Rethink the effect of resistance training on six-minute walk distance?

The utilisation of resistance training in patients with chronic heart failure is an area of great interest and potential. In their recent systematic review, Hwang et al (2010) provide a clear argument supporting the hypothesis that resistance training could improve peripheral muscle strength and ultimately functional capacity in people with chronic heart failure. Their review reports the meta-analysis of randomised controlled trials; however, both the title and primary conclusion should be considered with caution.
