The aim of the study was to determine the physical, physiological and nutritionalcharacteristics of female futsal players and selected markers of oxidative stress after their exercise training (Loughborough Intermittent Shuttle Test). Eight health female futsal players (age 21.3 ± 3.2 years, body mass 64.5 ± 5.6 kg, height 169.5 ± 6.5 cm, body mass index 22.45 ± 2.25 kg/m2;mean ± SD) participated in this study. Blood samples were collected before, during and immediately after the exercise for glucose, lactate, ascorbic acid, total plasma antioxidant potential, lipid hydroperoxides, malondialdehyde and creatine kinase concentrations. Female futsal players appeared to meet caloric needs but failed to meet minimum carbohydrate and vitamin A, C and E recommendations. Immediately after the exercise there were an increase in lipid hydroperoxides (ranging from 9.32 ± 1.86 μmol?L–1 to 13.02 ± 1.62 μmol?L–1, p –11 to 3.29 ± 0.62 nmol?L–1, p –1 to 185.59 ± 6.96 U.I..L–1, p < 0.05). In parallel, ascorbic acid and total plasma antioxidant potential had a slight decrease during and after exercise. Considering that alterations in oxidative stress parameters associated with inadequate ingestion of nutrients can affect health and performance of game players, further studies are needed to evalu- ate the inclusion of an nutritional education program and extent of biochemical changes through athlete’s recovery pe- riod.
