〔目的〕スタティックストレッチング(SS)と圧迫刺激による腓腹筋形状および足関節背屈可動域への影響を検討した.〔対象〕健常成人60名とした.〔方法〕刺激はSS群,圧迫群,併用群の三群とした.超音波診断装置とデジタルカメラ,筋弾性計を用いて計測された足関節背屈可動域,筋束長,筋腱移行部(Muscle Tendon Junction;以下,MTJ)の移動量,スティフネス,筋弾性を計測し三群間で比較した.〔結果〕足関節背屈可動域,筋束長,筋弾性は三群の平均に有意な差はないが,MTJの移動量はSS群より併用群で高い値を,スティフネスは併用群のみ刺激後に低い値を示した.〔結語〕SSと圧迫刺激の併用は,神経生理学的,力学的な要素の相乗効果により効率的に筋伸張性や柔軟性の向上を計ることができる.

BACKGROUND: Due to the COVID-19, it is recommended to wear a facemask. Mask-wearing may increase the physical burden during exercise. OBJECTIVE: This study aimed to compare the eff ects of a mask-wearing and ambient room temperature on heart rate( HR), autonomic nervous system activity, and rating of perceived exertion (RPE) during a bicycle exercise. METHODS: Thirty healthy university students participated in four bicycle exercise sessions, performed at the intensity of anaerobic threshold for 10 minutes. During these sessions, participants were subjected to two temperatures, 20℃ and 24℃ , and were either, while wearing a mask or not. We measured the electrocardiogram( ECG) and RPE during exercise. HR and rate of change in autonomic nervous system activity were evaluated by the ECG. RESULTS: We observed signifi cant changes in HR( p < 0.001) and RPE( p = 0.0026) between diff erent room temperatures and whether or not a mask was used. RPE was signifi cantly higher during mask-wearing sessions than during no mask sessions at 24℃ . However, there were no signifi cant changes in the rate of change in autonomic nervous system activity, regardless of room temperature or mask-wearing. CONCLUSION: Our results suggest that physiological discomfort associated with mask-wearing can be reduced by decreasing the ambient room temperature.
