BACKGROUND This study examined the effects of inhaled furosemide on the ventilatory and perceptual response to high-intensity constant-load cycle exercise in chronic obstructive pulmonary disease (COPD). METHODS In a randomised, double-blind, placebo-controlled, crossover study, 20 patients with COPD (mean (SD) forced expiratory volume in 1 s 45 (15)% predicted) received either nebulised furo...
To test the hypotheses that short-term bed-rest (BR) deconditioning influences metabolic, cardiorespiratory, and neurohormonal responses to exercise and that these effects depend on the subjects' training status, 12 sedentary men and 10 endurance- and 10 strength-trained athletes were submitted to 3-day BR. Before and after BR they performed incremental exercise test until volitional exhaustion...
The purpose of the present study was to compare the characteristics of three different exercise tests in evaluating the effects of oxitropium bromide on exercise performance. Thirty-eight males with stable chronic obstructive pulmonary disease (COPD) (FEV(1) = 40.8 +/- 16.5% predicted; mean +/- SD) completed randomized, double-blind, placebo-controlled, crossover studies for each exercise test....
the aim of this study was assessing the adjuvant therapy of exercise on cytokines balance in mice with breast cancer tumor. twenty female balb/c mice were randomly assigned to experimental and control groups. after orientation in the environment, estrogen-receptor dependent breast cancer cells (mc4-l2) were injected to them and experimental group performed endurance training 5 day in week for 6...
BACKGROUND Telomeres are potential markers of mitotic cellular age and are associated with physical ageing process. Long-term endurance training and higher aerobic exercise capacity (VO(2max)) are associated with improved survival, and dynamic effects of exercise are evident with ageing. However, the association of telomere length with exercise training and VO(2max) has so far been inconsistent...
Choline plays a central role in many physiological pathways, including neurotransmitter synthesis (acetylcholine), cell-membrane signaling (phospholipids), lipid transport (lipoproteins), and methyl-group metabolism (homocysteine reduction). Endurance exercise might stress several of these pathways, increasing the demand for choline as a metabolic substrate. This review examines the current lit...
Background Athletes demonstrate major adaptative changes in their hearts with high level of exercise. However the long term consequences of endurance training were not completely understood. We aimed to to explore the effect of long term endurance exercise on cardiac morphology and function, and diffuse fibrosis, and assess the significance of any discovered changes (correlation with documented...
STUDY OBJECTIVES The purpose of this study was to compare the effects of endurance training only to endurance plus strength (combined) training in a randomized trial of patients with COPD. METHODS Twenty-four patients completed the study: 11 patients in the combined training group (FEV(1) 45 +/- 5% predicted), and 13 patients in the endurance training group (FEV(1) 40 +/- 4% predicted) [mean ...
The purpose of this study was to determine the acute anabolic and catabolic hormone response to endurance and resistance exercise bouts of equal volume in subjects with differing training status. Twenty-two healthy men were recruited who were either resistance trained (n = 7), endurance trained (n = 8), or sedentary (n = 7). Three sessions were completed: a resting session, a 40-min run at 50-5...
Background and Objective: Sleep deprivation affects physiological and psychological functioning and probably increases the body's energy demand. It seems that sleep deprivation can have a negative effect on athletes' performance and affect the body's hormones secretion. This study investigated the effect of 24-hour sleep deprivation on endurance performance and hormonal responses to ...
