Background: During childhood and adolescence, the behavior of VO2max is related to morphophysiological changes attributed to the process of biological maturation. It is also determined by the level of physical training.
Purpose: The objective was to characterize the peak oxygen consumption (VO2peak) in adolescents
Methods: Cross-sectional descriptive study in Bogotá D.C was carried out, with a population of 51 untrained (UT n = 21) and endurance sports trained (T n = 30) adolescents. Training level, anthropometric measurements, stage of biological maturation, peak / maximal oxygen consumption (VO2peak/max) were assessed through direct ergospirometric tests and hematological variables.
Results: VO2peak was higher in group T (45.7 ml / kg / min) than in UT (36.5). For both groups, the men got higher values than the women (p 0.05), difference was greater in T. A positive correlation was found between VO2peak and MLG (r = 0.558; p = 0.001).
Conclusion(s): In stages 4 and 5, the consolidation of the physiological changes in men and women determines that there is not an evident relationship between VO2peak and maturation. Factors directly related to VO2peak were age and fat free mass and indirectly were fat weight and sex.
Implications: The evidence on the behavior of VO2peak in T and UT adolescents is limited, therefore these findings will allow to establish individual criteria for the evaluation and prescription of endurance exercise according to the individual and biological variability of the population.
