Efficacious stroke rehabilitation depends not only on patients' medical treatment but also on their motivation and engagement during rehabilitation exercises. Although traditional rehabilitation exercises are often mundane, technology-assisted upper-limb robotic training can provide engaging and task-oriented training in a natural environment. The factors that influence engagement, however, are not fully ...

An acute reduction in blood pressure observed after a single bout of exercise is termed post-exercise hypotension (PEH). In contrast to moderate intensity aerobic exercise, little is known about the PEH response following high-intensity interval exercise. The present purpose is to assess how sex and training status impact PEH following ...

Regional anesthesia to attenuate skeletal muscle afferent feedback abolishes the exercise induced increase in middle cerebral artery mean blood velocity (MCA Vmean). However, such exercise related increases in cerebral perfusion are not preserved during post-exercise muscle ischemia (PEMI) where the activation of metabolically sensitive muscle afferents is isolated. We tested ...

Rating of perceived exertion (RPE) is increasingly being considered a viable tool beyond its original use for monitoring in-task exercise intensity. Research indicates that anticipated, in-task, and post-exercise RPE values are often notably different from each other. An important new consideration is how perceptions are impacted by high-intensity interval training ...
