Changes in rearfoot strike patterns over childhood

Rearfoot strike (RFS) in children running produces impact forces that give rise to a transient stress wave traveling through the body. It could contribute development of injuries. The purpose this study was determine RFS prevalence during childhood while at self-selected velocity prospective longitudinal cohort study. A total 175 (68 girls), aged 6 14 years, participated sample divided into three age groups (age 2016): 6-8 9-11 and 12-14 years which were analysed later (2019). 2D video-based used record Taking account all samples, jogging trial (an average both feet) 86.9% 2016 94.7% later; 82.6 94.4%, respectively. In samples significant increase found trials for feet over (jogging, left foot, p=.011, right p=.023; running, p=.001, p<.001). girls, there no differences any conditions. boys, after (p<.01) trial. This shows increases with results may be characterize typical population.
