Effect of 6-week curcumin supplementation on aerobic capacity, antioxidant status and sirtuin 3 level in middle-aged amateur long-distance runners.

Background: The study was undertaken to evaluate the effect of 6-week supplementation with a daily dose of 2g of curcumin on VO and prooxidant/antioxidant homeostasis in middle-aged amateur long-distance runners during the preparatory period of the macrocycle.

Methods: Thirty runners were randomly assigned to a placebo group (PL) and a curcumin-supplemented group (CU). Their VO was assessed before supplementation and after 6 weeks of supplementation.

Changes in blood antioxidant status in American football players and soccer players over a training macrocycle.

Background: The effectiveness of sport training programs should be assessed regularly against biochemical indices. This study assesses changes in the antioxidant status indices in American football players (AF) and soccer players (SP) over a training macrocycle.

Methods: The study was carried out with Poland's American Football League players (AF, n = 11, age 24.

Blood serum denaturation profile examined by differential scanning calorimetry reflects the effort put into ultramarathon by amateur long-distance runners.

The impact of participation in the ultramarathon on the health and mental and physical condition is very complex. Undoubtedly, exercise brings many benefits but also involves health risks. Especially such an extreme effort as the one associated with finishing the ultramarathon run, can be dangerous to the health of the runner.

Strenuous 12-h run elevates circulating biomarkers of oxidative stress, inflammation and intestinal permeability in middle-aged amateur runners: A preliminary study.

Given the solid evidence that prolonged strenuous exercise is a cause of metabolic stress, this study sought to determine whether a 12-h run would affect total oxidant status (TOS), total oxidant capacity (TOC), total antioxidant status (TAS), high-sensitivity C-reactive protein (hs-CRP) and the biomarkers of intestinal permeability (protein fatty acid-binding proteins (I-FABP) and zonulin) in middle-aged male subjects. Ten amateur long-distance runners (aged 52.0 ± 6.

Effect of 12-Week Interventions Involving Nordic Walking Exercise and a Modified Diet on the Anthropometric Parameters and Blood Lipid Profiles in Overweight and Obese Ex-Coal Miners.

Background: Overweight and obesity after retirement are likely to be caused by unhealthy eating habits and the energy intake exceeding the energy expenditure.

Objectives: This study was designed to assess the effects of two 12-week interventions involving, respectively, either regular physical activity or a modified lower-calorie diet on the anthropometric parameters and blood lipid profiles in overweight and obese retired miners with lipid disorders.

Design: The study participants (n = 30, aged 58.
