Sepak Takraw Analysis

CHAPTER 1

PROJECT BACKGROUND

1.1 Background of Study

Generally, Biomechanics can be described as the implementation of mechanical laws to living things or structure, specifically to the human body locomotor system (Garner, 2003). “Sepak takraw” is a kind of court game of tossing a rattan ball over a net barrier which played by two opposing teams consisting of three players for each team. They can use any part of the body exclude their hands. One of the position that plays crucial role in this sports is called “tekong”. “Tekong’s” function in this sports is to serve the “Sepak takraw” ball towards the opponent across the net barrier by using their legs. Therefore, the purpose of this project is to conduct the biomechanics analysis

The serve is the first attacking strike in the modern game of Sepak Takraw. Notational analysis conducted by National Sports Institute of Malaysia has shown that a good serve contributes to scoring points and winning the game (Hamdan, Suwarganda, & Wilson, 2012). High speed and accurate placement of the ball is the two main element that can contribute to the performance of the Sepak Takraw “tekong”. Via conducting the biomechanics analysis using Kinect software, the body joint motion of the “tekong” while perform the serve can be analyzed. The movement of “tekong” to serve the ball will affecting the speed and placement of the ball to the opponent sides. The motion analysis by using depth camera motion capture system conducted will analyze what is the best technique for a “tekong” to serve the ball in order to locate the ball to the desired point as well as increase the speed of the ball when serving the “Sepak takraw” ball. The strength and weaknesses of the “tekong” will be analyzed and the best serve pattern will be suggested in order to improve their

To analyze the body joint motion of sepak takraw “tekong” during serving the ball by using kinect software. ii. To provide descriptive kinematic factors that correlate with the ball speed and placement during serving the sepaktakraw ball. iii. To enhance and and implement the best serve technique for “tekong”. iv. To provide suggestion on the best movement that the tekong should implement to become a good and consistent Sepak takraw server.

1.4 Scope of Study

The study involved the analysis using motion capture using kinect software on the UTHM Sepak Takraw “tekong”. Motion of one sample of tekong will be captured in the training sessions. Predetermined number of serves attempt will be perform and recorded. The data on motion on tekong body joint of tekong will be retrieved by using kinect software and analyzed. The analysis on joint motion will be done in three major axis which is x,y and z. The relation between the displacement of 17 point of human body joint to the speed and placement of the ball which contribute to the “tekong” performance also to be analyzed (Zawi & Yusoff, 2008). The data will be analyzed using selected kinematic variables that is displacement and velocity of the joint movement. The data exist should be able to describe the performance of the “tekong”. The data also should help in order to provide the suggestion for the best movement pattern to be implement by the
