Exercise and life expectancy

摘要

We were pleased to read Chi Pang Wen and colleagues' report of reduced mortality and extended life expectancy with even low levels of physical activity. Owing to understandable limitations, the research only assessed leisure-time physical activity (LTPA); however, Wen and colleagues expand their discussion beyond this type of activity to say "of the four domains of physical activity (work, transportation, household, and LTPA)...LTPA is the most related with health benefits. Furthermore, only LTPA is effort-related and promotable."
