Talk:Anaerobic exercise

The direction I was thinking of taking it was talking about why people do anaerobic exercise, since Anaerobic_metabolism has the chemistry of it covered. Not sure how to best handle the talking about it in that way yet. If anyone has any ideas go for it.

Also I think in general the whole exercise/fitness part of wikipedia needs a lot of work. For example Weight_loss just redirects to dieting [not any more - user], when in reality exercising is much more effective than dieting to lose weight, and weight loss programs that do not included exercise suck and usually fail(IMHO). Perhpas because we have good articles on aerobic/anerobic metabolism the Anaerobic/Aerobic exercise pages should primarily be a collection of links to exercises of their type, with a few words about the benefits and comparison of anaerobic and aerobic exercise.

In university level textbooks the terms aerobic/anerobic have generally been superceeded by more accurate terms. there are three energy systems the muscles use:

The high intensity/short duration system: known as phospagen/high energy phosphate or ATP/CP system. The intermediate system: known as (oxygen independent or non-oxidative) glycolytic system. the long-term system: known as (oxygen dependent or oxidative) system.

furthermore there is an overlap between the energy systems for any particular exercise: for example Fox E & Matthews (1974) shows that even a sport as "anaerobic" as weightlifting draws 95% of energy from the short term system and 5% from the intermediate system.

most of this can be checked against "Supertraining" 6th edition, Dr Mel Siff & Dr Verkhoshansky

This article is somewhat contradictory to the article on Lactate or lactic acid. Seeing as they are not the same I find it inaccurate that they are treated as such in this article. The debate over lactate may be active but if so then it shouldn't be held as fact.

glycogen and switch to aerobic metabolism

the article states that running out of glycogen in muscles is what switches one to aerobic metabolism. i thought this was what happens when a marathoner "hits the wall", which is long after he turned to aerobic metabolism. can anyone clarify this, or fix it if need be.

The difference here is muscle glycogen vs liver glycogen. Hitting the wall is usuallu associated with running out of liver glycogen. Pasta loading is all about 'filling up' the liver with glycogen. David D. (Talk) 04:02, 14 June 2006 (UTC)[reply]

removed controversial study

I removed the section on the controversial study on lactic acid.

It was long thought that lactic acid, the end-product of anaerobic metabolism, causes muscle fatigue and must be burned up by the body during a recovery period before another anaerobic bout of exercise can be attempted. However, scientists now accept the view that lactic acid may actually facilitate further exercise, and is itself a valuable fuel used by mitochondria in aerobic metabolism^{[citation needed]}. The recovery period also allows the muscles to use oxygen to replenish the energy used during the high intensity exercise.

This could be expanded in its own section but is not really introduction material. David D. (Talk) 04:02, 14 June 2006 (UTC)[reply]

Discussion of different forms of anaerobic metabolism absent in this article!!!

Check out http://www.brianmac.demon.co.uk/energy.htm in which it explains the ATP form of anaerobic metabolism and the 'Lactic acid form'. p WHy does this article not discuss the differences??? Possibly one of the worst content articles I've come across. Can somebody who can do it properly take in this information and improve this article??? —The preceding unsigned comment was added by 210.49.183.79 (talk • contribs).

It is there:

"Anaerobic exercise begins with muscles utilizing stored creatine phosphate to generate the ATP that produces muscle contraction. After several seconds, further ATP energy is made available to muscles by metabolizing muscle glycogen into pyruvate through glycolysis, as it normally does through the aerobic cycle. What differs is that pyruvate, rather than be broken down through the slower but more energy efficient aerobic process, is fermented to lactic acid."

I would suggest you rewrite that paragraph so it is more like the form you were expecting. Are ATP form and lactice acid form recognised terminology? David D. (Talk) 19:44, 27 January 2007 (UTC)[reply]

center around?

Why not write center on? How can you center around something? (In the first sentence of the article.)62.142.45.245 23:52, 6 March 2007 (UTC)[reply]

mM/L?

Am I missing something here? Molarity is a measure of concentration, and so M/L doesn't make much sense to me. Perhaps it should be mmol/L? Gaspard 15:50, 28 June 2007 (UTC)[reply]

Suggestion?

I came to this page to find out what Anaerobic Exercise was, and instead found information on what's chemically going on and what chemically constitutes it. I also found out what exercises are aerobic. I still don't know what exercises are anaerobic. Perhaps list and explain examples? --76.214.201.26 06:35, 23 September 2007 (UTC)[reply]

Agreed. I looked up this page hoping to find examples of anaerobic exercises and learn what the practical differences are between an aerobic and anaerobic exercises. 71.193.188.131 (talk) 17:24, 3 April 2009 (UTC)[reply]

Yeah; it's bizarre that the article on anaerobic exercise doesn't list a single anaerobic exercise. 98.217.79.216 (talk) 17:08, 11 December 2010 (UTC)[reply]

Question about creatine-energy rest period

If creatine energy stops after 30 seconds, how long must a person rest before he will be able to use the creatine again (instead of using the second inferior energy source called 'glycolisis'? —Preceding unsigned comment added by 216.73.210.68 (talk) 02:38, 8 December 2008 (UTC)[reply]

Heart Rate diagram

I have pointed out an error in the heart rate diagram in the Talk:Aerobic exercise#Error in diagram discussion. Best contribute there if you have anything to add.
