Canterbury Christ Church University study links wall sits to blood pressure reduction

A randomized controlled study conducted by Canterbury Christ Church University has identified the optimal frequency for using wall sits to lower blood pressure. Published in BMJ Open Sport & Exercise Medicine, the research suggests that performing the isometric exercise three times per week provides the most significant and sustainable reduction in blood pressure.

The study involved 100 adults with an average age of 37 and systolic blood pressure levels between 120 and 140 mmHg. Participants did not have diagnosed hypertension or use blood pressure medication. During the initial four-week phase, training groups performed four two-minute wall sits per session, three times weekly. This resulted in a significant average reduction of 9.45 mmHg in systolic pressure and 5.47 mmHg in diastolic pressure.

In the subsequent four weeks, researchers tested different frequencies to determine how to maintain these effects. While one or two sessions per week showed some benefits, the effects diminished more quickly compared to the three-session group. The findings support a dose-response principle for isometric interventions in daily life to support cardiovascular health.
