2Strength Training May Reshape Brain Markers in Older Adults With Early Alzheimer's Signs
A 24-week strength training program altered Alzheimer's-related brain signatures in cognitively healthy older adults. The effect was strongest in participants who already had amyloid buildup in their brains. Those reductions in brain thickness markers were linked to better executive function, suggesting the changes were adaptive rather than harmful. This was a small trial of 90 people around age 72, so the results need replication.
Why Even One Workout Sharpens Your Thinking, According to Research
A single session of moderate to vigorous exercise reliably boosts executive function, processing speed, and working memory in adults. Cardio led the pack, but resistance training also improved executive function in many trials. The brain benefits seem tied to short-term spikes in BDNF, lactate, and prefrontal brain activity. So even one workout appears to give your brain a temporary lift.
