Exercise and Sleep in Parkinson's Disease

Summary

This study will investigate the impact of two common exercise modalities, cardiovascular and resistance training, on sleep quality and architecture in persons with Parkinson's disease (PD), and whether these potential positive changes in sleep are associated with improvements in brain plasticity and different quality of life (QoL)-related aspects. Participants will perform either cardiovascular training (CT) or resistance training (RT) for 12 weeks, at least two times/week. The assessments will be performed at baseline and after training by an assessor blinded to the participants' group allocation.
