Abstract
Background
Sprint performance is determined by a complex interaction of mechanical, neuromuscular, and technical factors. Although maximal running speed plays a key role in sprinting, fundamental movement patterns are also revealed at submaximal speeds. The aim of this study was to determine the relationships between running biomechanical parameters measured at different submaximal speeds (10–22 km/h) and the athletes’ performance level, as well as their personal bests in the 100 m and 200 m events.
Methods
The study included 40 sprinters of different ages and performance levels. Spatiotemporal parameters (Stance Phase, Step Width, Stride Length, Stride Time, and Cadence) were recorded at four controlled speeds, and the relationships were analyzed using linear mixed models accounting for repeated measurements, inter-individual variability, and the athletes’ age and height. Depending on the analyzed parameter, linear and quadratic effects of running speed were considered. Separate regression analyses were also performed to assess the relationships between biomechanical parameters and personal bests in the 100 m and 200 m events.
