Aerobic fitness may be a teller of some brain health, study suggests
Look at a group of kids, and you're going to see many different shapes and sizes.
A recent study from Northeastern University indicates that aerobic fitness and body composition independently contribute to inhibitory control in preadolescent children. Greater aerobic fitness was linked to better inhibitory control, meaning children with higher fitness levels were more accurate in tests requiring them to suppress responses or ignore distractions.
Body fat, however, was associated with more impulsive responses but did not necessarily improve accuracy. The study used dual-energy X-ray absorptiometry (DEXA) scans to measure body composition, a more precise method than the typical body mass index, allowing researchers to isolate the effects of fat and lean tissue.
