Key result
Higher-intensity interval exercise attenuated the resting increase in pulse wave velocity in older adults regardless of fitness level compared to control (P<0.001).
Why the study?
Does moderate or higher-intensity exercise improve post-exercise arterial stiffness in older adults compared to no exercise?
RCT
randomised order
Does moderate or higher-intensity exercise improve post-exercise arterial stiffness in older adults compared to no exercise?
p-value: p=<0.001
Higher-intensity interval exercise attenuates the resting increase in arterial stiffness in older adults regardless of fitness level, whereas moderate-intensity exercise only benefits those with higher baseline fitness.
May blunt arterial stiffening in older adults; extends prior work across fitness levels but remains hypothesis-generating.

Perissiou et al. (2018) conducted an RCT in older adults with varying fitness levels. Moderate-intensity continuous exercise and higher-intensity interval exercise vs. Control (no-exercise) was evaluated on Pulse wave velocity (PWV), augmentation index (AIx75) and reflection magnitude (RM) (p=<0.001). Higher-intensity interval exercise attenuated the resting increase in pulse wave velocity in older adults regardless of fitness level compared to control (P<0.001).
