One-minute, short bursts of high-intensity interval training for 19 minutes may be more effective for improving fitness among people six months or more after a stroke than traditional, 20–30 minutes of moderate-intensity exercise sessions, according to research.
The multi-site trial took place between September 2018 and March 2024 and included stroke survivors between six months to 5 years after a stroke. Researchers randomly grouped participants to receive either three days per week of 12 weeks of high-intensity interval training or three days per week of 12 weeks of traditional moderate exercise sessions. The high-intensity interval training protocol involved ten 1-minute intervals of high-intensity exercise, interspersed with nine 1-minute low-intensity intervals, for 19 minutes total. The moderate intensity continuous training involved 20 to 30 minutes of steady exercise at moderate intensity.
Researchers then compared fitness levels, cardiovascular risk factors such as blood pressure and stiffness of blood vessels, walking speeds and distances between the two groups.
Researchers found:
The high-intensity interval training group's cardiorespiratory fitness levels (rate of oxygen consumed at peak exercise) improved twice as much as the moderate intensity continuous training group.
The improvement in the high intensity interval training group stayed above clinically important thresholds even at the 8-week follow-up.
Said Ada Tang, Ph.D., "We used an adaptive recumbent stepper, which we believe allowed more people to participate in high-intensity interval training, even those who cannot walk fast enough or long enough on a treadmill."
The limitations of the study include that study participants were higher functioning stroke survivors from a physical standpoint who were at lower risk for heart disease.

HIIT is a better way to exercise on most measures, except for endurance. However, I find most people doing endurance are just wasting their time, because they don’t do it intensely.
i.e. go out in the woods and get chased by a bear.
just make sure the bear is on board for the rest periods
Does the gender of the Bear matter? //
I would find it unbearable.
Wonder how it is for stroke prevention?...love my 3x week HIIT on an Elliptical
.
Short, intense bursts of exercise more effective after stroke than steady, moderate exercise
If it doesn’t kill you.
I go from 117 to @170 bpm...maintaining @155 bpm for 2 min at a time...seems to have made my heart stronger
