This study tested the hypothesis that during fatiguing quadriceps exercise, supraspinal fatigue develops late, is associated with both increased corticospinal excitability and inhibition and recovers quickly. Eight subjects performed 20-s contractions (15 s at 50% maximal voluntary contraction (MVC) followed by 5-s MVC) separated by a 10-s rest period until ...

Repeated administration of methamphetamine (mAMPH) to rodents in a single-day "binge" dosing regimen produces long-lasting damage to forebrain dopaminergic nerve terminals as measured by decreases in tissue dopamine (DA) content and levels of the plasmalemmal DA transporter (DAT). However, the midbrain cell bodies from which the DA terminals arise survive, ...

The goal of the study was to determine whether the label given to an exercise bout affects immediate post-exercise food intake. The authors hypothesized that explicitly labeling an exercise bout 'fat-burning' (vs. labeling an exercise bout 'endurance' exercise) would increase post-exercise food intake in individuals who self-impose physical activity, because ...

Physiological responses to hypoxia vary between individuals and genetic factors are conceivably involved. Using a monozygotic twin design, we investigated the role of genetic factors in physiological responses to acute hypoxia. Thirteen pairs of monozygotic twin brothers participated in two experimental sessions in a normobaric hypoxic facility with a 2-week ...

The metabolic syndrome (MetS) is associated with a three-fold increase risk of cardiovascular (CV) morbidity and mortality, which is in part, due to a blunted CV reserve capacity, reflected by a reduced peak exercise left ventricular contractility and aerobic capacity, and a blunted peak arterial-ventricular coupling. To date, no study ...

Many studies have failed to show that pre-sleep exercise has a negative effect on sleep onset. However, since only a moderate level of physiological excitement was observed at bedtime in these studies, it remains unclear whether a larger magnitude of physiologic excitement present at bedtime would disrupt sleep onset. This ...

Adverse cardiovascular events are more prevalent during winter and in people that exercise/work in cold temperatures. Since pulse wave analysis indices, aortic systolic blood pressure (ASBP), augmentation index (AIx), and wasted left ventricular pressure energy (ΔE w), are stronger predictors of cardiovascular events and myocardial performance than brachial blood pressure ...

Pulmonary diffusion (DLCO) increases during exercise due to greater pulmonary capillary volume (Vc) and membrane diffusing capacity (DM). However, after heavy exercise there is a reduction in resting DLCO. It is unclear whether this post-exercise effect will attenuate the normal increase in DLCO, Vc and DM during subsequent exercise and ...

Exercise testing for cardiac disease in children differs in many aspects from the tests performed in adults; their cardiovascular response to exercise presents different characteristics, which are essential for the interpretation of hemodynamic data. Moreover, diseases that are associated with myocardial ischemia are very rare in young patients, and the ...

Compensatory exercise (exercise performed in an effort to control weight/shape or in response to caloric intake) and thinness expectancies (beliefs that thinness will improve the overall quality of life) are strongly linked to the development, maintenance, severity, and outcome of eating disorders. There is little literature, however, examining the relationship ...

Cardiac ischemia and angina pectoris are commonly experienced during exertion in a cold environment. In the current study we tested the hypotheses that oropharyngeal afferent blockade (i.e., local anesthesia of the upper airway with lidocaine) as well as systemic beta-adrenergic receptor blockade (i.e., intravenous propranolol) would improve the balance between ...

Physical activity is a potent therapy for both the prevention and treatment of cardiovascular disease. Exercise appears to most benefit people who are the least active. There is some evidence to suggest that a curvilinear relationship exists between exercise and survival, whereby beyond an optimal level of fitness, the principle ...

The β2-adrenergic system is an important regulator of human adipose tissue lipolysis. Polymorphisms that result in amino acid substitutions in the β2-adrenergic receptor have been reported to alter lipolysis. We hypothesized that variations in the amino acid at position 16 of the β2-adrenergic receptor would result in different lipolytic responses ...

Hypertension is a major health concern, and current recommendations for blood pressure management (lifestyle modifications and pharmacological intervention) have not been universally successful. For two decades, isometric exercise training (IET) has become established as effective at reducing in resting BP (RBP) in a short period (4-10 weeks). The most common ...

The accepted model of autonomic control of heart rate (HR) during dynamic exercise indicates that the initial increase is due entirely to withdrawal of parasympathetic nervous system activity (PSNA) and that subsequent increases in HR are entirely due to increases in cardiac sympathetic activity. In the present review we sought ...

To better understand the hemodynamic and autonomic reflex abnormalities in heart-failure patients (HF), we investigated the influence of group III/IV muscle afferents on their cardiovascular response to rhythmic exercise. Nine HF-patients (NYHA class-II, mean left ventricular ejection-fraction: 27±3%) performed single leg knee-extensor exercise (25/50/80% peak-workload) under control conditions and with ...

Exercise increases core body temperature (Tc), which is necessary to optimise physiological processes. However, excessive increase in Tc may impair performance and places participants at risk for the development of heat-related illnesses. Cooling is an effective strategy to attenuate the increase in Tc. This meta-analysis compares the effects of cooling ...
