Convincing evidence now supports a probable preventive role for physical activity in postmenopausal breast cancer. The mechanisms by which long-term physical activity affect risk, however, remain unclear. The aims of this review were to propose a biological model whereby long-term physical activity lowers postmenopausal breast cancer risk and to highlight gaps in the epidemiologic literature. T...

The aim of the research was to assess changes in ghrelin, leptin and free fatty acids (FFA) levels in women’s blood after training. The research was carried out in women aged 45.55 ±11.33 years and with the BMI of 26.49 ±4.49. Health training at 50–66% VO2max took place twice a week for 9 months. In the baseline phase and in the 3rd, 6th and 9th month of the training, body mass and composition ...

Obesity is a worldwide epidemic that increases the risk of several well-known co-morbidities. There is a complicated relationship between adipokines and low-grade inflammation in obesity and cardiovascular disease (CVD). Physical activity practices have beneficial health effects on obesity and related disorders such as hypertension and dyslipidemia. We investigated the effects of 6 and 12 month...

OBJECTIVE To evaluate the time course of leptin, adiponectin, and resting energy expenditure (REE) responses in overweight elderly males after acute resistance exercise protocols of various intensity configurations. RESEARCH DESIGN AND METHODS Forty inactive men (65-82 years) were randomly assigned to one of four groups (n = 10/group): control, low-intensity resistance exercise, moderate-inte...

BACKGROUND This study was designed to examine the influence of exercise training on leptin levels in patients with stable coronary artery disease (CAD). METHODS Sixty-four male patients, mean age 55.6 ± 6.0 years, were randomized either to six weeks of aerobic training, three times a week, at 60-80% of maximal heart rate (training group, Ex, n = 32) or to a control group (n = 32). Exercise st...

The effect of acute exercise was studied in a group of 42 clinically healthy young Standardbred trotters. These trotters had been divided into four groups according to their age. Their ages were from 1.5 to 3 years. Three jugular venous blood samples were collected via venipuncture from each horse. These samples were collected while (1) at rest, (2) after the end of the exercise and (3) 30 min ...

BACKGROUND Cardiovascular disease is the most common cause of death in the world. The aim of this study was to determine the effect of aerobic exercise on serum inflammatory markers in untrained middle-aged women. METHODS Nineteen healthy female middle-aged were selected by convenience sampling method and were randomly divided into two experimental (n=11) and control (n=8) groups. The exercis...
