| Abstract |
The aim of the present study was to determine changes occurring in the erythrocytes concentrations of chromium (Cr), manganese (Mn) and zinc (Zn) of high-level trained, moderate-level trained and sedentary man living in the same area of Extremadura (Spain). 30 sedentary subjects, with 24.34 +/- 3.02 years without sports practice and a less active lifestyle formed the control group (CG); 24 moderately trained subjects with 23.53 +/- 1.85 years, who perform between 4 and 7 hours/week of moderate sports practice without any performance objective and without following any type of systematic training formed the group of subjects with moderate degree of training (MTG) and 22 professional cyclists at the beginning of their sports season, with an age of 23.29 +/- 2.73, who performed more than 20 hours/week of training formed the high-level training group (HTG). The results showed a statistically significant lower concentration of erythrocyte Mn and Zn in the groups of athletes (MTG and HTG) than CG. We can conclude that physical training produces a decrease in erythrocyte concentration of Mn and Zn. This situation could create a reduction in the performance of athletes given the importance of the elements. For this reason, we recommend an erythrocyte control at the beginning of the training period and during the training period to avoid negative effects. |
