High-intensity Functional Training on Functional and Cognitive Performance in People with Parkinson's Disease.

Parkinson's disease (PD) is a progressive and chronic neurodegenerative disease, which presents signs and symptoms both motor (impaired gait, posture, balance, etc.) and cognitive (memory loss, dementia, etc.), all of which are causing disability and assuming a high economic cost. Currently, there are already certain authors who have shown how a high-intensity interval training (HIIT) protocol produces improvements in cognitive and physical performance in healthy adults6 and in people with multiple sclerosis. However, another modality has been created, such as high-intensity functional training (HIFT), which can benefit different populations, both healthy and pathological, due to the multimodal nature of the exercises. Thanks to multimodality, more aspects such as agility, coordination and precision of movements are worked on compared to unimodal HIIT programs that make this relevant work difficult in a person's daily life. The current study aims to demonstrate the effectiveness of a HIFT training protocol in a specific population, such as people with Parkinson's disease.
