Assessing Causality of the Association Between Exercise and Neurocognitive Gains

19. August 2022 aktualisiert von: SH Annabel Chen, PhD, Nanyang Technological University

Brief Summary: The aim of this project is to examine:

  1. The effects of a community based square stepping exercise programme on cognitive and physical functions in older adults.
  2. The effects of a community based square stepping exercise programme on neuroplasticity in older adults.
  3. The effects of a community based square stepping exercise programme on structural and functional brain changes in older adults.
  4. The relationship between exercise-induced changes in neuroplasticity, structural and functional brain activations, and cognitive and physical gains in older adults.

Detaillierte Beschreibung

It is well known regular exercise produces both physical and cognitive benefits. Emerging evidence suggests that physical movements or exercise that have concurrent cognitive demands may have more profound effects on cognitive and brain health outcomes. One training program that incorporates these components is the square stepping exercise (SSE). First demonstrated in Japan, this community-based paradigm has already shown to reduce falls risk and presents as a convenient exercise modality for older adults, that can be conducted in a group setting or even the home. The current project aims to examine the efficacy of this SSE community programme in a Singapore context on cognitive and physical health in older adults. This study also aims to quantify the neural correlates underpinning any observed improvements in cognitive and physical function. Specifically, this project will measure indices of neuroplasticity via structural and functional magnetic resonance imaging, transcranial magnetic stimulation, and electroencephalography.

Sample size estimation: n=80 for behavioural primary outcome measures and n=40 subset of larger sample for neuroimaging and neuroplasticity secondary outcome measures [anticipated].
