Whey protein isolate attenuates oxidative stress induced by intense exercise in trained cyclist men

Diosgenin attenuates cardiac oxidative stress in streptozotocin- induced diabetic rat

Background and Objective: Chronic diabetes mellitus (DM) leads to cardiovascular dysfunction. Diosgenin is a natural steroidal saponin with cardiovascular protective potential. In this research study, the beneficial effect of diosgenin was evaluated on some markers of oxidative stress in cardia tissue of streptozotocin (STZ)-diabetic rats. Materials and Methods: Male Wistar rats (n = 28) were ...

Whey protein isolate attenuates strength decline after eccentrically-induced muscle damage in healthy individuals

BACKGROUND We examined the effects of short-term consumption of whey protein isolate on muscle proteins and force recovery after eccentrically-induced muscle damage in healthy individuals. METHODS Seventeen untrained male participants (23 ± 5 yr, 180 ± 6 cm, 80 ± 11 kg) were randomly separated into two supplement groups: i) whey protein isolate (WPH; n = 9); or ii) carbohydrate (CHO; n = 8). ...

Exercise-induced oxidative stress affects erythrocytes in sedentary rats but not exercise-trained rats.

Oxidant stress is one of the factors proposed to be responsible for damaged erythrocytes observed during and after exercise. The impact of exertional oxidant stress after acute exhaustive treadmill running on erythrocyte damage was investigated in sedentary (Sed) and exercise-trained (ET) rats treated with or without antioxidant vitamins C and E. Exhaustive exercise led to statistically signifi...

Exercise Impairs Murine Cognitive Function Oxidative Stress Induced by Intense and Exhaustive

Oxidative stress induced by intense and exhaustive exercise impairs murine cognitive function.

It has been shown that exercise is helpful against brain disorders. However, this may not be true for intense exercise (IE). Because it is easy to misadjust exercise intensity with physical condition, it is essential to know the effects of IE on cognitive process because it may have important consequences on people skills and work skills. We investigated the effects of IE on male C57Bl/6 mice, ...
