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

Effectiveness of a High-intensity Functional Training (HIFT) Program 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.

The hypothesis is that high-intensity functional training (HIFT), at a motor and cognitive level, provides a greater benefit than conventional programs of strength, balance and cognition, on the functionality and cognitive capacity of people with Parkinson's disease.

Overall objective:

- To assess whether the HIFT training program is associated with significant improvements in functional and cognitive capacity compared to conventional strength, balance and cognition programs in Parkinson's patients.

Secondary objectives:

1. To assess whether the HIFT program improves the quality of life in patients with PD.
2. To study whether the HIFT program reduces the degree of dependency of patients with PD.
3. To determine if the HIFT program improves physical performance in patients with PD
4. To assess whether the HIFT program reduces the risk of falls in patients with PD.
5. To investigate whether the HIFT program improves balance in patients with PD.
6. To determine if the HIFT program improves functional capacity in patients with PD.
7. To study whether the HIFT program improves cognitive function in patients with PD
