The level of physiological parameters during submaximal efforts expressed as percentage of maximal values in obese boys
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2009, Vol 19, Issue 48
Abstract
[b]Aim of the work.[/b] The aim of the study was to estimate the level of physiological reactions, during submaximal efforts (walking, running and cycling) in obese boys aged about 10 years.[b]Material and methods. [/b]The study was conducted on 38 boys (19 obese boys and 19 non obese). Subjects walked for six minutes on a treadmill (3,6 km • h–1 and 4,8 km • h–1), ran (7,5 km • h–1) and performed two cycloergometer tests at below and above – TDMA threshold intensities. Selected physiological reactions were analyzed during relative steady state period.[b]Results. [/b]During the treadmill tests, the level of total values of VO2 and pulmonary ventilation were higher in obese boys. The opposite results were noted for VO2 • kg–1. The heart rate was significantly higher in obese boys. During the cycloergometer tests, total values of VO2 and VE were similar in both groups. The obese boys had significantly lower heart rate.[b]Conclusions. [/b]The form of effort changes the values of differences in physiological cost between the groups. It was higher during walking and running, when surplus body weight carried by obese boys yields a higher load on their bodies. During cycling efforts the level of physiological reactions were similar in both groups.
