Strength 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.
Resistance Training Plus Amino Acids Beat Either Alone for Muscle in Older Women
In healthy women aged 65 and older, combining resistance exercise with essential amino acid supplements for 12 weeks increased muscle mass more than doing either one alone. The combo group also showed the biggest improvements in fitness tests and the best shift in muscle-related hormones. Inflammatory markers dropped too, with one key marker only declining in the combined group. Each intervention helped on its own, but pairing them produced clearly stronger results.
