HUBUNGAN DAYA LEDAK OTOT TUNGKAI DAN KOORDINASI MATA TANGAN DENGAN KEMAMPUAN SMASH DI KLUB BOLAVOLI NUSANTARA DI KURAI KECAMATAN SULIKI KABUPATEN LIMA PULUH KOTA

Abstract

The problem in this study is the inaccuracy of smash performance among volleyball athletes at Club Nusantara in Kurai, Suliki District, Lima Puluh Kota Regency. The inaccuracy of smash execution is influenced by several factors, including leg muscle explosive power and eye-hand coordination. The purpose of this study is to determine the relationship between leg muscle explosive power and eye-hand coordination on smash ability. This study employed a correlational research design. The population consisted of 25 athletes from Club Bolavoli Nusantara in Kurai, Suliki District, Lima Puluh Kota Regency. The sampling technique used was purposive sampling, resulting in a sample of 15 athletes. The instruments used in this study included the Vertical Jump Test to measure leg muscle explosive power, the Hand-Eye Coordination Test to measure eye-hand coordination, and a volleyball smash test to assess smash ability. Data were analyzed using correlation coefficient analysis, followed by a significance test of the correlation coefficient. The results of the study are as follows: (1) There is a significant relationship between leg muscle explosive power and smash ability, with a calculated r-value (r-count) of 0.779, exceeding the r-table value of 0.514. (2) There is a significant relationship between eye-hand coordination and smash ability, with an r-count of 0.689, which also exceeds the r-table value of 0.514. (3) There is a significant simultaneous relationship between leg muscle explosive power and eye-hand coordination with smash ability, as indicated by an F-count value of 5.41, which is greater than the F-table value of 3.88.
