Implication

Randomized trial demonstrates weightlifting improves muscle endurance and symptoms in chronic airflow limitation, indicating targeted resistance training aids respiratory rehabilitation.

Key Points

To assess whether targeted upper and lower limb weightlifting exercise improves muscle strength, exercise endurance, and symptom burden in patients with chronic airflow limitation.
Randomized trial of 34 patients with chronic airflow limitation (FEV1 38% predicted), stratified by FEV1/VC ratio <40% and exercise arterial oxygen desaturation, assigned to control or weightlifting.
The experimental group engaged in upper and lower limb resistance training set to a percentage of their one-repetition maximum, conducted three times weekly for eight weeks.
Among 28 completers (14 per arm; 90% adherence in training group), cycling endurance at 80% maximum power increased by 73% in the trained group (518 [SE 69] to 898 [95] s) with no change in controls (506 [86] to 479 [89] s).
Neither group showed significant changes in maximum cycle ergometer exercise capacity or six-minute walk distance.
Trained subjects experienced significant improvements in dyspnoea and mastery of daily living activities measured by a chronic respiratory questionnaire.
