KONTRIBUSI KONSENTRASI DAN KELENTUKAN PERGELANGAN TANGAN TERHADAP KETEPATAN SHOOTING FREE THROW BOLABASKET
CONTRIBUTION OF CONCENTRATION AND THE RELATIONSHIP OF THE HANDS TENDER AGAINST THE ACCURACY OF SHOOTING FREE THROW BOLABASKETS
Latar belakang Dalam permainan bola basket, konsentrasi dan kelentukan pergelangan tangan sangat dibutuhkan dalam melakukan shooting free throw. Hal ini dikarenakan kurangnya konsentrasi dan kelentukan pergelangan tangan sehingga kurang maksimal pada saat shooting free throw. Tujuan untuk mengetahui besarnya kontribusi konsentrasi dan kelentukan pergelangan tangan terhadap ketepatan shooting free throw bolabasket. Metode dalam penelitian ini yaitu deskriptif kuantitatif, populasi adalah tim bolabasket putri SMA Negeri 3 Sidoarjo yang berjumlah 12 orang dengan kategori usia 16 sampai 20 tahun, menggunakan instrument penelitian berupa angket dan pengetesan. Hasil Berdasarkan dari analisa data penelitian ini yang dihitung menggunakan SPSS 25 yaitu hasil kontribusi konsentrasi rhitung lebih kecil dari rtabel dan koefisien korelasinya sebesar 0,129 , kontribusi kelentukan pergelangan tangan rhitung lebih besar dari r dan koefisien korelasinya sebesar 0,824 , dan hasil kontribusi konsentrasi dan kelentukan pergelangan tangan koefisien korelasinya sebesar 0.832 , yang artinya model regresi antara konsentrasi dan kelentukan pergelangan tangan bernilai signifikan. Besarnya kontribusi konsentrasi adalah 1,67 , sedangkan besarnya kelentukan pergelangan tangan adalah 67,8, dan secara bersama-sama besarnya korelasi berganda adalah 69,2 terhadap ketepatan shooting free throw bolabasket. Kesimpulan Terdapat kontribusi yang signifikan antara konsentrasi dan kelentukan pergelangan tangan terhadap ketepatan shooting free throw bolabasket putri SMA Negeri 3 Sidoarjo.Kata kunci: Konsentrasi, Free Throw, Bolabasket
ABSTRACT
Purpose In basketball, concentration and flexibility of the wrist are needed in free throw shooting. This is due to lack of concentration and flexibility of the wrist so that it is less than optimal when shooting free throw. The objective is to determine the contribution of concentration and flexibility of the wrist to the accuracy of shooting free throw basketball. Method in this research that is descriptive quantitative, the population is a womens basketball team in SMA Negeri 3 Sidoarjo, amounting to 12 people with an age category of 16 on 20 years, using research instruments in the form of questionnaires and testing. Results Based on the analysis of the data in this study, the results of the analysis of the contribution of the calculated rcount are smaller than rtable and the correlation coefficient of 0.129, the analysis of the contribution of wrist flexion is greater than rtable and the correlation coefficient of 0.824 , and the results of the contribution analysis concentration and flexibility of the wrist the correlation coefficient is 0.832 , which means the regression model between wrist concentration and flexibility is significant. The magnitude of the contribution of concentration was 1.67, while the magnitude of wrist flexion was 67.8 , and together the magnitude of multiple correlation was 69.2 of the accuracy of shooting free throw basketball. Conclusion Based on the results of the calculations, it was concluded that there was a significant contribution between concentration and flexibility of the wrist to the accuracy of shooting free throw womens basketball team SMA Negeri 3 Sidoarjo.Keywords Concentration, Free throw Basketball
