INTRODUCTION: Resistance training has been well established as an effective treatment strategy to increase skeletal muscle mass and strength in the elderly. We assessed whether dietary protein supplementation can further augment the adaptive response to prolonged resistance type exercise training in healthy, elderly men and women. METHODS: Healthy, elderly men ...

We examined the relationship between implicit and explicit "exerciser" and "sedentary" self-identity when activated by stereotypes. Undergraduate participants (N = 141) wrote essays about university students who either liked to exercise or engage in sedentary activities. This was followed by an implicit identity task and an explicit measure of exercise ...

Exercise-induced heat stroke is defined as core temperature greater than 104 degrees F (400 degrees C) accompanied by signs or symptoms of organ system failure, most commonly CNS dysfunction. Exertional heatstroke is a life-threatening emergency that requires immediate whole-body cooling for a satisfactory outcome. Cooling should be initiated and, in ...

PURPOSE: Hyperventilation increases the clearance of carbon monoxide (CO) from blood, thus we hypothesised that CO elimination would be enhanced with exercise. Accordingly, this study examined the effect of exercise on the half-life of carboxyhemolobin elimination. METHODS: Six healthy subjects (3 males and 3 females) with mean (SD) ages of ...

Abstract Self-presentational concerns, shown to influence exercise-related cognitions and behaviours, are evaluated frequently in the absence of exercise or following a single bout of physical activity. The purpose of the present study was to examine longitudinally, the extent to which participating in a structured 12-week cardiovascular exercise intervention elicited changes ...

The time spent in sedentary behaviors has been shown to be independent of exercise in epidemiological studies. We examined within an individual whether exercise alters the time of muscular inactivity within his/her normal daily life. Quadriceps and hamstring muscle electromyographic activities and heart rate were measured during 1 to 6 ...

Cytokines (IL-6, IL-10, and TNF-α) are increased after exhaustive exercise in the retroperitoneal adipose tissue (RPAT) and mesenteric adipose tissue (MEAT). An exhaustive acute exercise protocol induces inflammation in adipose tissue that lasts 6 h after the exercise has ended. It is well-established that this protocol increases circulating plasma levels of ...

Exercise can be used to enhance neuroplasticity and facilitate motor recovery after a stroke in rats. We investigated whether treadmill running could reduce brain damage and enhance the expression of midkine (MK) and nerve growth factor (NGF), increase angiogenesis and decrease the expression of caspase-3. Seventy-seven Wistar rats were split ...

Many thermal physiologists follow the conventional wisdom that physiological heat adaptations occur in the summer for people living in a humid continental climate (e.g. Central Canada, North-eastern and Mid-western United States and Eastern Europe); therefore experimentation across seasons is often avoided. However, since modern behavioral adaptations, such as air conditioning, ...

Previous studies indicate that physical exercise improves contextual fear memory, as evidenced by increased freezing behavior when rats are returned to a training environment that was initially paired with footshock. However, freezing behavior could also be affected by fatigue, especially because rats were tested shortly after the end of the ...

Previous studies have shown that exercise training reduced white adipose tissue (WAT) mass compared to that in sedentary controls, and that the smaller mass contained fewer adipocytes. However, the effect of exercise training on adipogenesis is not completely clear. Therefore, we re-examined the effect of exercise training on adipocyte numbers ...

Research has shown that physical exercise may reduce degeneration in certain brain regions experiencing ataxia. Our laboratory utilized mutant spastic Han-Wistar rats (sHW) that display developmental abnormalities, including spastic paresis, fore limb tremors, hind limb rigidity, and a reduced life span (60-65 days of age). Concomitant neurodegeneration has been observed ...

Ghrelin and exercise have been known to stimulate the release of growth hormone which is related to the glucose metabolism. However, the age effects of exercise on ghrelin in energy consumption remain unclear. Young (3 month old) and middle-aged (12 month old) Sprague-Dawley male rats were overnight fasted, and then randomly partitioned ...

Impairment of renal dopamine D1 receptor (D1R)-mediated natriuresis is associated with hypertension in humans and animal models, including obese Zucker rats. We have previously reported that treatment of these rats with antioxidants or insulin sensitizers reduced insulin levels and oxidative stress, restored D1R-mediated natriuresis, and reduced blood pressure. Furthermore, the ...

Physical activity has a modulatory role on regulatory steps of excitation-contraction coupling (ECC) determining skeletal muscle contractility. We evaluated and compared the contractile responsiveness and caffeine-induced contractures of fast (extensor digitorum longus; EDL) and slow-twitch (soleus; SOL) muscles in suspension hypokinesia (SH) and exercised rats. After SH or low intensity ...

Exercise has recently been suggested as an attractive alternative to pharmacotherapy for treating drug addiction. The goal of this study was to determine, using an animal model, whether aerobic exercise may block reinstatement of cocaine-seeking and its underlying neurobiology (i.e., neuronal signaling in the prefrontal cortex). Following acquisition and 10 ...

We hypothesized that the reduction in liver fat accumulation known to occur with exercise training in ovariectomized (Ovx) rats is associated with reduced expression of genes involved in lipogenesis while favoring the expression of transcription factors regulating lipid oxidation. We also tested the hypothesis that liver fat accumulation in Ovx ...
