| Popis: | The increasing prevalence of childhood obesity worldwide is viewed as a global epidemic (World Health Organization, 2010). It is associated with a variety of health problems as well as physical– (cardio–respiratory endurance, flexibility, muscular strength, muscular endurance, and body composition), and motor proficiency (fine manual control, manual coordination, body coordination, and strength–and–agility) (Asayama et al., 2003:644; Okely et al., 2004:242; Tokmakidis et al., 2006:870). As far as the South African context is concerned, there is little research examining these relationships and the effect of physical intervention there upon, in nine– to 12–year old children. The first and second objectives of this study were to determine whether obesity would influence the physical– and/or the motor proficiency of nine– to 12–year–old South African children. The third and fourth objectives of this study were to determine the effect of a multidisciplinary intervention on the physical– and the motor proficiency of nine– to 12–year–old obese children. For objectives one and two, a cross–sectional study was performed on 280 children (128 boys and 152 girls), with an average age of 10.6 years (±1.05). Anthropometric–, physical– and motor measurements were obtained by the 'Fitnessgram' (Meredith & Welk, 1999) and the 'Bruininks–Oseretsky Test of Motor Proficiency–II' (Bruininks & Bruininks, 2005). Body mass index (BMI) cut–off points were used to classify the children as normal, overweight, or obese (Cole et al., 2000). The data was analysed with regard to the above–mentioned objectives with the Statistica computer program, by means of descriptive statistics, Spearman rank correlations, and variance analyses. The results show that the physical fitness variables, cardio–respiratory endurance and muscular strength, particularly leg muscular strength, showed significant decreases with an increase in BMI. A progressive, but insignificant, decrease was found in muscular endurance with an increase in BMI, while flexibility showed the weakest relationship to BMI. The motor variables strength–and–agility weakened significantly with an increase in BMI, while fine manual control, manual coordination, and body coordination showed the weakest relationships to BMI. Variance analysis showed further significant relationships among BMI, cardio–respiratory endurance, muscular strength, and running speed–and–agility (p Thesis (Ph.D. (Kinderkinetics))--North-West University, Potchefstroom Campus, 2012. |
