We’ve known for more than 20 years that exercise positively
alters brain chemistry, but some recent work on different types of exercise has
me really excited. The New York Times
reported on two studies that explored the relationship between exercise and
memory. These studies compared the
impact of weight training vs. aerobic exercise on cognitive functioning in both
animals and humans and the results are enlightening. Aerobic exercise increased proteins in the
brain that support existing neurons and help new neurons develop. Weight training increased proteins that
encourage cell-division in newly formed neurons. Both types of exercises contributed to
improvements on cognitive tests. Thus
the combination is like a double shot of awesome for the brain!
We already know that a varied approach in exercise is
healthy in other ways as well.
Weight-bearing exercises including weight-training and running help to
prevent physical ailments such as osteoporosis and heart disease. And surely if some variety is helpful, more
variety might very well add to the awesomeness of this program. So adding regular sessions of cycling and
swimming, both easier on the joints, creates a truly comprehensive exercise
program. I love that triathlon training
is an excellent long-term program for maintaining healthy hearts, bones, and
brains.
The trifecta of triathlon giving us a trifecta of health
benefits. Genius.
