INTERVENTION: In the present study, there are two interventions: 1. Physical activity program: combined strength and aerobic training with a duration of 6 months, 3 times a week for 30 minutes. 2. Movement‐focused care: nursing staff and paramedics are trained to stimulate physical activity and independence during daily activities. Separate and combined interventions will be applied leading to four conditions: 1. Combined intervention: physical activity program and movement‐focused care 2. Physical activity program 3.
