Physical exercise at the crossroad between muscle wasting and the immune system: implications for lung cancer cachexia

Table 3

Exercise intensity definitions ⁷²

Metabolic equivalent of task (MET)	The ratio of the energy used up during an activity divided by the energy expended at rest (e.g. a 4 MET activity requires four times more energy than at rest).
Aerobic exercise (also named endurance activity)	Activity in which large muscles are used in a rhythmic manner. During aerobic activity, the body produce energy using oxygen (e.g. bicycling, walking, and running).
Resistance exercise	Muscles contracts and work against a force or a weight (e.g. heavy lifting, push‐ups).
Light intensity physical activity	Activity performed between 1.5 and 3 METs, without increasing heart rate (e.g. walking at a slow pace).
Moderate intensity activity	Activity performed between 3 and 6 METs.
Vigorous physical activity	Activity performed at >6.0 METs.
