To be able to increase kick frequency requires anthropometric factors and adequate physical conditions. Anthropometry that is very important is the length of the leg and a very important physical condition is the strength of the leg muscles. For this reason, the length of leg and strength of leg muscles which is related to the frequency of straight kicks need further investigation. This study aims to determine the relationship between the length of the leg and strength of leg muscle to the frequency of straight kicks. This research is a correlation study with data collection using tests and measurements. The population of this research is 70 male pencak silat at Junior High School of PGRI-1. From this population, 33 peoples were chosen by random sample selection. The test is a measurement of leg length using an antrophometer (cm). Measurement of leg muscle strength with leg dynamometer (kg), and frequency of straight kick measurement using a hand box and stopwatch by measuring the number of kicks in one minute. Data analysis was performed using Pearson correlation and multiples regression.

Physical exercise can increase systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate (FR), and body temperature (BT) exercise. The increase in the body's vital signs can be overcome by consuming electrolyte solutions before exercise. The purpose of this study was to determine the effect of consuming 500 mL of electrolyte solution orally 20 minutes before exercise. The intensity of exercise is 70% of the maximum pulse rate with a duration of 30 minutes, the effect of which is to decrease the SBP, DBP, PR, and exercise BT. This experimental study used a pre and post test control group design, in which 18 subjects were divided into two groups and given different treatments, namely Klp-1 was given mineral water and Klp-2 was given electrolyte solution with the same volume. Differences in treatment results were analyzed using the T-Independent test at the significance of < 0.05. The difference in mean SBP, DBP, PR, and BT between groups after exercise was p = 0.005, p = 0.320, p = 0.000, and p = 0.100. So giving 500 mL of electrolyte solution 20 minutes before physical exercise can reduce SBP and PR (p<0.05) but can't reduce DBP and BT (p>0.05). Therefore, it is recommended to consume 500 mL of electrolyte solution 20 minutes before physical exercise.

Background: The agility is very important for a football player to achieve the desired achievement. It requires training that supports the agility of the biomotoric component. Objective: The purpose of this study was to investigate the effect and differentiation of the training of dribbling spheres to form stars with different doses of agility. Method: This study used pre-post group design, where the subjects of junior high school students on Mengwi Badung sub-district were 48 people divided into two groups then given different treatment. Group 1 was given a training on dribbling a star ball with a length of 25 meters as many as 10 reps 2 sets. Group 2 was given training on the same track as many as 5 reps 4 sets. Each group is trained 3 times per week for six weeks. The data obtained were analyzed using t-test formula at 5% significance level. Result: The value of t arithmetic in Groups 1 and Group 2 is greater than t table (respectively 11,679> 2,069 and 8,533> 2,069). The t value of the difference between Group 1 and Group 2 is smaller than t table (1.557 <2.013). Conclusion: It was concluded that there is an effect of the training of dribbling the ball on both groups against agility but no difference in effect Training dribble ball 10 reps 2 sets and 5 reps 4 sets against agility. Suggestion: It is advisable to provide varying training on both types of training to reduce the saturation in exercise.
