BACKGROUND/AIMS The main purpose of this study was to investigate the effect of exhaustive exercise on L-cysteine uptake and its effect on erythrocyte glutathione (GSH) synthesis and metabolism. METHODS Rats were divided into three groups: sedentary control (C), exhaustive running exercise (ERE) and moderate running exercise (MRE) (n=12 rats/group). We determined the L-cysteine efflux and inf...

BACKGROUND AND AIMS Although acute exhaustive exercise is known to increase liver reactive oxygen species (ROS) production and aerobic training has shown to improve the antioxidant status in the liver, little is known about mitochondria adaptations to aerobic training. The main objective of this study was to investigate the effects of the aerobic training on oxidative stress markers and antioxi...

Aims: The aim of this study examined the acute effects of exhaustive incremental exercise on serum leptin, glucose and lactate in one session in trained men 18-26 years old. Materials and Methods: Thirty students who had 18-26 years old, body fat between 15-25 percent and VO2max between 35-45 ml/kg/min, simple randomly selected through 200 physical education students and they were divided into...

the aim of the present study was to examine the effect of menstrual cycle on substrate metabolism, energy expenditure and performance during exhaustive incremental exercise in female students. for this purpose, 15 female students (mean age 21.17 ± 1.47 years, bmi 20.55 ± 1.71 kg/m2) participated voluntarily in this study. the design was adjusted in three stages: bleeding, follicular and the lat...

Intravascular hemolysis is one of the most emphasized mechanisms for destruction of erythrocytes during and after physical activity. Exercise-induced oxidative stress has been proposed among the different factors for explaining exercise-induced hemolysis. The validity of oxidative stress following exhaustive cycling exercise on erythrocyte damage was investigated in sedentary and trained subjec...

Effects of continuous and intermittent trainings on exercise-induced hematuria and proteinuria in untrained adult females Sir, Exercise can induce temporary proteinuria (18–100%) and hematuria (20–100%), which usually resolve within 24–48 h [1]. Proteinuria is mainly influenced by exercise intensity rather than duration, while hematuria depends on both duration and intensity [2, 3]. Most invest...

Apoptosis or programmed cell death is a process of fundamental importance for regulation of the immune response. Several reasons suggest that apoptosis is involved in exercise-induced alterations of the immune system such as postexercise lymphocytopenia. Healthy volunteers performed two treadmill exercise tests; the first was performed at 80% maximal oxygen uptake until exhaustion (exhaustive e...

We aimed to investigate the influence of inverse moxibustion on the translocation of telomerase from cardiomyocyte mitochondria of growing mice following exercise. Sixty mice were divided into six groups (n = 10 each). For the control groups, mice were handled each day, but not subjected to moxibustion. For the inverse moxibustion groups, Guan yuan and Zusanli acupuncture points were moxibusted...

PURPOSE The central fatigue hypothesis suggests that exhaustion, or the maximum level of exercise, induces excessive stress and increases serotonin concentrations in the brain, which in turn decreases central nervous system (CNS) function and induces fatigue. Our aim was to determine the effects of colostrum serum on the serotonergic system in the dorsal raphe nuclei during exhaustive exercise....
