Overview

Randomized controlled trial shows improvements in cognitive functions and brain connectivity in active older adults, suggesting benefits from online interventions.

Key Points

  • The intervention did not significantly impact visual processing speed but enhanced inhibition and visual memory in the physical activity group.
  • Increased resting-state brain connectivity was observed between attention networks post-intervention, indicating potential cognitive benefits.
  • The study involved 92 healthy older adults, who were randomly assigned to either a physical activity or control group over eight weeks.
  • Online delivery of physical activity training presents advantages such as accessibility and reduced social interaction, offering scalable options for broader implementation.
