Use of modern technologies in the performance analysis of an elite runner

Modern technologies have become an indispensable tool in sports science, enabling a detailed analysis of performance parameters for elite and recreational athletes during selected activities or throughout an entire training cycle. This study focuses on the analysis of data collected using the Garmin application for an elite runner, specifically examining two key indicators: heart rate (HR) and cadence/stride length during a half-marathon. This study aims to analyze these key indicators, compare them with additional metrics, and identify how they influence the performance of the elite runner. Furthermore, it explores how the measured values can be utilized in training and competitive preparation. Based on the analysis, the study proposes general recommendations for applying insights gained from performance monitoring devices and suggestions for implementing these technologies in the training process to optimize both training methods and race strategies. The results highlight the importance of maintaining a stable HR, which the analyzed runner sustained at an average of approximately 175 bpm, as well as ensuring appropriate cadence and effective stride length aligned with the runner's characteristics. These findings provide practical recommendations for runners and their coaches on how to use available technologies not only for the analysis of specific performances but also for the long-term monitoring of training processes. The ultimate goal is to maximize individual performance and minimize the risk of overtraining.
