Superficial femoral artery (SFA) blood flow response, shown as the 1-s averages of the beat-by-beat means of one subject, to the exercise protocol with the time points selected for analysis indicated. Responses to the exercise protocol were determined by comparing a mean of the 60 s before exercise (Rest) with means of the initial 10 s of exercise (St Ex), the last 60 s of exercise (Ex), the first 10 s following exercise (Post Ex), and the last 30 s of the 2-min recovery period (Rec). Additional 10-s means were determined after 2 min of recovery, when the recovery compressions were stopped (Post Rec), for the no applied compression (NoComp) and compression during 2 min of standing postexercise recovery (RecComp) conditions only.
