Effects of Strength Training on Muscle Properties, Physical Function, and Physical Activity among Frail Older People: A Pilot Study

Table 2

Pre- and posttest results of physical function for the ST and CON.

Tests	Group	Pretest	Posttest
Stair climbing (sec)	ST	26.0 ± 6.0	19.3 ± 3.4
	CON	18.3 ± 3.6	17.1 ± 3.3
Preferred walking speed (km/h)	ST	2.3 ± 0.3	2.3 ± 0.2
	CON	3.0 ± 0.3	2.9 ± 0.3
Maximal walking speed (km/h)	ST	3.5 ± 0.3	3.8 ± 0.4
	CON	4.5 ± 0.4	4.3 ± 0.4
Rising from a chair (sec)	ST	27.6 ± 4.6	25.5 ± 4.1
	CON	20.6 ± 2.2	19.1 ± 2.3

ST = strength-training group; CON = control group; sec = seconds; km/h =kilometres per hour; all values are presented as mean ± standard error.
