Background:
Depression affects up to 40% of individuals with Parkinson's disease (PD).
Purpose:
To assess resistance training effects on the depressive symptoms of elderly PD patients.
Study Design:
A randomized control study.
Methods:
Thirty-three patients (aged ≥ 60 years) were randomly divided into two groups: (a) control group: n = 16 and (b) resistance training group (RTG): n = 17. All patients with Parkinson's disease (stage 1-3 on the Hoehn and Yahr scale). The RTG, in addition to maintaining their pharmacological treatments, performed 20 weeks of resistance training. The control group maintained their pharmacological treatments. Depressive symptoms, quality of life, unified Parkinson's Disease scale, and functional capacity were evaluated in both groups.
Results:
The RTG presented a significant reduction (P < .05) of depressive symptoms (pre = 17.9 ± 8 score; post = 10.3 ± 6 score; effect size: -0.48), improved quality of life (pre = 40.3 ± 21.1 score; post = 30.2 ± 16.8 score; effect size: -0.26), and improved UPDRS (pre = 64 ± 34.6 score; post = 49.1 ± 24.1 score; effect size: -0.24). No significant changes in the control group regarding depressive symptoms (pre = 18.7 ± 5.4 score; post = 19.4 ± 5.2 score; effect size: 0.07), quality of life (pre = 39 ± 16.1 score; post = 40.6 ± 15.6 score; effect size: 0.05), and UPDRS (pre = 61.1 ± 24.3 score; post = 64.9 ± 23.4 score; effect size: 0.08) after 20 weeks.
Conclusion:
Resistance training reduces depressive symptoms and improves the quality of life and functionality of elderly with PD.

The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
