The effect of a tryptophan-depleted diet on voluntary exercise in mice
… and is found in elevated levels following exercise. A quantitative deficit in serotonin or abnormality in its mode of action is thought to be one cause behind several psychological disorders such as depression, eating disorders, and obsessive-compulsive disorder. A decrease in dietary …

Voluntary Exercise and Neurotrophin Signaling Affect the Development and Presentation of Painful Neuropathy
… nature. However, recent research suggests that exercise may be beneficial in reducing PDN. The purpose of this work was to test the effects of obesity and a high-fat diet on the development of DN, to investigate how diabetes alters neurotrophins and to determine if voluntary exercise is capable …

The effect of voluntary exercise on adult hippocampal neurogenesis in maternally separated rats
… in neurogenesis may be a key-mediating factor. Voluntary wheel running is a form of exercise that increases neurogenesis and decreases depression-like behaviour in rats. However, the exact molecular role of neurogenesis in exercise-induced antidepressant effects still remains unanswered. This …

The effects of N-acetylcysteine infusion on performance, glutathione and ion regulation during voluntary exercise in humans
… have investigated NAC infusion effects during voluntary exercise in humans. This thesis investigated whether an NAC infusion protocol that was modified to minimise these adverse reactions, would augment time to fatigue, enhance glutathione availability and enhance potassium (K+) regulation …

EGCG and voluntary exercise : an examination of treatment effects using the TgCRND8 mouse model of Alzheimer's disease
… model of Alzheimer's disease has shown that voluntary exercise implemented for long time periods (5-months) and starting at very young ages (1-month), prior to the development of disease pathology, reduces cognitive impairments; however, approximately 1-month of exercise started at 80-days …

Voluntary exercise in the C57B1/6J mouse: phenotypic effects of varying dietary fat levels and hippocampal gene expression differences between high-level and low-level exercisers
The drive to exercise voluntarily likely results from complex interactions between genes in many organ systems and various psychological parameters, such as motivation and the perception of fatigue. Reproducible variations in exercise intensity and duration are well established in laboratory …

Exercise induced neuroprotection in spontaneuosly running rats
We investigated the effects of voluntary exercise on neuroprotection after unilateral lesions with 6-hydroxydopamine. Rats were divided into runners (had access to running wheel) and non-runners (their running wheels were immobilised). Two weeks after injection of the neurotoxin, the rats were …

The Effects Of Exercise On Capillary Supply To The 'transition Zone' Of Infarcted Rat Hearts
… from the literature indicates that exercise can stimulate capillary growth in skeletal muscle and healthy myocardium. My second objective was to determine whether voluntary exercise (running) also promotes revascularization in the transition zone.;One week following LCA occlusion, …

Myogenin Modulates Exercise Endurance By Altering Skeletal Muscle Metabolism
… Myog-deleted mice demonstrated enhanced exercise endurance during involuntary treadmill running. Altered blood glucose and lactate levels in sedentary Myog-deleted mice after exhaustion suggest an enhanced glycolytic metabolism and an ability to excessively deplete muscle and liver …

Death, survival, and morphological development of hippocampal granule cells born in an inflammatory environment
… formation. A variety of stimuli such as voluntary exercise, epileptic seizure activity and inflammation can affect the basal level of neurogenesis. In the course of pathological conditions such as Alzheimer’s disease, multiple sclerosis, epilepsy and stroke, an inflammatory response is …

Non-motor symptoms in the aav-α-synuclein rat model of Parkinson’s disease: exercise as a therapeutic intervention
… Furthermore, it set out to explore whether voluntary exercise could ameliorate motor and NMS in this PD model, including if exercise could protect against hippocampal-associated cognitive deficits by modulating adult hippocampal neurogenesis. We demonstrated that unilateral and bilateral …

The effect of exercise on spatial learning and hippocampal proteins in maternally separated adult rats
… linked to poor cognitive function. In contrast, exercise enhances cognitive function. Previously, we reported that MS improved object location memory. However, exercise had no effect on object location memory despite increases in levels of synaptophysin and phospho-extracellular signal-regulated …

Neuromuscular electrical stimulation to improve muscle weakness in hip osteoarthritis: A feasibility study
… restore and increase skeletal muscle mass when voluntary exercise is limited due to pain during joint loading. The scoping review conducted in this integrated thesis identified i) a paucity of research exploring NMES interventions in individuals with hip osteoarthritis and ii) emerging evidence …

Impact of an Acute Bout of Low- and High-Frequency Neuromuscular Electrical Stimulation on Voluntary Muscle Fatigue and Antioxidant Response
… particularly in populations with limited voluntary exercise capacity. Stimulation frequency is a key NMES parameter that may influence force production, fatigue development, and biological markers involved in skeletal muscle health, muscle growth and general physical health. PURPOSE: The …

Fatigue-Independent Alterations in Muscle Activation and Effort Perception During Forearm Exercise: The Role of Local Oxygen Delivery
In exercise, the sensations of effort to make the muscles do exercise can contribute to an individual’s decision to stop exercise or decrease exercise intensity. Skeletal muscle fatigue is one mechanism by which the effort required to continue exercise can be increased. In order to continue …

Effects of exercise on age- and stress- related attenuation of vaccination responses in mice
… published studies suggest that acute eccentric exercise and exercise training can improve vaccination responses in humans. Normal aging and chronic stress can lead to immunosenescence and immunosuppression, respectively, and there may be a role for exercise in augmenting immune responses under …
