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 (n=...

the pathophysiology of primary benign exertional headache (eh) is not still clearly defined. some researchers have suggested an impaired vascular response as the etiology of this disorder. in this study we investigated whether there are any differences in blood pressure (bp) and heart rate (hr) of the subjects in course of the static and dynamic exercises and the treadmill stress test between t...

A series of four papers in JEB in 1982, masterminded by C. Richard Taylor, asked two deceptively simple questions: why does running faster consume metabolic energy at a faster rate, and why do larger animals require less energy to transport each gram of tissue? The audacious goal of these experiments was to link the energetics and biomechanics of terrestrial locomotion. These were not the first...

Huntington's disease (HD) is an inherited genetic disorder, characterized by cognitive dysfunction and abnormal body movements called chorea. Quinolinic acid (QA) is an endogenous metabolite of tryptophan in the kynurenine pathway. QA-induced alterations are similar to the symptoms of HD patients. Physical exercise has beneficial effects on the brain functions. Exercise increases production of ...

OBJECTIVE To determine if the metabolic cost of the incremental shuttle-walking test protocol is the same as treadmill walking or predicted values of walking-speed equations. SETTING Primary care (community-based cardiac rehabilitation). PARTICIPANTS Eight Caucasian cardiac rehabilitation patients (7 males) with a mean age of 67±5.2 years. PRIMARY AND SECONDARY OUTCOME MEASURES Oxygen con...

This study investigated the effect of both walking speed and external ankle load on the kinetic patterns of treadmill walking in preadolescents with and without Down syndrome (DS). Ten preadolescents with DS and ten age- and gender-matched children with typical development (TD) participated in this study. We manipulated two treadmill speeds and two external ankle loads. Treadmill speeds were eq...

We hypothesized that all-out running speeds for efforts lasting from a few seconds to several minutes could be accurately predicted from two measurements: the maximum respective speeds supported by the anaerobic and aerobic powers of the runner. To evaluate our hypothesis, we recruited seven competitive runners of different event specialties and tested them during treadmill and overground runni...

OBJECTIVE To evaluate the ability of different parameters of exercise treadmill test to detect autonomic dysfunction in hemodialysis patients. METHODS Cross-sectional study involving hemodialysis patients and a control group. Clinical examination, blood sampling, echocardiogram, 24-hour Holter, and exercise treadmill test were performed. A ramp treadmill protocol symptom-limited with active r...

Freezing is a disabling symptom in patients with Parkinson's disease. We investigated the effectiveness of a new rehabilitation strategy based on treadmill training associated with auditory and visual cues. Forty Parkinsonian patients with freezing were randomly assigned to two groups: Group 1 underwent a rehabilitation program based on treadmill training associated with auditory and visual cue...

Cyclooxygenase-2 (COX-2) is believed to be a multifunctional neural modulator that affects synaptic plasticity in the hippocampus. In the present study, we investigated the differential effects of treadmill exercise on COX-2 immunoreactivity in the dentate gyrus in early and chronic diabetic stages in Zucker diabetic fatty (ZDF) rats and lean control (ZLC) rats. To this end, ZLC and ZDF rats at...
