Quetelet II Height-weight Index – BMI and Tested Physical Efficiency Referring to the Health of Boys from Małopolska
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2007, Vol 17, Issue 37
Abstract
Basing on the results of the researches conducted on 4037 boys from Małopolska in years 1996–2005 some hypothesis were verified about ontogenetic period appearance of: the negative influence of too low and too high fatness level on the positive health measures level, and the similar structure of the physical efficiency analyzed referring to health and the similar strength of the correlation connection between its elements and the height-weight index (Quetelet II) sorted in groups according to BMI level. The results of the positive health indexes were analyzed such as: the basic somatic features, antropometric indexes, the oxygen efficiency (VO2 max), motor ability tested on Eurofit and MTSF tests. Basing on the average value and the standard aberration of BMI all tested girls were divided into 3 groups: 9–10, 13–14, 17–18. In every group the range and the trend of the considering features differentiations were discerned and only in two groups (above and below the range of 1 SD BMI) the concentration analysis was conducted where the strength of the correlation connection between the elements of the physical efficiency structure, tested according to the relation of health and BMI level, were estimated.The researches confirmed the accepted hypothesis about the negative influence of low and high fatness level, tested by BMI indexes, on the selected indexes of the positive health. The results of the concentration analysis and the Pearson’s correlation between BMI index and the physical efficiency’s elements tested referring to health show the reason to claim there are similar connections between the elements of the physical efficiency and the hierarchic structure in the group of individuals of low and high fatness. The statistically essential correlations only between efficiency’s morphologic components and BMI were found. The conducted researches confirmed: 1. The negative influence of too low and too high level of fatness on the level of the health positive indexes, 2. The statistically essential correlation connections only between BMI and the somatic features which measure a body’s fatness, 3. The poor relations between BMI level and the positive health measures such as: physical efficiency, motor ability, 4. The similar structure of the physical efficiency tested referring to health in groups of lower and higher level of fatness.
