Eccentric exercise in adults with cardiorespiratory disease: a systematic review

Area of Science:

• Exercise physiology
• Cardiorespiratory rehabilitation

Background:

• Chronic cardiorespiratory disease impacts physical function.
• Traditional exercise interventions have limitations.

Purpose of the Study:

• To evaluate the effectiveness, tolerability, and safety of eccentric exercise for adults with chronic cardiorespiratory disease.

Main Methods:

• Systematic review of randomized, quasi-randomized, and single group cross-over trials.
• Searched multiple databases (Medline, CINAHL, Embase, etc.) up to January 2015.
• Assessed methodological rigor using the PEDro scale.

Main Results:

• Ten articles reporting on seven trials with 112 participants met inclusion criteria.
• Eccentric exercise significantly improved strength and mobility.
• It demonstrated lower oxygen consumption and higher power output compared to concentric exercise.
• No adverse events were reported; pain was managed with familiarization and tailored prescription.

Conclusions:

• Eccentric exercise is beneficial for improving walking and strength in individuals with chronic cardiorespiratory disease.
• It is well-tolerated and presents no safety concerns for this population.
• Eccentric exercise is a viable alternative or adjunct to traditional exercise regimens.
