Abstract

Background:  ‪The aim of this study was to investigate possible variations in trained children and adults in physiological, metabolic and performance factors in response to supramaximal intermittent exercise.

Material and methods: Fourteen adult trained men (eight long-distance runners and six sprinters) and seven 12-year-old trained boys performed two exercise tests on separate days: incremental cycloergometric test to determine VO2 max, AT and a supramaximal intermittent exercise (SMIE) test to determine peak power, anaerobic and aerobic capacity and also blood acidification.

Results:  ‪ ‪The results have shown similar relative values of VO2 max and total work performed in WAnT between boys and adult (p > 0.05) and significant differences in power peak between boys and sprinters. Total work in SMIE was performed at the energy cost from aerobic and anaerobic metabolism in boys and sprinters respectively: aerobic – 49% and 10%, glycolytic – 31% and 70%, phosphagenic – 20% and 20%. There were significant differences between groups in [La-], with no changes in parameters of acidification.

Conclusions:  ‪Differences between boys and adults shown under SMIE conditions are important in the practical conduct of the training appropriate to the metabolic and physical capacity of peri-pubertal boys.
