Abstract

Lempar cakram merupakan salah satu nomor lapangan dalam cabang olahraga atletik. Nomor lempar cakram termasuk nomor yang sulit dan sampai saat ini perkembangannya di Indonesia sulit mengalami peningkatan dalam waktu yang singkat. Penelitian ini bertujuan untuk dapat mengetahui kontribusi paling besar antara kekuatan otot lengan, kekuatan otot perut, daya ledak otot tungkai dan tinggi badan pada prestasi lempar cakram. Penelitian ini dimulai pada tanggal 27 Desember 2020 di Lapangan Velodrome rawamangun dan sekret KOP atletik UNJ. Sampel penelitian ini sebanyak 6 orang dengan jumlah populasi sebanyak 20 orang sebagai atlet lempar DKI Jakarta dengan metode penelitian menggunakan statistik deskriptif kuantitatif. Sedangkan pengambilan data dilakukan dengan melakukan tes Push up, sit up, vertical jump, pengukuran tinggi badan, serta lempar cakram. Hasil penelitian terhadap kontribusi kekuatan otot lengan terhadap prestasi lempar cakram sebesar 20,9%, kontribusi kekuatan otot perut terhadap prestasi lempar cakram sebesar 1,7%, kontribusi daya ledak otot tungkai terhadap prestasi lempar cakram sebesar 19,8%, kontribusi tinggi badan terhadap prestasi lempar cakram sebesar 24,1%. Kesimpulan penelitian adalah kekuatan otot lengan, kekuatan otot perut, daya ledak otot tungkai, memberikan kontribusi yang tidak signifikan terhadap prestasi lempar cakram, variabel tinggi badan memberikan kontribusi yang paling besar terhadap prestasi lempar cakram, dan selanjutnya diikuti kekuatan otot lengan, daya ledak otot tungkai, dan kekuatan otot perut. Discus throwing is one of the number fields in athletics. The number of throwing discs is a difficult number and until now its development in Indonesia is difficult to increase in a short time. This study aims to determine the greatest contribution between arm muscle strength, abdominal muscle strength, leg muscle level strength and height in discus throwing performance. This research began on December 27th, 2020 at the Velodrome Rawamangun Field and the Secretariat of UNJ's athletic KOP. The sample of this research was 6 people with a total population of 20 people of throwing athletes in DKI Jakarta. The research method applied a quantitative descriptive statistics method. While data collection is done by doing push up tests, sit ups, vertical jumps, height measurements, and throwing discs. The results of the study on the contribution of arm muscle strength to the discs throwing achievement were 20.9%, the contribution of abdominal muscle strength to the discus throwing performance was 1.7%, the contribution of leg muscle explosive power to the disc throwing achievement was 19.8%, the contribution of height to discusable performance of 24.1%. The conclusion of this research is arm muscle strength, abdominal muscle strength, leg muscle level strength, do not give a significant contribution to the discs throwing performance, height variable gives the greatest contribution to the discus throwing achievement, followed by arm muscle strength, leg muscle level strength , and abdominal muscle strength.
