Abstract
Ruffier – Dickson test is a popular method in school physical education because of a simple
procedure and apparatuses, good reliability and validity in evaluation of physical capacity. It
is well-known in sports and physical rehabilitation too. The aim of the research is to prepare a
model of Dickson index, which should be suitable for school physical education. Two ways to
reach this purpose, taking into account a normal heart rate in rest corresponding to pupil’s age
(70–102 min-1), are proposed. They are a model of correction of Dickson index formula and a
model of correction of assessment gradations. A ratio of a normal heart rate in rest of school
age pupils and adults should be accepted as a parameter of correction of Dickson index
formula. Three measures of heart rate values in Ruffier – Dickson test should be reduced
proportionally to this ratio. Application of the corrected formula results in a statistically
significant improvement in assessment of young patients’ cardiovascular system state
(p < 0.01). The results of modeling are presented in simple tabular and graphical forms that
are suitable for humanists who are unready to use mathematical methods.
