Table 2. The physical dose of structured exercise intervention. Data is shown as mean (standard deviation).

Determinants of physical activity	Resistance training group		Nordic walking group
	Excluded (n = 28)	Included (n = 8)	Excluded (n = 32)	Included (n = 7)
Adherence (%)	65(24)	78 (15)	65 (18)	65 (30)
Absolute intensity (MET)	3.3 (.5)	2.8 (.3)*	5.9 (.4)	5.2 (1.5)†
Relative intensity (%)	43.3 (11.1)	35.8 (6.4)	71.8 (14.0)	67.0 (24.5) †
Volume (METh·wk-1)	10.5(1.7)	6.8 (1.8)*	15.5 (2.9)	12.3 (6.3)

MET = metabolic equivalent of task; METh = MET-hours; Relative intensity = percentage of absolute intensity from the individual VO_2peak expressed in MET-values.*p-value < 0.050 compared to the excluded in the particular group.† p-value < 0.050 compared to the included resistance training group.
