Effects of cranberry () supplementation on iron status and inflammatory markers in rowers.

Background: The aim of this study was to analyze the effect of supplementation with cranberry () on the levels of pro-inflammatory cytokines, hepcidin and selected markers of iron metabolism in rowers subjected to exhaustive exercise.

Methods: This double-blind study included 16 members of the Polish Rowing Team. The subjects were randomly assigned to the supplemented group ( = 9), receiving 1200 mg of cranberry extract for 6 weeks, or to the placebo group ( = 7).

The effect of regular exercise and massage on oxidant and antioxidant parameters.

This experimental study aimed to determine the effects of the combined application of regular exercises and massage on the values of Malondialdehyde (MDA), Nitric Oxide (NOx), Glutathione (GSH), Adenosine Deaminase (ADA) and Superoxide Dismutase (SOD). Twenty five sedentary women (32-50 years) who did not have the habit of getting regularly massages or exercising and participated voluntarily in the study. The subjects were randomly separated into three groups: control group (CG, n = 9), exercise group (EG, n = 8), and massage and exercise group (MEG, n = 8).

Influence of training frequency on serum concentrations of some essential trace elements and electrolytes in male swimmers.

Elemental fluctuations during physical performances have been a point of interest. This study was designed to investigate the effect of swimming frequency on serum concentrations of some trace elements (chromium, iron, copper, zinc, selenium) and electrolytes (sodium, magnesium, potassium, calcium). Three groups of different-level male swimmers were included in the study, as elite swimmers (n = 14), amateur swimmers (n = 11), and sedentary individuals (n = 10).
