Abstract

The aim of this research is to investigate the effects of the distance per stroke on race performance and speed in 11-12-year-old swimmers, and to identify and enhance the athletes' performance. A total of 179 male swimmers aged 11-12, who have been licensed and actively participating for at least 3 years, were included in our study. The competitions were recorded with permission from the Turkish Swimming Federation. By analyzing the footage, the distance covered after the start, stroke counts, stroke frequencies, and race times were observed, and the distances covered per stroke were calculated. The obtained data were evaluated using IBM SPSS Statistics 24 software with Pearson and Spearman tests at a confidence interval of p<0.05. A moderate negative correlation was found between the distance covered per stroke and the performance (r=-0.587). Upon examining the results, it was found that the average distance covered per stroke of those ranked in the top twenty-four was greater than that of slower performers. The change in the distance covered per stroke during the first and second 25 meters of the 50-meter freestyle race was statistically significant (p<0.05). In conclusion, it was observed that the distance covered per stroke significantly affects the speed in 50-meter freestyle races, indicating its importance for observing a swimmer's performance and technical capacity. The results of this research offer a different perspective in the design of swimming training and education programs. Coaches and educators can develop more effective strategies to enhance the performance of young swimmers and improve training applications based on these findings.
