Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Participants
Participants in the sham intervention group were not aware they they were not performing the IET intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

IET

Participants allocated to this arm performed 4 weeks of isometric wall squat exercise training, 3 times per week.

Group Type EXPERIMENTAL

Isometric exercise training

Intervention Type OTHER

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.

Sham

Participants allocated to this arm performed 4 weeks of isometric wall squat training, but the training prescription was intentionally provided at an insufficient intensity to achieve any physiology stimulus.

Group Type SHAM_COMPARATOR

Isometric exercise training

Intervention Type OTHER

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.

No intervention control

Participants allocated to this arm did not perform any exercise and were required to maintain usual daily habits.

Group Type NO_INTERVENTION

No interventions assigned to this group
