Table 3 Estimated maximal oxygen uptake (V̇O_2max) from the maximal watt cycle ergometer test (MWCE test) and the 20 metre shuttle run test (20 metre SRT) in Tanzanian schoolchildren, who were accustomed (AB) or unaccustomed (UB) to conventional bicycling.

Country	Sex	MWCE test V̇O_2max (ml·kg⁻¹·min⁻¹)		20 metre SRT V̇O_2max (ml·kg⁻¹·min⁻¹)
Country	Sex	AB	UB	AB	UB
Tanzania	Boys	47.3 (45.5 to 49.0)* (n = 38)	42.1 (40.6 to 43.7) (n = 43)	58.6 (57.3 to 60.0) (n = 31)	57.3 (56.6 to 58.0) (n = 51)
Tanzania	Girls	40.3 (37.2 to 43.4)** (n = 13)	36.1 (35.0 to 37.2) (n = 49)	54.7 (52.9 to 56.5) (n = 14)	55.2 (54.4 to 55.9) (n = 62)

Values are reported as means (95% CI) (n). *p<0.001; **p<0.01 from the corresponding UB value. All other differences were not significant.
