Our purpose was to measure blood flow and muscle fatigue in chronic, complete, spinal cord-injured (SCI) and able-bodied (AB) individuals during electrical stimulation. Electrical stimulation of the quadriceps muscles was used to elicit similar activated muscle mass. Blood flow was measured in the femoral artery by Doppler ultrasound. Muscle fatigue was… (More)
BACKGROUND Our purpose was to determine if aging had an influence on muscle blood flow independent of habitual physical activity levels. METHODS Blood flow was measured in the femoral artery by Doppler ultrasound after cuff occlusion of 10 minutes. Active and inactive older subjects (73 +/- 7 years) were compared to active and inactive young subjects (26… (More)
Background: The purpose of this study was to measure blood flow in the carotid and femoral arteries, heart rate and blood pressure in response to postural challenge in older adults. A second purpose was to determine if older men and women have different cardiovascular responses to a postural challenge such as tilt.
Correction After publication of our paper , we discovered that our normalized blood velocity and compliance numbers were 60 times higher than they should have been. The revised Figure 1 and Figure 2, along with Table 1 are shown here with the correct values. Heart rate, blood pressure, and half time to recovery of blood flow and oxygen saturation from… (More)
Int J Exerc Sci 1(4) : 163-176, 2008. The consumption of a high-fat meal induces transient vascular dysfunction. Aerobic exercise enhances vascular function in healthy individuals. Our purpose was to determine if different levels of aerobic capacity impact vascular function, as measured by flow mediated dilation, following a high-fat meal. Flow mediated… (More)
