유산소 운동 시 마스크 타입에 따라 호흡 기능에 미치는 효과

Abstract

Purpose: This study aimed to explore the effects of the type of mask worn during aerobic exercise on respiratory function. Methods: A total of 30 people were included in this study. The subjects were randomly assigned to two groups: the dental mask group (wearing dental masks during aerobic exercise, n=15) and the KF94 mask group (wearing KF94 masks during aerobic exercise, n=15). Aerobic exercise was performed using a sedentary cycle with eight levels of intensity control three times a week for 4 weeks. Respiratory function (forced vital capacity [FVC], forced expiratory volume in one second [FEV1], FEV1-to-FVC ratio [FEV1/FVC%], and peak expiratory flow [PEF]) was assessed using a spirometer at 0, 2, and 4 weeks. Results: A significant difference in all respiratory function parameters, including FVC, FEV1, FEV1/FVC%, and PEF, was observed between the two groups (p<.05). The change in respiratory function was not statistically significantly different between the two groups. However, a significant difference in the amount of change in PEF was observed between the two groups at 4 weeks (p<.05). Conclusion: The dental and KF94 mask groups showed increased respiratory function. However, no significant difference was observed between the two groups. Furthermore, no difference was observed in the amount of increase in respiratory function during aerobic exercise according to the mask type. Thus, we recommend wearing a dental mask that is easy to breathe during aerobic exercise.
