Experimental Study Of The Impact Of Different Exercise Load Combinations In Physical Education On Children Health Related Physical Fitness And Emotional States

Continuous recession of children’s health condition has become a focus of worldwide attention. The insufficiency of students’ physical activity and the low-aging developing trends of all kinds of chronic disease have gradually evolved as severe social problems. Children’s health is not optimistic in our country, at the stage of compulsory education, students spent most of his time in the school, so the school should inevitably become the important place of promoting the students’ health development, and then, the school education should probe into this problem, unite they could finally find out more effective methods and measures to promote the students’ healthy growth. The fitness effects reflected in this course, however, don’t achieve desired results in promoting the students’ healthy development. The main problem lies in the lower sports quality embraced in this course, students’ insufficient time of participating in physical exercise, as well as the sports load did not reach to the effective threshold of stimulating students’ healthy grown. The starting point of this paper is to improve the sports quality of P.E., through different combination modes of sports load, explore and analyze the improved effects of students’ healthy physical developments and emotional states in the middle school’ physical education.First of all, based on real case study, this paper pointed out the purpose and significance of the study, put forward the research hypothesis, and determined the research methods and experimental objects; Secondly, reviewed the literatures based on the research status at home and abroad; Third, implemented the related experimental research; and finally, comprehensively analyzed and discussed the research results, drawn a conclusion, as well as put forward the suggestions.Firstly, this study drawn the conclusions by adopting a different health fitness exercises intervention programme to impact on the experimental research of students health fitness and emotional state:(1) health fitness exercises could improve the classroom exercise load, increase the students’ energy consumption, have significant differences compared with comparative classes, and assure the PE exercise load to be maintained in a relatively stable interval;(2) health fitness exercises contributed to improve the students body composition, in those aspect of improving students’ muscular strength, muscular endurance (vigorous intensive class), cardiopulmonary function (MVV is15min vigorous intensive class), flexibility (the class of stand quietly and the PNF stretch method), experimental classes were significantly better than comparative classes. Girls’ flexibility improvements are better than boys; In the aspect of standing long jump, boys’ advancements were higher than girls’;(3) health fitness exercises had positive effective of improving students’ emotional state, which compared with the comparative classes had significant differences in the aspects of improving fatigue, energy, emotional states.Second, in physical education, this study integrated different sustainability movement times and movement intensities, conducted the experiment research on the influence of students’ health fitness and emotional state, drawn the conclusions:(1) The longer the time, the greater the intensity of continuous movement promoted greater improvement in health fitness exercises can improve the PE exercise load, and assured the PE exercise load to be maintained in a relatively stable interval;(2) sustained more than10min vigorous intensity exercise and15min moderate intensity exercise had promoting effects on improving the body composition and muscular strength, muscular endurance. Continuous more than5min moderate intensity exercise might promote the development of heart and lung function. Different sustainability movements had no significant effects on flexibility and strength;(3) continuous15min moderate intensity exercise had better promoting effects on improving students’ emotional state.Third, This study conducted the experimental research on the influences on the students health fitness and emotional states by intervening the different MVPA cumulative times, and drawn the conclusions:(1) the increase of the cumulative MVPA times in physical class could improve the classroom exercise load, and promoted the classroom sports load can be remained in a stable range;(2) the increase of different cumulative MVPA P.E. time had promoting effects on body composition and muscular strength improvement,60%MVPA cumulative time of muscular endurance improved significantly better than that in comparative classes,50%MVPA accumulated time significantly improved cardiopulmonary function, different of MVPA cumulative time had no significant effects on flexibility improvement;(3) more than40%of physical class’ MVPA cumulative time had promoting effects on improving students’ emotional state, in which, more than40%of MVPA cumulative time significantly better than comparative classes on the effects of improving students’ fatigue emotional states, more than60%of MVPA cumulative time significantly better than comparative classes’ girls on the effects of improving girl’s fatigue emotional states.
