Key result
Low-intensity single-leg exercise reduces femoral-to-ankle pulse wave velocity by ~8% versus the unexercised leg.
Why the study?
Does low-intensity single-leg exercise reduce regional arterial stiffness in young men?
Does low-intensity single-leg exercise reduce regional arterial stiffness in young men?
Low-intensity single-leg exercise acutely decreases regional arterial stiffness in the exercised limb, suggesting local exercise-related factors mediate this effect.

May indicate local mediation of acute vascular effects in young men; hypothesis-generating and should not yet change practice.
We examined the effect of low-intensity single-leg exercise (20 or 30 watt, 5 min) on pulse wave velocity from the femoral to the ankle arteries in 18 young men. After the exercise, the velocity significantly decreased in the exercised leg, but not in the counterpart, suggesting that the decrease in arterial stiffness in the exercised leg was induced mainly by exercise-related regional factors.

Sugawara et al. (2003) studied Healthy (n=18). Low-intensity single-leg exercise vs. Non-exercised leg was evaluated on Pulse wave velocity from the femoral to the ankle arteries (f-a PWV) (p=<0.05). Low-intensity single-leg exercise significantly decreased femoral-to-ankle pulse wave velocity in the exercised leg (from 9.1 to 8.4 m/s) but not in the non-exercised leg.
