EFFECTS OF JUMP ROPE TRAINING ON EXPLOSIVE POWER IN BADMINTON PLAYERS

ABSTRACT Introduction: After implementing the national fitness program in China, badminton has attracted the participation of the general public, consolidating itself as a national weight loss program. Objective: Study the effects of jump rope training on explosive power in badminton players. Methods: Thirty-six young athlete volunteers were selected and divided into groups A and B to conduct an intervention study on jump rope training. All students’ intensity and exercise time were strictly controlled to ensure the validity of the results. Validated fitness tests, including the endurance index, were used to check the impacts of training. Results: There was no significant difference in endurance and speed between students in groups A and B before the experiment (P>0.05). The endurance and speed of students in groups A and B after the experiment were significantly different (P<0.05). Conclusion: Adding jump rope training to badminton physical training can effectively improve the explosive power and speed in the lower limbs of its athletes. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.


INTRODUCTION
Since the implementation of the national fitness program in China, badminton has attracted the active participation of the general public with its own unique charm.Relevant surveys have found that among many sports, badminton is the second most popular sport following "brisk walking". 1Specifically, badminton is a competitive sport.Therefore, more and more people are learning badminton.How to let badminton learners learn badminton in the shortest time, and mastering the correct technical movements is the key point that badminton teachers need to understand and master. 2 It is very important for a good badminton player to have good strength qualities, in badminton, athletes use footwork displacement and perform various technical movements on the court need strength quality as the basis. 3B Zgür pointed out that in badminton, a player's lower body explosive power level directly affects his displacement speed and ability to change direction on the court, therefore, explosive power plays an important role in badminton performance. 4Olesen J S pointed out that the explosive power of lower limbs in badminton is mainly manifested in the fast movement of footwork on the court, and the fast movement of footwork on the court is the core ability of badminton. 5A Gómez, selected 27 undergraduate badminton athletes to conduct experiments to explore the effect of vibration training on the explosive power of lower limbs, the experimental subjects were divided into three groups: 30Hz, 45Hz and the control group, respectively, for 9 weeks of training, the study showed that the two groups using vibration training were better than the control group in terms of lower body explosive power and specific movement speed, among them, the 45Hz vibration training has the greatest improvement on the explosive power of the lower limbs. 6Passos P conducted a 6-week centripetal combined eccentric strength training for 21 badminton players who reached the national second level, according to the conclusion, it is pointed out that both the fast group and the slow group have ideal effects on improving the strength of the lower limbs, and the fast group has better effects on the improvement of the two special abilities of badminton four-point touch and standing long jump than the slow group. 7n conclusion, there are few studies that have investigated the effect of string interference on the lower extremity of tennis players on the lower extremity of soccer players, and verify its training effect on the special ability combined with the footwork test, in order to provide more reference for the application of rapid stretching compound training in badminton training.

METHOD Documentation method
Through literature search, the conference reports related to rope skipping and badminton training were consulted on academic journals such as CNKI, VIP, and Wanfang, dissertation and other materials; Access to specific books related to research through university libraries and libraries; Enter keywords such as "speed", "endurance", "skip rope", "badminton training" and other keywords in Baidu Academic website and Google Scholar to search.The above-mentioned relevant data are sorted and analyzed, and the reading research is carried out on this basis, which provides a solid theoretical basis for this research. 8

Experimental method
Subjects: 36 badminton students from a university specializing in badminton, all the students who participated in the test have studied badminton special courses for more than one year, and the badminton foundation is very solid.All students were divided into Group A and Group B by lottery, with 18 students in each group.Among them, there are 11 boys and 7 girls in group A, and 11 boys and 7 girls in group B, the proportion of male and female students in the two groups is balanced.The students in group A were trained in accordance with the previous badminton training methods, and the students in group B were trained in the pattern skipping training method.

Statistics method
The whole experimental process is divided into different stages, and statistical analysis is carried out on the training progress and training data of athletes each time, and finally a conclusion with high accuracy is drawn. 9

Control of experimental related factors
In the process of this experiment, the interference environmental factors that may appear outside are strictly controlled, and all the staff who participated in the test in this experiment have been standardized training.At the same time, formulate scientific and unified testing standards, ensure that the measurement personnel involved in the test, the selected test site and the test method are exactly the same before and after the experiment.When allowing students to perform physical fitness training such as speed endurance, reasonable methods should be used to guide students to carry out necessary warm-up activities, prevent possible sports injuries to the greatest extent possible.At the same time, in order to ensure the validity of the whole experimental results, the exercise intensity and exercise time of all students participating in the experiment are strictly controlled. 10During the whole experiment period, the students in group A and group B only carried out physical fitness training such as speed endurance arranged by the badminton curriculum, in other time periods, they no longer participate in any form of training, and the training methods are shown in Table 1.

Ethical Compliance
Research experiments conducted in this article with animals or humans were approved by the Ethical Committee and responsible authorities of Chengdu University following all guidelines, regulations, legal, and ethical standards as required for humans or animals.

Analysis of the basic situation of the two groups of students before the experiment
The basic information on the age and gender of the two groups of students is shown in Table 2.
According to the data in the Table above, there was no significant difference in the basic physical information such as age, height, weight, etc. between the students in group A and group B before the experiment, P<0.05.
