THE RELATIONSHIP OF ARM STRENGTH TOWARDS ROCK CLICKING SPEED CATEGORY SPEED OF FPTI BINJAI ATHLETES IN 2021
This Study to know: 1) The arm strength Speed athlete FPTI Binjai in 2021, 2) The speed of climbing Speed athlete FPTI Binjai in 2021, 3) The relationship between arm strength and climbing speed. The population in this study were all 5 athletes of Speed FPTI Binjai, consisting of 4 men and 1 woman. Determination of the sample in this study using total sampling technique, so that the entire population sampled as many as 5 athlete. The variables in this study are arm strength (X) and climbing speed (Y). Data collection methods used were tests and measurements. The measurement of arm strength with a push and pull dynamometer and a climbing speed test is carried out by the athlete climbing as high as 15 meters. The data obtained were analyzed using simple linear regression techniques. The results showed that (1) The arm strength Speed athlete FPTI Binjai had an average of 18.00 and SD (Standard Deviation) was 5.52, with the highest score of 26 kg (20%), while the lowest score was 11 kg (20%). (2) The speed of climbing Speedathlete FPTI Binjai has an average of 12.48 with SD (Standard Deviation) of 5.57, in the sense that the average speed of the athlete to the top is 12''48, with the fastest time of 8 '. '23 (20%), while the longest time is 22''24 (20%) (3) The relationship between arm strength and rock climbing speed can be described from the regression equation obtained, namely Y = 25.301 + 0.278X. Based on the regression equation obtained, it can be explained that every time there is an increase in arm strength by 1%, it will increase the speed in rock climbing by 0.278 points. The relationship between arm strength and rock climbing speed is in a very strong category because the coefficient of determination is 99.7% while 0.3% is caused by other factors. Based on the F test conducted by comparing Fcount with F table, it is obtained, Fcount = 296.64, while Ftable = 7.71 with a significance level of α = 0.05. By comparing Fcount = 296.64> 7.71, it means that there is, from calculations using SPSS, a significance figure of 0.003 is obtained. So that 0.003 <0.05, then H0 is rejected and H1 is accepted, meaning that there is a relationship between arm strength and rock climbing speed for Speed FPTI Binjai athletes.
