Background:
The objective of this study was to investigate the benefits of a low volume outpatient whole body vibration training (WBVT) program on exercise capacity in comparison to a calisthenics training program (CTG) in subjects with chronic obstructive pulmonary disease (COPD).
Methods:
In this single-centre randomized controlled trial twenty-nine subjects with mild to severe COPD were randomized to WBVT or to calisthenics training including relaxation and breathing retraining in combination with calisthenics exercises. Both groups equally exercised for duration of 3 months with 2 session/30 min per week). Outcome parameters were 6-minute walk distance (6MWD, primary outcome), 5 Repetition sit-to-stand test (STST), leg press peak force, Berg-Balance scale (BBS), St. George Respiratory Questionnaire (SGRQ) and COPD-Assessment-Test (CAT).
Results:
Twenty-seven subjects completed the study (WBVT: n = 14, CTG: n = 13). Baseline characteristics between groups were comparable. Subjects in the WBVT group significantly improved 6MWD (+105 [45.5 – 133.5] m; p = 0.001), STST (-2.3 [-3.1 – 1.3] s.; p = 0.001), peak force (28.7 [16.7 – 33.3] kg; p = 0.001) and BBS (1.5 [0.0 – 4.0] pts; p = 0.05). Changes in 6MWD, STST and leg press peak force were also found to be significantly different between groups in favor of the WBVT-group. Only the between-group difference of the CAT score was in favor of the CTG (p = 0.024).
Conclusion:
A low volume WBVT program resulted in significantly and clinically relevant larger improvements in exercise capacity compared to calisthenics exercises in subjects with mild to severe COPD.
