This study examined the acute effects of maximum strength (MS), muscular hypertrophy (MH), and strength endurance (SE) resistance exercise protocols on serum leptin. Ten young lean men (age = 23 +/- 4 yr; body weight = 79.6 +/- 5.2 kg; body fat = 10.2 +/- 3.9%) participated in MS [4 sets x 5 repetitions (reps) at 88% of 1 repetition maximum (1 RM) with 3 min of rest between sets], MH (4 sets x ...

background: heavy exercise cause muscle damage associated with production of inflammatory agents. the purpose of present study was to determine the effect of acute and 14-day coenzyme q10 supplementation on inflammatory, blood lactate and muscle damage in male middle-distance runners.   methods : eighteen male middle-distance runners in a randomized and quasi experimental study were allocated i...

Abstract An imbalance between calorie intake and energy expenditure produces obesity. It has been a major problem in societies of the developing developed world. In obesity an excessive amount fat accumulates adipose tissue cells as well other vital organs like liver, muscles, pancreas. The adipocytes contain ob genes express leptin, 16 kDa protein. present communication, we reviewed molecular ...

Maternal exercise during pregnancy has been suggested to exert beneficial effects on brain functions of the offspring. Leptin is an adipocytokine which is secreted from adipose tissues and has positive effects on learning, memory, and synaptic plasticity. In this study, pregnant rats were moderately exercised and we observed the effects of this aerobic exercise on their prepubertal and adult of...

Introduction: Leptin has been characterized as an important regulator of metabolic homeostasis, functioning in the inhibition food intake and promotion energy expenditure. resistance implicated development cardiovascular diseases obesity, exercise programs are used a therapeutic measure for these disorders, it is hypothesized that will decrease concentrations leptin blood. Methods: A comprehens...

Leptin acutely stimulates skeletal muscle fatty acid (FA) metabolism in lean rodents and humans. This stimulatory effect is eliminated following the feeding of high-fat diets in rodents as well as in obese humans. The mechanism(s) responsible for the development of skeletal muscle leptin resistance is unknown; however, a role for increased suppressor of cytokine signaling-3 (SOCS3) inhibition o...

This study investigated the effects of a long bout of aerobic exercise on hunger and energy intake and circulating levels of leptin and acylated ghrelin. Ten healthy male subjects undertook two, 4 h trials in a randomized crossover design. In the exercise trial subjects ran for 105 min at 50% of maximal oxygen uptake and the last 15 min at 70% of maximal oxygen uptake followed by a 120 min rest...

We examined the leptin response and related hormones during and after two sub-maximal exercise protocols in trained and untrained subjects. During this study, plasma concentrations of leptin [Lep], insulin [I], cortisol [C], growth hormone [GH], glucose [G] and lactate [La] were measured. 7 elite volleyball trained players (TR) and 7 untrained (UTR) subjects (percent body fat: 13.2 ± 1.8 versus...

Leptin is secreted from the edipose tissue and has an important role in the regulation of energy metabolism. This study aimed to compare serum leptin levels of preterm and full-term infants during the first three months of their life and to define the roles of sex, weight, thickness of subcutaneous adipose tissue, gestational age and maternal leptin in the determination of serum leptin levels. ...
