Abstract
The purpose of this study was to assess differences in peak performance measures between three different age groups: 6 to 8 years, 9 to 10 years, and 11 to 13 years. Each child underwent a progressive maximal bicycle test. Measures such as oxygen consumption ([Vdot]O2), ventilation ([Vdot]E BTPS), heart rate (HR), respiratory exchange ratio (R), and work rate were continuously monitored. Peak cardiac output ([Qdot]), stroke volume (SV), and arteriovenous oxygen difference a-v O2 diff) were indirectly determined during the last 15 sec of exercise using a CO2 rebreathing method. Peak measures for [Vdot]O2 (1/min), [Vdot]E BTPS (1/min), and work rate (kpm/min) increased with age such that each was statistically different (p b.05) among age groups. No statistical differences among age groups were found for [Vdot]O2 (ml/kg body wt/min), R, [Qdot], SV, and a-v O2 diff. It was concluded that peak [Vdot]O2 (1/min) differs among age groups in young children but not when expressed in ml/kg body wt/min. In addition, peak [Vdot]E BTPS and work (kpm/min) also differ among children of young ages.
