Short Bursts of Faster Exercise Beat Steady Cardio for Aging Brains in Rats
This study hints that varying exercise intensity may support aging brains, though it was only tested in rats.
In aged male rats, both steady cardio and interval training helped with learning and memory. But the interval style, mixing slower and faster bouts, showed bigger gains in memory and brain chemistry. The interval group had higher BDNF, a protein tied to brain health, plus more anti-inflammatory and antioxidant markers.
