Exercise training as a component of pulmonary rehabilitation improves health-related quality of life (HRQL) and exercise capacity in people with chronic obstructive pulmonary disease (COPD). However, some individuals may have difficulty performing exercise at an adequate intensity. Non-invasive ventilation (NIV) during exercise improves exercise capacity and dyspnoea during a single ...

The effects of different types of acute bouts of resistance exercise on autonomic modulation in individuals that are resistance-trained compared to untrained individuals are unknown. Seventeen untrained and 17 resistance-trained participants were assessed for autonomic modulation after various acute resistance exercise bouts. Electrocardiogram readings were collected at rest and 25 min ...

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 ...

Humans are increasingly approaching an era where cardiovascular health seems to be one of the major upper limits on achievable lifespan. An increasing body of scientific research and observational evidence indicates that resting heart rate (HR) is inversely related to the lifespan among homeothermic mammals and within individual species. Heart ...

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 ...

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 ...

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 ...

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 ...

It is generally believed that optimal hypertrophic and strength gains are induced through moderate- or high-intensity resistance training, equivalent to at least 60 % of an individual's 1-repetition maximum (1RM). However, recent evidence suggests that similar adaptations are facilitated when low-intensity resistance exercise (~20-50 % 1RM) is combined with blood flow restriction ...

This study aimed to clarify the characteristics of muscle activities during push-up exercises performed under sling condition by comparison with those performed underground condition. We hypothesized that sling-based push-ups induce higher muscle activities than the ground-based push-ups, and its effects are more prominent in dynamic compared to static exercise owing ...

During the stress response to intense exercise, the sympathetic nervous system (SNS) induces rapid catabolism of energy reserves through the release of catecholamines and subsequent activation of protein kinase A (PKA). Paradoxically, chronic administration of sympathomimetic drugs (β-agonists) leads to anabolic adaptations in skeletal muscle, suggesting that sympathetic outflow also ...

Hypoxic exercise is characterized by workloads decrements. Because exercise and high altitude independently elicit redox perturbations, the study purpose was to examine hypoxic and normoxic steady-state exercise on blood oxidative stress. Active males (n=11) completed graded cycle ergometry in normoxic (975m) and hypoxic (3000m) simulated environments prior to programing subsequent ...

Background: Alpha-adrenergic-mediated vasoconstriction is greater during simulated exercise in animal models of metabolic syndrome (MetSyn) when compared with control animals. In attempt to translate such findings to humans, we hypothesized adults with MetSyn (n=14, 35±3 years) would exhibit greater α-adrenergic responsiveness during exercise when compared with age-matched healthy controls (n=16, ...

Enhanced sympathetic activity at the ventricular myocardium can destabilize repolarization, increasing the risk of death. Sympathetic activity is known to cluster in low-frequency bursts; therefore, we hypothesized that sympathetic activity induces periodic low-frequency changes of repolarization. We developed a technique to assess the sympathetic effect on repolarization and identified periodic ...

Based on reports of exaggerated blood pressure responses to whole-body exercise in patients with metabolic syndrome (MetSyn), we tested the hypothesis that MetSyn adults would exhibit augmented sympathetic and pressor responses to mechanoreflex and metaboreflex activation when compared with healthy, age-matched control subjects. We studied 12 adults with MetSyn (34±3years) ...

Resistance exercise (RE) may lead to a post-exercise hypotension (PEH) response. Previous studies showed that green tea (GT) and its polyphenols, especially Epigallocatechin-3-gallate (EGCG) may have a favorable effect on blood pressure (BP). We investigated the green tea extract (GTE) effects on BP, heart rate (HR), and rate pressure product ...
