| Objective: Physical function of athletes is an important factor to affect its competitive ability.The physiological and biochemical index of national modern pentathlon team female athletes in the winter training during the tested and deep analysis and research,Truly reflect China's modern pentathlon team in winter training during the women's functional state of athletes to adapt to the training load of the actual situation to influence on the physical function of the athletes from the analysis of coaches,sports load arrangement and the body of exercise load reaction.For further guidance to prepare for the training and improve the athlete athletics level provide a reference,and explore a set of suitable for China's modern pentathlon team during the winter training of the complete system of training mode,which lays a theoretical foundation for the development of China's modern pentathlon team of women's sports.Methods: Select the five modern national team preparing for the London Olympic Games cycle for the first time players as the research object,a total of 11 female athletes.Among them,the definition of elite athletes is the first level and above;The winter training before and after winter training athlete's heart rate(HR),hemoglobin(HB),serum creatine kinase(CK),blood urea(BUN)and maximal oxygen uptake(VO2)index were collected and analyzed respectively.The collection of the experimental index was accomplished by the same instrument.Blood sampling time was from 6:30 to 6:00 on Monday morning,in the athletes' fasting,quiet state,the amount of blood or elbow blood test.Results:(1)The modern pentathlon athletes heart rate training before the test results 54.0 +5.01 and after winter training test results for 49.50 + 560.After the winter and winter before compared to a decrease of 3.5,with significant difference(P<0.01).(2)The Modern Pentathlon Women's players during the winter training of hemoglobin for 7.36 g / dl 133.6 + and after winter training muscle weight for hemoglobin is 14.49 + 8.74g/dl,rise the 11.3 g / dl,after the winter,compared with before winter training,with very significant difference(P < 0.01).(3)Modern Pentathlon Women Athletes in the serum creatine kinase before winter training test results to 181.6 + 102.7g/dl and after winter training test results for 79.5 + was 25.98 g / dl.Before winter and winter compared to reduce the 102.1 g / dl,there is a statistically significant difference(P < 0.05),with significant changes;after winter training,modern pentathlon athletes blood urea by 7.63 + 0.86 ng / dL to decline to 5.12 + 0.60ng/dl,dropped 2.51 ng / dl.There was a significant difference between the test results and the winter after winter training before blood urea(P<0.05),with significant changes.(4)Modern Pentathlon Women players during the winter training of maximal oxygen test results to 4.602 + 12.67 L / min,winter after maximal oxygen uptake test results for 63.25 + 5.11 L / min,after winter training before the winter training,maximal oxygen uptake test results compared to an increase of 17.23 L / min,with very significant difference(P < 0.01);before the winter training,blood lactate test results for 10.46 + 2.32 mmol / L,after winter training test results for 8.75 + 3.16 mmol / L,decreased significantly,compared with before winter training have very significant difference(P < 0.01)Conclusion:(1)Winter reduced five modern women athletes heart rate,improve cardiac function reserve.(2)Winter can be athletes hemoglobin content increased,improve the oxygen transport capacity,for athletes in the modern pentathlon in the technology of play has a key role.(3)Winter training reduced the content of modern pentathlon athletes CK and bun,the cardio-pulmonary function improved obviously,oxygen ability has been improved obviously.(4)After winter training VO2 max index increased,BLA index decreased significantly and improve the oxygen supply to the proportion of modern pentathlon athletes,the cardiopulmonary function and muscle using oxygen ability enhancement. |
