Evidence Summary (Updated 2022)
A large body of good quality randomised controlled trial study data shows an improvement in fatigue, and energy levels. Improved endurance was also found in several studies along with those found to have improved walking distances and increased exercise capacity.(1–3)
Recent review strengthens this evidence with 2 further meta-analyses. A 12 study meta-analysis (n= 463) assessed fatigue by the CRQ showing that the mixed endurance and strength intervention improved significantly more than the usual care group [SMD 0.708; 95% CI 0.510, 0.907; p < 0.001; I² = 34.3%; p = 0.116].(4)
A 15 RCT SR and MA observed a reduction in fatigue following endurance, resistance, or a combination of both exercises. There was no significant difference between continuous and interval training (n = 3 studies, SMD= −0.17, 95% CI = −0.47, 0.12, p = 0.25) or between endurance and resistance training (n = 3 studies, SMD = −0.35, 95% CI = −0.72, 0.01, p = 0.07) on fatigue in people with COPD.(5)
Quality of Evidence
Grade B – moderate quality.
Strength of recommendation
Grade 1 – strong recommendation.
Physical activity and exercise interventions may significantly improve symptoms of fatigue and improve energy levels in people with COPD.
