Physical Activity, Fatigue, and Sleep in People with Parkinson’s Disease: A Secondary per Protocol Analysis from an Intervention Trial

Table 2

Objective physical activity levels of participants following a 24-week exercise intervention averaged over a 24-hour period.

The exercise intervention consisted of both aerobic and anaerobic exercise training for 60 minutes, twice a week for 24 weeks. Values are medians of fraction of time spent at each level of activity using an accelerometer. A Wilcoxon signed rank test was used to determine differences between pre- and postintervention followed by a Mann–Whitney test for between-group differences, with and , respectively. Effect sizes (ES) were calculated using the equation r = Z/√N and were over time in each group. SED, sedentary activity level; LIGHT, light activity level; MOD, moderate activity level; VIG, vigorous activity level.
