Experimental Study Of Muscl Combined With PNF Strech Exercise Interention Effects On Middle School Students Injury

Our examination of sport as a basic national policy implementation has long been the main sport in the examination for junior high when, on students’ physical condition of a means test. Our examination of sport as a basic national policy implementation has long been the main sport in the examination for junior high when, on students’ physical condition of a means test. Shijiazhuang City, the test sports test project consists of three components, namely the long jump, medicine ball throw, 1000/800 meters. Physical examination scores in exams and share weights have increased every year trend of 10 points from 2004 to the current 30 points, the share is also growing share.Due to increased scores, some schools and parents in order to improve student test scores sports, take a short-term high-intensity training focus, mostly due to middle school students usually less exercise, poor physical fitness, many students in the third day of the test sports training in a variety of sports injuries occur. Many students appear after injury for a long time did not dare to sport or unwilling to exercise, which will inevitably lead to a serious decline in physical performance. And in the event of sports injuries, the school, parents and teachers are not properly handle forcing students to continue the movement, but also so that students gradually increased damage.This article is through third grade students understand Shijiazhuang City suffered damage in the basic situation of the type, location, nature in peacetime training, and visited the hospital in Shijiazhuang City, the provincial Second homes and other orthopedic specialists and other departments, found early three students of sports injuries occur most strain fatigue periostitis and calf muscles. In this study, these two kinds of damage as injury prevention, through access to a large number of professional books, and visited the relevant experts to identify the use of massage and PNF stretching these two methods as the primary means of prevention and intervention. The purpose is to find an effective way to sports injury prevention and intervention through experimental method, third-year students in the appropriate promotion, sports for future candidates can effectively prevent and reduce sports injuries occurred in school training. Improve students’ physical health, promotes normal development and successful implementation of school sports physical exam system.The study took place in Hebei Normal University High School for the experiment, selected four natural classes in the third grade, Hebei Normal University High School, where the two classes as the experimental group, the other two classes for the control group.10 minutes before the end of each experimental group students in physical education each massage, PNF stretching the muscles, the control group is used to relax the original way, the traditional way for students walking, jogging or relaxation exercises and other means.In addition to the end of part two groups different than the experimental group and the control group class activities and essential part of preparing the same.1. Compared to the control group students to experiment with before the experiment, fatigue periostitis, calf muscle strain injury occurs both were significantly improved.2. After the students in the experimental group compared with the previous experimental test, fatigue periostitis, calf muscle strain injury occurs both were significantly reduced.3. Compared with the control group, the experimental group of students fatigue periostitis, both calf muscle strain injury incidence rates decreased significantly.4. The experimental group of students standing long jump, medicine ball throw, 800/1000 m student achievement compared with the control group were significantly differe.5. PNF stretching muscle massage combined third grade physical education as part of the end of the relaxation exercises can be effective prevention and treatment of fatigue periostitis and calf muscle strain.6. As students of the physical differences between individual students combine massage PNF stretching muscles adapt this method, resulting in the effect of the intervention is not particularly desirable.
