Key result
Isometric exercise training of the legs and arms significantly reduced resting systolic blood pressure compared to controls (P<0.05), but orthostatic tolerance only increased after leg-training.
Why the study?
Does isometric exercise training of the upper or lower limbs reduce resting blood pressure and improve orthostatic tolerance in humans?
RCT (n=27)
Does isometric exercise training of the upper or lower limbs reduce resting blood pressure and improve orthostatic tolerance in humans?
p-value: p=< 0.05
Isometric exercise training of the legs, but not arms, improves orthostatic tolerance, suggesting limb-specific adaptations independent of resting blood pressure reductions.

Leg isometric training was associated with improved orthostatic tolerance; leaves open limb-specific effects independent of BP reduction pending randomized confirmation.
Howden et al. (2002) reported an RCT. Isometric exercise training vs. Normal daily activities was evaluated on Resting systolic blood pressure (p=< 0.05). Isometric exercise training of the legs and arms significantly reduced resting systolic blood pressure compared to controls (P<0.05), but orthostatic tolerance only increased after leg-training.
