The Kinematic Characteristic Study on Pupils Walk with Heelys

摘要

The purpose of this study was to compare the gait between primary school students walking with sneakers and Heelys. Kinematic indexes were gathered when pupils wore sneakers, closed-wheel Heelys (CWH) and open-wheel Heelys (OWH). A high-speed camera was used in this experiment to shoot the children's gait at sideline when they were walking in the three kinds of condition. Step length, stride frequency, walking velocity and landing angle were chosen as indexes in normal walking to analysis. Statistics showed that wearing sneakers had the longest step length while the shortest with OWH. Stride frequency, walking velocity, landing angle presented a decreasing trend after wore sneakers, CWH and OWH. Significant different (P<0.01) was all found in step length, stride frequency, walking velocity and landing angle.
