Abstract

Aim The aim of this survey is to examine the effects of physical training on erythrocyte membrane fatty acids percentages as well as to analyze cellular adaptations in young sportsmen. Methods Forty-four male volunteers participated: a group of 22 trained players (TG) (age: 17.86 ± 0.36 years; weight: 69.86 ± 4.53 Kg; height: 1.78 ± 0.54 m), with a regular football training plan of 10 hours/week, and a group of 22 untrained participants (UG) (age: 18.23 ± 0.49 years; weight: 72.10 ± 8.56 Kg; height: 1.68 ± 0.39 m). Gas chromatograph HP-5890 Series II was used to determine fatty acids concentrations. Results Higher levels were obtained in the TG group in C12:0 (0.31 ± 0.35 vs. 0.03 ± 0.04%, P < 0.001) and in n-6/n-3 index (8.74 ± 5.20 vs. 4.29 ± 1.09, P < 0.001), and lower values in C22:6 (3.00 ± 3.51 vs. 5.08 ± 1.44%, P < 0.01) in comparison with the UT group. Moreover, a correlation of these parameters and the Lipid Peroxidation index with training degree were observed. Conclusion 10 hours/week aerobic-anaerobic football training program produces C12:0, n-6/n-3 index, C22:6 modifications in erythrocyte membrane.
