This study was undertaken to investigate physiological adaptation with two endurance-training periods differing in intensity distribution. In a randomized crossover fashion, separated by 4 wk of detraining, 12 male cyclists completed two 6-wk training periods: 1) a polarized model [6.4 (±1.4 SD) h/wk; 80%, 0%, and 20% of training time in low-, moderate-, and high-intensity zones, respectively];...

Introduction: Most neurodegenerative diseases are associated with the disruption of axonal transport and this might also be related to diabetes-associated disorders affecting the nervous system. Cytoplasmic dynein is a very important motor driving the movement of a wide range of cargoes toward the minus ends of microtubules. The effects of endurance training on dynein motor protein expression i...

Background: Chronic use of dexamethasone, especially in athletes, is associated with reproductive disorders. Objectives: This study aimed to investigate the effect high and moderate intensity endurance training along consumption safflower extract on testicular oxidative damage testosterone level male rats treated dexamethasone. Methods: A total 45 Wistar were divided into controlled groups. Dex...

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...

BACKGROUND: The purpose of this study was to determine the effects of hypoxic training on the cardiorespiratory system and skeletal muscle among well-trained endurance athletes in a randomized cross-over design. METHODS: Eight junior national level competitive cyclists were separated into two groups; Group A trained under normoxic condition (21% O2) for 2 hours/day, 3 days/week for 3 weeks whil...

obesity is accompanied with renal dysfunction, so renal impairment is more prevalent in obese people. renal function can be assessed via markers such as cystatin c (cys c), creatinine (crn) and glomerular filtration rate (gfr). as the effect of exercise training on renal function has been less investigated, this study aimed to study the effect of eight weeks of aerobic training and 10 days of d...

Objective: The aim of this study was to compare the three endurance training intensities on the expression of Perlipin A protein in subcutaneous adipose tissue and pancreatic B-cells function in male diabetic rats. Materials and Methods: In this study, 40 healthy male wistar rats were divided into five groups, including diabetic with low intensity endurance training, diabetic with moderate int...
