Study
Purpose: .This study aimed to determine the relationship between aerobic capacity and stroke count as an indicator of stroke efficiency in 50-meter breaststroke swimming among club swimmers.
Materials and methods: .This study employed a quantitative approach with a correlational research
Design: .The participants consisted of 15 club swimmers selected using a purposive sampling technique.Aerobic capacity was assessed using the Beep Test (Multistage Fitness Test) to estimate maximal oxygen uptake (VO₂max).Stroke count data were obtained through a 50-meter breaststroke swimming test by calculating the total number of stroke cycles performed during the swim.Data were analyzed using descriptive statistics, the Shapiro-Wilk normality test, and the Pearson product-moment correlation test with a
Significance: level of 0.05.
Results: .The
results showed that the swimmers had an average VO₂max of 46.18 ml/kg/min and an average stroke count of 29.93 strokes.The normality test indicated that both variables were normally distributed.Pearson correlation analysis revealed a significant negative relationship between aerobic capacity and stroke count (r = -0.854;p < 0.05).These
Findings: indicate that swimmers with higher aerobic capacity tended to perform fewer stroke cycles during the 50-meter breaststroke event.
Conclusions: .Aerobic capacity is significantly associated with stroke efficiency in 50-meter breaststroke swimmers.Higher aerobic capacity may contribute to more efficient movement patterns, allowing swimmers to maintain effective propulsion with fewer stroke cycles.Therefore, aerobic capacity and stroke count can be considered important indicators in swimming performance evaluation and training programs.
