Middle School Students With Elastic Mechanics And Fitness Results Of Abs Experimental Study

This research now according to young students strength, stamina diathesis decline, based on the status of the physical growth characteristics and middle school school physical education's actual situation, creating the student movement load and interest for the elastic belt setting-up exercise development characteristics of power quality. This paper used the literature material method, experimental method, mathematical statistics method, the selection of xi'an two middle school aged 13 to 15 years old students as the object, by ten weeks the elastic belt setting-up exercise fitness movement experiment, obtains the following main results.Results:1. Elastic belt with music beats for abs is from the upper body exercises to lower limbs. According to the principle, points with increasing first and second primary training 5 weeks training stages, level 1 phase for 2-4kg selecting resistance, secondary stage with selected bounce for 4-6 kg, two phase load strength, all choose the heart rate, in 100-150 times/points between, self feeling inventory in 12-15 between, each exercise 30 minutes above, every week 3, basic satisfy students strength, endurance fitness requirements.2. Ten weeks elastic belt setting-up exercise after exercise reflects the student morphological index, height and weight, but no significant effect can make hiplines difference value is improving and have significant differences.3. Ten weeks elastic belt setting-up exercise after exercise that the students steps index, vital capacity, the control group was significantly higher each index does not change significantly.4. Ten weeks elastic belt setting-up exercise after exercise, reflects the student strength quality indexes proves, grip, push-ups cast (male), oblique body pull-ups (female), sit-ups, standing long jump are improved, there is significant difference; The endurance, sensitive reflects the student has also improved quality indicators and significant difference; But no significant flexibility making impact.5. Through the screening test index of more than 10%, selected as elastic belt fitness index in the process of performance evaluation indicator.Conclusion:1. Elastic belt setting-up exercise in the content, load exercise intensity and frequency strength, sport reached the students' fitness requirements. And with music rhythm motivating students' interests. Is a set of can improve students' strength, endurance quality has the actual operational setting-up exercise.2. Elastic belt setting-up exercise after exercise can make the morphological index reflects the student improve difference value is the upper arm surrounds. Reflect function index steps index increased, the lungs stronger, explain elastic belt setting-up exercise on human cardiovascular function, respiratory function also have well effect.3. Elastic belt setting-up exercise can significantly improve students after the power quality, but also to student's endurance, sensitive quality improved.4. Through the elastic belt setting-up exercise fitness results index analysis of the vital, found about grip, throwing across, proves, push-ups (male), oblique body pull-ups (female), standing long jump, sit-ups index before and after the experiment has improved significantly, therefore, can choose for evaluation index of teenagers force fitness effect.
