Study shows remotely supervised exercise can boost brain health in older adults

As the global population ages, the incidence of mild cognitive impairment (MCI) is on the rise. MCI is a precursor to more severe cognitive decline and dementia, affecting millions of older adults worldwide. With limited treatment options and a growing need for effective interventions, researchers are increasingly turning to exercise as a potential solution.

A new study published in General Psychiatry has found that remotely supervised exercise programs can significantly improve cognitive function in older adults with MCI. The research highlights the potential of home-based exercise interventions in preventing cognitive decline.

In the study, 108 participants with MCI were involved and were randomly assigned to one of three groups: aerobic exercise (AE), resistance exercise (RE), or a control group. The interventions were delivered remotely, allowing participants to exercise at home under supervised conditions.

The study found that both remotely supervised AE and RE programs were feasible and effective in improving cognitive function. Specifically, the AE group showed significant improvements in global cognition and the RE group demonstrated notable improvements in executive function.

Additionally, the study found that the AE group increased their levels of moderate-to-high-intensity aerobic activities, while the RE group improved their resistance activity scores. Physical performance and muscle strength also showed positive trends in the RE group.

The findings suggest that remotely supervised exercise programs could be a valuable tool in managing and preventing cognitive decline in older adults with MCI. Dr. Qiaoqin Wan, one of the study's corresponding authors, said: "Exercise is not just good for the body; it's also good for the brain. These remotely supervised exercise programs make it possible for older adults to stay active and engaged, even when they face challenges in attending in-person classes."
