The level of realization of the nutritional standards was evaluatedusing current nutrition standards for men with high physical activity aged between 19–30 years.

Results.The average level of intake vitamin A in daily food rations of men practicing karate was 1026±513 μg. This content covered of 114% standard Recommended Daily Allowance (RDA). The level of intake vitamin E was 8.31±3.43 mg and covered 83.1% the standard Adequate Intake (AI).
