Study On The Correlation Between The Cadets Special Physical Fitness And Performance Of 400-meter Obstacle Couese

Obstacle training has always been our army's traditional training program.At present,there are more than ten kinds of obstacles in our army,the 400-meter barrier is one of them.Moreover,this project is an important part of the graduation evaluation and military competition in most military universities.High difficulty,technical difficulty and comprehensive quality requirement are also the biggest characteristics of this subject.The requirements of scientific military training are unceasingly proposed.Military training should be close to actual combat.Under the precondition of training means are unitary and performance has leveled off,it is necessary to further research the400-meter obstaclecourse.In this study,65 cadets were selected as test subjects.The data was obtained through their special sports quality and400-meter obstacle performance.Then,the correlation analysis,factor segmentation and multiple regression analysis were used to analyze the relationship between special sports quality and sports performance.Finally,the multiple regression equation is established to provide some guidance for the next step of scientific training.Research conclusions:(1)The following 9 indexes are significant related to cadets' special sports quality and 400-meter obstacle performance: 100 m race,200 m race,400 m race,800 m race,horizontal bar chinning,standing broad jumping,10 m low body crawling,barbell pressing,and weight-bearing squatting.(2)Specific physical fitness indicators for the 400-meter obstacle are classified as five categories of factors.The sequencing of factor contribution rate as follow: speed factor> speed endurance factor > base strength > explosive power factor > whole body coordination factor.100 m race,800 m race,weight-bearing squatting,standing broad jumping and10 m low body crawling are the typical indicators of physical fitness in5 categories of factors.(3)The prediction model for cadets' special sports quality and400-meter obstacle performance is:400-meter obstacle performance=2.144-0.185×100m race-1.079×standing broad jumping.By the second data verification of cadets' test performance,this model can be used for prediction of cadets' 400-meter obstacle race results.
