Baecke et al developed a questionnaire for evaluating a person's physical activity and separating it into three distinct dimensions. The authors were from the Netherlands.
Indices for physical activity:
(1) work activity: 8 items
(2) sports activity: 4 items, with recording of 3 values for activity and duration of sport participation
(3) leisure activity: 4 items
Responses are assigned from 1 up to 5 points.
work index =
= ((6 – (points for sitting)) + SUM(points for the other 7 parameters)) / 8
simple sports score =
= ((value for intensity of most frequent sport) * (value for weekly time of most frequent sport) * (value for yearly proportion of most frequent sport)) * ((value for intensity of second sport) * (value for weekly time of second sport) * (value for yearly proportion of second sport))
sport index =
= (SUM(points for all 4 parameters)) / 4
leisure index =
= ((6 – (points for television watching)) + SUM(points for remaining 3 items)) / 4
• The work activity is according to the Netherlands Nutrition Council, with (1) low activity including clerical work, driving, shopkeeping, teaching, studying, housework, medical practice, and occupations requiring a university education; (2) middle activity including factory work, plumbing, carpentry, and farming; (3) high activity includes dock work, construction work and professional sport.
• The sport intensity is divided into 3 levels: (1) low level (billiards, sailing, bowling, golf, etc) with an average energy expenditure of 0.76 MK/h; (2) middle level (badminton, cycling, dancing, swimming, tennis) with an average energy expenditure of 1.26 MJ/h; (3) high level (boxing, basketball, football, rugby, rowing) with an average energy expenditure of 1.76 MJ/h
