Abstract

International Journal of Exercise Science 12(3): 567-580, 2019. Parkinson's disease (PD) is a progressive, neurodegenerative disorder of the central nervous system that affects the elderly and results in a decrease of functional capacity, motor control, and muscle strength. Resistance training (RT) has been shown to be a non-drug alternative in both elderly and parkinsonian patients in increasing functional capacity and muscle strength. The present study aimed to verify the effects of low-volume RT in people with PD in relation to muscular strength, body composition, anthropometry and functional capacity. Fifteen elderly patients with idiopathic PD were divided into two groups: 7 in the resistance-training group (RTG): RT twice a week for 12 weeks, and 8 in the control group (CG): No exercise. Before the training period, the subjects performed maximum strength (1-RM), body composition (Bioimpedance), anthropometry, and functional capacity (GDLAM protocol) tests. The endpoints were analyzed by the Generalized Estimates (GEE) with post hoc Bonferroni, being adopted for the analyses α < 0.05. The results showed that the RTG had muscle strength gains: Bench Press 113.33%, Lat Pull Down 71.83% and Leg press 45º 94.48%, (p < 0.001), functional capacity (IG: -10.47%), and lean mass: 11.98%, (p < 0.001), while the GC presented significant changes before and after functional capacity only (GI: -1.61%) (p < 0.001). In addition, the RTG obtained reductions in the percentage of body fat (-2.30%) and in the waist-hip ratio (-2.22) without changes indicated in the CG. RT was efficient in improving muscle strength, functional capacity, body composition and anthropometric health indicators in individuals with PD.
