| Purpose: The physical fitness of children is closely related to the prosperity of the country.In recent years,the issue of children’s physical fitness has received high attention from various sectors,with the increasing prominence of phenomena such as obesity,myopia,and decreased physical abilities.The primary school stage is an important period for cultivating students’ physical fitness,particularly their agility and coordination.Agility and coordination are the foundation for the smooth participation of the body in sports activities and serve as a guarantee for students to cope with complex environments and handle various emergencies.In recent years,the reform of primary school physical education in Xi’an City has been accelerating,actively promoting the development of freestyle jump rope sports in campuses to improve children’s physical fitness and enhance their enthusiasm for participating in sports activities.Freestyle jump rope is characterized by strong participation and high flexibility,which can cultivate students’ good qualities and achieve the goal of strengthening their bodies,as well as enriching their physical education programs.This article aims to introduce freestyle jump rope into the classroom,explore the impact of jump rope exercises on the agility and coordination of fourth-grade primary school students,and thereby enhance their overall physical fitness.Method: The study adopts research methods such as literature review,expert interviews,field surveys,and data statistics.Two natural classes of fourth-grade students from Xinzhi Primary School in Xi’an City were selected as the research subjects,with 48 students in each class.The students were randomly divided into an experimental group(48 students,28 boys,20 girls)and a control group(48 students,27 boys,21 girls).A12-week experimental intervention was conducted,combining the "National Jump Rope Public Level Exercise Standards" with the primary school physical education curriculum,to intervene with freestyle jump rope exercises.The agility indicators included 20-second repeated horizontal jumps,reaction time,and the Illinois Agility Test,while the coordination indicators included 1-minute freestyle jump rope and quadrant jump test.By comparing the changes in various indicators before and after the experiment,the impact of freestyle jump rope exercises on the physical form,agility,and coordination of fourth-grade primary school students was explored.Results: After the 12-week experiment,data from each group of students were collected and organized.Excel and SPSS 25.0 software were used to analyze the data of various indicators and conduct comparative analysis.The results showed the following:1.Physical form: There was a significant difference(P<0.05)in the height and weight of the experimental group before and after the experiment,while there was no significant difference(P>0.05)in the height and weight data of the control group before and after the experiment.The growth rate of the experimental group was significantly higher than that of the control group(P<0.05).2.Agility: The experimental group showed significant improvement in the20-second repeated horizontal jumps and Illinois Agility Test after the experiment,with a highly significant difference(P<0.01).There was no significant difference(P>0.05)in reaction time.The control group showed a significant difference(P<0.05)in the20-second repeated horizontal jumps before and after the experiment,while there was no significant difference(P>0.05)in reaction time and the Illinois Agility Test.There were significant differences(P<0.05)in reaction time and the Illinois Agility Test between the experimental and control groups,while there was no significant difference(P>0.05)in the 20-second repeated horizontal jumps.3.Coordination: There was a highly significant difference(P<0.01)in the quadrant jump test of the experimental group before and after the experiment,and a significant difference(P<0.05)in the 1-minute freestyle jump rope.The control group showed a significant difference(P<0.05)in the quadrant jump test before and after the experiment,while there was no significant difference(P>0.05)in the 1-minute freestyle jump rope.Conclusion:1.After participating in freestyle jump rope training,the students in the experimental group showed significant improvement in agility and coordination indicators compared to before the experiment,with P<0.05.2.The experimental group showed significant improvement in various agility and coordination indicators compared to before the experiment,indicating that the impact of freestyle jump rope on agility and coordination is more pronounced.3.After the experiment,the scores of the experimental group in the sports tests showed significant improvement compared to before the experiment,with P<0.05.Therefore,freestyle jump rope exercise is in line with the characteristics of adolescent growth and development.It is feasible and effective to carry out freestyle jump rope practice in primary school physical education. |
