DistanceOther studies have attempted to measure the effect of distance on blood pressure response to find out if there is a correlation between distance and a significant reduction in blood pressure. One such study (see Moreau et al, 2001) involved 24 sedentary post-menopausal American women (15 in the intervention group) with high blood pressure. The results found that, after a 2-year walking program, there was a statistically significant drop of 13 mmHg in systolic blood pressure in participants taking antihypertensive medications and 11 mmHg in those not taking medications, while there was no found no difference in diastolic blood pressure and blood pressure 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 systolic blood pressure in participants taking antihypertensive drugs and 7 mmHg in the group without drugs. In this study, the magnitude of reduction in systolic blood pressure as a result of 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 the frequency of walking per week on blood pressure to determine which frequency is most effective in terms of responding 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 a week on blood pressure response, found that the difference in frequency was not... . half of the document ...... effect on systolic blood pressure only. Lee et al (2010) found that moderate to high intensity walking was more likely to decrease blood pressure than low intensity walking. This result supports those of the study conducted by Quinn in 2000. Nemoto et al (2007) compared the effect of continuous moderate-intensity walking (50% of peak aerobic capacity) and high-intensity interval walking (70% of peak aerobic capacity). aerobic capacity) on the reduction of blood pressure. They found that the reduction in blood pressure was greater in the high-intensity walking group: 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, demonstrated that there was a significant reduction in systolic/diastolic blood pressure of approximately 10mmHg/4mmHg.
