To observe the TcPO2、TcPCO2 and functional status changes and to discuss the relations between TcPO2、TcPCO2 and functional status of elite male rowers. Method: 8 male lightweight rowers of Chinese National Rowing Team were selected as the subjects. According to the training plan, March 5-April 2 was the first phase (before the Spring Championships) and April 9-28 was the second phase (before the World Cup). In the two training phases, blood samples were taken every Monday morning before eating breakfast. Microcirculation indices were collected with PeriFlux 5000 system on the same day. The indices included TcPO2, TcPCO2, testosterone(T), cortisol(C), blood urea nitrogen (BU), creatine kinase(CK), hemoglobin(Hb) and red blood count(RBC). Result: In the two training phases before the World Cup, Hb and RBC reduced obviously in the first phase and increased in the second phase. BU and CK increased significantly at the end of the first phase and then stayed stable in the next phase. T decreased in the first phase and increased to a higher point in the second phase .T/C kept steady. TcPO2 had the same variation tendency as Hb. The correlation coefficient between TcPO2 and Hb in the second week of the second phase was -0.882 (P<0.05). The correlation coefficient between TcPO2 and BU was 0.943 (P<0.01). Conclusion: The athletes? ability of carrying oxygen and the total functional state are good before the World Cup. There is a correlation between TcPO2, TcPCO2 and functional state indexes, with almost the same changing trend. To a certain extent, TcPO2 and TcPCO2 can be used to evaluate athletes? functional status. |
