The level of consumption of magnesium and iron by women and men training karate

Abstract

Introduction: The aim of the study was to evaluate the consumption of magnesium and iron in the group of women and men training karate. Methods and material: 59 women and 110 men, regularly training contact karate, were examined. The basic anthropometric parameters: body height and body mass were measured, and the body composition was assessed using the bioelectric impedance method. Consumption of energy, macronutrients as well as magnesium and iron were measured using the computer program Diet 5.0, based on prepared food interviews. Statistical analysis was based on the T-student method. Results: Men were characterized by lower fatness and higher lean body mass than women. Their intake of energy, macro and micronutrients was also higher. The amount of consumed magnesium in the group of women was 75.1% RDA, in men 90% RDA. However, iron consumption was 51.2% and 152.3% RDA in the group of women and men, respectively. Conclusions: Iron intake in the group of women and magnesium in all subjects group was too low, which may affect their physical performance as well as health. However, in the group of men the amount of iron consumed was too high. In addition, both groups had low energy intake and abnormal amounts of fat and carbohydrates, and in the group of women also proteins.
