Table 2 Calculation of total, occupational, sports and household PA levels
From: Physical activity levels after low anterior resection for rectal cancer: one-year follow-up
Definition | Example | Formula |
|---|---|---|
occupational PA level | - A patient worked 38 h/week with 20% light, 70% moderate and 10% vigorous activities. | - occupational: (38 h/week × 20% × 2 MET) + (38 h/week × 70% × 3 MET) + (38 h/week × 10% × 4 MET) = 110 MET-hours/week |
- He drove 1.3 h/week for work by car. | - activity level for transport for work: 1.3 h/week × 1.5 MET = 2 MET-hours/week | |
sports PA level | This patient performed two sports. | (2 h/week × 5.5 MET) + (0.7 h/week × 3.5 MET) = 13 MET-hours/week |
household PA level | He also performed 10 h/week light, 4 h/week moderate and 1.5 h/week vigorous household activities. | (10 h/week × 2.5 MET) + (4 h/week × 3.5 MET) + (1.5 h/week × 4.5 MET) = 46 MET-hours/week |
total PA level | occupational + sports + household PA levels (explained above) + active transport in leisure time (1.0 h/week × 4 MET) + eating (8.8 h/week × 1.8 MET) + sleeping (49 h/week × 0.9 MET) + quiet leisure time (47.7 h/week × 1.5 MET) = 307 MET-hours/week |
