| Physical education classroom exercises are an effective way to improve the physical fitness of the vast majority of primary and middle school students in China and obtain better athletic performance.How to innovate,enrich scientific practice methods and implement them effectively is a problem that most grassroots physical education teachers need to solve urgently.The research purpose of this research is to explore whether the 10-minute training of each class in the normal physical education class can ensure sufficient exercise load and improve students’ rapid strength.By comparing the effects of fun class training with traditional physical education teaching,In order to quickly improve the rapid strength level of the first grade students.The research method of this thesis is mainly based on experiments.The experimental plan is adjusted by sorting out relevant literature materials and expert interview materials.60 seventh-grade students from N Middle School in Nanchang City are used as experimental subjects,and they are randomly divided into experimental group and control group for nine weeks Physical education teaching experiment.The experimental subjects have three 45-minute physical education classes every week.On the basis of completing the main textbook teaching content,the experimental group students will practice running,jumping,physical strength,rapid response and sensitivity,and large group games in the physical education class.The 10-minute "fun lesson practice" of the control group used the commonly used quick strength practice methods as the practice content.After the experiment,the statistical index changes of the two groups were compared,and the following research results were obtained after analysis:(1)After 9 weeks of experimental intervention,after a paired sample T test,it was found that the rapid strength level of the experimental group and the control group increased significantly(P<0.05).Boys in the experimental group perfnrmed better than those in the control group,and the difference between the two groups was statistically significant.Girls in the experimental group performed better than those in the control group,and the difference between the two groups was significant.(2)In the experimental group,boys’ standing long jump,50-meter running,and forward throwing solid ball,the performance of these three test indicators have extremely significant differences before and after the experiment(P<0.01);reflecting the students’ fast strength quality In the five tests,the difference in differences.(3)The students well in the three test items of standing long jump,50-meter run and vertical jump,but the control group had no significant difference in the performance of forward throwing solid ball between boys and girls before and after the experiment.(P>0.05);Analysis conclusion:(1)The application of fun lesson practice in regular physical education can develop the rapid strength of the first grade students,including the rapid strength of speed and the rapid strength of strength.Improve other physical fitness while promoting the rapid strength development of junior one students.(2)The traditional physical education classroom teaching emphasizes that the rapid contraction of muscles can develop the explosive power and jumping ability of the lower limbs of the students,but it lacks the ability to respond to rapid strength.At the same time,there are fewer exercises for the core and upper limb muscles.(3)The form and content means of the fun lesson practice to develop the rapid strength of the first year students should conform to the characteristics of the growth and development law.Reasonably arrange physical education activities and skillfully use competitions to encourage junior high school students to engage in interesting and efficient physical exercises in group sports. |
