Analysis of Leg Muscle Power and Leg Angle in Jerk Split Movement of SMAKOR Aceh Weightlifters

Weightlifting is a sport that relies on power to lift weights made of iron and covered by rubber; there are two kinds of force techniques in weightlifting, namely the Snatch and Clean and Jerk force types. The objectives of this study are: 1) to analyse the limb muscle power of Aceh SMAKOR weightlifters, 2) to analyse the front limb split jerk angle in Aceh SMAKOR weightlifters, and (3) to analyse the rear limb split jerk angle in Aceh SMAKOR weightlifters. This research uses a quantitative approach with descriptive methods. The sampling technique used total sampling, which amounted to 8 Aceh SMAKOR weightlifters. The collection technique uses test items as follows: 1) The results of leg muscle power in male athletes fall into the deficient category totalling two people (66.66%), and the good category totalling one person (33.33%), with an average value of 51.33, and for the results in female athletes are also in the deficient category totalling three people (60%), and two people are in the good category with an average value of 38.8; 2) From the split limb jerk angle results of male athletes of SMAKOR Aceh, three people (100%) obtained the optimum angle value per the standards set. The results of the front limb split jerk angle test of female SMAKOR Aceh athletes totalling five people (100%) also obtained the optimum angle value per the standards set; 3) The results of the front limb split jerk angle are as follows: the optimum angle value of the front limbs in male athletes has met the standard value set by PB PABSI with a value range of 90-110 and an average value of 104.12 Furthermore, of the five female athletes, 3 of them are in the predetermined value range, the remaining two people exceed the predetermined range with an average value of 111.23; 4) The results of the rear limb split jerk angle, as follows: the optimum angle value of the hind limbs in male athletes has met the standard value set by PB PABSI with a value range of 140-160 and an average value of 151.64, then in female athletes also obtained an angle value that has met the standard value that has been determined with an average value of 158.17.
