A disruption in the spinal cord, such as following a spinal cord injury (SCI), can lead to deficits in motor and sensory function as well as lead to increased risk for secondary health complications such as muscle atrophy, pulmonary function deficits, cardiovascular disease, cognitive decline, and dysregulation of blood pressure (BP) resulting in chronic hypotension or periods of robust pressure fluctuations (i.e., autonomic dysreflexia and orthostatic hypotension). Traditional therapies to counteract these complications can be limited and commonly prescribed medications can have unwanted side effects. Thus, the purpose of the present study was to 1) examine the impact of ventilatory muscle training (VT) on BP regulation and cerebral tissue oxygenation during orthostasis and 2) examine the acute effects of electrically stimulated (ES) cycling on cerebral tissue oxygenation. Four individuals with paralysis completed eight weeks of VT and an orthostatic test was completed before and after training. VT led to an improvement in maintenance of mean arterial pressure as well as cerebral tissue saturation during orthostatic challenge. These findings warrant further investigation of VT or the improvement in BP dysregulation during daily orthostasis and influence on cerebral function. Nine individuals with paralysis completed an acute interval session of ES cycling consisting of five bouts of 2-minute exercise. During ES cycling there were observed increases in cerebral oxygenated and total hemoglobin, muscle deoxygenated hemoglobin, heart rate, and cardiac output. Additionally, ES cycling should be further investigated for its acute influence on cerebral function and training impacts for cerebral health.
