comparative effects of mild and moderate aerobic exercises on bp, vo2 and hr in hypertensive patients

Conditions: Hypertension

Summary: world health organization, when systolic blood pressure is equal to or above 130 mm hg and/or a diastolic blood pressure equal to or above 85 mm hg , the blood pressure is considered to be raised or high is called hypertension." most people with hypertension have no symptoms at all; this is why it is known as the "silent killer". more than 1 in 5 adults worldwide had raised blood pressure. there has been studies on strength exercise, severe aerobic exercise and other types of exercises and on their effects on blood pressure, heart rate and oxygen saturation in other patient populations and on healthy individuals as well, but in the patients with hypertension no comparison has been made between mild and moderate aerobic exercise (tread mill) yet, stating which one is effective. secondly, already present studies have shown long term effects mostly, not the comparative effects of mild and moderate exercises on blood pressure heart rate and oxygen saturation of patients with hypertension. these techniques are inexpensive, easy to perform and contain no known harmful effect. hence, current study will undertake this task of finding out what are the comparative effects of mild and moderate aerobic on the bp, heart rate and oxygen saturation and secondly which technique is more effective. study design will randomized clinical trial with non-probability convenient sampling. it will be single blinded study with blinding of assessor. sample size was calculated from epitools website and will be 28. there will be two groups which will be randomly assigned 14 people using lottery method. data will be collected from community dwelling areas of lahore patients with hypertension with systolic blood pressure 130 - 159 mmhg and diastolic blood pressure 85 - 99 mmhg (pre hypertensive and stage 1), 30 to 50 years of age, patients who have taken any antihypertensive medicine in more than 6 hours and both males and females will be recruited. tools will be aneroid sphygmomanometer for measuring blood pressure and pulse oximeter for measuring oxygen saturation and heart rate and post interventional bp, heart rate readings and oxygen saturation will be taken for both groups on the same day. post intervention blood pressure, heart rate and oxygen saturation will be taken after 5 minutes.
