During supine passive heating, increases in skin blood flow (SkBF) and cardiac output (Qc) are both blunted in older adults. The aim here was to determine the effect of acutely correcting the peripheral vasodilatory capacity of aged skin on the integrated cardiovascular responses to passive heating. A secondary aim was to examine the SkBF-Qc relation during hyperthermia in the presence (upright...

BACKGROUND Passive mobilization of shoulder region joints, often in conjunction with other treatment modalities, is used for the treatment of people with shoulder pain and minimal movement restriction. However, there is only limited evidence supporting the efficacy of this treatment modality. OBJECTIVE The purpose of this study was to determine whether passive mobilization of shoulder region ...

PURPOSE Previous studies have shown that physical activity improves learning and memory. Present study was performed to determine the effects of short term and long term treadmill exercise on learning, memory consolidation and retrieval of passive avoidance learning in an animal model. METHODS In this study fifty male Wistar rats with 3-4 months of age were randomly divided into five groups (...

A clinical trial assessed the effect of passive exercise of the lower limb during surgery on the incidence of early postoperative deep vein thrombosis. Thrombosis was diagnosed by means of the (125)I-fibrinogen uptake test. Passive exercise of the lower limb during the operation was achieved by using a motorized foot mover designed for use on supine subjects, and by pedalling only one leg each ...

Background: A sequence of time-dependent changes can affect the brainchr('39')s functional capacity. Aims: This study aimed at investigating the effects of forced aerobic exercise (FAE) versus the rosemary extract (RE) on the learning abilities and oxidative stress modulation in rats. Methods: Young and old rats received daily FAE and RE for 3 months. Using the passive avoidance (PA) test, we...

The concept that exercise limitation in patients with chronic heart failure (HF) is due to elevated filling pressures or inadequate cardiac output has been largely abandoned and replaced by a new paradigm. “The Muscle Hypothesis of HF,” originated by Drs. Coats and Piepoli, hypothesizes that abnormalities of skeletal muscle, including the sensory nerve fibers that mediate reflex changes in the ...

OBJECTIVES The aim of this study was to determine the contribution of pre-load and heart rate to pump flow in patients implanted with continuous-flow left ventricular assist devices (cfLVADs). BACKGROUND Although it is known that cfLVAD pump flow increases with exercise, it is unclear if this increment is driven by increased heart rate, augmented intrinsic ventricular contraction, or enhanced...

CONTEXT With regard to intermittent training exercise, the effects of the mode of recovery on subsequent performance are equivocal. OBJECTIVE To compare the effects of 3 types of recovery intervention on peak torque (PT) and electromyographic (EMG) activity of the knee extensor muscles after fatiguing isokinetic intermittent concentric exercise. DESIGN Crossover study. SETTING Research la...

The purpose of the study was to examine the effect of 1) active (loadless pedaling), 2) passive (assisted pedaling), and 3) inactive (motionless) recovery modes on mean arterial pressure (MAP), cutaneous vascular conductance (CVC), and sweat rate during recovery after 15 min of dynamic exercise in women. It was hypothesized that an active recovery mode would be most effective in attenuating the...
