Abstract

This study aims to determine the results of shooting free throws which were analyze biomecally using kinovea software and to find out details of the angle (degrees) resulting from shooting free throw. Design of this research is descriptive quantitative with persentage by analizyng the free throw shooting motion which is 4 categorized; result of point shooting by applying the BEEF principle, shooting result point not applying the BEEF principle, shooting result no point but applying the BEEF principle, shooting result no point and no applying BEEF principle. The population are who were members of the UKM basketball Jenderal Soedirman University. The sample in this reseacrh amounted to 30 people. The analysis shooting motion the incoming ball free throw by applying the BEEF principle gets the highest percentage results, 46.6%; Balance of 83.90°, Elbow 89.21°, all off sample of this category is focused on the target shooting, follow through 179.98°. Shooting free throw by applying the correct BEEF principle will get a greater percentage of balls in than not applying. Of course with the support other dominant factors such as mental, self efficacy and antropometry.

Abstract

The training method is one way to improve the physical condition of athletes. One of the training methods that can be used to improve the components of physical condition, especially the strength of the abdominal muscles, is the practice of hitting tires using a hammer. The purpose of this study was to determine the effect of hitting tires using a hammer on the strength of the abdominal muscles of judo athletes in Brebes Regency. This research is experimental research with one group pretest posttest design. The number of samples in this study were 15 judo athletes (5 male and 10 female) using total sampling. The instrument used in this study was a sit up test with a test validity of 0.96 and a test reliability of 0.94. Data analysis used the prerequisite test for normality and homogeneity, while the hypothesis test used the Paired Sample t-Test by comparing the pretest and posttest scores in one group. The results showed that there was a significant effect of hitting tires using a hammer on the strength of the abdominal muscles of judo athletes in Brebes Regency with a significance value of 0.000. Conclusion: The practice of hitting tires using a hammer provides an increase in the strength of the abdominal muscles of judo athletes in Brebes Regency. The increase in abdominal muscle strength by 45.98%, so that the exercise of hitting the tires can be applied in an exercise program to increase the strength of the abdominal muscles of judo athletes
