Abstract
The transient oxygen uptake (VO2) response during the initial phase of exercise was investigated in 28 children (mean age ± SD = 10.2 ± 2.28 years) during constant load submaximum bicycle ergometer exercise (mean power output ± SD = 56 ± 4.0 watts; mean VO2 ± SD =.92 ±.141 ṁ min-1). The VO2 half-time (VO2 - t½) averaged (± SD) 34.8 (± 12.70) sec which is similar to that observed in adults. Examination of the VO2-t ½ response as it related to age (7 to 14 years) showed that younger children attained steady-rate VO2 more quickly than older children (r =.77 between age and VO2-t½, P <.05). Body size, maturational level, exercise intensity, cardiorespiratory factors, and anaerobic potential are suggested as possible factors accounting for the positive age vs VO2-t ½ relationship.
