Acute antioxidant supplementation improves endurance performance in trained athletes.
This study examined the acute effects of a single dose of an antioxidant (AO; Lactaway® containing pycnogenol) on time to fatigue (TTF). Nine trained cyclists [mean ± SD age 35 ± 10 yrs; body mass 71.6 ± 10.2 kg; VO2 peak 63 ± 11 ml/kg/min] performed on two separate occasions a continuous protocol of 5 min at 50% of peak power output (PPO), 8 min at 70% of PPO, and then cycled to fatigue at 95%...
متن کاملAntioxidant diet supplementation influences blood iron status in endurance athletes.
OBJECTIVE The aim of this work was to check the effects of antioxidant supplementation (vitamins E and C, and beta-carotene) on the basal iron status of athletes prior to and following their training and competition season (3 months). DESIGN Eighteen amateur trained male athletes were randomly distributed in 2 groups: placebo (lactose) and antioxidant supplemented (vitamin E, 500 mg/d; vitami...
متن کاملAntioxidant Effects of Vitamins C and E on the Low-Density Lipoprotein Oxidation Mediated by Myeloperoxidase
Background: Oxidative modification of low-density lipoprotein (LDL) appears to be an early step in the pathogenesis of atherosclerosis. Meanwhile, myeloperoxidase (MPO)-catalyzed reaction is one of the potent pathway for LDL oxidation in vivo. The aim of this study was to evaluate in vitro antioxidant effects of vitamins C and E on LDL oxidation mediated by MPO. Methods: MPO was isolated from f...

متن کاملHigh density lipoprotein metabolism in endurance athletes and sedentary men.
BACKGROUND Endurance athletes have higher high density lipoprotein (HDL) concentrations than sedentary controls. To examine the mechanism for this effect, we compared HDL apoprotein metabolism in 10 endurance athletes aged 34 +/- 6 years (mean +/- SD) and 10 sedentary men aged 36 +/- 8 years. METHODS AND RESULTS Subjects were maintained on controlled diets for 4 weeks, and metabolic studies u...
