Finger cold-induced vasodilation of older Korean female divers, haenyeo: effects of chronic cold exposure and aging

The aim of the present study was to evaluate the local cold tolerance of older Korean female divers, haenyeo ( N  = 22) in terms of cold acclimatization and ageing. As control groups, older non-diving females ( N  = 25) and young females from a rural area ( N  = 15) and an urban area ( N  = 51) part...

Description
Summary:The aim of the present study was to evaluate the local cold tolerance of older Korean female divers, haenyeo ( N  = 22) in terms of cold acclimatization and ageing. As control groups, older non-diving females ( N  = 25) and young females from a rural area ( N  = 15) and an urban area ( N  = 51) participated in this study. To evaluate local cold tolerance, finger cold-induced vasodilation (CIVD) during finger immersion of 4 °C water was examined. As a result, older haenyeos showed greater minimum finger temperature and recovery finger temperature than older non-diving females ( P
