Key result
HIIT is associated with ~83% fewer SBP non-responders in prehypertensive versus normotensive women.
Why the study?
There is wide interindividual variability in response to exercise on blood pressure and cardiometabolic risk factors that has not been explored in populations at risk for hypertension.
Does a 16-week HIIT program reduce blood pressure and what is the prevalence of non-responders in prehypertensive versus normotensive overweight/obese women?

Absolute Event Rate: 11.4% vs 68.8%
p-value: p=<0.0001
A 16-week HIIT program significantly reduces systolic blood pressure in prehypertensive overweight/obese women, with baseline SBP being the strongest predictor of response and a lower prevalence of non-responders compared to normotensive women.
No takes yet. Share an insight, caveat, or question.
HIIT may yield more consistent BP reductions in prehypertensive women; leaves open confirmation of predictors and effects in randomized trials.
Álvarez et al. (2018) studied Prehypertension and overweight/obesity (n=84). High-intensity interval training (HIIT) vs. Normotensive women undergoing the same HIIT program was evaluated on Prevalence of non-responders based on systolic blood pressure (p=<0.0001). After 16 weeks of high-intensity interval training, prehypertensive women had a significantly lower prevalence of non-responders for systolic blood pressure reduction compared to normotensive women (11.4% vs. 68.8%, p<0.0001).
