Given the distance, energy consumption and football referees' physical challenge during matches, it is crucial that their speed, endurance, and strength should be enhanced. It is in this perspective that this One-Group Pretest-Posttest Design quasiexperimental research, aims to (a) validate a mixed-training program to enhance Primus League football referees' speed, endurance, and strength. The research also aims to (b) gather evidence on the program reliability and effectiveness. The sample consisted of 15 Primus League football referees (n=15) who attended a five-week training program with sessions held 3 times per week. During an expert panel, eight Fitness and Vitality Enhancement (FVE) professionals validated the program and later the replicability estimation indicated the training program related tests' high reliability (ICC=0.77). The normality assumption was verified, and the results obtained through paired-sample t test, with related sig.<0.025, indicated that the intervention program effectiveness, except the speed component for which there was not enough evidence of the referees' improvement. With bigger sample sizes, it is recommended that the relation between the referees' age, body mass, and speed be established to shed light on the reason of speed component statistical insignificance.

The purpose of this work is to identify the contribution of Esports in promoting Physical Activity and Leisure. This is an exploratory and descriptive research conducted through The bibliographic analysis using The set of databases. The study was based on 551 articles, of which 14 were selected for the development of this work, with 6 of them being analyzed in detail. As a conclusion, it was observed that Esports play a significant role in promoting physical activity and leisure, providing numerous benefits for the health, well-being, and performance of its practitioners. From this research, we can find out the influence of esports on the promotion of physical activity, namely leisure, such as the following some positive impacts and negative impacts on the lives of practitioners. In the context of promoting physical activity and leisure, there are four areas where Esports can play a relevant role: new technologies, active electronic games, media, and the potential for physical activity to improve performance. Considering the indicators, it is essential to adopt strategies aligned with the activity physical, optimizing to the benefits in each one from them. [ABSTRACT FROM AUTHOR]

The implementation of physical fitness tests requires adequate facilities, so technology is needed to make it easier without having to provide facilities. The purpose of this study is to make it easier to get the results of a person's physical fitness level using age, gender, height and weight data through an intelligent system using the naïve Bayes algorithm without having to do a physical fitness test. This research is included in the Experimental research. The method used in this study used machine learning and classification with the naïve Bayes algorithm. Data analysis techniques use probability by using data tests and evaluations. The evaluation used uses accuracy. The population in this study was 100 college students. Training model scheme 98 and test 2 get an accuracy value when training is 100%, on testing an accuracy value of 50%. The best model is used as a reference in predicting new data, using 5 new data where 3 data already know the VO2Max value with the same prediction value and actual value, then 2 new data are not yet known VO2Max value, the 4th data gets a value of 44.2 and the 5th data gets a value of 33.2. The results of VO2Max testing using the naïve Bayes algorithm are declared accountable. Contribution to future research is to multiply research datasets to improve accuracy and improve user interface quality through development research. [ABSTRACT FROM AUTHOR]
