We included 11 r and omized controlled trials ( 331 participants ) and 2 previous systematic review s. The meta-analyses showed equal improvements in HRQoL , walking distance and exercise capacity .
In conclusion , we found significantly increased leg muscle strength favouring a combination of RT with ET compared with ET alone .
Resistance training ( RT ) is thought to be effective in preventing muscle depletion , whereas endurance training ( ET ) is known to improve exercise capacity and health-related quality of life ( HRQoL ) in chronic obstructive pulmonary disease ( COPD ) .
Our objectives were to assess the efficiency of combining RT with ET compared with ET alone .
The effects of resistance training on functional outcomes in patients with chronic obstructive pulmonary disease
Aerobic exercise training is used for rehabilitation in patients with chronic obstructive pulmonary disease ( COPD ) , although it has little effect on muscle weakness and atrophy . Resistance training may be a useful addition to aerobic programs for these patients . The purpose of the present study was to investigate the effects of resistance training in addition to aerobic training on functional outcomes in patients with COPD . Seventeen COPD patients enrolled in an aerobic-based program that met twice a week were assigned to a 12-week control/aerobic [ CON : n=8 ; 63 ( 8) years ; mean ( SD ) ] or a resistance/aerobic group [ RES : n=9 ; 61 ( 7 ) years ] . RES trained an additional twice a week on 12 resistance machines , performing three sets of 8–12 repetitions at 32–64 % of their one-repetition maximum ( 1-RM ) lifts . RES ( P<0.05 ) increased upper ( 36 % ) and lower ( 36 % ) body strength , as well as lean body mass ( 5 % ) , while CON showed little to no change . The 12-min walk distance increased ( P<0.05 ) in only the RES [ 676 ( 219 ) to 875 ( 172 ) m ] . Measurements of three of the eight tasks of activities of daily living improved in RES ( P<0.05 ) compared to CON . This study demonstrated that progressive resistance training was well tolerated and improved functional outcomes in COPD patients that were currently involved in an aerobic training program
