Theoretically, I could do a proper warm-up before a 2K trial, but I don't have it in me at the moment (and I wouldn't have the benefit of race-induced adrenaline). So....
Does anyone have any anecdotal thoughts about this?
Cheers!
Very well put. I have an image in my head that shows the same thing. It's not what I had found a year ago, but it supports the idea that there is a 'lag' in the time between peak oxygen usage by muscles and the demand you place on your muscles. By getting your HR up some before a test piece, you quickly hit that point that your body is using its oxygen to generate ATP, instead of needing to run through some glycolysis and creatine phosphorylation.ArmandoChavezUNC wrote:I am no expert in the field, but IMO warming-up does make a difference (a positive one at that) in your performance on a 2k. It probably won't be that big of a difference, probably less than 3/4 seconds, but it's a difference nonetheless.
If you jump as high as you can from standing, then do some squats, then jump again --> you will notice a huge difference in the height you can jump. That's due to more muscle units being recruited. It doesn't quiet work the same when doing something like a 2k but you get the idea. As the temperature of your muscles increases they become more efficient and more units can be recruited. If you start a 2k with no warm-up, your muscles will spend the first few hundred meters trying to get warm, and you will most likely get tired way quicker than you would otherwise (you would also risk injury).
Yeah, I get that a lot!laur wrote:you were mentally weaker
I have found that to be the normal thing for me. That is to find the second of a set of intervals to be faster and easier than the first, even with a moderate warm up beforehand. Even the third interval is as good or better than the first and once in a while better than the second. It varies with the kind of interval and rest period used in the set.aharmer wrote:I don't know the physiology well, but it definitely makes a difference for me. Tonight I warmed up for 1500m but it was all slow and easy strokes. My first 1500m interval was pretty hard. The second one was far easier. On that first one I was in oxygen debt after about 300 meters and wondering how in the world I was going to finish the first piece, let alone 4 more after that.
I think a nice long easy warmup, followed by a couple good race pace bursts of 300m+ about 5 minutes before the race. That said, I'm pretty new so I haven't perfected prerace preparation yet.
