However, little researchhas been conducted into the running cycle as concerns female runners. The aim of this study is to analyse, in women runners, therelationships between spatiotemporal parameters in the running cycle, the heel drop in running shoes and a progressive increase intraining speed, when running on a treadmill.Thirty-eight female runners were recruited from the Malaga University Athletics Club and Nerja Athletics Club. All were at least 18years old, recreationally active (3–4 running sessions per week) and able to run 5kmin less than 25min. Their running performance ona treadmill was recorded and spatiotemporal parameters assessed using the OptoGait system.As the running speed increased (8–12–15km/h) the spatiotemporal parameters of the running cycle altered: the flight timeincreased (P<.001) and the contact time decreased (P=.05). Heel drop (4–12mm) was not significantly associated with any of theparameters (phase 1: P=.198; phase 2: P=.191; phase 3: P=.242).A progressive increase in training speed on a treadmill directly influences the spatiotemporal parameters of the running cycle inwomen runners.
