title: The general endurance of children aged 8-12 years in the 12 min run test.
abstract: The purpose of this study was to define the level of general endurance and to suggest appropriate norms in this respect. The investigation was based on a sample of over 5000 children aged 8-12 years. Their endurance was examined by means of the 12 min run test which was preceded by two months of preparatory training. The results recorded turned out to improve with age. The results achieved by the boys were on average by 272 m better than these achieved by girls. The least sex determined differences in the 12 min run performance and in somatic characteristics were observed in children aged 12 years.
