Swiss Ball-Based Core Stability Exercise for Students-Athletes of Pencak Silat in Pontianak: Experimental Study

Abstract

The core muscles are essential for stabilization and strength building in all sports activities. This study aims to determine the effectiveness of the Swiss ball-based core stability training model for student-athletes of Pencak silat. Methods: This study used an experimental method with a pretest-posttest control group design. The subject of this research was the student-athlete of Pencak silat in Pontianak. Specifically, the sample was student-athletes aged 15-17 years. The respondents of this study were 60 student-athletes who were divided into two groups, the experimental and control groups, with 30 respondents in each. Analysis: Quantitative data analysis techniques were used to determine the effectiveness of the exercise model with plank instruments and modified bass tests of dynamic balance, before and after treatment. Data were analyzed using SPSS Statistics version 16. Results: The results obtained from the core muscle strength test using the plank instrument before was 1.8630 and after being given treatment was 2.763, concluded that the experimental group's core muscle strength was higher or more effective than the control group. While the value of dynamic balance with the modified bass test instrument obtained before was 26 and after being treated was 35.83. Conclusion: The balance test of the experimental group was higher or more effective than the control group. Based on preliminary and posttest evidence, Swiss ball-based core stability exercises effectively improve core muscle strength and dynamic balance. The effectiveness of the Swiss ball-based core stability exercise must be accompanied by a pattern of exercise that is in accordance with the muscle group and anatomical adaptation of the exercise according to the athlete's ability.
