Feasibility and Acceptability of Isometric Exercise and Lifestyle Change for the Management of Hypertension

High blood pressure (hypertension) is a leading risk factor for cardiovascular diseases and may contribute to poor health and premature death. The purpose of this research is to learn if a home-based isometric exercise programme combined with lifestyle change advice is a practical and acceptable method for people diagnosed with hypertension to manage their condition. Isometric exercise involves a muscle contraction without movement of the limbs and previous research has shown this may be effective for reducing blood pressure. Therefore, this study will explore the experiences, thoughts, attitudes, and barriers to participation. It will also examine the effect the isometric exercise has on blood pressure. Participants will undertake an isometric exercise programme using a wall squat position, 3 times per week, for 12 weeks. The exercise sessions will be completed at home with remote online supervision by an exercise professional. Lifestyle change advice will given in line with current guidelines to promote healthy behaviours to reduce high blood pressure. After 12 weeks, participants will be encouraged to continue with the wall squat exercise for a further 12-weeks unsupervised. Throughout the study, participants' blood pressure and daily activity will be recorded using a smartwatch device. Upon completion of the intervention period, participants will be interviewed to gather their views and opinions on the isometric exercise programme. Changes in blood pressure will be evaluated at 12 and 24 weeks. By exploring whether an isometric exercise programme is a feasible and acceptable method for hypertensive people to manage their condition and how this influences blood pressure, this research may aid in the development of a strategy to manage hypertension.
