Exercise has been found to alter pain sensitivity with a hypoalgesic response (i.e., diminished sensitivity to pain) typically reported during and/or following high intensity exercise. Most of this research, however, has involved the testing of men. Thus, the purpose of the following investigation was to examine changes in pain perception in women during and following exercise. Seventeen health...

the purpose of this study was to investigate the effect of short term creatine monohydrate supplementation on baseline homocysteine concentrations and following an exhaustive exercise in active men. twelve male students who were members of soccer team of mazandaran university (age: 21.83±2.20 years, bmi: 13.53±58 kg/m2, homocysteine: 13.53±58 ?mol/lit) volunteered to participate in this study. ...

BACKGROUND Exercise preconditioning (EP) can provide powerful protection to the heart. Evidence supports the contention that EP directly enhances myocardial tolerance to ischaemia through a protein kinase C (PKC)-mediated mechanism. However, studies investigating the role of isoform-specific PKC after EP are lacking. METHODS AND RESULTS In this study, a male Sprague-Dawley rat model of EP was...

Exhaustive exercise may generate oxidative stress in brain and reported findings are conflicting. Long term dietary restriction (DR) may be useful in the inhibiting of free oxygen radicals generated during exhaustive exercise in the brain of rat. Hence, in this study we evaluated beneficial effects of long term DR on the oxidative stress and antioxidant enzyme systems in brain cortex and lung i...

the purpose of this research was to compare the effect of an exhaustive exercise session on the concentration of serum testosterone and cortisol and cortisol/testosterone ratio in the morning and the evening in female volleyball players. for this purpose, 12 female volleyball players (mean age 23.26 years, mean weight 58.8 kg, mean height 166.49 cm and at least four years of activity) participa...

Several studies have been shown that accelerated apoptosis is involved in post-exercise lymphocytopenia and tissue damage after high-intensity exercise. Ganoderma tsugae (GT) is one of the well-known medicinal mushrooms that possess various pharmacological functions. This mushroom has traditionally been used for health promotion purposes. This study investigates the hepatoprotective effects of...

Using an amalgamation of previously studied "train-low" paradigms, we tested the effects of reduced carbohydrate (CHO) but high leucine availability on cell-signaling responses associated with exercise-induced regulation of mitochondrial biogenesis and muscle protein synthesis (MPS). In a repeated-measures crossover design, 11 males completed an exhaustive cycling protocol with high CHO availab...

Antioxidant nutrients have demonstrated potential in protecting against exercise-induced oxidative stress. alpha-Lipoic acid (LA) is a proglutathione dietary supplement that is known to strengthen the antioxidant network. We studied the effect of intragastric LA supplementation (150 mg/kg, 8 wk) on tissue LA levels, glutathione metabolism, and lipid peroxidation in rats at rest and after exhaus...
