73 patients scheduled for total hip replacement were randomized to either an intervention group, which received supervised progressive resistance training sessions twice per week and performed unsupervised home-based exercise sessions 5 times per week, or a control group, which completed daily unsupervised home-based exercise sessions only. Both groups followed their training regimen for 10 weeks postoperatively. The purpose of this study was to determine whether the intervention group, which had a combination of training sessions, had greater improvement in leg-extension power than the control group. The Nottingham Power Rig, the 20m walk test, and a hand-held dynamometer were used to assess improvement over a period of 6 months postoperatively. The results of the study demonstrated no significant improvement in the primary outcome of leg-extension power in the intervention group as compared to the control group.
