Observed Means (SD) and Intervention Effects on Peak Oxygen Uptake at the Different Measurement Occasions

	Control		Intervention		Intervention effect
	N	Observed means	n	Observed means	β (95% CI)	p Value
Over time	—	—	—	—	1.7 (0.1 to 3.4)	0.039
After intervention	37	20.5 (7.3)	35	24.8 (8.3)	2.2 (0.2 to 4.1)	0.028
6 mo after intervention	33	22.2 (8.0)	32	24.7 (8.2)	1.6 (−0.4 to 3.6)	0.116
12 mo after intervention	30	20.9 (7.3)	33	23.9 (9.4)	1.4 (−0.6 to 3.5)	0.167

The intervention effects are based on the linear mixed-model analyses.
