高齢女性の下腿三頭筋における皮膚冷刺激付加の短期的低強度筋力トレーニングの効果

抄録

  The purpose of this study was to verify the effect of short-term low load strength training with skin cooling on the triceps surae bilaterally with loading. Twenty-two elderly women participated in this study and were divided into two groups, skin cooling and control. Subjects performed 30 repetitions of the exercise task cycle more than two times per week for 6 weeks. The exercise task cycle consisted of a heel raise (concentric phase) at fast speed (~1s) and a heel drop (eccentric phase) at slow speed (3s) bilaterally while standing. In the skin cooling group, cutaneous stimulation consisted of the application of 5% menthol gel to the skin above the triceps surae on both legs. MVC significantly increased in both control and skin cooling by 22.0% and 28.9%, respectively. Post intervention MVC was significantly greater in the skin cooling group than in the control group. These results suggest that short-term low load strength training with skin cooling can be an effective method for increasing muscle strength with potentially less fatigue.
