Athletics is a common sport that includes running, jumping, throwing, and walking races. In the training, competition, and teaching of track and field sports, various models are often used to help understand and improve the performance of athletes. To ensure the accuracy of these models, it is necessary to conduct reasonable validation. This article will analyze the validation criteria for the rationality of models based on track and field sports. In track and field sports, common models include biomechanical, physiological, and kinematic models. Biomechanical models can help us understand the movements and power distribution of athletes; Physiological models can predict the fatigue level of athletes under different conditions. Kinematic models can analyze athletes’ exercise patterns and optimize their techniques. Read More Read Less

Abstract In recent years, with the continuous changes in social environment and educational models, college students are facing increasing pressure and mental health problems are gradually becoming prominent.

In recent years, with the continuous changes in social environment and educational models, college students are facing increasing pressure and mental health problems are gradually becoming prominent. To effectively address these issues, research on the mental health of college students based on multiple stress management intervention plans has become a topic of great concern. This article will introduce and evaluate the study. This study explores the effectiveness of numerous stress management intervention programs on the mental health of college students. By comparing the experimental group and the control group, the study found that numerous stress management interventions can improve the mental health level of college students, reduce negative emotions such as anxiety and depression, and improve self-efficacy. Specific intervention measures include cognitive reconstruction, emotional regulation, coping skills training, life planning, and other aspects. The research results are of great significance for improving the mental health level of college students and promoting their comprehensive development. Read More Read Less

Abstract The penalty angle test in basketball games based on action view technology is a method that uses a video analysis system to conduct detailed research on penalty situations in basketball games. Through action view technology, various details of the free throw process can be collected and analyzed, providing valuable training data for basketball players and coaches. This testing method mainly... The penalty angle test in basketball games based on action view technology is a method that uses a video analysis system to conduct detailed research on penalty situations in basketball games. Through action view technology, various details of the free throw process can be collected and analyzed, providing valuable training data for basketball players and coaches. This testing method mainly utilizes high- resolution cameras to capture the free throw process from multiple angles and combines action view technology to analyze the video frame by frame. By accurately measuring and evaluating each action and detail during the free throw process, a series of important data can be obtained, including player posture, coordination of actions, power transmission, and ball trajectory Read More Read Less
