Relations of Fitness Parameters and Morphological Characteristics of Seven -Year - Old Obese Children

Abstract

The aim of this research was to determine the relations of fitness parameters and morphological characteristics of seven-year-old obese children. The sample of participants consisted of 103 obese children (63 girls and 40 boys), first grade students (mean age 7,04 years) of the elementary schools in Nis. The following fitness parameters were measured: HR in load, VO2max, resting HR, bend forward -bend backward -throw test, hand taping, 20m dash with a standing start, Abalakov test and forward bend on the bench test. Morphological characteristics were determined by measuring 13 parameters of longitudinal and transversal dimensions of the skeleton, volume and body weight, as well as subcutaneous fat tissue. For all of the data we calculated the Mean and standard deviation (SD). A canonical correlation analysis was used to determine the relations between the set of variables representing fitness parameters and the set of variables of morphological characteristics. Based on the coefficients of the canonical correlation analysis, it can be concluded that the spaces of morphological characteristics and fitness parameters are interconnected with two pairs of statistically significant canonical factors (p˂.05 and p˂.01). The general analysis of the relationships between the first pair of canonical factors suggests that participants with higher circular dimensionalities of the body, accentuated adiposity and body mass tend to have poorer results in motoring tasks requiring body flexibility, explosive leg strength and running speed, and also have poorer results in the parameters of cardiorespiratory fitness. It can be concluded that obesity in younger school age has negative implications on the fitness parameters in children, and therefore on their overall growth and development.

Predicting VO2max in Children and Adolescents Aged between 6 and 17 Using Physiological Characteristics and Participation in Sport Activities: A Cross-Sectional Study Comparing Different Regression Models Stratified by Gender

“…This is an easy-to-perform test with which a large number of individuals (~10 at a time) can be tested simultaneously. Using this test, it has been shown that obese children in several countries have low VO 2 max [ 2 ], but there is a sparsity of data on cardiorespiratory fitness in relation to obesity [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. In addition, studies indicate that even maternal prepregnancy BMI is negatively correlated with cardiorespiratory fitness [ 13 ].…”

Cardiovascular Fitness in Normal Weight and Obese Children and Adolescents - A Systematic Review of Studies Published After 2000s

“…Adipose tissue is endocrinologically active and involved in the interaction between adipocytokines, insulin, and sexsteroid hormones, thereby influencing cardiovascular fitness and metabolic processes (Bunc, 2006). In that regard, Pantelic (2017) considers that excess fat tissue is an obstacle to developing fitness abilities and motor tasks, which is in accordance with another studies (Zivkovic et al, 2018;Dosic et al, 2020), who have identified that children with higher fat mass have worse results in cardiovascular endurance, leg strength, flexibility, and running speed. Hence, overall BMI values are significantly associated with cardiorespiratory fitness, and therefore, multiple included studies have confirmed this statement (Mota et al, 2006;Paschoal et al, 2009;Esmaeilzadeh & Ebadollahzadeh, 2012;Tsiros et al, 2016).…”

Franchising in the healthcare & fitness industry

“…Weight gain has a negative effect on people's physical and mental health (Wasiluk & Saczuk, 2020;Strong et al, 2005). The research results so far show that fitness is an excellent indicator and predictor of health in later life (Cvejić et al, 2013;Madić et al, 2018;Živković et al, 2018). Interest in sports activities, including fitness, has increased in recent years due to the fact that general health can be improved by improving physical fitness (Đokić et al, 2014).…”
