Metabolic Responses to Reduced Daily Steps in Healthy Nonexercising Men

JAMA. 2008;299(11):1261-1263. doi:10.1001/jama.299.11.1259

To the Editor: Increased daily physical activity is associated with improved health,1 but it is uncertain whether it prevents initial metabolic events that produce chronic diseases. We are aware of no evidence in healthy, young adults that reduced daily stepping within a free-living environment is associated with negative metabolic consequences. The purpose of this study was to reduce daily steps and assess metabolic changes.
