Conventional duplex ultrasound is commonly used to measure blood velocity in the internal carotid artery (ICA) for disease screening and cerebral or extracranial flow estimation. Pouseillian-based flow calculations assume laminar flow, whic...
Local ischemic preconditioning improves skeletal muscle blood flow and vasodilation during exercise in older adults [0.03%]
局部缺血预处理可改善老年人运动时骨骼肌的血液流动和血管舒张状况

To run faster, distance runners need shoes that reduce their metabolic energy expenditure. Here, we studied how shoe heel-toe drop affects metabolic energy expenditure during running. To do so, we studied 20 runners as they ran at 3.5 m/s i...
