Experiment Research On The Influence Of The 12-week Medium Intensity Fancy Rope Skipping On Obscuring Students Physical Quality

As a sports that fuses dancing,martial arts,music some various forms,integrates fitness,mental health,watching,competition and entertainment,fancy rope skipping is good for teenagers' health.Obscuring students is the part of teenagers in China,whose health is the important problem what our nation concerns.So far,the form of attending exercises in their daily life is simple and the effects are not obvious.Fancy rope skipping not only can enrich their daily life,but has great effects on their fitness,physical function and quality.This paper adapts historical approach,experiment,mathematical statistical method,to divide students in Grade Five and Grade Six in Wuhan City School for the Blind into two groups at random,A and B.Group A is fancy rope skipping interventions,while Group B is the contrast,and based on those two groups,to take a 12-week medium intensity fancy rope skipping intervention experiment.The research on the influence on fancy rope skipping to the students' physical quality,to provide the scientific and reasonable exercise methods and objective basis to promote obscuring students' health and build their exercise habits for life.Result:1.After the intervention experiment,on the fitness of obscuring students,boys in Group A and Group B both have obvious changes in height(P<0.05),weight(P<0.05)and calf girth(P<0.01)after the experiment,while girls have effective changes in weight(P<0.05)and calf girth(P<0.001),but not in the height(P>0.05).And in Group A,the growth rate of calf girth is more obvious than Group B.2.After the intervention experiment,on the physical function of obscuring students,students in Group A,whose lung capacity has more growth rate than Group B after the experiment,and boys in Group A,whose lung capacity has more obvious growth rate(P<0.01),the same as the girls in Group A(P<0.05),and boys in Group B.3.After the intervention experiment,on the physical quality of obscuring students,the change in Group A is more obvious after the experiment.Vertical jump,standing long jump,50-meter race,one-minute rope skipping,50-meter*8 shuttle run,sit-ups,blind stand on single foot in Group A have great change before the experiment(P<0.05);standing long jump,50-meter race,50-meter*8 shuttle run,sit-ups in Group B have great promote before the experiment,but skipping and blind stand on single foot have no obvious change,girls has more rate of vertical jump than boys in Group B.Grip and sit-and-reach of two groups have no obvious change(P>0.05).Conclusions:1.12-week moderate fancy rope skipping can make obscuring students' calf girth enlarge and the weight declining.The rise of boys' height is more obvious than the girls'.2.12-week moderate fancy rope skipping can promote obscuring students' vital capacity.3.12-week moderate fancy rope skipping has great improvement on the obscuring students' upper and lower limbs strength,speed,endurance,flexibility,balance,but not the flexibility.
