Fitness in midlife may lower men's risk of cancer
Is there a relationship between cardiovascular fitness and cancer? A research team noted that few studies had looked for a connection. To understand the results of their analysis, keep in mind that a metabolic equivalent (MET) is defined as 1 kcal/kg/hour, or about the energy cost of sitting quietly. Without taking age or physical condition into account, walking around the house is about 2.0 METs and walking down stairs is about 3.5 METs (Compendium of Physical Activities 2011).
