Physical activity domains before and after a 24-week walking intervention consisting of either no-intervention control, land walking, or water walking (mean ± SD).

VPA (min/day)	0.28 ± 0.41	0.61 ± 1.46	0.60 ± 1.64	0.52 ± 0.55	0.75 ± 1.36	0.71 ± 0.98	1.30 ± 3.80	2.58 ± 7.65	2.21 ± 6.30

Note: Physical activity was measured at baseline (Week 0), following the intervention (Week 24), and after a further 24-week no-intervention period (Week 48).

^aMixed models analysis revealed a significant interaction effect for this variable from the end of the intervention to the end of the follow-up period, as discussed in the text. Abbreviations: LPA = light physical activity; MPA = moderate physical activity; MVPA = moderate-to-vigorous physical activity; VPA = vigorous physical activity.
