Key result
Eight weeks of resistance training and high-intensity interval training decreased the proportion of systolic blood pressure non-responders from 46% to 38% and 69% to 46%, respectively.
Why the study?
The study evaluated the effects of resistance training and high-intensity interval training on blood pressure and compared their efficacy in reducing non-responders over four and eight weeks in hypertensive older adults undergoing pharmacological therapy.
Do resistance training and high-intensity interval training reduce blood pressure in hypertensive older adults on pharmacological therapy?
Do resistance training and high-intensity interval training reduce blood pressure in hypertensive older adults on pharmacological therapy?
p-value: p=< 0.05
Both 8 weeks of resistance training and high-intensity interval training effectively reduce systolic blood pressure and the prevalence of non-responders in hypertensive older adults.
Supports adjunctive RT or HIIT for SBP control in treated older hypertensives; leaves open confirmation of non-responder reduction in randomized trials.
BACKGROUND: This study evaluated the effects of resistance training (RT) and high-intensity interval training (HIIT) on systolic (SBP) and diastolic blood pressure (DBP) in hypertensive older adults undergoing pharmacological therapy over four and eight weeks. We compared the efficacy of RT and HIIT in reducing non-responders (NRs) between weeks 4 and 8 and analyzed time-course adaptations in NRs and responders (Rs). METHODS: = 13) groups. RT utilized elastic bands, and HIIT involved cycle ergometers, with three weekly 30 min sessions for 8 weeks. SBP and DBP were measured before intervention and at weeks 4 and 8, respectively. Individual responses were classified as NRs or Rs using the Hopkins method (SDIR = √[SDExp2-SDCon2]). Time-course adaptations were evaluated. RESULTS: < 0.05). The proportion of NRs for SBP decreased from 46% to 38% in RT-G and 69% to 46% in HIIT-G. Rs showed a peak SBP reduction at 4 weeks (-14.7 and -25.5 mmHg), stabilizing by week 8 (-22.8 and -19.6 mmHg) in RT-G and HIIT-G, respectively. CONCLUSION: Eight weeks of RT and HIIT effectively reduced SBP and NR prevalence, with time-course adaptations favoring Rs.

Cano-Montoya et al. (2025) studied Hypertension. Resistance training (RT) and high-intensity interval training (HIIT) vs. Active comparator (RT vs HIIT) was evaluated on Reduction in systolic and diastolic blood pressure and proportion of non-responders (p=< 0.05). Eight weeks of resistance training and high-intensity interval training decreased the proportion of systolic blood pressure non-responders from 46% to 38% and 69% to 46%, respectively.
