average sports experience of participants was equal to 4.15±2.77. The control group consisted of apparently healthy young males of the same age but not involved in sports activities (n=35). The indicators of muscle tone and strength and cerebral blood flow were studied with the help of Doppler ultrasound of the main arteries of the head, electroneuromyography, and transcranial Doppler. Results: the article provides the results of the study on the effect of muscle and tone disturbances in the spinal motion segment on the functional status of precerebral and cerebral blood flow. The disturbances in nerve conduction velocity in the symmetrical groups of trunk muscles are considered as the reason for muscle imbalance in 50% of athletes. The analysis of blood flow indicators in kickboxers with muscle imbalance revealed a typical increase in the tone of precerebral vessels and changes in the gradients of blood flow velocity in various segments of the carotid and vertebral arteries. The decrease of cerebral blood flow in athletes, in particular, the venous outflow of a dystonic nature, is the result of spasmodic and ischemic Doppler patterns against a decreased indicator of arteriovenous balance. Mild traumatic brain injuries should also be taken into account when speaking about the development of cerebrovascular dysfunction as a result of kickboxers’ sparring activities and competitions. Conclusions: Differentiated disturbances in sensory and motor conductivity result in the disturbance of afferentation and muscle imbalance intensity. Angiospasm and vascular ischemia determine the increase in the linear blood flow velocity in the carotid system and the decrease in the vessels of the vertebrobasilar system against the increase in resistivity indicators in the carotid basins and vertebrobasilar system in kickboxers. Correlation analysis revealed visceral motor correlations, which proved the influence of the functional status of the regional muscle system on cerebral hemodynamics. The analysis of tone and strength muscle characteristics and cerebral blood flow in kickboxers indicates the necessity of correcting muscle and tone asymmetry of the paravertebral area.
