Abstract

Background
To maintain or increase the strength of the muscles of ambulation is an important intervention in pulmonary rehabilitation, especially because the muscle strength in quadriceps shows a strong correlation with exercise capacity, quality of life and survival in patients with COPD.
Aim
To investigate whether a simple step device (SD) gives the same effects on muscular strength, work economy and pulmonary function as an established leg press (LP) apparatus using the same intensity.
Methods
20 COPD patients (FEV₁ = 48±17 %pred) participating in an in-patient pulmonary rehabilitation program were randomly assigned to LP (n =10) or SD (n =10). Both groups performed four sets of five repetitions five days a week for 4 weeks, with focus on maximal mobilization in the concentric phase of the movement. The intensity was adjusted to allow only the performance of five repetitions, corresponding to 85-90 % of 1 maximal repetition (1RM), increasing loads on the LP and making the step higher in SD. Outcome variables were muscular strength (1RM leg press), work economy and forced expiratory volume in 1 second (FEV1).
Results
Both groups had significant increases in muscle strength (LP: 19± %, SD:10± %) and work economy (LP: 17±%, SD: 18±%). There were no significant differences between the groups. Neither groups showed significant changes in FEV1.
Conclusion
The step device is a good alternative to increase muscular strength and work economy. COPD patients stay at home most of the time, without machine weights available. The results from this study give the patients and physiotherapists a simple alternative to improve the muscle strength and work economy as long as intensity correspond to 85-90 % of 1RM.
