Endurance and Dynamic Balance in Bali Surfers: A Cross-Sectional Study

Introduction: Surfing is an extreme sport that requires balance, strength, and core muscle endurance to maintain body stability while maneuvering on a surfboard. The core muscles are crucial in supporting dynamic balance, making good core endurance essential for surfers to sustain their position and reduce the risk of injury. This study aims to analyze the relationship between core muscle endurance and dynamic balance in surfing athletes in Bali. Methods: This study employed a cross-sectional design with an analytical approach. The sample was selected using a consecutive sampling technique (non-probability sampling), consisting of 60 surfing athletes aged 18–35 with a minimum of one year of experience in Bali. Core muscle endurance was measured using the plank test, while dynamic balance was assessed using the Y Balance Test, which has been validated for reliability. Data were analyzed using the Spearman-Rho test. Results: The Spearman-Rho test showed a p-value of 0.000 (p < 0.05) with a correlation coefficient of -0.594, indicating a negative relationship between core muscle endurance and dynamic balance. Other factors like surfing techniques and muscle load distribution may also influence balance. Conclusion: Higher core muscle endurance does not necessarily correlate positively with dynamic balance. Further studies are needed to explore additional factors influencing dynamic balance in surfing athletes.
