1. In a recent study, the role of exercise was studied to see if it resulted in halting the cognitive decline after one year of regular exercises. Investigators enrolled 296 sedentary men and women with MCI (mean age, about 75 years).
2. All were randomly allocated to either an aerobic exercise group (maintaining a #heart rate at about 70% to 85%) or a stretching and balance group (maintaining heart rate < 35%).
3. Both groups exercised four times a week for about 30 to 40 minutes. In the first 12 months they were supervised by a #Trainer at the YMCA and then they exercised independently for the final 6 months.
4. Participants were assessed at baseline and every 6 months. The primary endpoint was change from baseline on the ADAS-Cog-Exec, a validated measure of global cognitive function, at the end of the 12 months of supervised exercise.
5. Over the first 12 months, neither the aerobic group nor the stretch/balance group showed a decline on the ADAS-Cog-Exec. This meant that cognitive function remained stable during this period.
FINAL: Regular exercises (120-150 min per week) under guidance of a trainer and with some social interaction prevents cognitive decline in sedentary older adults. (Source: Megan Brooks; Medscape News Aug 2022)
