title: [Vitamin and mineral status of oarsmen during the training-competition cycles].
abstract: Vitamin and minerals status of 30 sportsmen aged 16.8 +/- 0.2 years (trained in boat racing 5.0 +/- 0.3 years) during the training--competition cycles in autumn and winter has been studied. A significant decrease of vitamin A level in the range of reference limits was found in 30.8% of sportsmen during autumn season, but such decrease was revealed in 100% of examined sportsmen during winter Vitamin B1 and B2 deficiency has been detected in both seasons. The portion of persons with vitamin B2 deficiency increased during training cycles. A significant decrease of magnesium (in 56.3% of sportsmen) and sodium level (in 33.3% of sportsmen) was detected during autumn season. Irrespective of the season a significant decrease of blood serum of calcium (in 40.0-66.7% of sportsmen); potassium (in 53.3-66.7% of sportsmen according to both absolute and individual data); chlorides (in 50.0-90.0% of sportsmen), and iron (in 53.3-60.0% of sportsmen) has been revealed. The data obtained indicate the need for diagnostics and correction of vitamin and minerals status in sportsmen.
