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.

본 연구는 토트백이 젊은 여성의 작은가슴근 두께와 위등세모근의 긴장도에 어떤 영향을 미치는지를 확인하였다. 습관적으로 토트백을 들고 다니는 27명의 여성이 본 연구에 동원되었다. 대상자들은 대상자들의 체중의 0 %, 5 %, 7.5%, 10 % 무게에 해당하는 토트백을 한쪽 손목으로 들고 있는 동안 작은가슴근의 두께와 위등세모근의 긴장도를 측정하였다. 가방의 무게가 증가할수록 위등세모근의 긴장도는 유의하게 증가되었으며(p<.05), 작은가슴근의 두께 역시 가방 무게에 따라 유의하게 증가되는 것을 확인하였다(p<.05). 이러한 결과를 바탕으로, 손목으로 토트백을 드는 습관이 젊은 여성의 위등세모근과 작은가슴근에 해로운 영향을 끼칠 수 있다는 것을 확인하였다. 그러므로, 본 연구는 토트백 즐겨 사용하는 여성들에게 가능하다면 토트백 무게를 감소시킬 것을 제안한다.
