Evaluation of The Acute Hormonal Responses To Concentric, Eccentric And Concentric_ Eccentric Muscle Actions in Healthy Young Men Introduction: Resistance exercise is a potent stimulus for acute increase in the concentrations of circulating hormones such as Growth Hormone (GH) and Testosterone. Conventional resistance exercise is performed using sequential concentric (CON) and eccentric (EC...

The potential of physical exercise to decrease body weight, alleviate depression, combat aging and enhance cognition has been well-supported by research studies. However, exercise regimens vary widely across experiments, raising the question of whether there is an optimal form, intensity and duration of exertion that would produce maximal benefits. In particular, a comparison of forced and volu...

Microgravity adversely affects several physiological systems. As space exploration moves to extended flights, understanding which mechanisms microgravity influences may contribute to the health and safety of astronauts aboard. Maximum oxygen consumption (VO2 max) testing is used to monitor changes to cardiorespiratory function. Currently the equipment used to such testing aboard the Internation...

for normally hydrated individuals. However, when working in stressful environments for extended durations, particularly when wearing personal protective equipment, fluid losses via sweat secretion are dramatically elevated, and can approach 8-16 L.day -1 . Indeed, during a moderate exercise-heat stress, whole-body sweat rates typically range between 1-1.5 L.h -1 , and fluid loss at this rate si...

OBJECTIVE To determine the acute effects of pyridostigmine bromide, a reversible cholinesterase inhibitor, during exercise in patients with coronary artery disease. DESIGN Double blind, randomised, placebo controlled, crossover study. SETTING Outpatients evaluated in an exercise test laboratory. PATIENTS 15 patients with exercise induced myocardial ischaemia. INTERVENTIONS Maximal cardi...

PURPOSE It is now established that unaccustomed eccentric exercise leads to muscle fiber damage and to delayed-onset muscle soreness (DOMS) in the days after exercise. However, a second bout of eccentric exercise, a week after the first, produces much less damage and soreness. The purpose of this study was to provide evidence from muscle mechanical properties of a proposed mechanism for this tr...

Abstract Background Power assisted exercise is accessible and acceptable for people with stroke. The potential technological advancement of the equipment to improve user experience has been identified. Involvement end users service providers in design health technologies essential determining how said technology perceived adopted. This project invited stroke influence features determine machine...

The variable natural history of sarcoidosis and the toxicity of corticosteroids result in many clinical situations where there is controversy concerning the need for treatment. Progressive incremental testing is an excellent method to identify physiologic mechanisms responsible for exercise limitation. It is therefore ideal to determine if subjective symptoms such as dyspnea are due to cardiac ...

The present study was conducted to investigate the effect of daily passive exercise using a horseback riding machine (Joba) on insulin sensitivity and resting metabolism in middle-aged, diabetic patients. Participants were 24 type 2 diabetes mellitus patients aged 59 +/- 8 years (mean +/- SD; range from 43 to 75 years of age). Patients were randomly divided into control (normal lifestyle) and J...
