Peak Oxygen Uptake Responses to Training in Obese Adolescents: A Multilevel Allometric Framework to Partition the Influence of Body Size and Maturity Status

Table 1

Mean changes in body size and peak VO₂ pre- and posttraining in the obese boys (𝑛=30).

	Pretraining	Posttraining	Changes in mean 95% CL (%)	Coefficient of variation of changes in mean 95% CL (%)
Stature (cm)	158.6 (11.1)	161.0 (11.2)	1.5 (1.2 to 1.7)**	0.5 (0.4 to 0.7)
Body mass (kg)	72.4 (15.2)	70.5 (15.2)	−2.6 (−4.2 to −1.0)**	3.2 (2.5 to 4.3)
Body mass index (kg/m^2)	28.5 (3.5)	27.0 (3.8)	−5.4 (−7.0 to −3.8)**	3.2 (2.6 to 4.4)
Body mass index (z-score)	3.0 (0.8)	2.5 (0.9)	−21.5 (−28.4 to −14.1)**	18.1 (14.0 to 25.3)
Waist circumference (cm)	98.9 (10.9)	96.5 (11.4)	−2.5 (−3.4 to −1.6)**	2.7 (2.3 to 3.3)
Fat-free mass (kg)	44.8 (9.7)	45.8 (9.0)	2.6 (0.6 to 4.7)**	3.9 (3.1 to 5.2)
Fat mass (kg)	26.7 (7.9)	24.9 (9.1)	−8.8 (−12.1 to −5.3)**	8.9 (7.3 to 11.5)
Peak oxygen uptake (L/min)	2.41 (0.67)	2.65 (0.65)	10.4 (4.3 to 16.4)**	12.2 (9.6 to 16.7)
