Abstract

Background/objectives: Individuals with subjective cognitive decline (SCD) have an increased risk of developing dementia, while non-pharmacological multicomponent lifestyle interventions are recommended for prevention/management. The Greek Interventional Geriatric Initiative to Prevent Cognitive Impairment and Disability (GINGER) is such a multicomponent approach, encompassing simultaneous interventions (cognitive training, depression and sleep management, etc.). Exercise/Physical activity (PA) is suggested as one such intervention. This study (i) presents the exercise protocol developed for GINGER and (ii) explores its feasibility (acceptability, applicability, adherence, users' satisfaction and reliability).

Methods: Exercise/PA protocol development, targeting SCD individuals aged > 55 years, utilized relevant guidelines/literature followed by focus group involving exercise specialists. Data were synthesized through consensus to design optimal exercise interventions prescribed on participant's physical capacity (heart rate, exertion, etc.), comprising 6-month combined aerobic, strengthening, balance and dual-task exercises, delivered 3 times/weekly in two group-based supervised sessions (in-person and online) and one home-based session. Physical outcomes include balance, aerobic capacity [2-Minute Walk Test (2 MWT), IPAQ-7], strength [Hand Grip Strength (HGS), Sit-to-Stand], fear of falling. Eligibility for entering intervention is low IPAQ-7, 2 MWT or HGS scoring. Feasibility was explored with adherence (exercise diaries and Exercise Adherence Rating Scale) and satisfaction (Patient Satisfaction Questionnaire) Results: Intervention was easily delivered with good reliability across testers' assessments on 13 SCD participants (ICCs = 0.62-0.99), and improved physical outcomes, whereas users' adherence and satisfaction scored highly.

Conclusions: The exercise protocol for SCD was feasible, acceptable, applicable, reliable, demonstrating adherence and satisfaction, while improving physical parameters. It is thus integrated in the GINGER study, where multiple simultaneous interventions will take place to prevent/enhance cognitive function.
