Scientists uncover how different workouts boost brain power

This study looked at how different exercise intensities affect brain function and certain chemicals in the body, like irisin and lactate. Twelve healthy young adults aged 18-25 completed three types of exercise: short high-intensity intervals, long high-intensity intervals, and low-intensity continuous training. Researchers measured blood levels of irisin and lactate, and tested thinking skills using a trail-making test before and after each session. The goal was to understand the link between exercise intensity, brain performance, and these neurochemicals.
