[Approach to of the development of differenciated norms of vitamins consumption by athletes].

The equation of calculation of the norms of consumption of vitamins by athletes of different specialization is suggested. Physiological norms of consumption of vitamins by athletes of different specializations depend on the training loads that determine the amount of protein in their nutrition ration. Daily demand of the athlete in a definite vitamin is equal to the physiological norm of the demand in this vitamin of an adult person (not an athlete), multiplied by the quotient of a protein quota of the athletes' ration and physiological demand of the adult person in proteins. Application of the suggested equation allows developing balanced vitamin complexes for ath letes of various specializations.

[The effect of regular treatment with ozone on the chemical composition of potatoes and vegetables]. / Vliianie reguliarnykh obrabotok ozonom na khimicheskii sostav kartofelia i ovoshchei.

The food value of potatoes, cabbage and carrot was studied after their treatment with ozone to prolong their period of storage. The regimen of ozone-treatment of the vegetables under laboratory conditions was: 20-40 mg/m3/4 h/day/25 times. The ozonization regimen under production conditions was close to that under laboratory conditions. Ozone concentration for potatoes treatment was 20-25 mg/m3, cabbage 7-13 mg/m3, carrot 5-15 mg/m3. The investigation of the chemical composition of potatoes, carrot and cabbage after ozone action under production and laboratory conditions has shown that under the influence of ozone treatment the content of ascorbic acid decreased by 16 to 25%. Such parameters of food value as protein and starch in potatoes, and sugar and carotene in cabbage and carrot did not significantly change. The study of organoleptic properties of potatoes and vegetables did not reveal any changes as compared to nontreated products.
