Description
Asta Håberg and three co-authors report an unwelcome long-term effect of intense interval training on the aging brain. Their report appeared in twenty twenty-three. It follows the Generation 100 trial, a five-year exercise study in older Norwegians.
Participants trained twice a week at high intensity or moderate pace, or followed national activity advice. Brain scans during the trial showed the high-intensity group losing hippocampus tissue faster than controls. Four years after the program ended, seventy-three participants returned for fresh scans. The faster shrinkage in the intense group was still visible. Fitness measures and self-reported exercise did not explain the gap. The authors flag a paradox: the hardest training helped the body yet taxed a memory hub.
