KONDISI FISIK ATLET LEMPAR CAKRAM (DISCUS THROW) PUSAT LATIHAN NASIOANAL B DI SURABAYA

Discus throwing really requires good physical condition, especially in discus throwing, it requires flexibility and explosive power and other physical components. Not only explosive power, other physical conditions play a very significant role in discus throwing, including strength, speed, endurance, flexibility, coordination and balance. This research is a quantitative research with an ex-post facto descriptive approach. In this study, the focus was on the physical condition of the PLATNAS B Discus Throwing athletic athletes. The subjects of this study were 4 PLATNAS B Discus Throwing athletes consisting of 3 men and 1 woman. Based on the results of the research, it was concluded that the physical component of the speed of the PLATNAS B Discus Throwing athletes obtained "good" results for 3 athletes (80%) and 1 athlete (20%) "enough". So that it can be concluded that the speed is in the "good" category. The explosive power component of the disc-throwing athlete's limbs PLATNAS B obtained "very good" results 2 athletes (50%) "good" 1 athlete (40%), and "enough" 1 athlete (10%). So it can be concluded that the explosive power of the leg muscles is in the "good" category. The component of the arm muscle strength of the PLATNAS B Discus Throwing athletes obtained "good" results for 3 athletes (70%) and "enough" for 1 athlete (30%). So it can be concluded that the arm muscle strength is in the "good" category. The component of abdominal muscle strength for disc throwing athletes PLATNAS B obtained "good" results for 3 athletes (60%) and "enough" for 1 athlete (40%). So it can be concluded that the strength of the abdominal muscles is in the "enough" category. The component of the reaction speed of the PLATNAS B Discus Throwing athletes obtained "good" results for 3 athletes (60%) and "enough" for 1 athlete (40%). So it can be concluded that the reaction speed is in the "enough" category.
