High-Intensity Exercise May Protect Against Cocaine Addiction

A new study shows that high-intensity interval training (HIIT) is more effective than moderate exercise at protecting adolescent lab animals from cocaine use. Animals exposed to HIIT developed a preference for non-drug environments and an aversion to cocaine, linked to increases in ΔFosB, a molecular switch involved in addiction.

Single Bouts of HIIT Exercise Boost Brain Power

New research finds that even single bouts of intense exercise can improve cognitive performance in young adults, particularly in memory, attention, and executive functioning. High-intensity interval training (HIIT) and cycling yielded the most substantial cognitive benefits, especially when lasting under 30 minutes. While the cognitive boost was modest, it suggests that brief, vigorous exercise may have a more immediate effect on brain function than previously thought.
