Distance Other studies have attempted to measure the effect of distance on blood pressure response to determine if there is a correlation between distance and a significant reduction in blood pressure . One of these studies (see Moreau et al, 2001) involved 24 sedentary postmenopausal American women (15 in the intervention group) with high blood pressure. The results showed that after a 2-year walking program, there was a statistically significant drop of 13 mmHg in systolic blood pressure in participants who took antihypertensive medication and 11 mmHg in those who did not receive medication. while there was no difference found between their diastolic blood pressure and that of the control group. Participants in the intervention group were asked to walk 3 km per day in addition to their normal daily physical activity. After the first year, the reduction in blood pressure was significant: 6 mmHg in the systolic blood pressure of participants who took antihypertensive medications and 7 mmHg in the group without medication. In this study, the magnitude of reduction in systolic blood pressure was significant. Blood pressure resulting from a walking program is similar to that found in previous studies in response to traditional exercise (see Seals et al, 1997 and Hagberg et al, 2000). Frequency Several studies have examined the impact of frequency. of walking per week on blood pressure to determine which frequency is most effective in terms of response to blood pressure reduction. A study by Gettman et al, conducted in 1976, which compared the effect of brisk walking between one, three and five days per week. week on blood pressure response, found that the frequency difference was not ...... middle of article ...... effect on systolic blood pressure only. Lee et al (2010) found that moderate to high intensity waking was more likely to decrease blood pressure than low intensity walking. This result confirms the conclusions of the study conducted by Quinn in 2000. Nemoto et al (2007) compared the effect of continuous walking at moderate intensity (50% of maximum aerobic capacity) and interval walking at high intensity (70% of maximum aerobic capacity). aerobic capacity) on the reduction of blood pressure. They found that the reduction in blood pressure was greater in the group that walked at high intensity: 9 mmHg for systolic blood pressure and 5 mmHg for diastolic blood pressure. The results of a study conducted in India by Gosh (2006) to measure the effect of walking intensity (2 km/30 min) for 20 weeks, showed a significant reduction in systolic/diastolic blood pressure of approximately 10 mmHg/4 mmHg.
