Analysis of Strength, Endurance, Flexibility Towards Speed of 100 Meter Bifins Diving Athletes of Shima Sport Club

Introduction

Analysis of strength, endurance, flexibility towards speed of 100 meter bifins diving athletes of shima sport club. Analyze how leg strength, pulling ability, endurance, and flexibility impact 100-meter bifins diving performance. Discover key factors for athlete training programs.

Abstract

This study aims to analyze the relationship between back strength (Back), leg strength (Leg), body pulling ability (Pull Up), cardiovascular endurance (12-minute Run), and flexibility (Sit & Reach) to Bifins performance in 10 diving athletes. Data were analyzed using the Shapiro-Wilk normality test and Pearson correlation. The results of the normality test showed that all variables were normally distributed (p > 0.05). Correlation analysis revealed a positive and significant relationship between the variables Leg (r = 0.653, p = 0.040), Pull Up (r = 0.905, p < 0.001), 12-minute Run (r = 0.638, p = 0.047), and Sit & Reach (r = 0.873, p = 0.001) with Bifins performance. While back strength ( Back ) did not show a significant correlation with Bifins (r = -0.195, p = 0.588). These results indicate that leg strength, pulling ability, endurance, and flexibility are important factors that affect the performance of diving athletes. This study provides a basis for developing training programs that focus on these aspects to improve the performance of diving athletes.

Review

This study offers a focused analysis into the physiological determinants of 100-meter bifins diving performance among athletes from the Shima Sport Club, addressing a niche yet important area within aquatic sports. The clear objective—to analyze the relationship between various physical attributes and bifins performance—is commendable. The selection of common and well-established fitness tests (back strength, leg strength, pull-ups, 12-minute run, and sit & reach) to assess relevant physical qualities provides a solid methodological foundation for exploring these relationships. The use of standard statistical procedures (Shapiro-Wilk and Pearson correlation) ensures appropriate data analysis given the study design. The findings reveal several significant positive correlations, particularly between leg strength, body pulling ability, cardiovascular endurance, and flexibility with bifins performance, providing valuable insights for coaches and athletes. The strong correlations, especially for pulling ability (r = 0.905) and flexibility (r = 0.873), suggest these are critical areas for training emphasis. Interestingly, back strength did not show a significant correlation, which warrants further investigation into the specific biomechanics of bifins diving. A primary limitation, however, is the very small sample size of N=10. While the reported p-values indicate statistical significance within this group, such a small sample severely restricts the generalizability of these findings to a broader population of bifins divers and reduces the study's statistical power to detect smaller, but potentially meaningful, effects. Despite the sample size limitation, this study provides a foundational basis for understanding key performance indicators in bifins diving. The practical implications for developing targeted training programs, focusing on leg power, upper body pulling strength, cardiovascular endurance, and flexibility, are clear and directly actionable. Future research would benefit immensely from replicating this study with a larger, more diverse sample of athletes to enhance the generalizability and robustness of the findings. Additionally, exploring the specific techniques employed by these athletes could shed light on why back strength did not correlate, perhaps indicating compensatory movements or different muscle engagement patterns than initially hypothesized.
