[Study on the biceps brachii microcirculation blood flow reserve capacity of the Chinese rowers].

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.,Empty stomach in the morning, 77 rowers from different groups and 24 common health people were noninvasive tested by using PeriFlux 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.,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.,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.
