McLeod KJ, et al. - This pilot clinical study was performed to assess the ability of a “passive” exercise regimen (noninvasive calf muscle pump stimulation) to normalize blood pressure in a chronically hypotensive elderly population and enhance cognitive function. Time to complete the executive function tests in the hypotensive group was almost twice that of the control group at the initiation of the study. For 1 hour/day, or less, daily calf muscle pump stimulation (passive exercise) was found to be sufficient to normalize diastolic blood pressure (DBP) and significantly improved performance on the executive function tests.
