Physical Fitness Index Characteristics And Correlation Analysis For Undergraduates Of Substandard Endurance Running Performances

Health is precious wealth of human society, and is an important guarantee for human,s survival and development. Perfect health is a state of physical, mental, behavior and moral awareness of body and mind,and it is also an adaptation on human daily life, work, study,recreation and leisure, "body and mind". Good physical fitness is one of the most important sign of good health, and it is also the material basis to enjoy good life, improve work efficiency and enhance the ability of dealing with the emergency incidents. "Health Fitness Theory" swept the world of sport, though it was introduced into the domestic just ten years,and the test results have important guiding value the of student fitness activities.The health problems of national youth population especially for college students, has been highly concerned about the state, society, schools and families. In recent years, college students physical test results show that the college students,physical fitness presents a slow downward trend. And among this, the undergraduates of substandard endurance running performances has caused particular concern because of its not up to health standard.In this paper, we take undergraduates of substandard endurance running performances as samples, and we will mainly analyze their health fitness characteristic and the connected indicators. By using descriptive analysis and Pearson correlation analysis to analyze the physical fitness indicators, we can understand their physical fitness conditions and analyze the effect factors of endurance running and enhance the level of college students,physical fitness whose endurance running are not up to the health standard for your reference.Result showing:(1)The test result of Hebei undergraduates of substandard endurance running performances indicates that the whole endurance running test is under the normal level, but the most of the other indicators are above the normal level, and the state of the body is good which is normal level, and the respiration function is just so. Which boys are better than girls, and to the explosive force and muscular endurance are also boys better than girls. But girls are better than boys on the body flexility. The score of the undergraduates of substandard endurance running performances is interrelated to their body quality.(2)Physical fitness index characteristic of undergraduates of substandard endurance running performance.Health-related physical fitness: cardio-pulmonary function is poor, which on the respiration function, boys are better than girls. To the body composition BMI, and the percentage of body fat in the normal state, girls are better than boys. So the whole body composition is that girls are better than boys; muscular fitness endurance running in non-compliance generally indicate bad state of muscle strength, and the girls, muscle strength are weaker than boys, but to the muscle fitness endurance, girls are better than boys. And the girls, fitness flexibility are also better than the boys,. Fitness aspect of the moving body, the moving function of the physical fitness of undergraduates of substandard endurance running(which includes balance, out break and response) is just so, and the girls are slightly better than boys.(3) Cardio-pulmonary fitness index characteristics and other physical fitness index correlation analysis for undergraduates of substandard endurance running performances. Related boys particular case,grip strength, BMI and seating reach, these three indicators are highly correlated and significant. Specifically related to girls, the waist-hip ratio, waist circumference and body fat percentage, these three indicators are highly relevant and significant. This result shows that the score of physical fitness of undergraduates of substandard endurance running performance is closely related to their body composition, and they are conference, but different sexes have different character, and the boys, muscle strength is relevant obvious.Conclusion: 1. Endurance Race is not up to physical fitness characteristics of college students, although the individual indicators cardiorespiratory fitness level is poor, but it is not an indicator of poor physical fitness, everything indicators are poor.2.Low levels of cardiorespiratory endurance students and relevance of each index by gender, vary.Recommendation: 1.To focus on cardiorespiratory fitness, targeted practice; to strengthen the self-weight boys and effective management, not excessive pursuit of slim girls,may be appropriate to add some strength training aspects.2.Transform endurance run training methods to improve muscle strength and flexibility quality boys practice through a variety of physical activity, so as to achieve high efficiency performance.Girls attention body composition, waist focus to the site and fat content of the body, the body can start to grab.
