Quantitative Evaluation Method of Physical Fitness Factor Indicators in Youth Endurance Running Events.

Adolescents are in a critical period of physical and intellectual development, and their growth represents the future of a country. However, with the rapid development of social economy and science and technology, sports and health-related education has not been fully developed, and due to some deviations in the current school curriculum, the physical quality of young people generally declines. Endurance running is a comprehensive index to measure a person's physical fitness. It reflects the basic motor function of the matrix. It is a must-test item in the physical fitness test of young people. However, the level of endurance running has shown a downward trend in recent years. In the current endurance running training, there are many disadvantages such as extensive training methods, low efficiency, and human errors during detection. In order to improve the performance of endurance running, this paper establishes the index system of endurance running elements by introducing the concept of healthy physical fitness. Based on the elements of endurance running, the article made a detection system and compared it with the standard test method. The data showed that P < 0.001 , indicating that the test results of the two were consistent. The detection system in this paper is suitable for the detection of physical fitness index elements. Then, the endurance running performance of the selected 124 adolescents was combined with the physical fitness index elements, and the correlation was analyzed, indicating that the endurance running level is closely related to the human body shape, cardiopulmonary function, muscle strength, and endurance level. Systematic testing and quantitative results showed that body mass index was significantly correlated with endurance running performance in adolescents (P < 0.01). Also, the number of vertical jumps in place was significantly correlated with the number of sit-ups completed (r= 0.55, P < 0.01). This strongly suggests that it is important to quantitatively evaluate the fitness factor indicators of endurance running in adolescents. [ABSTRACT FROM AUTHOR]
