The purpose of this study is to determine whether adding load to slow controlled breathing training could enhance blood pressure lowering in patients with essential hypertension.
Hypertension (HT) is one of the major risk of cardiovascular diseases and cost of pharmacological treatment is a very high. Lifestyle modification is the first trial in stage 1 hypertension before commencing pharmacological treatment and a co-treatment with drug in hypertensive patient. Slow paced breathing training and physical training has been shown to reduce both systolic and diastolic blood pressure in HT. Moreover loaded breathing was reported to be able to decrease blood pressure in healthy. Loaded slow breathing training may enhance the antihypertensive effect of slow paced breathing.
