(Health-NewsWire.Net, November 16, 2015 ) Salt Lake City, UT -- Age weakens the brain's connections, however a new research study found that physical fitness boosts long-term brain function.
The University of Illinois at Urbana-Champaign studied age-related differences in the brains of older adults and found they were different, based on levels of aerobic endurance.
What they realized is higher levels of fitness showed evidence of stronger brain connections in later years. However, it could not prove an absolute cause-and-effect relationship.
Arthur Kramer, director of the Beckman Institute, stated the following in his university news release: "Our study provides the strongest evidence to date that fitness in an older adult population can have substantial benefits to brain health in terms of the functional connections of different regions of the brain."
Younger and older adults took part in the study. With the use of functional MRI brain scans, researchers examined how strong connections in various areas of the participants' brains were when they were awake and alert, but not doing any particular task.
It's not surprising the adults who were younger had strong brain connections versus those older. However, with the older group, a relationship was found linking fitness levels and brain connection strength.
NeuroImage published the study results online recently. The leader of the study, who at the time was a postdoctoral researcher at the University of Illinois, shared "An encouraging pattern in the data from our study and others is that the benefits of fitness seem to occur within the low-to-moderate range of endurance, suggesting that the benefits of fitness for the brain may not depend on being extremely fit."
