Aerobic Exercise (AE) included walk briskly, increasing intensity and duration progressively. The first week they had to walk 30 min per day, 3 days per week, up to 9-10 on the Borg Rating of Perceived Exertion Scale (BRPES; Borg, 1982) perceived as light intensity; during the second week, the duration was increased to 45 min and the intensity 9-10 and frequency (3 days per week) were maintained; the following 10 weeks they maintained the duration (45 min) and frequency (3 days per week) and increased the intensity up to 12-14 on BRPES perceived as moderate-high effort.

Computerized Cognitive Training (CCT) included a multidomain computer-based cognitive training using the brainHQ software in sessions of 45 min, 3 days per week for 12 weeks. Cognitive tasks targeted attention, recognition, colour and shape, identification, calculation, visual perception, visual spatial processing, memory, and executive function).

Participants were exposed to balancing, coordination, stretching, and core exercises. Additionally, they attended brain health lectures to provide a comparative non-interactive cognitive engagement. Both the exercises and lectures were scheduled similar to the intervention group over 12 weeks.

A commonly used test to assess different cognitive domains, including short-term memory recall, visuospatial abilities, executive functions, attention, concentration, and working memory. MoCA scores range between 0 and 30 where the highest score is considered to be normal.

This index was used to measure an individual's capacity to perform ten activities of daily living, reflecting their functional independence. Total possible scores range from 0 - 20, with lower scores indicating increased disability.

A generic measure utilized to assess the health-related quality of life, covering both physical and mental health dimensions. The summary scores range from a minimum of 0 to a maximum of 100. Higher the SF-12 scores, indicates the higher (better) quality of life.
