若年女性の下肢筋力の現状と下肢筋力低下に関連する生活習慣因子を明らかにすることを目的として、山口県立大学の女子学生55名を対象とし、本研究を実施した。30秒椅子立ち上がりテストCS-30テスト）による下肢筋力測定の結果、標準未満に該当する女子学生が約2/3を占めていた。下肢筋力が低下している学生では、1日8,000歩以上歩いている割合と3メッツ以上の歩行を20分以上行っている割合がいずれも有意に低く、健康維持のための運動実施を自覚している割合も有意に低かった。若年女性の下肢筋力低下防止のためには、歩行習慣と健康意識が重要であることが示唆された。
The purposes of this study were to understand the current situation of lower-extremity weakness in young women and to identify the lifestyle factors associated with the lower-extremity weakness. The subjects were 55 female students in Yamaguchi Prefectural University. Lower extremity muscle strength assessed by 30 second Chair Stand Test were below average in about two thirds of the students. Both percentages of students who used to take more than 8,000 steps a day and those who used to walk at more than 3 METs for more than 20 minutes were significantly low in the students with lower-extremity weakness. Percentage of students who were aware of exercises to maintain good health was also significantly low in those students. Our results suggest that walking habit and health consciousness may be important for the prevention of lower-extremity weakness in young women.
