계절에 따른 대기오염 차이가 고령자의 체구성 성분 및 순환기능, 체력에 미치는 영향

Abstract

The purpose of this study was to investigate the effects of high air pollution season and low air pollution season on body composition, cardiovascular function(blood pressure, heart rate) and physical strength. Eight women with an average age of 76 years participated in this study, and each variable was measured in December, a season with high air pollution, and September, a season with low air pollution. Healthy subjects without disease were selected as study participants. Measurement items were body fat, muscle mass, and BMI, which are body composition components. Cardiovascular function was defined as blood pressure and heart rate. Physical strength was measured as grip strength. As a result, in the case of body composition BMI, the season with high air pollution was significantly higher than the season with low air pollution (p.05). There was no significant difference in blood pressure and heart rate. In the case of grip strength, which is physical strength, the season with high air pollution was significantly lower than the season with low air pollution (p.01). In conclusion, it was found that accounts with high air pollution increased BMI and decreased physical strength.
