Effects of Different Exercise Interventions on Cardiorespiratory Fitness, as Measured by Peak Oxygen Consumption in Patients with Coronary Heart Disease: An Overview of Systematic Reviews.

Background: Exercise is an important component of rehabilitation care for people with coronary heart disease (CHD).

Objectives: The aim of this study was to critically analyze and summarize the existing evidence from published systematic reviews (SRs) and meta-analyses of randomized controlled trials (RCTs) that have evaluated the effects of different types of exercise interventions on cardiorespiratory fitness, as measured by peak oxygen consumption in people with CHD.

Methods: Electronic databases (Cochrane Library, Medline/PubMed, EMBASE, and PEDro) were searched for SRs of exercise interventions of people with CHD.

Some types of exercise interventions are more effective than others in people with coronary heart disease: systematic review and network meta-analysis.

Question: What are the effects of different types of exercise treatments on oxygen consumption, quality of life and mortality in people with coronary heart disease?

Design: Systematic review with network meta-analysis of randomised controlled trials.

Participants: Adults with coronary heart disease.

Intervention: Exercise interventions including aerobic (continuous or high-intensity interval) training, resistance training, respiratory muscle exercises, water-based exercises, yoga, Tai chi, Qigong exercises and a combination of different types of exercise.
