摘　　要：目的:探讨长期有氧耐力训练对我国不同组别赛艇运动员肱二头肌微循环血流储备能力的影响,为我国赛艇队运动员身体机能状态监控数据标准的建立及微循环血流储备能力数据库的建立提供一定的依据。方法:77名国家队不同组别赛艇运动员及24名不同性别的普通健康国人(男、女各12名)运动员晨起空腹状态下使用Peri Flux System 5000激光多普勒血流仪对右侧肱二头肌微循环血流灌注量(MBP)及相关指标进行无创测试,且所有受试者测试位点均为右侧肱二头肌同一空间的解剖位点,无明显的空间差异;所有运动员测试均在其机能状态相对比较稳定的情况下进行,普通人测试均在健康状况良好的情况下进行,测试值包括基础值和加热后值(44℃),以加热前后MBP的差值作为微循环血流储备能力。结果:女子公开级(198.97±98.81)>男子公开级(183.45±64.31)>男子轻量级(151.01±65.96)>女子轻量级(140.53±43.22)>普通男性国人(127.21±56.38)>普通女性国人(103.54±33.41),各组运动员均显著高于普通健康国人(除女轻组与普通男性国人比较),但不同组别运动员之间均无显著性差异(P>0.05)。结论:1长期的耐力训练可提高赛艇运动员微循环血流储备能力,尤其是公开级赛艇运动员;2我国公开级赛艇运动员肱二头肌微循环血流储备能力正常值应在160以上,轻量级赛艇运动员应在120以上,且不同性别运动员之间无明显差异,若训练中明显低于正常值,则表明运动员机能状态较差且处于运动性疲劳状态。Objective： To investigate the effect of chronic endurance exercise on microcirculatory reserve capacity of biceps brachii in Chinese rowers and provide a certain basis for the date standard foundation of monitoring of functional status and the foundation of database of reserve capacity of blood of Chinese rowers. Methods： Empty stomach in the morning,77 rowers from different groups and 24 common health people were noninvasive tested by using Peri Flux System 5000,the test indexes include the microcirculatory reserve capacity and other related indexes of biceps brachii. The test sites of all athletes were the same space in biceps brachii of the right side of body,there was no space differences of all athletes. All athletes were tested in the relatively stable functional status,common people were healthy. The test value included basic values and heating values,put the before and after heating of microcirculatory blood perfusion（ MBP） as the microcirculatory reserve capacity. Results： Heavyweight female（ 198. 97 ± 98. 81） 〉heavyweight male（ 183. 45 ± 64. 31）〉 lightweight male（ 151. 01 ± 65. 96） 〉lightweight female（ 140. 53 ± 43. 22） 〉common male people（ 127. 21± 56. 38） 〉common female people（ 103. 54 ± 33. 41）,the microcirculatory reserve capacity of each group athletes were higher than common people,except the comparison between lightweight female and common male people,and there was no significant difference among the different group athletes. Conclusion： Chronic endurance exercise can improve the microcirculatory reserve capacity of rowers,especially the heavyweight rowers; the normal value of microcirculatory reserve capacity of heavy weight rowers should be more than 160,and lightweight rowers should be more than 120. There was no significant difference among different sex athletes,if the value of microcirculatory reserve capacity is significant lower than normal,it shows that athletes are in the state of fatigue.
