This observational, cross-sectional study aims to comparatively investigate the effects of outdoor versus indoor exercise environments on overall cognitive performance and its specific sub-domains (attention, memory, and executive functions) in older adults with similar physical capacities. Utilizing a 2 (Exercise Environment: Outdoor vs. Indoor) x 2 (Center: Köyceğiz vs. Erzurum Tazelenme University) factorial design, a sample of 100-120 participants aged 60 and over will be recruited via purposive sampling. To ensure sample homogeneity regarding functional capacity, participants will undergo pre-screening with the 6-Minute Walk Test (6MWT) and the 30-Second Chair Stand Test, while individuals with advanced neurological disorders or severe physical impairments will be excluded. Data will be collected through a Sociodemographic Information Form, the Physical Activity Scale for the Elderly (PASE) to monitor baseline activity parameters, and the Addenbrooke's Cognitive Examination (ACE-III) Turkish Version A to assess cognitive outcomes. Ultimately, this study aims to elucidate the potential predictive role of the exercise environment on cognitive health in late life and explore whether the cognitive benefits of physical activity vary interactively across different geographic centers.

Overall Cognitive Performance and Sub-domains via ACE-III
Cognitive functions will be assessed using the Addenbrooke's Cognitive Examination-III (ACE-III) Turkish Version A. The test comprehensively evaluates five cognitive domains: attention, memory, verbal fluency, language, and visuospatial skills. Total scores range from 0 to 100, and sub-domain scores range as follows: Attention (0-18), Memory (0-26), Verbal Fluency (0-14), Language (0-26), and Visuospatial (0-16). Higher total and sub-domain scores indicate better cognitive performance and higher cognitive reserve.

This cohort consists of older adults aged 60 and over, enrolled in Tazelenme University, who regularly participate in physical exercises in outdoor environments. Participants in this group maintain similar functional and physical capacities as verified by the 6-Minute Walk Test and the 30-Second Chair Stand Test, and they do not have any advanced neurological or severe physical impairments.

The study population consists of older adults aged 60 and over who are actively enrolled as students at Köyceğiz Tazelenme University and Erzurum Tazelenme University in Türkiye. This population represents a unique cohort of older individuals engaged in lifelong learning and structured active aging programs. To investigate the specific role of the exercise environment on cognitive reserve, the sample will be drawn from this population using purposive sampling, selecting individuals who regularly participate in either structured outdoor or indoor physical activities. The population is structurally characterized by functionally independent older adults who exhibit homogeneous physical baseline capacities-verified via objective clinical performance benchmarks-and are free from advanced neurological or debilitating physical conditions.

Individual participant data (IPD) will not be shared publicly to maintain participant confidentiality and strictly protect personal privacy in accordance with the national Personal Data Protection Law (KVKK) and the institutional ethics committee guidelines. Since the data collected includes comprehensive sociodemographic details and physical/cognitive functional health scores of vulnerable older adults, public sharing of raw individual datasets is restricted by the institutional ethical clearance. However, aggregated statistical results and study outcomes will be fully accessible through peer-reviewed academic publications.
