This ebook tells about This study was designed to explore the relationship between circadian rhythm of exercise and benefit on arterial blood pressure. There are known variations in cardiovascular response to exercise attributed to the circadian cycle. Exercise prescription, however, currently does not include a specified time of day. This study investigates the relationship of timing of day of regular aerobic exercise for optimal blood pressure response. A total of 22 participants exercised on stationary bicycles for 8 weeks in one of three groups 7AM (n=9), 12 PM (n=5) and 6:30 PM (n=9). Preintervention 24 hour ambulatory blood pressure readings, cardiorespiratory fitness, and anthropometric measurements were compared to those of post-intervention. ANOVA was used to examine any mean differences between the three groups in baseline 24-hour ambulatory systolic, diastolic and mean arterial blood pressures. ANOVA was used to determine if any significant differences existed between the mean change (posttest - pretest values) of each of the three groups. Paired t-tests were used to detect any statistically significant within group changes in anthropometric or cardiovascular changes for all participants (regardless of group) over the eight weeks of the protocol. This study did not find any statistically significant differences for effects of exercise on change in 24-hr ambulatory blood pressure measurements as a function of time of day of exercise. Absolute differences found were of clinical importance (2.88 in AM vs. 0.89 in PM). Findings provide evidence that exercise at a particular time of day might give greater results in blood pressure improvement. A larger absolute decrease found for the morning change in SBP vs. evening change in SBP (i.e. 2.88 mm Hg vs. 0.89) is consistent with the original hypothesis. Compliance was an issue in this pilot efficacy study. Participation in all sessions also varied among subjects. From these findings, however, it seems very likely that time of day may be an important when prescribing exercise to a normotensive and/or a hypertensive individual. This study supports the general AHA and AGSM recommendations for minimum aerobic exercise for blood pressure improvement. This study concurs the need for early lifestyle modifications to postpone/prevent development of hypertension.
