overweight and elevated bmi can increase the risk of breast cancer in postmenopausal women. on the other hand, it seems that exercise training affect weight and bmi. the aim of this study was to investigate the effects of exercise training on some anthropometric variables in postmenopausal women with breast cancer. thus, 29 postmenopausal women with breast cancer who received surgery, chemother...

Endurance exercise training enhances muscle fat oxidation while concomitantly reducing carbohydrate (glycogen) utilization during exercise, thereby delaying the onset of fatigue. This study examined effects dietary restriction on endurance training-induced metabolic adaptations in rat skeletal muscle. Male Sprague-Dawley rats were placed either a control diet (CON: 19.2% protein, 21.6% fat, and...

introduction: cardiac remodeling after myocardial infarction, is associated with progressive ventricular dysfunction and cardiovascular death. the purpose of this study was to examine the effect of endurance exercise training on morphological changes in rat heart tissue following experimental myocardial infarction. materials and methods: rats used in this experiment (8-10 weeks old, 235 ± 5 g b...

OBJECTIVE To determine the effects of an endurance training program on the exercise capacity and muscle structure and function in individuals with postpolio syndrome. DESIGN Preexercise and postexercise testing was performed with muscle strength evaluations using isokinetic testing as well as hand-held Myometer. Muscle fatigue was determined by use of isokinetic testing, and endurance was det...

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...

BACKGROUND Few data are available about the effects of respiratory muscle training with normocapnic hyperpnea (NH) in COPD. The aim is to evaluate the effects of 4 weeks of NH (Spirotiger(®)) on ventilatory pattern, exercise capacity, and quality of life (QoL) in COPD patients. METHODS Twenty-six COPD patients (three females), ages 49-82 years, were included in this study. Spirometry and maxi...

BACKGROUND Respiratory muscle endurance training (hyperpnea training) has been shown to have beneficial effects in patients with COPD. STUDY OBJECTIVES The purpose of this study was to determine whether hyperpnea training, when added to an endurance exercise training program, would lead to additional benefits compared with endurance training alone in patients with COPD. SETTING AND PARTICIP...
