Background: Running speed is a key factor in athletic performance, yet a deep understanding of its impact on performance and injury prevention continues to evolve. An important aspect to consider is how speed influences cadence, stride, and power in trained runners. Method: This study employs an observational method by examining three different running speeds and their effects on the changes in cadence, stride, and power in trained runners, consisting of 15 men and 8 women. For statistical analysis, regression analysis is used to determine the extent to which independent variables influence dependent variables. Results: The data indicates a positive correlation between running speed and running parameters. For men, cadence, stride, and power showed significant changes. Specifically, cadence increased by 1.39% from easy run to tempo run, by 1.46% from tempo run to high intensity, and by 2.78% from easy run to high intensity. Stride increased by 20.66% from easy run to tempo run, by 24.88% from tempo run to high intensity, and by 50.17% from easy run to high intensity. Power increased by 21.11% from easy run to tempo run, by 23.77% from tempo run to high intensity, and by 49.00% from easy run to high intensity. For women, cadence increased by 1.01% from easy run to tempo run, by 1.42% from tempo run to high intensity, and by 2.33% from easy run to high intensity. Stride increased by 13.89% from easy run to tempo run, by 22.42% from tempo run to high intensity, and by 34.22% from easy run to high intensity. Power increased by 19.74% from easy run to tempo run, by 27.12% from tempo run to high intensity, and by 42.59% from easy run to high intensity. Conclusion: The analysis confirms a positife correlation between speed and the observed running parameters, specifically stride and power. Increased speed significantly contributes to the enhancement of cadence, stride and power in trained runners. However, changes in cadence do not always align with increased speed, with greater changes observed in stride and power compared to cadence.
