Background: The balance between production of Reactive Oxygen Species (ROS) and antioxidant defense in the body has important health implications. The aim of this study was to investigate the changes in salivary antioxidants: catalase, vitamin C and brain-derived neurotrophic factor (BDNF), in sedentary men at rest and after acute exhaustive exercise.   Methods: This randomi...

hemorheology specialists believe that athletes of different sport fields have different hemorheological patterns. the aim of this study was to investigate the effect of sport field on hemorheological variables following acute aerobic exercise. athletes were divided into three groups of 15 subjects (endurance runners: mean±sd: age 24.6±5.2 yr, bf% 6.8±1.6, bmi 21±1; football players: age 22.5±1....

Introduction: Visfatin is predominantly secreted from visceral adipose tissue and mimics the effect of insulin by binding to insulin receptors. The purpose of the present research is to examine the effect of glucose intake on plasma visfatin concentration following an aerobic exercise session. Methods: In a quasi-experimental study, 16 male non-athlete students (21.91±2.31 yrs., 77.53...

the aim of this study was to investigate the effect of acute plyometric exercise with and without vitamin c supplementation on serum bdnf concentration in inactive men. in this semi-experimental study, 36 inactive men were randomly divided into four groups: vitamin+exercise (combination), vitamin c, exercise, and control. the exercise and combination groups performed the selected plyometric pro...

PURPOSE Physical exercises are employed as part of the treatment of patients with chronic obstructive pulmonary disease (COPD); however information regarding cardiac autonomic modulation after an acute session of resistance exercise (RE) is unknown. The aim of this study was to evaluate the cardiac autonomic modulation, via heart rate variability after an acute session of RE applied at differen...

We compared the acute response of anorexigenic signals (total PYY and GLP-1) in response to submaximal and supramaximal exercise. Nine females completed three sessions: (1) moderate-intensity continuous training (MICT; 30 min; 65%  VO2max); (2) sprint interval training (SIT; 6 × 30 sec "all-out" cycling sprints with 4 min recovery); or (3) control (CTRL; no exercise). PYY and GLP-1 were measure...

Hypertension is epidemic disease which post-exercise hypotension (PEH) is useful strategies for hypertension. The aim of present study was to investigate the effects of resistance exercise leading to failure (REF) and resistance exercise not to failure (NREF) on PEH phenomenon in trained men. Eight trained men (age: 22.12±1.81 yr; height: 179±3.44 cm; weight: 73.82±4.29 kg;...
