The purpose of this study was to analyze the open spike motion to identify the performance of Semarang Elite Athletes. The open spike technique in volleyball is indispensable as an attacking strategy because it has a high potential to score. The type of research used is analytical research with a research method in the form of One Short Case Design. The population in this study consisted of 11 PORPROV 2022 athletes and was taken using total sampling. This research was carried out at the PBVSI (Indonesian Volleyball Federation) of Semarang City and each sample had signed an informed consent as evidence of approval for the research carried out. The data in this study were obtained from video recording analysis when the sample did an open spike by using Dartfish version 8.0. The results showed that the average time value achieved by volleyball athletes in Semarang was 1.01 seconds and the average impact was 0.57 seconds. This shows that the spike done by the athlete is quite effective. This study has limitations because it only measures kinematic data, so it is hoped that further research can be deepened by measuring kinetic data such as arm strength and leg muscle explosive power on the results of the open spike carried out.

Basketball relies on ideal physical conditions. Power, agility, and strength are three of the most significant physical characteristics. To develop an appropriate training program depends on age, knowledge of power, agility, and strength are required. The study's goal was to examine power, agility and strength as a function of age. Ex post facto sampling was used in this study, and it was done using the purposive sampling strategy. Research participants were basketball junior players aged 15 to 18 years who were divided into 3 groups based on age. Vertical leap, 505, barbell squat, and bench press were the test instruments used. Kruskal Wallis and post hoc tests were used to analyze the research data. The power analysis was found to be 0.041>0.05, agility 0.094>0.05, leg strength 0.0010.05, and arm 0.0000.05 based on the Kruskal Wallis test results. The sig value of the post hoc test on the study of leg and arm strength was 0.0000.05. In conclusion, there was no significant difference between the analyses of power and agility, but there was a significant difference between the analyses of arm and leg strength at the ages of 15 and 18. The results of these findings can be used to increase the knowledge base and as an evaluation material for coaches for their athletes.
