Hypertension during Weight Lifting Reduces Flow-Mediated Dilation in Nonathletes
EXERCISE ENDOTHELIUM VASODILATION BRACHIAL ARTERY
2018/4/24
Purpose The purpose of this study was to determine whether increased intraluminal pressure is the damaging factor that reduces flow-mediated dilation (FMD) in young, healthy subjects after resistance ...
Thermodilution-determined Internal Jugular Venous Flow
CEREBRAL BLOOD FLOW INTERNAL JUGULAR VENOUS FLOW THERMODILUTION TRANSCRANIAL DOPPLER
2018/4/24
Purpose Cerebral blood flow (CBF) increases ~20% during whole body exercise although a Kety–Schmidt–determined CBF is reported to remain stable; a discrepancy that could reflect evaluation of arterial...
Blood Flow during Handgrip Exercise in COPD: Effect of Vitamin C
ANTIOXIDANTS NITRIC OXIDE ENDOTHELIUM BRACHIAL ARTERY
2017/4/13
Purpose: Chronic obstructive pulmonary disease (COPD) is associated with vascular dysfunction, possibly related to increased oxidative stress. Exercise hyperemia may similarly be impaired, which could...
Visual flow and direction of locomotion.
Wayfinding on foot from information in retinal,not optical flow
Wayfinding information retinal optical flow
2015/8/13
People find their way through cluttered environments with ease and without injury. How do they do it? Two approaches to wayfmding are considered: Differential motion parallax (DMP) is a retinal motion...
Heading and path information from retinal flow in naturalistic environments
Heading path information retinal flow naturalistic environments
2015/8/13
In four experiments, we explored the heading and path information available to observers as we sim-ulated their locomotion through a cluttered environment while they fixated an object off to the side....
Metabolic and cardiovascular responses to upright cycle exercise with leg blood flow reduction
Aerobic exercise doppler echocardiography
2015/5/5
The purpose of this study was to examine the metabolic and
cardiovascular response to exercise without (CON) or with
(BFR) restricted blood flow to the muscles. Ten young men
performed upright c...
Acute Inactivity Impairs Glycemic Control but Not Blood Flow to Glucose Ingestion
INACTIVITY BLOOD GLUCOSE INSULIN CONDUIT ARTERY FLOW
2017/4/19
Purpose: Insulin-stimulated increases in skeletal muscle blood flow play a role in glucose disposal. Indeed, 7 d of aerobic exercise in patients with Type 2 diabetes increased blood flow responses to ...
Effect of Blood Flow Restriction on Tissue Oxygenation during Knee Extension
RESISTANCE TRAINING EXERCISE BLOOD FLOW RESTRICTION FATIGUE DIFFUSE OPTICS TISSUE OXYGENATION
2017/4/14
Purpose: Time-resolved near-infrared spectroscopy was used to quantify tissue oxy- and deoxyhemoglobin concentrations ([HbO2] and [HbR]) and O2 saturation (stO2) in the oblique fibers of the vastus me...
Flow-Mediated Dilation in Athletes: Influence of Aging
FLOW-MEDIATED,DILATION EXERCISE AGING META-ANALYSIS
2017/5/24
Controversy exists on whether endothelial function is enhanced in athletes. We sought to systematically review the literature and determine whether endothelial function, as assessed by flow-mediated d...
Exercise Training Augments Regional Bone and Marrow Blood Flow during Exercise
SKELETAL,BLOOD FLOW VASCULAR,RESISTANCE BONE,HEMODYNAMICS MICROCIRCULATION
2017/5/24
The principal nutrient artery to the femur demonstrates an increase in nitric oxide–mediated vasodilation in rats after treadmill exercise training. The present study sought to determine whether exerc...
Optic Flow Influences Perceived Exertion and Distance Estimation but not Running Pace
RUNNING EFFORT SENSATION VISION RPE
2017/5/24
This study aimed to examine the effect of variations in optic flow on perceived and actual running pace and RPE.
V˙O2peak, Myocardial Hypertrophy, and Myocardial Blood Flow in Endurance-Trained Men
HEART PERFUSION ENDURANCE,TRAINING POSITRON,EMISSION,TOMOGRAPHY
2017/5/23
Endurance training induces cardiovascular and metabolic adaptations, leading to enhanced endurance capacity and exercise performance. Previous human studies have shown contradictory results in functio...
Dynamic Heterogeneity of Exercising Muscle Blood Flow and O2 Utilization
EXERCISE PERFORMANCE V˙O2 KINETICS MUSCLE FIBER TYPES VO2TRANSPORT HEALTH AND DISEASE
2017/5/19
Resolving the bases for different physiological functioning or exercise performance within a population is dependent on our understanding of control mechanisms. For example, when most young healthy in...
