 Posted: Mon May 17, 2004 2:35 am Post subject: Red and white muscles |
 |
|
I red the difference between red (endurance) and white (sprint) muscles and wonder what happens with the whites during a 10 k race, are they awaiting eagerly the last 200 m sprint and "sleep" the other time. I tend to believe this, because if everything hurts and burns at the end of a race I am still able to accelerate and run very fast (from my perspective) 200 m. It's as this guys were not yet involved in the race.
Does this on the other hand mean, if you have too many of them, you never become a good long disctance runner?

I don't think it works that way. With energy systems, you burn up the fast burning stuff based on duration, not intensity (possibly some of both). My guess would be muscle fibers work similarly. Try running till you puke, then kick it in and see how those fast twitch fibers respond. 
If you're always finishing fast, it probably means you aren't running hard enough up to that point, which distorts the fast/slow twitch conclusion.

Oops  I thought of a genetic gift, instead I am a lazy runner  |

I'll do, I will become a hardcore runner.
I suspected it already a while ago, that we are not fond of running, we are sado-masochists  |

And remember, never take Dan's advice without medical supervision.

Do you know what a doctor would say to me, - you should jog with a heart rate of 130, 3 times a week 30 minutes is perfect. Granted you don't die of a heart attack, but of boredom!
Now back to serious, if you say I don't run intensive enough during the race, how can you find this speed?
When I run, I am in the comfort zone near to where it becomes unpleasent, there I am absolutely sure to finish the race.
Taking your advice it means I must cross the border to "uncomfortable", don't I?

Some people have an innate sense of how hard to push, but most of us mere mortals learn it by trial and error. Since you tend to finish quite strong, steadily up the intensity earlier in the race to the point where you're just barely maintaining at the finish. That's about your proper level. Once you get used to that, you'll be able to hold that pace and still mount some semblance of a kick.

Peter, You might want to try 1 kilometer repeats. Those will help you get used to running a faster pace for longer distances.

Thanks Dan, that makes sense, I'll try it!
Micah: 1K repeats is our usual training. It really helps to improve the speed in general. But I think it's more a mental issue, if I understand Dan's point correctly, it's squeezing out the chicken ... |

Another question concerning muscles: do we use different muscles for cycling as for running?
As I celebrated this year a special birthday, my family bought me a racing bike - a childhood dream, which I forgot  .
I expected that I can transfer most of the my running power into cycling speed, but this is not the case. Looking at the size of my legs I thought there is hardly a muscle which is not fully developed. Or is it the different way they are used?
I will try a short distance triathlon in July (although my swimming is disastrous)!
Peter
PS: cycling on a racing bike is pretty cool, - but running is still my first choice! |

Muscles are muscles, you just need to condition them to the specific activity.
