In the study, the authors address the relationship between health-oriented physical fitness (Ruffier test, Beep test) and the body mass index (BMI) in a school population of boys and girls of a younger school age. The research was conducted on a sample of n = 247 boys and girls from elementary schools in the Upper Nitra region. They compared n = 119 boys and n = 128 girls. Boys and girls from elementary schools in the Upper Nitra region were divided into 4 groups based on the BMI index for the population of 10-year-old boys and girls in Slovakia according to Ševčíková et al., (2004) and compared their level of health-oriented fitness (Ruffier test index). They also assessed the body posture of boys and girls using the standardized method according to Thomas-Klein mod. Mayer (Bendíková, 2016). To determine the statistical significance of the samples, they used the Kruskal-Wallis H-test and Mann-Whitney U-test. They used Cohen’s d and r to evaluate the effect size and the difference in average values. By evaluating the results of the BMI index and health-oriented fitness depending on physical fitness and aerobic endurance of boys and girls from elementary schools in the Upper Nitra region, they found a significant decrease in physical fitness among boys and girls. As the BMI index increased, physical fitness (Ruffier test) decreased significantly by an average of 3.4 (index) (14.84%) in the observed group of boys and 4.03 (index) (15.86%) in the observed group of girls. Aerobic endurance (Beep test) also significantly decreased with increasing BMI index, with an average difference of 6.16 (number) (15.17%) in boys and a significant decrease of 4.26 (number) (13.69%) in girls. They also consider it concerning that only 25 boys (21%) had good body posture (Level 1 and Level 2), while 94 boys (79%) had incorrect body posture (Level 3 and Level 4). Good body posture (Level 1 and Level 2) was found in 22 girls (17.18%), while 106 girls (82.82%) had incorrect body posture (Level 3 and Level 4). Based on these findings, they consider the current state of the BMI index, health-oriented fitness (Ruffier test and Beep test), and body posture of boys and girls from elementary schools in the Upper Nitra region to be unsatisfactory and detrimental to health. These facts need further analysis and the implementation of systematic preventive measures. VEGA 1/0427/22.

摘要

In the study, the authors address the relationship between health-oriented physical fitness (Ruffier test, Beep test) and the body mass index (BMI) in a school population of boys and girls of a younger school age. The research was conducted on a sample of n = 247 boys and girls from elementary schools in the Upper Nitra region. They compared n = 119 boys and n = 128 girls. Boys and girls from elementary schools in the Upper Nitra region were divided into 4 groups based on the BMI index for the population of 10-year-old boys and girls in Slovakia according to Ševčíková et al., (2004) and compared their level of health-oriented fitness (Ruffier test index). They also assessed the body posture of boys and girls using the standardized method according to Thomas-Klein mod. Mayer (Bendíková, 2016). To determine the statistical significance of the samples, they used the Kruskal-Wallis H-test and Mann-Whitney U-test. They used Cohen’s d and r to evaluate the effect size and the difference in average values. By evaluating the results of the BMI index and health-oriented fitness depending on physical fitness and aerobic endurance of boys and girls from elementary schools in the Upper Nitra region, they found a significant decrease in physical fitness among boys and girls. As the BMI index increased, physical fitness (Ruffier test) decreased significantly by an average of 3.4 (index) (14.84%) in the observed group of boys and 4.03 (index) (15.86%) in the observed group of girls. Aerobic endurance (Beep test) also significantly decreased with increasing BMI index, with an average difference of 6.16 (number) (15.17%) in boys and a significant decrease of 4.26 (number) (13.69%) in girls. They also consider it concerning that only 25 boys (21%) had good body posture (Level 1 and Level 2), while 94 boys (79%) had incorrect body posture (Level 3 and Level 4). Good body posture (Level 1 and Level 2) was found in 22 girls (17.18%), while 106 girls (82.82%) had incorrect body posture (Level 3 and Level 4). Based on these findings, they consider the current state of the BMI index, health-oriented fitness (Ruffier test and Beep test), and body posture of boys and girls from elementary schools in the Upper Nitra region to be unsatisfactory and detrimental to health.
