Table 1 Classification of physical activity based on MET

From: Adding exercise to usual care in patients with hypertension, type 2 diabetes mellitus and/or cardiovascular disease: a protocol for a systematic review with meta-analysis and trial sequential analysis

Metabolic Equivalent of Tasks (MET)*

Absolute intensity

1 to 1.5

Sedentary activity

1.6 to < 3.0

Light intensity activity

3.0 to < 6.0

Moderate-intensity activity

6 or higher

Vigorous intensity activity

  1. *MET is a standard unit to measure physical activity. One MET is defined as 1 kcal/kg and is approximately equivalent to the energy cost of sitting quietly [20]
