Mitchell KE, Johnson V, Houchen-Wolloff L, Sewell L, Morgan MD, Steiner MC, et al. Agreement between adherences to four physical activity recommendations in patients with COPD: Does the incremental shuttle walk test predict adherence? Clin Respir J. 2016.
There are various recommendations for physical activity (PA). However agreement between all of these measures has not been established. Furthermore, given the challenges of measuring PA there is interest in evaluating whether a measure of exercise performance can be used as a surrogate measure to identify who is likely to achieve the recommendations.
