Weight/BMI

[fell]

track running is a tad boring in my books

my times
100 - 00.11.50
5000 - 17.29.00
and did a 10km+ streetO at the start of the year in 36min.
and that's all I know. I should get a watch.

I know Carsten Jorgensson's pb 10km is 27:54

what is a good indicator for orienteering fitness?

and is the rumour true that if you drop 10% of your body weight you can run 30% faster? And does this only apply to fat people?
(have I brought this up already?)

[Jene]

i was told this......tho i was told only 20% but hey....im finding it impossible to do........so i gave up...

not what you were really after, but could be of interest to some. UK athletics run standards scheme for juniors from 1-4. The U 17 mens' ones are below; I have the others if you want. (they're probably on UK athletics website too) If you could reach any of these AND orienteer well you'd be force to be reckoned with in orienteering (and track) but, of course, you can certainly do well in orienteering without amazing track times. To get these times you would need to get out into club level track racing (probably). Most UK young athletes club races local to me are won in a level 2 or level 3 time.
U17 men 800m 1.59; 2.02; 2.05; 2.12
1500m 4.10; 4.16; 4.24; 4.34
3000m 9.00; 9.20; 9.40; 10.10
1500m steeplechase 4.30; 4.40; 4.52; 5.10
I would say that the fittest under 17s in my club have done (or could do) level 3 or even 2 at at least one of these distances (but may not be the best orienteers).

[Mrs H.]

Haven't you two been paying attention. The answer is yes you propbably will run faster - for a while - then you wont. You will also be a cripple by the time you are my age and seriously damage your fertility before that. So the message is this - if you want to win a few races in the next couple of years go ahead and try it - if you want to lead a long and healthy life, raise a family and do loads of other interesting things - including winning a few races over the next 60 years - THEN DON'T Is that clear enough for you?

[Rockaldo]

The answer is yes

The answer to what?

[Kitch]

the answer to the losing weeight to run faster question.


I've said this before, I'll say it again.

British International Orienteer lost too much weight in her early twenties. Loves running - but can't, because she has been injured ever since (10 years).
Unhappy.
So, as Mrs H so succinctly puts it DON'T

[ifititches]

for Rockaldo, since previous discussion was before his time/memory! Hope this works, if not go back to skinny runners discussion topic started in July 2004!

[Rockaldo]

Oh right. Yeh hadn't joined nopespot then. I agree that you shouldn't try to loose weight to go faster.

[pyrat]

despite these dangers of being too thin and destroying your body, there surely must be an optimum weight for yourself where the working muscles can get supplied with more oxygen and there is little surplus fat.

Is there anyway to work out what your optimum weight should be? We are not talking national averages here as runners are not average. Based on height? What about bone mass does that vary? I reckon I am about 5ft 10ins and weigh in at about 60-65kgs. Is this acceptable, or should I eat more curries / go on the atkins diet?

-p

[Mrs H]

Sounds incredibly light to me - but then young Neville is nearly 6ft now and weighs about 63kgs and I feel like a little robin shovelling food down his cuckoo beak non-stop so i suppose the question must be are you eating enough (IE as much as you could possibly want,) do you get ill easily, pick up injuries etc etc. I really can't see it's possibly to come up with a general figure - look at Mr H. he feels weak if he drops below 13 st as he is literally built like the proverbial - but he does physical work and needs to be strong.

[J.Tullster]

Personaly, I think if you're doing lot's of training and eating a good diet, I wouldn't give a toss about your weight as long as you are running well. Weight's a very individual thing. I weigh just under 70kgs, which ibout 10kg heavier than the likes of Scotia (he is a weed mind ) but I don't really pay attention to it.

[Mrs H]

Oh and another thing is do you feel the cold more than others. For girls it's pretty obvious, have your periods stopped, are you growing more body hair, do you still have a bum? ( it doesn't have to be one you can park your bike in and rest your pint on - but it should still be there all the same!)

[Jene]

well im 5'4....n bout 46 / 47 kg's....think i'd be able to run faster if i was bout 43 / 44 but not much less....but cant seem to lose it

do you still have a bum?

hmmmmm
where's the divide.....

[harry]

i reckon for girls it's ok to go down to about a BMI of 18 and it be safe.
it's weight in kilos divided by height in metres squared so mine is 55/1.67 x 1.67 = 19.7.
"desirable" is considered to be 20-25 and above that is overweight, above 30 obese. but in female endurance athletes 18-20 is considered ok it's when you get down to 16 or 17 you start to get the problems mrs.h discussed.

so i could probably do with eating less curries but i reckon a bit extra weight/and curries helps prevent the illnesses you get from the immunosuppression associated with training hard so i'll drop it in the spring after the bulk training period and before the season.
no more bad food after march -and more melons (or in some sense less)!!
