OBJECTIVE To evaluate the effect of prolonged intensive aerobic exercise and acute energy deficit (180 km ultra-marathon race) on serum leptin, adiponectin, resistin and visfatin levels and their association and interaction with serum cortisol and insulin levels in highly trained ultra-endurance runners. DESIGN The study included 17 highly trained ultra-endurance male athletes (mean age 51.29...

leptin is a hormone, which is secreted from fat tissue, has an important role to set cell metabolism and energy balance. the present study aims at the effect of twelve weeks high intensity interval training (hiit) on leptin level and obesity dependent factors among female students suffering overweight. in this semi-experimental study, twenty four students with bmi of 25-30 kg/m2 were selected p...

Although diet and exercise clearly have an influence on immune function, studies are scarce on the effect caused by exercise and the consumption of a carbohydrate-rich or fat-rich diet on the peripheral immune system. The aim of the present study was to evaluate the effect of exercise and the two aforementioned unbalanced diets on young Balb/c mice, especially in relation to BMI, the level of g...

Otsuka Long-Evans Tokushima fatty (OLETF) rats lacking cholecystokinin-A receptors are hyperphagic, obese, and diabetic. Although exercise attenuates OLETF rats' obesity, the mechanisms underlying the effects of exercise are unclear. In this study, we determined the effects of running wheel activity on patterns of body weight gain, food intake, and hypothalamic gene expression. We demonstrate t...

Aim of the Work: To investigate the effect of low calorie diet alone and the effect of low calorie diet and exercise on the levels of thyroid hormones, leptin, and BMI. Also we tried to investigate if there is a relation between thyroid hormones and leptin levels. Subjects and Methods: Two groups of normal male subjects, each group consists of 25 person matched for age and BMI. Group I had low ...

Changes in food reward have been implicated in exercise-induced compensatory eating behaviour. However, the underlying mechanisms of food reward, and the physiological correlates of exercise-induced changes in food reward, are unknown. Methods. Forty-six overweight and obese individuals completed 12 weeks of aerobic exercise. Body composition, food intake, and fasting metabolic-related hormones...

Halle, Martin, Aloys Berg, Ulrich Garwers, Dominik Grathwohl, Werner Knisel, and Joseph Keul. Concurrent reductions of serum leptin and lipids during weight loss in obese men with type II diabetes. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E277–E282, 1999.—The aim of the study was to examine the effects of weight reduction by exercise and diet on metabolic control in obese subjects with insu...
