Michelle Voss of the University at Illinois at Urbana-Champaign and her colleagues recently reviewed data from 111 studies to examine the effects of exercise on participants. The results suggest that workouts, particularly aerobic exercise, may improve memory, attention and decision-making in children, young adults and the elderly.
High-load or high-intensity strength training may also improve memory in older adults. High-intensity training (HIT) is defined by the use of short routines that push a muscle to the point of exhaustion and stop just short of being unable to perform the exercise again, according to hittraining.org.
The researchers, who published their results in the Journal of Applied Physiology, said they aren't sure exactly why exercise seems to have this effect, and more research is needed to find out. If you're building muscle already, or you've been thinking about it, these findings are another reason to start or continue your strength-building exercise.
The research indicated that exercise may boost the repair and growth of brain cells, actually changing brain structure. Next time you gear up for a strength gain workout or some muscle building, remember you might be improving your mind and body at the same time.
