The Study On The Change Features Of Noninvasive Microcircu-Iation Indicators And The Relationship,Between Features And Functional Status Of Elite Man Rower During Six Weeks Of Altitude Training

Objective:The study of noninvasive indicators of microcirculation characteristics of the change of normal physical indicators and trainning load structure and the explore of the relationship among the relative indicators’ change of noninvasive indicators of microcirculation, trainning load and the state of athlete’s physical function are determined to improve the application of noninvasive indicators of microcirculation in the supervision of the state of rowing athlete’s physical function and hence to expend the scale of the application of noninvasive physical function supervision indicators in the monitor of athlete’s physical function. Futhermore,it could provide references and exemples for enhancing current quality of the supervision of athlete’s physical function.Method:The whole study was divided into two parts, the experiment one and experiment two.(1):12 male elite rowers were testd in different muscles(upper limb biceps, gong radial muscle and lower limbs, gastrocnemius quadriceps)by using Peri Flux System5000.The index mainly include microcirculatory blood perfusion, concentration of moving blood cells, average velocity of blood cells and skin temperature, and MBP= CMBC* AVBC/100. The test environment for indoor temperature(25±3) ℃, humidity 45.0% to65.0%, test values include base value and site after heating(44 ℃), and the heating indicators before and after the difference as the index of microvascular largest reserve capacity, here in after referred to as the reserve capaciTy.Make the monitoring sites of the first experiment study as the sites for testing athletes in the second experiment. The specific research method isdividing altitude training into before, during and after three stages. The first stage is one week before altitude training. On the morning of January 12 th,we had a noninvasive test for 10 athletes with Peri Flux 5000 Laser Doppler blood flow monitor System who were on an em- pty stomach condition. At the same time routine function index test by fing- ertip blood was carried,totally measuring one times; the second stage(2014.1.17-2014.2.27) is for 6weeks altitude training. Each index test method is as above and we measured once every 7 days, a total of measuring 6 times; the third stage is 2 weeks after altitude(2014.1.28- 2014.3.12).The test m- ethod is as above, also for every 7 days of 1 measurements, a total of 2 measurements; The entire altitude training stages were tested 9 times, at the same time fingertip blood for9 times. Microcirculation test index is the same as experimental one and the finger tip blood test indexes include blood rout- ine, blood urea(BU) and serum creatine kinase(CK). In addition, through venous blood to the athletes during key cycles corresponding time period, we carried testosterone(T) and cortisol(C) test and then make comprehensive diagnosis for the athletes’ Physical Function.Result:(1) The comparison of the different parts of the muscle MBP Base value:biceps > gong radial muscle > quadriceps muscle >gastrocnem-ius, biceps and significantly higher than that of humerus oar and quadriceps muscle(P < 0.05) and calf(P < 0.01);After heating value and add difference before and after the heat: gong radial muscle > biceps > quadriceps muscle>gastrocnemius muscle, and the radial, biceps brachial were significantly higher than that of gastrocnemius(P < 0.05).(2) The change of MBP, CMBC, AVBC during altitude training Altitude training week 1 MBP, AVBC fell, while the CMBC was increased;After a few weeks each index present wave change trend, MBP, CMBC peaked in the third week, the MBP reserve capacity significantly plateau 2 weeks 3 weeks, 5 weeks(P < 0.05) and 4 weeks(P < 0.01), the ability of CMBC reserve 3 weeks is significantly higher than 2 weeks(P < 0.01);4 weeks,5 weeks MBP, CMBC will gradually decline,but the obvious rise, 6 weeks after the plateau MBP changed little, and above the levelof the plateau training before, CMBC after the plateau has increased, and above the level of the plateau before.AVBC peaked at 6 weeks, and AVBC reserve capacity is significantly higher than 6 weeks 5 weeks(P < 0.05) an-d 1 week, 3 weeks(P < 0.01), after the next plateau AVBC declined, and below the level befor e the plateau.(3)The change of Hb, BU, CK during altitude training Altitude training week 1 each index 1 week before both the plateau was increased, but did not have significant difference(P > 0.05);2, 3, 4 weeks Hb have been gradually rise, and reached the maximum of altitude training, 4weeks after athletes Hb have been gradually declining trend, but 2 weeks after the plateau athletes Hb was increased, and significantly higher than altitude training before 1week(P < 0.05);BU 2 weeks, 3 weeks have been gradually declining trend, but 4 weeks increased significantly, and achieve the maximum of the altitude training, followed by BU athletes have been gradually declining trend,but 2 weeks after the plateau 1 week after the plateau was increased;CK 2 weks athlete fell, but 3 weeks increased significantly,in subsequent weeks showed significant wavy change trend, CK first rise-a fter the fall, after the plateau and slightly above the level of the plateau before.(4)The change of T, C and T/C of key weeks during altitude training In key weekly athletes T present the features of the “∧” type,enter the altitude training athletes T have been gradually rising trend, among them 4 weeks, 6 weeks were significantly higher than that of plateau training before 1week 1 week and altitude training(P < 0.05);2 weeks after the plateau T apparent decline in athletes, and significantly lower altitude training 4 weeks,6 weeks(P < 0.05), but it is still higher than 1 week before level altitude training;C also presents the basic change characteristics of “∧” form, enter the altitude training athletes C have been gradually rising trend, but 2 weeks after the plateau athletes C decreased obviously, and significantly less than4 weeks(P < 0.05) and 6 weeks(P < 0.01);T/C change trend and T are basically identical.(5)the correlation between MBP, CMBC, AVBC reserve capacity and Hb,BU, CK Function of microcirculation blood flow reserve capacity with the conventional indicators present a certain relevance, among them and is positively cor related to the Hb(R = 0.273, P > 0.05), and BU there is negative correlation(R =-. 561, P < 0.05), and negative correlation with CK(R =-. 161, P >0.05);There are correlated to the blood concentration of reserve capacity and Hb(R = 0.545, P < 0.05), is positively correlated with BU(R = 0.145, P >0.05), CK at the same time there are positive correlation(R = 0.529, P <0.05);Blood velocity reserve capacity with the conventional indicators also presents the correlation function, blood velocity of reserve capacity and is negatively correlated to the Hb(R =-. 350, P > 0.05), and BU there is negative correlation(R =-. 419, P < 0.05), and negative correlation with and CK(R=-. 599, P < 0.01).Conclusion:(1)Due to differences in special training load structure, cause the man rowing athletes upper limb muscles MBP values significantly higher than that of lower limb muscles, especially the reserve capacity, so in order to make the microcirculation index monitoring results more representative, rowing athletes of MBP and related indicators monitoring should be selected when upper limbs on the same muscles and anatomical sites of the same space;(2)The indexs of MBP, AVBC reserve capacity show the characteristiccs of "W",and CMBC reserve capacity show the characteristiccs of converse "W".The characteristic of MBP CMBC reserve capacity changes mainly associated with the change of plateau hypoxia and exercise load,es pecially closely associated with sports load structure, while AVBC changes mainly based on the size of CMBC;(3) As a whole, the function of altit-ud e training athletes in good condition, no obvious fatigue accumulation, illustrate the coaches control accurateofthe plateau training training rhythm;However, as the altitude training gradually a fourth, fifth week function state, has a certain fatigue accumulation.(4)Induring altitude training microcirculation index to present a certain correlation with various functional indices and show a similar trends,especially the MBP reserve capacity s closely related to functional status,it can as an important auxiliary index of reflectcing the fatigue state of the athletes.
