| The difficult movements of the four groups in competitive aerobics are quite different.Among them,the difficult movements of Jumps & Leaps are a group of difficult movements that show the athletes’ special abilities such as explosive power,the ability of turning in the air,and the ability of landing and buffering,also is the athletics aerobics athlete selects the frequency highest one group of difficulty movement.The quality of difficult movements of Jumps & Leaps has direct influence on the score of completion and difficulty,and is an important factor to decide the result of sports.Many studies have shown that the combination of plyometrics and special training can be well combined with specific movements and has a significant effect on improving athletes’ explosive power.Therefore,based on the analysis of the technical and anatomical characteristics of the Jumps & Leaps difficult movements of competitive aerobics,this paper makes a suitable training plan of rapid expansion and contraction,this paper analyzes the effect of plyometrics on the quality of jump and jump performance of competitive aerobics athletes.Through documentary,expert interview method,experimental method and other research methods,rapid competitive aerobics athlete’s telescopic compound training as the research object,put forward the promotion of competitive aerobics athlete jump and jump a difficulty to complete the quality of the rapid expansion of plyometrics scheme,and analyses the influence of the grade of the athlete.Selection of Guangzhoubaiyun college competitive aerobics athlete 36 people as experimental object,based on the study the effects of plyometrics can competitive aerobics athletes Jumps & Leaps difficulty of the master,and different parts of the rapid expansion composite training whether impact on Jumps & Leaps difficulty movement to complete the quality difference,the subjects were divided into three groups,the traditional strength training group(Group A),lower limb plyometrics + upper torso traditional strength training group(Group B),plyometrics group(Group C),the training time of 12 weeks.After the experiment,mathematical statistics is used to analyze the difficult movements and related qualities of the athletes’ Jumps & Leaps.The main conclusions of this paper are as follows:1.plyometrics and traditional strength training can both improve the lower limb explosive force and anaerobic strength endurance of competitive aerobics athletes.However,the training effect of the three groups was different after the experiment.The results showed that: the plyometrics group had the highest improvement;The lower limb were treated with plyometrics,and the upper limbs and trunk were treated with traditional strength training;The traditional strength training group showed the least improvement.2.After 12 weeks of training,the plyometrics can effectively improve the explosive power of the upper body of competitive aerobics athletes,while the traditional strength training has no obvious effect on the improvement of the explosive power of the upper body of competitive aerobics athletes.3.Both plyometrics and traditional strength training can improve the completion quality of difficult movements such as jump and jump.After the experiment,the quality of the three groups of athletes was improved,but the traditional strength training had no obvious effect on improving the accuracy and landing stability of the720° straight jump.The results show that plyometrics has the best effect on the quality improvement of jumping and jumping movements,and plyometrics has more advantages than traditional strength training.4.The landing stability of the "cossack jump 1/2 twist to push up" movement of the athletes was enhanced after the rapid expansion and contraction of the upper body and trunk training,which indicated that the plyometrics of the upper body and trunk training played a promoting role in improving the completion quality of the complex difficulty movements in the Jumps & Leaps difficult movements. |
