Abstract: Lack of exercise is deemed as a key factor which can cause weakness of skeletal muscle in patients with acute exacerbation of chronic obstructive pulmonary disease（AECOPD）.This review aims to synthesize current studies regarding safety，commencement，and exercise prescription of exercise therapy for AECOPD patients.The result shows that exercise therapy tends to have a higher level of safety for AECOPD patients.Additionally，Most clinical studies have shown that it is better to start exercise therapy within 48 hours after AECOPD patients are admitted to the hospital or in the period of pulmonary infection control window（PIC）.Nowadays，aerobic exercise，resistance exercise and aerobic & resistance exercise are considered as main approaches in the field of AECOPD exercise therapy.As there remains few researches on AECOPD exercise therapy so far，especially high quality ones，it is necessary to explore and develop this therapy widely and deeply in the future.
