Exercise to Improve Sleep in Parkinson's Disease

This study will investigate the impact of three common exercise modalities, cardiovascular, resistance, and multimodal (i.e., a combination of the previous two) training, on sleep quality and architecture in persons with Parkinson's disease (PD). Furthermore, the project will investigate whether the potential positive exercise-induced changes in sleep are associated with improvements in different quality of life (QoL)-related aspects. Participants will perform either cardiovascular training (CT), resistance training (RT), multimodal training (MT), or will be allocated to a control condition (i.e., waiting list - CON) for 12 weeks. Training will be performed three times/week. The assessments will be conducted at baseline, post-intervention, and follow-up (i.e. 8 weeks after the intervention) by assessors blinded to the participants' group allocation.
