A randomized, sham-controlled intervention measuring the effects of isometric exercise training (IET) on blood pressure and cardiac autonomics. IET has been proven effective in a plethora of randomized trials, but very little research has employed a sham-controlled design. This researched involved the recruitment of 30 participants who completed a 4 week IET intervention, sham control of the IET intervention, or a non-intervention control period. Pre and post blood pressure and cardiac autonomic measures were acquired and analysed. The hypothesis of this trial was a significant effect of IET on blood pressure, with no such effects following the sham control or normal control interventions.

A form of exercise involving static contraction against a wall, sustained for 2 minutes x4 sets per session. 3 sessions a week were required. The intensity was designed to achieve 95% of the participants maximum heart rate.
