This research was motivated by several problems that researchers encountered in the field, namely: (1) Weak physical condition of students, especially the explosive power of leg muscles, (2) Running ability is not yet optimal, (3) Lack of physical condition building exercises for students, (4) Lack of facilities. and training infrastructure. The aim of this research is to determine the relationship between leg muscle explosive power and 50 meter sprint running speed in PJKR students at Rokania University. This research is a type of correlational research with a sample size of 8 people and analyzed using product moment correlation. The results of the research show that: There is a significant relationship between leg muscle explosive power and the 50 meter run in PJKR students at Rokania University. The results of Product Moment Correlation analysis show Rcount (0.410) > Rtabel (0.400), while Tcount (1.796) > Ttable (1.746). Thus, it can be concluded that the working hypothesis proposed by Ho is rejected and Ha is accepted, which means that hypothesis one is accepted, namely that there is a significant relationship between leg muscle explosive power and the 50 meter run in PJKR students at Rokania University.

This type of research is experimental research, quasi-experimental design, with one group pretest-postrest design. The population in this study was all students in Class XI IPA 1 and XI IPS 1, namely 49 people. The sampling technique is to use a saturated sample or sensu. Based on the Paired Sample T-Test, it can be seen from the t count (14.827) > t table (2.01063) and the sig. 0.000 < 0.05. Thus, it can be concluded that there is an influence of target shooting games on the passing ability of volleyball in Class XI students of SMA Negeri 2 Kampar. The effect of target shooting games on students' passing ability is 93.3%.

This research is of a correlational nature and was conducted among the population of basketball athletes from SMA Negeri 2 Tebo, totaling 20 individuals. A total sampling method was used due to the relatively small population size of 20 male athletes. The research instruments included a 30-meter sprint speed test, a vertical jump test to measure lower limb muscle explosiveness, and a lay-up skills test. Data analysis was performed using the product-moment correlation analysis technique (simple and multiple correlations) with a significance level of ?=0.05.

The research findings indicate that there is a significant contribution between speed and lay-up skills among the basketball athletes of SMA Negeri 2 Tebo, with a contribution rate of 24.40%. Furthermore, there is a significant contribution between lower limb muscle explosiveness and lay-up skills among the basketball athletes of SMA Negeri 2 Tebo, with a contribution rate of 23.44%. Collectively, speed and lower limb muscle explosiveness also significantly contribute to lay-up skills among the basketball athletes of SMA Negeri 2 Tebo, with a contribution rate of 37.57%.
