Subgroups of foot-ankle movement patterns can influence the responsiveness to a foot-core exercise program: a hierarchical cluster analysis

Demographic, anthropometric and running practice data from asymptomatic runners that participated in a randomized controlled trial testing the effects of an 8-week foot-core training program.Kinematic data include the joint angles of foot and ankle joints during the stance phase of running (normalized by stance phase time and averaged across steps) from baseline and week-8 assessment.Kinematic time-series data also included for each step (time-normalized by stance phase).
