The purpose of study was to find out the effects of low Intensity plyometric training combined with aerobic training on explosive power of school kabaddi players. To achieve the purpose of the study, thirty school kabaddi players in, Alagappa Fitness foundation, Karaikudi, Tamilnadu were selected as subject at random and their age group range between 13 to 15 years. The study was formulated as pre and posttest random group design, in which thirty subject were divided into three equal groups. The experimental group-1(n=10, LI-PT) underwent low intensity plyometric Training. The experimental group-2 (n=10, LI- PT-AT) underwent low intensity plyometric training combined with aerobic training and group 3 served as control group (n=10, CG) did not undergo any specific training. In this study, two training programme were adopted as independent variable, i.e., low intensity plyometric training, and low intensity plyometric training combined with aerobic training. The explosive power was selected as dependent variables, it was tested by vertical jump test. The selected two treatment groups were performed three days in a week for the period of eight weeks, as per the stipulated training program. The selected performance parameters were collected before and after the training period. The collected pre and post data was critically analyzed with apt statistical tool of analysis of co-variance, for observed the significant adjusted post-test mean difference of three groups with respect to each parameter. The scheffe’s post hoc test was used to find out pair-wise comparisons between groups with respect to each parameter. To test the hypothesis 0.05 level of significant was fixed in this study. The results proved that the selected both training produce significant improvement on explosive power rather than the control group. However, plyometric training combined with aerobic training have produced greater improvement on explosive power than the plyometric training alone.

Developing countries experienced insufficient levels of physical activity, particularly Saudi Arabia. In recent decades, Saudi Arabia has been experiencing a significant change in economy, urbanization, modernization, extensive and rapid demographic changes, and lifestyle transformation. These changes had negatively increased sedentary behaviors, inactivity physical activity, and lifestyle. Physical inactivity increases the risk of non-communicable and disease chronic diseases. Objectives: To highlight the gap in information such as gender inequality, cultural sensitivity, and social norms, including geography. Methods: Saudi Digital library, Google scholar, and UOW library. The terms used are “physical activity”, and “exercise” and research strategy were also adopted. Results: The recent Household Sports Practice Survey Bulletin in 2019 showed significant inequality between males and females. Also, the data showed different results relative to school type and gender. There are specific socio-cultural factors that limit women to participate in physical activities. Females have a low rate of total labor participants in the country. Geographical factors should be considered when establishing a promotion plan for physical activity, and there are no studies that focus on the effect of climate on participation in physical activity. Conclusion: The Saudi country has commenced numerous initiatives to improve people's health and well-being, and hopes to achieve this by 2030. It is important to build a community health center for females because there is a segregation policy to separate males from females in public places and workplaces. Having a national policy or promotion plan and collaborating with government parties is important. In addition, monitoring and evaluating the programs is important to ensure their success.

As a leading force in new forms of exercise and fitness, sports apps have successfully attracted the attention of young college students by integrating the exercise mode of "Internet and Sports". In the process of extracurricular physical exercise for college students, the accompanying activities of sports apps have brought diverse impacts. It enriches the forms and projects of extracurricular physical exercise for college students, makes exercise motivation more diversified, and effectively enhances the enthusiasm of college students to participate in extracurricular physical exercise. This article uses literature review, questionnaire survey, and mathematical statistics to study the impact of using sports apps on physical exercise among sports students at Zhejiang Normal University.

To advance the development of Chinese women's pole vaulting technique, three-dimensional photogrammetry and video analysis methods were utilized to conduct kinematic analysis on the technique employed by Ren Mengqian, an outstanding female pole vaulter in China, during the 2019 National Indoor Track and Field Championships finals from an energy transfer perspective. The findings indicate that during the energy acquisition stage, Ren Mengqian executed a reasonable jumping action with appropriate jumping angle and timing that met technical requirements. However, during the energy storage stage, her bow rod had suboptimal effects in her fourth trial jump while insufficient bending of the rod occurred in her fifth trial jump which affected pole energy storage. In terms of energy release stage, Ren Mengqian maximized elastic potential energy through stretching but required acceleration for maximum vertical speed.
