The Effects on Physical Activity on Mitochondrial Function in Skin Fibroblasts in Patients with Parkinson's Disease.

The Effects on Physical Activity on Mitochondrial Function in Skin Fibroblasts in Patients with Parkinson's Disease: a Study Protocol.

The aim of this study is to investigate the effect of physical activity on mitochondrial function in skin fibroblasts in patients with Parkinson's disease.

A randomized double-blind clinical trial will be conducted to study the effects of physical activity on mitochondrial function in skin fibroblasts in patients with Parkinson's disease. It is an intervention study, and twenty-four patients will be needed. Once the subjects have been selected, they will be randomly assigned into three groups (eight patients in each group). The first group will perform basic physical training (BPT) based on strength and resistance, the second group will perform BPT combined with functional exercises (BPTFE) with cognitive and motor training, and the third group will not carry out any activity program, serving as control. The interventions will last 60 minutes, with a frequency of 3 times a week, during 16 weeks. The control group will receive 4 months of PA from the program that has obtained the best results,in terms of symptoms and quality of life, after the last evaluation.
