BACKGROUND Exercise is beneficial to health, but during exercise the body generates reactive oxygen species (ROS) which are known to result in oxidative stress. The present study analysed the effects of vitamin E (Tri E®) on antioxidant enzymes; superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (Cat) activity and DNA damage in rats undergoing eight weeks exercise. METHODS Twe...

OBJECTIVES To compare a walking exercise to a stretching exercise during pregnancy in high-risk women who were sedentary and had previously experienced preeclampsia. METHODS A randomized clinical trial of the effects of the two types of physical exercises was conducted between November 2001 and July 2006 in Washtenaw County, Michigan. Both groups engaged in the assigned exercise five times a ...

Purpose: The present study was conducted to investigate the effect of 8 weeks resistance training with and without vascular occlusion on physical fitness indexes, growth hormone, and Insulin-like growth factor 1 (IGF-1) in male judokas.  Methods: In this quasi-experimental study, 20 male judokas were divided into two groups: 1. Traditional resistance training along with judo training with...

The aim of the present study was to evaluate the effect of regular exercise at 2, 4, 6 weeks intervals on spatial learning and memory in Morris water maze and in passive avoidance test in male diabetic rats. For this purpose, male Wistar rats were divided into four groups, two groups of control rats, one sedentary control and one swimming exercise-trained control and two groups of diabetic rats...

This study evaluated the effects of high-dose of short-term creatine supplementation (5g.kg(-1).day(-1) to 1 week) and long-term creatine supplementation (1g.kg(-1). day(-1) to 4-8 weeks) on kidney and liver structure and function of sedentary and exercised Wistar rats (Exercise sessions consisted of swimming at 80% of maximal work load supported during 5 days per week with daily sessions of 60...

objectives in this study, we aimed to investigate the changes in brain lipidomics following prolonged and intermittent ischemic preconditioning. materials and methods two groups underwent bilateral common carotid artery occlusion either intermittently (for 3 continuous periods within a timeframe of 20 minutes, releasing 3 consecutive times, yielding a total of 9 minutes (intermittent bilateral ...

Objective(s):The present study investigated the effect of long-term mild cerebral hypoperfusion induced by permanent unilateral (right) common carotid artery occlusion (UCO) on the dorsal hippocampal neurons in rats. Materials and Methods:Sixty four male Sprague-Dawley rats aged 4 months were divided into two groups of sham and UCO. These two groups were further divided into 4 sets of histopath...

Objective(s): Previous studies showed that skeletal muscle microcirculation was reduced in chronic heart failure. The aim of this study was to investigate the effects of endurance training on capillary and arteriolar density of fast and slow twitch muscles in rats with chronic heart failure. Materials and Methods: Four weeks after surgeries (left anterior descending (LAD) artery occlusion), chr...
