Abstract

This study was conducted by walking analysis for 35 middle aged females, consisting of 19 females having own right carrying habit, and 16 females having left one.

First, as the choice of handbag, the MCM brand which career women are the most preferred brand is chosen and, the form is upright square in figure, and the length of shoulder strap is both the type of handles and shoulder-length. After measuring the average body weight of subjects, the weight of handbag is determined by the 5%(3.1kg) of average body weight, the 10%(5.6kg), the 15%(8.1kg). Also, the types of carrying methods are classified into 5 positions, 1) None 2) Left hand, 3) Left shoulder, 4) Right hand, 5) Right shoulder, and the shoulder-length is located in iliac crest. To measure stride length, step length, step width, the gait lead time, WalkWay MG-1000(Anima co., Japan), analysis equipment, was used. Through sufficient gait practice and stretch before gait, in the experiments, we drove subjects to do natural gait, and they wore comfortable their own sportswear. Also, they walked right foot first in with their socks. The results of walking analysis as follows:

1. The results of stride length according to the increased handbag weight decreased at the whole groups, and showed significant difference(p< .05) at the right carrying habit group. The results of stride length according to the foot supported body weight showed that left foot shows the highest figure, and right foot shows the lowest. The results of stride length according to handbag carrying methods by increased weight decreased at the right carrying habit group, showed non-uniform at the left carrying habit group.

2. The results of step length according to the increased handbag weight decreased at the whole groups, and showed significant difference(p< .05) at the right carrying habit group. The results of step length according to the foot supported body weight showed that left foot shows the highest figure, and right foot shows the lowest. The results of step length according to handbag carrying methods by increased weight decreased at the right carrying habit group, showed non-uniform at the left carrying habit group.

3. The results of step width according to the increased handbag weight showed decreasing tendency at the right carrying habit group, and decreasing tendency at the left carrying habit group. The results of step width according to the foot supported body weight showed that left foot shows the highest figure, right foot shows the lowest, and showed significant difference(p <.05) at the whole group. The results of step width according to handbag carrying methods by increased weight showed non-uniform at the whole group.

4. The results of gait lead time according to the increased handbag weight increased and showed significant difference(p< .05) at the whole groups. The results of gait lead time according to the foot supported body weight showed that left foot shows the longest figure, right foot shows the shortest, and showed significant difference(p< .05) at the whole groups. The results of gait lead time according to handbag carrying methods by increased weight increased at the whole group, and showed significant difference(p< .05) at the right carrying habit group.
