Description
Jopek, Krzysztofik, Mroczek, Zajac, and Mackala study how sprint step patterns vary across repeated runs, and how that links to hamstring injury risk. Eighteen male Polish national team sprinters, nine elite and nine sub-elite, each ran four 50 meter sprints. Their 2025 study also surveyed the athletes on past injuries.
Elite sprinters ran faster with quicker steps and shorter ground contact, a steadier pattern overall. About 89 in 100 athletes reported a past hamstring injury, mostly late in the swing or near the end of the run. Injuries clustered in the fourth repeat, pointing to fatigue. Sub-elite runners leaned on longer steps instead, with more variation the authors link to higher risk.
