This study investigated the effect of different exercise bouts on plasma leptin response. Trained men (n = 9) performed a short duration, maximal intensity (MAX) bout and a 60-min endurance run at approximately 70% of maximal oxygen consumption (END). Blood was collected before, immediately after, 24 h after (24 h Post), and 48 h after exercise (48 h Post)(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)
The purpose of this study was to examine the relation of leptin to metabolic and dietary factors in college-age adults. Young adult women and men (n = 32) were recruited and underwent testing for measurement of body mass index, body composition, peak oxygen consumption (VO2peak), dietary intake, and plasma levels of leptin and insulin. Ln leptin was(More)
PURPOSE Our purpose was to determine whether spinal cord injured (SCI) subjects have decreased femoral artery diameter and maximal hyperemic blood flow when expressed per unit of muscle volume compared with able-bodied (AB) individuals. A secondary purpose was to determine whether blood flow recovery rates were similar between groups. METHODS Blood flow(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. Methods: Thirty-seven healthy elderly men(More)
STUDY DESIGN Cross sectional comparison, control group. OBJECTIVE To determine if incomplete spinal cord injured patients (SCI) have an abnormal blood flow response to cuff ischemia compared to able-bodied individuals (AB). SETTING Academic institution. METHODS Blood flow in five chronic incomplete SCI patients (C4-C5) and 17 able bodied individuals(More)
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)
OBJECTIVE To compare the effects of commercially sold menthol (3.5%) ointment and cold application on blood flow in the forearm. DESIGN : Prospective counterbalanced design. SETTING University research laboratory. PARTICIPANTS Twelve (6 men and 6 women) college-aged students. INTERVENTIONS Each participant had blood flow measured in the brachial(More)
This paper examined the role of metabolites in causing muscle fatigue. Previous studies have shown that Pi (H2PO4-, HPO4-2) and H+ may be important factors in causing fatigue. A key question is the potential interaction between metabolic end-products and calcium related excitation-contraction coupling fatigue (ECC). An in vivo rat muscle model was used to(More)
STUDY DESIGN Cross-sectional comparison, control group. OBJECTIVES To investigate the relationship between carotid arterial stiffness and circulating markers for cardiovascular disease (CVD) in spinal cord-injured (SCI) subjects compared with able-bodied (AB) individuals. SETTING University Research Laboratory, University of Louisville. METHODS SCI(More)
