Explain this: 58 Degrees and Raining in Eugene and We've Seen 38.17 4x100 CR, 43.61 400m CR, 47.02 400 h CR

It's called the "Hayward Field Magic!"

I'm not sure what you're saying.

The lower barometric pressure is similar in effect to high altitude.

There also may be no wind.

Has NCAA started for-real testing yet? Where they can show up anytime, 24/7?

^ this is why. Golfers are well aware of how low air pressure impacts ball flight (common in the PNW).

Also, ever ride a bike during the moments before a hellacious thunderstorm? You feel like superman.

But this wasn't a thunderstorm. There was torrential rain however after the meet was over.

I'm surprised weldon doesn't remember our dad always talking to us about Mexico City and 1968. Whenever we were playing sports as kids, my dad would try to pump us up if there was a thunderstorm nearby as he said it might mean something magical could happen which is what happened with all of those WR on the day of the LJ in Mexico City.

I think the guy talking about the ions on the air is on to something. I'd like to the actual scientific explanation.

The train was downhill. It's also only 397.890889 meters; I measured it myself.

American college sports is so full of doping it´s not funny.

The OP is either clueless, a troll or a click-baiter, having another post implying there was a lot of rain - "Rai Benjamin 47.02 400m h (#2 ever) in pouring rain. WTF is in the air today?".

Sorry to bring FACTS into this (knowing it's a Trump world and all) but there was a total of less than .1 (one tenth) of an inch of rain during the approximately 150 minutes of the men's finals. There was never "pouring" rain. There was a total of .01 (yes, that is one hundredth) of an inch of rain for the entire hour between 6:54 & 7;53, the 400m hurdles were at 6:57. As others have commented, there was essentially no rain during the 400m hurdles final.

The simple answer to why the great times - great athletes. Anyone paying attention to Norman and Benjamin over the last few years could see their potential. And Houston was loaded in the 100m but the times for the final were ok. It was in the 4x1 relay where their combined speed and great execution (and coaching) made the difference.

As others have commented, the times in the 100m, 200m, 110mHurdles were nothing to get excited about. The weather conditions were hardly perfect. But they certainly weren't that bad.

Also, as stated, if there was indeed a thunderstorm after the meeting, that indicates strongly that the air pressure would have been low.

Storms form in areas of low barometric pressure, and this would have helped sprint times, not hindered them.

And most of these times were set while rain while still pouring down. Every other meet with rain ends up being a dud -- most recently Shanghai DL this year where there was a huge (but slow) upset in the 100m. Why is it so different in Eugene today? Is it the temperature that's the difference?

Surprising that little standing water on the track didnt slow them down at all.... newer tracks do absorb a bit water these days but those were more than just damp patches....

Got lost in the mix of the other thread, but a small amount of water on a track makes that track faster. Water is not compressable, so when it feels in the little micro-gaps on the track the entire track becomes stiffer and thus faster due to better energy transfer.

Yesterday's conditions were ideal and the proof is right in front of us all in the form of the times.

This is how high concentrates of negative ions are produced . Basic science .

Drug testing in college is virtually nonexistent, so there’s that.

With that being said, are the coaches the ones administrating the drugs or athletes do it by themselves?

This is the start of more people being allowed to use drugs - and get away with it - to help cover the E. African debacle that was capped by Kiprop's positive. Oh, not everyone will be allowed to cheat. But sprinters if they're of the proper ilk, athletes from certain third world countries, and of course the E. Africans, will all be allowed to cheat like mad in order to sidetrack people looking into what's up with the E. Africans. They'll have so many top performances over the next two years that all the SJW types will be kooking and cucking about how anyone could ever doubt the superiority of (insert any of the usual suspects here). Meanwhile, athletes who aren't part of the anointed groups will find themselves being tested even more often, with possible attempts at framing. Laugh now, but itz coming, some of it is already here.

Sure it is. Just not a lot, at least not with our current abilities. All matter is compressible (note correct spelling). Learn the term "bulk modulus." In simple terms, it represents how much a liquid or solid can resist pressure compressing it from all directions.

Water is actually much more compressible than steel: liquid water's bulk modulus is 2.2 GPa - what that means is that to shrink water to 99% of its normal volume you would have to apply a pressure of 22 MPa (3,200 lbf/in2). In comparison, steel has a bulk modulus of about 160 GPa - so steel is about 80x times less compressible than water.

At the bottom of the oceans, around 4000m, water is about 1.8% compressed.

When water is compressed it turns to solid, but not ice as we know it; these types not found in your freezer. There's 16 different types of these crystalline phases, based on pressure.

no idea about sprints but I always PR at distance in the rain, keeps the motor from overheating

evaporative cooling of wet skin

Please don't bring the FACTS here. They aren't wanted.

1. Low barometric air pressure

2. Combined with high humidity

3. plus an historically exceptional year of talent concentrated in two teams

4. plus competent coaching

Does anyone really believe that Dennis Mitchell wouldn't have screwed up those relay teams? I got a bridge in Brooklyn I'd like to sell you.

Weather more conducive for distance running rather than 400 meter or sprinting.

excellent, plus a fast track, when a bit wet.

Years ago I heard breaks between rain produce the best results. Plenty of evidence in this thread to support those claims.

Some interesting twitter exchange on the topic:
