ABSTRACT
BACKGROUND:
The hypotensive effects of high-intensity interval training have been reported; however, studies on older adults are few. This study aimed to examine whether interval-walking training (IWT), a home-based program of high-intensity interval training, reduces blood pressure (BP) levels when compared with a non-intervention group in community-dwelling older adults.METHODS:
An intervention study was conducted with 55 men (age, 75±5 years; IWT/control groups, N.=27/28) and 100 women (75±5 years; N.=47/53). The IWT regimen was as follows fast (high-intensity) walking at 70-85% of the peak aerobic capacity and normal (light-intensity) walking at approximately 40% of the peak aerobic capacity for 3 min each, ≥5 times/walking day, and ≥4 days/week for 5 months. Systolic, diastolic, and mean arterial BPs (SBP, DBP, and MAP, respectively) were measured in the supine posture.RESULTS:
The mean baseline SBP/DBP was 132/78 mmHg in men and 131/72 mmHg in women. Five-month changes in SBP, DBP, or MAP did not significantly differ between the IWT and control groups in either sex. The weekly fast-walking time in the IWT group was negatively correlated with changes in DBP (Spearman's ρ=-0.383, P=0.049) and MAP (ρ=-0.444, P=0.021) only in men.CONCLUSIONS:
Though present findings did not indicate significant hypotensive effects of IWT in community-dwelling older adults, men with longer fast-walking times experienced greater BP decreases. Further studies with sufficient sample sizes are needed to determine the factors modulating the effects of the proposed training program.
