Bell divides "meaningful activity" for post 50s into four key categories of exercise: strengthening, flexibility, aerobics and balance.
In Additional file 1 the categories of exercise-related MSI are defined on the basis of the clinical findings.
Three categories of exercise will be prescribed: ankle mobility and strengthening exercise, stepping exercise, and weight bearing and balancing exercise (see Figure 3).
Exercise " advice" implies that the GP has recommended the patient to exercise and may have provided broad categories of exercise to undertake.
They investigated many different categories of exercise, including those of differing intensity and focus; however, their findings did not translate into specific recommendations that can be used in clinical practice.
The predefined categories of exercise in the questionnaire were: aerobic for pregnant women, dance, aerobic, bicycling, walking/hiking, jogging, ball games, swimming, workout/fitness training, badminton, tennis, and horseback riding.
Participants were asked the frequency and duration (in hours and minutes) of three categories of exercise done for sport, recreation or fitness during the past 2 weeks: 1) walking, 2) any exercise causing a moderate increase in heart rate or breathing, and 3) any exercise causing a large increase in heart rate or breathing.
Body mass index (BMI; weight divided by height squared) was also included as a continuous variable, whereas the level of physical activity was estimated in three categories of exercise by duration only (less than once a week, 1 3 times a week, and > 3 times a week).
These practices have recently been characterized as "meditative movement", and constitute a distinct category of exercise [ 13].
