[Vitamin sufficiency of young basketball players].

The investigation of vitamin sufficiency of young basket-ball players 14-16 years old (17 girls and 14 boys) has been carried out 59-77 per cent of the children had the deficiency of B group vitamins, 24-54 per cent--vitamin E insufficiency, most of them (82-100 per cent)--deficit of carotenoids while they were sufficiently vitamins C and A supplied. The girls were supplied with vitamins better than boys. There was no one adequately supplied with all vitamins among boys while 12 per cent of girls had adequately sufficiency. The girls had deficit of 1-2 vitamins more often whereas the combined insufficiency of 3-4 vitamins took place in 1.8-2.3 fold more frequently among boys. Daily intake of multivitamin containing 10 vitamins in daily recommended doses, lipoic acid, methionin and 9 minerals by boys lead to their blood plasma vitamin C, E, B-2 and beta-carotene level increase. Vitamin C insufficiency disappeared. Deficit of beta-carotene and vitamin B-6 became 1.5 fold rarely, vitamin B-2--2 fold, vitamin E--6 fold. Thus daily intake of recommended doses of vitamins eliminates biochemical signs of vitamin deficiency.
