Endurance training has documented effect on blood pressure in hypertension. However, only low to moderate training intensity has so far been studied. Higher aerobic intensity based on individual measurements of maximum oxygen uptake is more efficient in increasing oxygen uptake, and might prove more effective in lowering blood pressure. Group training, on the other hand is not individualised, but less personnel required and may prove more cost effective. Endurance training is shown to improve both systolic and diastolic left ventricular function, as well as endothelial function. Both can be measured non-invasively by ultrasound.
