Abstract

The purpose of this study is to identify the characteristics of both backward walking (BW) and backward running (BR) and show the differences between two kinds of movements according to age. One 'hundred and four primary school children and varsity 20 students participated in this study. The SUbjects were divided into four groups. 15-meters-long lane was used in this experiment. All video pictures were manually digitized on Sony Motion Analyzer (SMC-70G). Cycles of motion in BW &BR were analyzed. The walking velocity didn't increase so with age in BW-test, but the results of BR-test revealed that running velocity increased with age. Step length was increased with age in each test. Step frequency of BR didn't increase with age. Step frequency in BW didn't increase with age. We categorized the form using examples from Miyamaru's procedure. BW was categorized to 5 patterns, and BR divided to 6 patterns.
