Study On The Character Of Microcirculation Indexes For Athletes Of Different Sports Events

Objective：To discuss the character of biceps brachii’s and quadriceps femoris’microcirculation index such as blood perfusion (PU), the concentration of movingblood cell(CMBC), the movement velocity of blood cell (V), the pressure of oxygen(tcpO2) of different sports, different level athletes. To explore the biochemicalindicators which is related to the brachii’s and quadriceps femoris’ microcirculationindex. In order to find the no innovation index of diagnose functional state fromtheory and practice and provid the services to improve the training quality.Methods：（1）Subjects and Groups：The subjects were consisted of101athletes ofShanghai city sports teams and20ordinary people without professionaltraining.Among the athletes, there were40rowers,24Yachtsman,27kayakers, and10short-distance cyclists.There was a total of64male athletes and37female athletes.（2）Testing Arrangements：With the room temperature kept25±3℃, air humiditykept45.0%-65.0%,the subjects were studied by using PeriFlux5000on the bicepsbrachii’ and quadriceps femoris’ resting microcirculation.The athletes adjusted0.5to1days after the short training period can be tested. The probe of the PeriFlux5000should be heated to44℃without air humidity changed.（3）Test Specifications：①Microcirculation indexes: the biceps brachii’s and quadriceps femoris’ bloodperfusion (PU), the concentration of moving blood cell(CMBC), the movementvelocity of blood cell (V), the pressure of oxygen (tcpO2). PU、CMBC、V should betested before and after the probe heated. biochemical indicator:Hemoglobin(Hb),serum ferritin (SF),testosterone (T), cortisol (C), Epinephrine (EPI),norepinephrine (NA), endothelium-derived relaxing factor (EDRF), vascularendothelial growth factor (VEGF).（4）Statistical Methods: All data were usedSPSS17.0statistical software and Microsoft Excel2003software analyzed; resultswere said by mean±standard deviation (M±SD). Considered p<0.05for a significantdifference, p <0.01for a highly significant difference.Results：（1）Comparison of different sports athletes’ microcirculation indexesRowing athletes’ PU was highest, their biceps brachii’s PU and quadricepsfemoris’ PU were higher than the lowest sports(short-distance cycle, sailing)73.0%（p<0.05），133.3%（p<0.05）. The rowing athletes’ changing rate of PU forquadriceps femoris was lower than sailing athletes’333.9%（p<0.05）. Canoe andkayak athletes’ changing rate of CMBC for biceps brachii was lowest, but had nosignificant difference with other sports athletes’. Canoe and kayak athletes’ changingrate of V for biceps brachii was higher than other sports athletes’. In addition, V ofshort-distance cycle athletes was in the low level.（2）Comparison of different levels athletes’ microcirculation indexesThe microcirculation indexes of different levels athletes were different. Themaster athletes’ changing rate of PU, V for biceps brachii was higher than Grade Bathletes’168.0%,118.1%; the master athletes’ changing rate of PU, V for quadricepsfemoris was higher than the lowest groups(Grade B athletes and Grade A athletes)223.0%,121.0%.The master athletes’ tcpO2was higher than the other groups, too. Grade A athletes’ PU, V was good; Grade B athletes’ changing rate of PU and thechanging rate of V was lower than other groups, their tcpO2was bad, too.（3）Relationship between microcirculation indexes and biochemical indexes fordifferent levels athletesThe sports athletes whose EDRF was higher, their tcpO2for biceps brachii andPU for quadriceps femoris were lower, but The sports athletes whose SF was higher,their tcpO2for biceps brachii was higher, too. The sports athletes whose VEGF washigher, their changing rate of PU for quadriceps femoris was lower, whose EPI washigher, their changing rate of CMBC for biceps brachii was lower, whose T washigher, their V for biceps brachii was lower, too. The sports athletes whose C washigher, their PU for biceps brachii, CMBC for quadriceps femoris was higher, whoseNA was higher, their changing rate of V for biceps brachii was higher.Conclusion:（1）Microcirculation indexes were different among athletes of different sports. Therowing athletes’ PU before heated was highest, but the reserve capacity of PU forquadriceps femoris was worst. The rowing athletes’ reserve capacity of PU forquadriceps femoris was highest. Canoe and kayak athletes’ reserve capacity of CMBCwas worst; the reserve capacity of V was best. The blood flow velocity ofshort-distance cycle athletes was lowest. In addition, athletes’ ability of the bloodcarrying oxygen for biceps brachii was better than the normal control group.（2）Microcirculation indexes were different among athletes of different levels. Themaster athletes’ microcirculation of PU reserve capacity and V reserve capacity werebest, the ability of the blood carrying oxygen was best, too. Grade A athletes’microcirculation of PU before heated and V before heated were highest. Grade Bathletes’ microcirculation of PU reserve capacity and V reserve capacity were worst,the ability of the blood carrying oxygen was worst, too.（3）The microcirculation indexes for athletes of different sports had a certainrelationship with VEGF,EPI,T,C,NA and SF.
