Key Takeaways
- Research suggests that a regular exercise program may help slow biological aging and support cognitive health in breast cancer survivors.
- Participants in a remotely delivered exercise trial showed greater improvements in attention and memory compared to those in a general wellness group.
- DNA analyses revealed that biological aging progressed at a slower rate among participants who engaged in physical activity.
- Researchers emphasize that larger studies are needed to determine the exact amount of activity required and who benefits most.
What the Source Says
Studies published in the Journal of the National Cancer Institute evaluated how physical activity influences cognitive function and biological aging among breast cancer survivors. The primary trial included 253 participants who had completed active cancer treatment, reported low levels of physical activity, and experienced cognitive difficulties. Participants were randomly divided into two groups for a 12-month program. One group participated in a remote exercise intervention using wearable activity trackers and coaching to reach 150 minutes of weekly moderate-to-vigorous physical activity. The second group received support through a standard health wellness program without exercise guidance.
The research team found that the exercise group demonstrated higher gains in attention at six and twelve months, as well as greater memory improvements at six months, compared to the wellness group. While both groups experienced overall progress across various cognitive measures, changes in processing speed, self-reported cognition, and executive function did not differ significantly between the groups.
A secondary study led by researchers at the University of California San Diego analyzed blood samples from 124 trial participants using epigenetic clocks to evaluate biological age. The investigators observed that epigenetic aging was slower in the exercise group compared to the wellness group. The findings also indicated that faster biological aging was linked to greater cognitive decline.
Practical Notes
While these initial results are promising, the study authors note that larger trials are necessary to confirm how physical activity protects brain health and influences biological age. Future research aims to clarify the specific biological mechanisms involved, the precise amounts of activity needed, and which individuals stand to benefit the most.
Please talk to your doctor before beginning a new physical activity routine or making changes to your post-treatment care plan.
