Introduction: At physical education classes, both in elementary and second-
ary schools, some teachers evaluate tasks (eg, running at 600 m), which do not
represent movement knowledge, but above all motor skills.
The purpose of the study was to investigate the influence of body composition
dimensions and body height on 600 and 2400 m result in children of age 10 to
14 years and thus demonstrate the professional validity of the assessment of
endurance tasks.
Methods: The sample comprised 28 children – 14 boys and 14 girls. Children
were moderately active. All children took anthropometric measures and per-
formed 600 and 2400m run. We used regression analysis and multifactor anal-
ysis of covariance to investigate the influence of morphological dimensions on
children's endurance ability.
Results: Results revealed that body composition dimensions and body height
explain 76 % and 77 % of variance in 2400 m and 600 m run, respectively.
Discussion and conclusions: Body composition dimensions and body height has
a similar, but not equal, influence on efficiency of 600 and 2400 m run. High-
er children with more fat free mass achieve better results in shorter runs. In
longer runs, however, higher children with lower fat and lower fat free mass
achieve better result. The results of the study unambiguously indicate that the
evaluation of the results of the endurance runs is didactically unfounded and
probably reduces the motivation for these activities to less successful ones.
Keywords: body composition, 600m run, 2400m run, puberty,
anthropometry
