The second class (moderately active relapsers) began the CR relatively active and increased their moderate-strenuous activity during the CR.
As shown in Figure 2, the first class (Inactive Relapsers) started the CR doing very little moderate-strenuous activity.
Physical activity was measured using the Godin Leisure Time Exercise Questionnaire (LSI), focusing on moderate-strenuous activity.
Participants were assessed for their ability to achieve moderate-strenuous activity during CR and in the postrehabilitation environment.
LCGA allowed us to determine the class trajectories associated with moderate-strenuous activity and, from these, to identify implications for targeted intervention.
Very little data exist related to women's ability to achieve moderate-strenuous activity levels during CR and sustain them beyond discharge from formal programs.
*MET hours include moderate and strenuous activity to reflect the minimum guidelines of activity stated within the questionnaire (At least 30 minutes of moderate activity 4 or more times per week, or at least 10 MET hours per week).
Reviewing the average weekly duration and frequency of mild, moderate and strenuous activity, participants were performing mild activity most often (M = 32.2 minutes; M = 3.1 times/week), followed by moderate activity (M = 11.7 minutes; M = 1.1 times/week), and strenuous activity (M = 5.4 minutes; M = 0.3 times/week).
Thus, the DVD focussed on increasing activity in general, rather than emphasising moderate or strenuous activity specifically.
We observed no difference in the frequency of ST depression by diary-reported moderate to strenuous activity.
In order to comprehensively adjust for different types of physical activity, a composite index was created, which included hours per month of moderate and strenuous activity [ 30, 31].
