Differences in the level of cardiorespiratory fitness in relation to nutrition status of children in primary education

The aim of this study was to determine the level of cardiorespiratory fitness and differences according to the level of nutrition in primary education students. The study involved 212 students, of which 105 boys and 107 girls, aged 9.77 ± 0.69 years. The sample of variables consisted of anthropometric measures: body height, body weight, upper arm skin fold, back skin fold, abdominal circumference, hip circumference and WHR index. Body height was measured using an anthropometer, and body mass was measured using an Omron BF500 Body Composition Monitor. Based on the calculated body mass index, using the tables recommended by the International Obesity Task Force (IOTF), the respondents were classified into three groups according to their nutrition status. Cardiorespiratory fitness was assessed by a multi- stage 20-meter running test - Shuttle run test. The significance of differences between sub- samples formed according to nutrition status (normal body weight, overweight and obese) and cardiorespiratory fitness in primary school students was tested by variance analysis - ANOVA test. A total of 62.26% of students showed unsatisfactory levels of cardiorespiratory fitness. The results of the variance analysis (ANOVA) show that there is statistical significance between the groups categorized by the degree of nutrition in the variable for cardiorespiratory fitness assessment (p = 0.00). The results of cardiorespiratory fitness (maximum oxygen uptake-VO2max mL / kg / min) in surveyed boys were lower (45.06) compared to normative results (48.1) as well as the results in surveyed girls (44.36) compared to normative results (46.7). Normal body weight students have significantly better values of cardiorespiratory fitness than obese students. Also, overweight students have statistically significantly higher cardiorespiratory fitness scores than obese students.
