High-intensity intermittent training improves spatial memory in rats

Despite lower exercise volume, HIIT was as effective as endurance running for improving exercise capacity and spatial memory. Researchers found that activity-specific physiological adaptations in the muscles and increased signaling and neurogenesis in the hippocampus underlie these improvements. Findings also suggested that benefits can potentially be optimized by tailoring exercise time and intensity.
