Determining Dominant Physical Factors in Sepak Takraw Service Capabilities

Abstract

A service technique is an important element in the game of sepak takraw because it is the initial kick made by servers towards the opponent's field as a sign of starting the game. Good service is difficult for opponents to return the ball so that points can be achieved by the server's team. The purpose of this study was to determine the dominant physical factors determining the ability of sepak takraw service. The method used was a correlational study with multiple linear regression analysis. The sampling technique in this study was purposive sampling involving 100 students. This study was carried out from 7th to 13th October 2015 at the Jayapura Sports Building, University of Cenderawasih. The variables of this research were leg length, body weight, core flexibility, leg power, balance and service capability with the formula Y = a + b1X1 + b2X2 + b3X3 + b4X4 + b5X5. In conclusion, the dominant physical factor in the sepak takraw service capability was the leg muscle power variable (X3), because the leg muscle power had the highest standardized coefficient beta value (0.230) compared to other variables.
