Approbation of the Ruffier Test Model Adapted for Children

Abstract The aim of the work is the experimental testing of the Ruffier test index corrected regarding to the age of patients. Four groups of patients 6, 7, 8, and 18–20 years old with 30 subjects in each of them are tested. The procedure of the study is built on the basis of the methods of theory and procedure of physical training, mathematical simulation, pulse meter, and theory of the motor tests. Mathematical statistics and corresponding methods of computer technologies are used. A statistically significant difference between resting heart rate in the groups of adults and children of 6, 7, and 8 years old is shown (p < 0.001). According to the results of one-way analysis of variance of the two-dimensional array of data, a statistically significant difference between the values of the Ruffier index (in its classical form) is revealed in the age classes that were inspected. During the correction of the value of the Ruffier index to the age of patient, the mean value of the index on the age classes statistically proved to be equal to the mean value of the index in the group of adult patients (p = 0.834). There are no significant differences between the dynamic reaction of a heart on the physical effort regarding to the age of participants (p = 0.526).
