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.

Basketball is a very technical sport that requires good physical condition. A talent skills assessment instrument specifically created for high school basketball players is critical to advancing their growth in Indonesia. The aim of this research is to design, create, and evaluate the validity of a skills evaluation instrument specifically created for junior high school basketball players in Indonesia. For this development research design, junior high school basketball players who had completed the training programme were selected as samples. Coefficient alpha analysis was used to assess the validity of the instrument, and the results were very encouraging. The alpha coefficient of all items is close to or equal to 1.00, which indicates the validity of the proposed evaluation instrument is very good. With the help of this evaluation instrument, athletes can be grouped based on their skill level and carry out talent evaluations more successfully. This makes it easier for coaches and team leaders to create training plans that are more focused on the skill areas that each athlete needs to improve. As a result, this assessment instrument is useful for individual and collective team growth. The findings of this research demonstrate the reliability of the development instrument created and its potential to improve the training and growth of junior high school basketball players in Indonesia. By utilising these assessment techniques, we can ensure that coaching efforts concentrate on the unique needs of each athlete, resulting in better results in the game of high school basketball. However, these findings also point to a number of topics that require further investigation. Future research could look at larger samples and include additional elements such as athletes' physical, mental, and social conditions for a more thorough examination. In this way, we can understand more deeply the elements that influence the abilities of junior high school basketball players. The skills evaluation instrument created specifically for junior high school basketball players in Indonesia has good validity. This can be a useful tool to increase athlete growth and develop basketball in Indonesia. [ABSTRACT FROM AUTHOR]
