Rowing ergometry has not been utilized as a modality for investigating aero
bic fitness in children. This study evaluated the feasibility and reproduci
bility of measuring peak (V) over dot O-2 during progressive rowing on a Co
ncept II ergometer in 16 healthy boys aged 9-12 years. All subjects were ab
le to row effectively after minimal modeling and verbal instruction. Mean p
eak (V) over dot O-2 values on two trials were 42.9 (+/-7.9) and 41.6 (+/-
8.7) ml x kg(-1) x min(-1) (p>0.05). No significant differences were observ
ed in mean peak heart rate (190+/-11 vs. 191 +/-12 bpm), peak ventilation (
58.6+/-11.0 vs. 59.1+/-13.9 L x min(-1)), and RER (1.02+/-.07 vs. 1.02 +/-.
05) on the two trials. The coefficient of variation of peak (V) over dot O-
2 was 5.4%. These data suggest that rowing ergometry is an effective method
of measuring aerobic fitness in preadolescent boys.
