Abstract
BACKGROUND: Physical activity in the elderly is recommended by international guidelines to protect against cognitive decline and functional impairment. OBJECTIVE: This Randomized Controlled Trial (RCT) was set up to verify whether medium-intensity physical activity in elderly people living in the community is effective in improving cognitive performance. DESIGN: RCT with parallel and balanced large groups. SETTING: Academic university hospital and Olympic gyms. SUBJECTS: People aged 65 years old and older of both genders living at home holding a medical certificate for suitability in non-competitive physical activity. METHODS: Participants were randomized to a 12-week, 3 sessions per week moderate physical activity program or to a control condition focused on cultural and recreational activities in groups of the same size and timing as the active intervention group. The active phase integrated a mixture of aerobic and anaerobic exercises, including drills of "life movements", strength and balance. The primary outcome was: any change in Addenbrooke's Cognitive Examination Revised (ACE-R) and its subscales. RESULTS: At the end of the trial, 52 people completed the active intervention, and 53 people completed the control condition. People in the active intervention improved on the ACE-R (ANOVA: F(1;102)=4.32, p=0.040), and also showed better performances on the memory (F(1;102)=5.40 p=0.022) and visual-space skills subscales of the ACE-R (F(1;102)=4.09 p=0.046). CONCLUSION: : NCT03858114.
