We studied whether disabled older
women with coronary heart disease can perform resistance training at an
intensity sufficient to improve measured and self-reported physical
function [n = 30, 70.6 ± 4.5 (SD) yr].
Compared with the controls, the resistance-training group showed
significant improvements in overall measured physical function score
using the Continuous-Scale Physical Functional Performance Test (+24
vs. +3%). The Continuous-Scale Physical Functional Performance Test
measures physical function for 15 practical activities, such as
carrying groceries or climbing stairs. Resistance training led to
improved measures for domains of upper body strength (+18 vs. +6%),
lower body strength (+23 vs. +6%), endurance (+26 vs. +1%), balance
and coordination (+29 vs.
2%), and 6-min walk (+15 vs. +7%). Women
involved in the flexibility-control group showed essentially no
improvement for physical function measures. No changes were observed
for body composition, aerobic capacity, or self-reported physical
function in either group. In conclusion, disabled older women with
coronary heart disease who participate in strength training are able to
train at an intensity sufficient to result in improvements in multiple
domains of measured physical functional performance, despite no change
in lean body mass.
