Here's a bit of interesting news from today's edition of "Sham
vs. Wham: The Health Insider" (Google for original text):
As it turns out, a bowlful of cereal and a bit of nonfat milk
may work just as effectively as specialized sports drinks in
boosting recovery after exercise. Researchers at the 54th
Annual Meeting of the American College of Sports Medicine
(ACSM) told attendees at this meeting that the benefits they
discovered have been linked to the protein and carbohydrate
content of the whole-wheat cereal used in the trials, which
may aid the rebuilding of damaged tissue after exercise.
Lead researcher Lynne Kammer from the University of Texas at
Austin says "We were surprised that blood lactate was lower
after cereal, possibly due to glycogen storage," she said. "In
addition, the muscle was ready to store additional glycogen
after the cereal-and-milk regimen, even after glycogen had
already been synthesized."
There is a huge convenience factor associated with sports
drinks, so it may not be possible to market a whole-wheat
cereal and milk package for this market. But, it is really
interesting to many athletes that there is no real advantage
to the drink other than the convenience.
"We wanted to look at a realistic exercise scenario and
test the effectiveness of whole foods that might be
acceptable for muscle recovery," said Kammer. Here are the
facts of the trial:
** The researchers recruited 12 cyclists (eight men) and
asked them to fast for 12 hours prior to a two-hour cycling
exercise. After working on the bicycle ergometer, the
volunteers were given either a whole-wheat flake cereal with
skimmed milk or a sports drink containing carbohydrate.
Both interventions were found to raise blood glucose and
insulin levels, but during the recovery phase, cereal
raised insulin significantly higher and blunted the rise
in blood lactate compared with sports drink, Kammer told
attendees. The cereal group also showed a significant
advantage in protein synthesis and additional glycogen
storage potential. **
No mention was made of the specific cereal, but it's
interesting to note that this research was sponsored by a
grant from Wheaties and the General Mills Bell Institute of
Health and Nutrition.
