Diet-restricted mice perform better in sports

Calorie-restricted mice perform better in tasks that involve reaction,
speed and have better endurance. The study corroborates on the earlier
finding that the combination of caloric restriction and free exercise
acts synergistically to increase muscle endurance and strength.

From the study:
"In response to assigned tasks, the diet-restricted mice performed better in
all activities: they climbed out of obstacles faster, freed themselves
sooner from restraint by gummed tape, hung from a bar longer, and better
resisted slipping down a slope."

Most of the tests favor a lower body weight and/or smaller size, so I don't
think you can say calorie restriction can increase muscle strength.

Relative strength is increased, judging by the results. It would be hard
to extrapolate to human success in sports.

First one is this guy - http://tinyurl.com/2qw6n and the
other one is me :)

See if helps as you're sliding under that out-of-control taxi that's
hurtling at you at 85 mph.

I remember two individuals posting to these groups who claimed ability
to do multiple muscle-ups. Both are on some sort of dietary
restriction. First one is this guy - http://tinyurl.com/2qw6n and the

This topic is very much of interest to me. I train for health and
longjevity, not a huge body. I'm not really small at 5'10" and 189, 10% BF.
But I like my current size and don't have a desire to get any bigger. I'm
also 48. So I'm setting up to jump into my 50s. I'm thinking lean and on
the small side yet strong is the way to go. I do know that I feel better
when I'm lean. Also, from a MA background, I like the quickness I get from
being this way. IOW, I don't see myself jumping into PL anytime soon.

Please post more on this subject as it comes up in your reading. I find it
interesting.

It can be dangerous to extrapolare to humans from mice...

And even more dangerous not to.
We wouldn't have biology or medicine to speak of.


I volunteer the members of rec.running and alt.support.diet to take the
place of mice, rats, pigs, beagles and chimps in all experiments.

PETA would be happy with that.

Could it be that the calorie restriction is stimulating adrenalin production
which in turn has some useful side-effects on reaction times etc, rather
than a real increase in muscle strength?


Why would you assume that?

FWIW, I was able to find one study which indicated that epinephrine
was catecholamine which changed *least* during calorie restriction and
refeeding.

Not an assumption, more an idea looking for contradiction or confirmation,
hence the post formulated as a question.

It was just a cross between my vague recollection of something I'd read
about the role of adrenalin in both fat metabolism and reaction times (maybe
my last remaining, shriveled neuron is playing up on me :-) and a personal
experience of a keen sharpness during the second half of the Sand Marathon
(one week running in the Sahara desert, av 40km / day, with a 8kg backpack,
3kg of water and ~2400 calories/day)

Thanks for the help. I will go with the Cell-Tech.
