Effects of Exercise Type on Muscle Strength and Body Composition in Men and Women: A Systematic Review and Meta-Analysis.

There are typical differences in body composition and distribution of muscle fiber types between women and men. However, research investigating the effects of exercise based on sex differences is limited, and studies examining sex differences in physiological adaptations according to exercise type are scarce. We aimed to compare the effects of exercise types on muscle strength and body composition in men and women through a meta-analysis.

Combined Low-Intensity Exercise and Ascorbic Acid Attenuates Kainic Acid-Induced Seizure and Oxidative Stress in Mice.

Physical exercise and vitamins such as ascorbic acid (ASC) have been recognized as an effective strategy in neuroprotection and neurorehabilitatioin.

After 8 weeks of swimming training, body weight decreased and endurance capacity increased significantly compared to sedentary mice.

Effect of Regular Exercise on the Histochemical Changes of d-Galactose-Induced Oxidative Renal Injury in High-Fat Diet-Fed Rats.

Renal lipid accumulation exhibits slowly developing chronic kidney disease and is associated with increased oxidative stress. The impact of exercise on the obese- and oxidative stress-related renal disease is not well understood. The purpose of this study was to investigate whether a high-fat diet (HFD) would accelerate d-galactose-induced aging process in rat kidney and to examine the preventive effect of regular exercise on the obese- and oxidative stress-related renal disease.

Exercise preconditioning reduces acute ischemic renal injury in Hsp70.1 knockout mouse.

Background/aims: Heat shock protein 70 (Hsp70) is an anti-apoptotic protein that has a protective effect in renal ischemic injury. Exercise up-regulates Hsp family proteins (Hsps), antioxidants and anti-apoptotic proteins. We hypothesized that exercise as preconditioning could attenuate acute renal dysfunction and apoptosis resulting from renal ischemic injury under the Hsp70 deficient circumstance and could contribute to the prevention of renal injury induced by ischemia.

The synergic effect of regular exercise and resveratrol on kainate-induced oxidative stress and seizure activity in mice.

The synergic effect of regular exercise and resveratrol, a polyphenolic compound with potent antioxidant activity, was investigated against kainate-induced seizures and oxidative stress in mice. After 6 weeks of swimming training, the total body weight decreased and the blood concentration of lactate stabilized statistically in comparison with the sedentary mice, indicate that the training program increased the aerobic resistance of mice. Kainate (30 mg/kg) evoked seizure activity 5 min after injection, and seizure activity was measured seizure rating scores every 5 min up to 2 h.
