title: [Protein intake in selected youth groups of different physical activity and requirements for athletes].
abstract: The aim of the study was to investigate protein intake in groups of different physical activity. The research was undertaken over a group of young people of different physical activity (age group 15-18 years) including ballet dancers, karate fighters, cross runners as well as adolescents of average physical activity (female and male). The investigation was performed in two series. The first--before intense exercise training and the second--after intense exercise training. In control group there was only one series. Urea was estimated by using urease which converts urea into ammonia, CO2 and glutamic dehydrogenase reaction via measurements of ammonia derived from urea. The amounts of urea were applied for counting quantity of consumed proteins. In the physically active groups the protein intake was too low in comparison to required.
