Summary

Story summary

A study published in Aging and Disease shows high-intensity training (HIT) improves hippocampal function in adults 65-85; low- and medium-intensity regimens do not.
The six-month study compared LIT, MIT, and HIT, with 72 sessions completed.
Three HIT sessions per week yielded lasting cognitive benefits, potentially up to five years.
HIT links to increased brain-derived neurotrophic factor (BDNF), supporting brain connectivity.
