【摘要】:目的探讨6周高原训练期间优秀男子赛艇运动员肱二头肌无创微循环相关指标变化特点。方法以10名国家赛艇队优秀男子赛艇运动员为研究对象,分别于高原训练前、高原训练期间、高原训练后3个阶段的每周休息日、晨空腹状态下,采用Peri Flux System 5000激光多普勒血流监测仪对10名运动员肱二头肌进行9次微循环相关指标测试,测试指标包括微循环血流灌注量(MBP)、运动血细胞浓度(CMBC)、运动血细胞平均速度(AVBC)等,测试值包括基础值与加热后值(44℃)。结果 6周高原训练期间运动员的MBP、CMBC和AVBC呈现波浪形变化特点,MBP和CMBC无论是基础值或是加热后值都在第3周上升至最高;AVBC基础值在第3周上升至最高,但第3周AVBC加热后值显著低于第2周和第4周(P0.05)。结论高原训练中无创微循环指标呈现出波浪形的变化特点,MBP、CMBC变化特点主要与高原缺氧及运动负荷的变化有关,尤其是运动负荷的变化,而AVBC则主要与CMBC变化相关;下高原后MBP、CMBC储备能力大小对于运动员运动能力有着重要影响,其可作为检验高原训练是否达到效果的一种方法,且简便、无创。
[Abstract]:Objective to investigate the characteristics of non-invasive microcirculation of biceps brachii in elite male rowers during 6-week plateau training. Methods Ten elite male rowers of the national rowing team were chosen as the research subjects. The weekly rest days before and during the plateau training and the three stages after the plateau training were observed in the morning and fasting state respectively. Peri Flux System 5000 laser Doppler blood flow monitor was used to test the microcirculatory parameters of 10 athletes' biceps brachii muscle for 9 times, including the blood perfusion volume of microcirculation, the concentration of exercise blood cells and the average velocity of exercise blood cells. The measured values include the base value and the heating value of 44 鈩,
