The Influence Research Of Winter Train Of Excellent Modern Pentathlon Women Athlete's Body Composition

Objective: By studying the national modern pentathlon during winter training female athletes body composition change,discuss and analyse the winter training of national modern pentathlon female athletes body composition and the influence of concrete action,in order to further improve the level of training modern pentathlon coaches and athletes of the competitive level to provide some theoretical reference basis,and relevant for the modern pentathlon after lay the foundation for further studies.Methods: The research object of this topic for the national team for the London Olympic Games cycle training team for the first time,a total of 11 women athletes.Among them,is the defining standard of excellent athletes level and above.To observe the effects of winter training for the athletes body composition.Time for two months,follow international training arrangement,time: 2014.12 to 2015.3.This experiment in training before and after training all in the same experiment index collection,and are completed by the same researchers use the same instrument.Training before the tests a week before the start of the training at 8:00 in the morning-around 11:00,fasting without exercise testing;After the training test also at 8:00 in the morning-around 11:00.Site training center in Beijing sport university.Results:(1)Body fat percentage of modern pentathlon athletes training before the test result is 18.71,after two months of winter training,test results is 17.18,down 1.53 before the training,with significant difference(P < 0.05).(2)Modern pentathlon in female athletes training muscle weight is 45.04 kg,after two months of winter training,test results is 46.66 kg,an increase of 1.62,before the training has very significant difference(P < 0.01).(3)The modern pentathlon female athletes training playmaker hip ratio(WHR)is 0.76,after two months of winter training,test results is 0.75,training with the test results of the training precursor fat percentage statistical differences(P < 0.05),has the significance.(4)The modern pentathlon female athletes training before chest periphery is 86.43 cm,after two months of winter training,test results is 87.73 cm,training has significantly increased(P < 0.05);Hip circumference after training to reduce the trend,but not significant difference;Thigh after peripheral training compared with training increased by 1.4 cm,with significant difference(P < 0.05).Outer upper arm training before is 26.61 cm,27.67 cm after training,increased by 1.06 cm,with significant difference(P < 0.05).(5)The modern female athletes training before the weight is 60.62 kg,after two months of winter training,test results is 57.15 kg,training before and after training weight reduced 3.47 kg,compared with very significant difference(P < 0.01).Body mass index(BMI)before the training of 21.31 kg/m 2,after the training was 20.27 kg/m 2,compared with before the training has a tendency to reduce,with significant difference(P < 0.05).Conclusion:(1)Winter training athletes can improve lipid metabolism,and improve the activity of protease,fat decomposition and utilization of the development of muscle strength and improve the modern pentathlon female athletes speed and performance has a positive role.(2)The winter training can effectively increase the modern pentathlon female athletes muscle weight,improve muscle strength,stretching and flexibility,to prevent muscle atrophy,decreased muscle mass,muscle ageing,etc have a positive effect.(3)The winter training can effectively reduce the modern pentathlon female athletes waist,hip fat,promote the decomposition of the body's metabolic energy,increase energy consumption,reduce weight.(4)The winter training can effectively improve the modern pentathlon female athletes upper limb and lower limb power by its power,the weakness in China's modern pentathlon project can improve the running and swimming have certain effect.
