High-Intensity Interval Training After Stroke: An Opportunity to Promote Functional Recovery, Cardiovascular Health, and Neuroplasticity
Objectives. To provide an updated review of HIIT poststroke through (a) synthesizing current evidence; (b) proposing preliminary considerations of HIIT parameters to optimize benefit; (c) discussing potential mechanisms underlying changes in function, cardiovascular health, and neuroplasticity following HIIT; and (d) discussing clinical implications and directions for future research.
Results. Preliminary evidence from 10 studies report HIIT-associated improvements in functional, cardiovascular, and neuroplastic outcomes poststroke; however, optimal HIIT parameters remain unknown.
Conclusion. Larger randomized controlled trials are necessary to establish (a) effectiveness, safety, and optimal training parameters within more heterogeneous poststroke populations; (b) potential mechanisms of HIIT-associated improvements; and (c) adherence and psychosocial outcomes.
