One-minute bursts of high-intensity interval training were more effective than conventional moderate, continuous exercise for improving aerobic fitness after stroke.
Repeated 1-minute bursts of high-intensity interval training are more effective than conventional moderate, continuous exercise for improving aerobic fitness after stroke, according to a multicenter randomized controlled trial.
The traditional MICT protocol for stroke rehabilitation targeted 40% HRR for 20 minutes and progressed by 10% HRR and 5 minutes every 4 weeks, up to 60% HRR for 30 minutes.peak) improved twice as much as those of the MICT group: 3.5 mL of oxygen consumed in 1 minute per kg of body weight compared with 1.8 mL/kg/min.peak from baseline remained above the clinically important threshold of 1.0 mL/kg/min at 8-week follow-up in the HIIT group but not in the MICT group .
On average, the HIIT group spent 36% of total training time exercising at intensities > 80% HRR throughout the intervention, while the MICT group spent 42% of time at intensities of 40%-59% HRR. Nevertheless, the authors concluded,"Given that a lack of time is a significant barrier to the implementation of aerobic exercise in stroke clinical practice, our findings suggest that short-interval HIIT may be an effective alternative to traditional MICT for improving V̇O"Our findings show that a short HIIT protocol is possible in people with stroke, which is exciting to see," said Tang.
