Bangsbo (1998) which was taken as a standard (Standard).

Forwards took less vitamin B2 but statistically the result was not different from the standard menu (Student’s t-test P>0.05). Vitamin B6 intake was different for the different teams level. Soccer players from the First League ingested a higher amount than the standard menu (4.8 mg) but statistically not different (Student’s t-test, P>0.05), while teams of the other levels had lower intakes. There was no difference (Student’s t-test, P>0.05) between the results obtained for the Third Division and the standard menu. Professional soccer players ingested an equal amount of vitamin B6 while nonprofessional soccer players took significantly (Student’s t-test, P<0.05) less of this vitamin. Soccer players from the different playing positions had vitamin B6 intakes not different (Student’s t-test, P>0.05) from the standard menu, but much higher than the RDA (2.0−1) for an adult male 19 to 24 years old. Although the results obtained for the different playing positions were not statistically different (Kruskal Wallis, P>0.05) between the groups, the result obtained for the goalkeepers was lower with respect to intake of all the vitamins analysed, vitamins A, B1, B2, B6 and C (Fig. 4 and Fig. 5), than for the forwards.
