Daily physical activity
Physical activity level was measured using the Voorrips
Questionnaire at the time of enrollment and at 12 month.
This questionnaire provides a reliable and valid method for
classifying the activity level of older subjects as high, medium or low with a score of 9.4 or less indicating a low physical level, thus classifying the subject as being sedentary.
Moreover, to ensure “realistic” conditions of training
at home, during the follow-up, the actual practice of the
physical activity were recorded: everyday, patients had to
keep track of all their activity in a diary.
