conclusions maximal and supra-maximal races induce a significant increase in lipid peroxidation and cause non-negligible inflammation and muscle damage. these effects were relatively related to the physical exercise type and the sportive specialty. results a significant increase in malondialdehyde (mda) concentrations was observed in ss and mdr after the vameval test and in ldr after the limite...

introduction: the use of antioxidants before high-intensity training, which leads to the release of free radicals and muscle injuries, can result in reduced damage during exercise. accordingly, in this study, we aimed to evaluate the effect of selenium supplement intake on oxidative stress, following exhaustive aerobic exercise among young physically-active females. methods: in this quasi-exper...

Objective: Very recent studies have reported positive effects of dietary nitrate on the oxygen consumption during exercise. This research aimed to study the effect of moderate dose of high-nitrate vegetables, watercress (Nasturtium officinale) and red radish (Raphanus sativus) compared with a control group on the incremental treadmill exercise test following a standard Bruce protocol controlled...

[Purpose] VO2 is expressed as the product of cardiac output and O2 extraction by the Fick equation. During the incremental exercise test and constant high-intensity exercise test, VO2 results in the attainment of maximal O2 uptake at exhaustion. However, the differences in the physiological components, cardiac output and muscle O2 extraction, have not been fully elucidated. We tested the hypoth...

to investigate the effect of vitamin e supplementation on the response of intercellular adhesion molecule-1 (icam-1) to exhaustive exercise, 16 active men were selected and divided into supplementation and placebo groups based on vo2max. the subjects in each group completed 65 minutes of exhaustive exercise after14 days of supplementation. blood samples were collected before supplementation and...

The plasma ammonia response to exercise in chronic obstructive pulmonary disease (COPD) was examined and the relationship between plasma ammonia concentration and muscle adenine nucleotide metabolism was explored. In total, 25 stable COPD patients and 13 similar-aged controls underwent incremental and constant-work rate cycle exercise tests. Arterialised venous blood was sampled at rest, at 1-m...
