Summary Background and aim:  Limb femoral arterial blood flow (LBF) is known to increase linearly with increasing workload under steady‐state conditions, suggesting a close link between LBF and metabolic activity. We, however, hypothesized that sudden physiological and spontaneous changes in exercis...
