Abstract

The purpose of the current study is to examine the influence of 12-week yoga and walking exercise program on the carotid artery structure and function in the obese elderly women. And also this study relation examine physical function with change of the carotid structure and function. Subjects in this study are obese elderly women(over 30% body fat mass) and, the 16 subjects who consent to this study after listening the purpose of the study were selected. The exercise group performed the aerobic and yoga exercise training 12-week for 60 minutes 4 times a week. Exercise group after 12week, body fat mass(%), SBP and 10-m maximal walk time were significantly decrease and, $VO_2$max, $VO_2$max/weight, carotid artery luminal diameter(LD) and peak flow velocity(PFV) were significantly increase. The carotid artery IMT and EFV were no change after 12-week. Also, the change carotid artery LD and PFV were significantly relation with oxygen uptake and 10-m maximal walk time. In conclusion, 12-week aerobic and yoga exercise in the obese elderly women is effective to improve physical function, carotid artery structure and function, and change of the carotid artery LD and PFV had the significant correlation with change of physical function.

비만 고령여성을 대상으로 12주간 요가와 걷기운동의 실시에 따른 동맥혈관의 구조 및 기능에 대한 효과를 파악하고, 또한 운동에 의한 동맥혈관의 변화와 신체기능과의 관련성을 알아보고자한다. 비만 고령여성(체지방률 30%이상)을 16명을 대상으로 실시하였으며, 운동군은 1회 60분, 주 4회, 12주간 요가와 걷기운동을 병행하는 복합운동을 실시하였다. 운동군은 12주 후 체지방률(2.47%), 수축기혈압(3.88 mmHg), 최대보행시간(0.64초)가 각각 유의하게 감소하고, 최대산소섭취량(121.75 ml/min)과 체중당 최대산소섭취량(3.23 ml/kg/min)은 각각 유의하게 증가하였다. 경동맥 내경(luminal diameter; LD)는 0.03 cm가, 최고 수축기혈류속도(peak flow velocity; PFV)는 11.68 cm/sec가 각각 유의하게 증가하였으며, 경동맥 내중막두께와 확장말기 혈류속도(end-diastolic flow velocity; EFV)는 변화가 없었다. 경동맥 LD와 PFV는 체중당 산소섭취량, 최대보행시간과 유의한 관계가 나타났다. 따라서 12주간의 요가와 걷기운동은 비만 고령여성들의 신체기능, 경동맥 구조와 기능을 개선시키는데 효과적인 것으로 나타났으며, 또한 경동맥 내경과 최고수축기 혈류속도의 변화가 신체기능의 변화와 관련이 있는 것으로 나타났다.
