RT Journal Article T1 Influence of speed and heel-to-toe drop in running shoes for female recreational runners: A cross-sectional study. A1 Gijon-Nogueron, Gabriel A1 Soler-Crespo, Francisco Jose A1 Sanchez-Rodriguez, Raquel A1 Cabello-Marique, David A1 Lopezosa-Reca, Eva A1 Ortega-Avila, Ana Belen AB In recent years, the popularity of running has boomed and the number of women runners has risen sharply. However, little research has been conducted into the running cycle as concerns female runners. The aim of this study is to analyse, in women runners, the relationships between spatiotemporal parameters in the running cycle, the heel drop in running shoes and a progressive increase in training 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 18 years old, recreationally active (3-4 running sessions per week) and able to run 5 km in less than 25 min. Their running performance on a treadmill was recorded and spatiotemporal parameters assessed using the OptoGait system.As the running speed increased (8-12-15 km/h) the spatiotemporal parameters of the running cycle altered: the flight time increased (P  YR 2019 FD 2019 LK http://hdl.handle.net/10668/13946 UL http://hdl.handle.net/10668/13946 LA en DS RISalud RD Apr 5, 2025
