Study On The Quality Of Straight Ride In Cheerleading

Comepetitive cheerleading devide into dance and cheer.In competitive rule of cheerleading,the total score of team cheer routine is 100 points,in which Basket Toss is 15 points.Thus it can be seen Basket Toss is one of the most important and typical skill in cheer.Straight Ride is the most basic basket toss in cheerleading.In this paper,the indexes of evaluating movement quality and typical special physical quality were selected by expert interview method(a total of 10 people).The straight ride of 25 groups were videotaped and the typical special physical qualities of 19 subjects were measured by measuring method.Mathematical statistics(frequency statistics,linear regression analysis,factor analysis and grey correlation degree analysis)are used to clarify the action and technology of straight ride.The evaluation standard of straight ride quality is constructed and the correlation between special physical quality and action quality is analyzed and studied.The purpose of this paper is to make up for the shortcomings of the theoretical research of straight ride,to provide theoretical reference for the training of straight ride,and to guide the relevant training practice,so as to improve the quality of action.The results show that:(1)the straght ride can be divided into five stages: preparation,sinking,upthrow,air modeling and cradle.The technique of each movement stage should follow the basic principle of maximization of throwing power and prevention of sports injury.(2)Height,horizontal displacement and air modeling can be used to evaluate the quality of straight ride,each index has its own rating level.The influence of the three factors on the quality of straight ride is: height > air modeling > horizontal displacement.If the full score is 15.0,the score of the straight ride is y=1.1x1+0.9x2+ x3(x1 as the height score,x2 as the horizontal displacement score,x3 as the air modeling score).The height full score is 5.5,the horizontal displacement is 4.5,and the air modeling is 5.0.(3)In order to improve the quality of straight ride,the ratio of training contents of base and back spot is: special speed strength of upper and lower limbs > core strength > coordination quality.the ratio of training contents of flyer is: reaction ability > core strength > weight loss > lower limb speed strength > upper limb strength.Strengthen static training means while training core strength.
