Effects of training intensity and training mode on the maximum oxygen consumption (VO_2max) compared to usual care (no exercise) subgroup analyses.

Subgroup	N° participants	d (95%CI)	p Value
Training intensity
Low- to moderate [22,30]	20	0.20 (−1.44 to 1.85)	0.81
Vigorous [23,24,29,31,32,33,34]	235	1.47 (0.60 to 2.34)	0.0009
Training mode
Continuous [22,29,30,31,32,33,34]	209	1.01 (0.19 to 1.83)	0.0157
Interval [23,24]	46	1.79 (0.28 to 3.29)	0.02

lower to moderate: 40–59% of heart rate reserve; vigorous: 60–89% of heart rate reserve; d: between-group effect size difference; I²: heterogeneity for between-studies variability.
