Abstract

The aim of this study was to determine the effects of tote bag weight on muscle thickness of pectroalis minor and tone of upper trapezius in young adult women. 27 women habitual of carrying tote bags. The subjects were measured the tone of the upper trapezius muscle and the thickness of the pectoralis minor muscle while carrying tote bags with the weight of 0%, 5%, 7.5% and 10% of the subjects' body weight. As the weight load increased, the upper trapezius muscle demonstrated significantly increased muscle tone (p<.05). additionally, a significantly increased thickness in the pectoralis minor muscle was noted(p<.05). These findings suggest that the habit of carrying a tote bag on the wrist may be disadvantageous to improving the two muscles in young women. Therefore, this study recommend women who likely used tote bag decrease the weight of the bag.
