Influence Of Air Resistance On Ground Reaction Forces During Treadmill Running, Jared Steele, Iain Hunter

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: Running is fundamentally driven by forces applied to the ground, eliciting ground reaction forces (GRFs) which accelerate the runner. These GRFs are divided into vertical, anteroposterior, and mediolateral components. As running speed alters, so do the patterns of these forces. By juxtaposing these GRF patterns with metabolic data, we can discern how movement patterns adapt across different running conditions. One of the key distinctions between treadmill and overground running is the influence of air resistance. METHODS: The study involved twenty-four active male runners experienced in achieving a sub-17-minute-5km or equivalent performance. The main objective was to examine the influence …
