We evaluated the effect of group training on endothelial function as measured byarterial reactivity to the cold pressor test (CPT). Eighteen elderly women were dividedinto the training (n=8， age=67.0+-2.7yrs) and control group (n=10， age=69.2+-6.5yrs).Subjects in the training group performed 90-min group training twice a week for 12 weeks.Each training program consisted of recreational activities，circuit training，and chair-basedexercise. Brachial systolic and diastolic blood pressure were obtained in the supineposition. CPT was performed by submersion of the left foot up to the ankle in ice slushfor 90 seconds. In order to measure the percentage change in artery diameter (△CA)between baseline and end of CPT，the left side of the common carotid artery was imagedusing an ultrasound system. After the training program， △CA was significantlyincreased (-0.4% to 1.4%，p< 0.05) without any changes in systolic/diastolic blood pressure.In control group，however，there were no significant differences during same duration.These finding suggest that short term group training improves the endothelial function inelderly women.
