The purpose of this study was to examine the preventive effects of exercise on postprandial blood pressure fall in the elderly who had undergone postprandial hypotension. After the informed and written consent, 19 elders from a community center and a nursing home participated in 2 separate interventions; rest after meal and 10 minutes leg exercise with 10 minutes walking after meal using within subject repeated measures design. Blood pressure and heart rate were measured before the meal as baseline and then 15 minutes intervals from immediately after meal till 90 minutes after meal. Data were analyzed by descriptive statistics, repeated measures of ANOVA, paired t-test with Bonferroni adjustment using the SPSS 14.0. There was no significant fall of blood pressure after exercise, whereas significant fall of postprandial systolic and diastolic pressure were shown in the rest after meal group by 18.7±7.7/9.0±7.7mmHg respectively compared with baseline blood pressure. Incidence of PPH was significantly lower in the exercise group than the rest group. Exercise after a meal should be recommended for the elderly who had experience of postprandial hypotension. However, specific types and duration of exercise should be investigated using more controlled study design.
