t-and-f: Negative splits in 4400?

2004-03-22 Thread Ruben Romero
Hi  I know there is a well known recomendation to aim to run the first
200 meters 1s-3s faster than the sencond ones in a 400 meters sprint.
Im sure you all are familiar with the negative splits tactic that is
widely used in longer distances, which is based in delaying the the fatigue
in the first half to produce faster golbal times in a raceis there any
chance that this could be transalated to distances like the 400 m?

Actually, it is not all that common (it happens, but not in a lot of cases)
to see world records set with anything other than a very slight negative
split even in a distance race.

As for the 400, I have wondered myself whether there is a physiological
reason to go out fast, because one might instinctively think otherwise.  I
don't know the answer.  800's are generally run almost the same way.

I meant to say anything more than a slightly negative split, not anything
other than :)

All sprinters decelerate in the last half of their races, some just a lot
more than others. That's why it seems like some are running negative splits
compard to others.

If you break up MJ's 400m into 200m splits, you will find his first 200m 
contributed 49% of his total time, whereas his last 200m contributed 51% to 
his total time of 43.18.  I don't remember his 100m splits off hand.

Re: t-and-f: Negative splits in 4400?

2004-03-22 Thread MOrfuss
To me, who was a mediocre (49 relay leg) but totally enthusiastic and committed 400m 
runner 30 years ago (and a student of training), there is no way the negative-split 
approach would pay off for most 400m runners. If Michael Johnson were to have gone out 
in 22 flat, he would never, not even on his best day, have come home in 21.1. 

It seems that energy conservation over the first 200 is a flawed strategy given that 
the 400 is not an aerobic event. If you look at differentials between the first and 
second 200s in the fastest races of all time, you'd no doubt find that the first half 
is 1.5 - 2.5+ seconds faster than the second. The differential, however, has to be 
diminishing as the 19.32 wall (current WR) for the first 200 is approached. But 
diminishing the delta could not carry through to negative splitting. I can't believe 
it ever would, though a difference that gets increasingly closer to even-pace 
splitting has to be what we'll see in the future. When the world record is 41.0, the 
first 200 will probably be 19.8 to 20 flat and the second 21 flat. The race will 
probably always be run with deceleration marking the last 300 meters. Minimizing tyhe 
deceleration is where the great performances will come from. But a slower first 200 
won't achieve that goal. I don't think...

Hey, what do I know? Would be curious to hear other opinions.

t-and-f: USTCA Athletes of the Week

2004-03-22 Thread Tom Borish
March 23, 2004 -- The United States Track Coaches Association announced that 
Brian Chaput of Pennsylvania and Becky Breisch of Nebraska have been 
selected as the Mondo Athletes of the Week for NCAA Division I track  
field.

The USTCA Athletes of the Week awards are sponsored by Mondo, USA, the 
world's largest supplier of track  field surfaces. Mondo is the official 
provider of all tracks and equipment for the Track and Field Competitions 
for the Athens Olympic Games.

Brian Chaput of Pennsylvania :

Pennsylvania senior Brian Chaput finished first in the javelin at the Quaker 
Invitational in Philadelphia on Saturday with his mark of 250-01 (76.22m). 
Chaput, who currently leads the nation in the event, compiled his 
second-best career performance. His personal best mark of 258-02 (78.69m) 
claimed the 2003 NCAA outdoor javelin title in Sacramento. The defending 
Penn Relays, Heptagonal, IC4A, and East Region champion will next compete at 
the Raleigh Relays on March 26-27 in North Carolina.

Becky Breisch of Nebraska :

Nebraska junior Becky Breisch won her first outdoor events of the season to 
lead the Husker track and field team Saturday at the College Station Relays 
hosted by Texas AM. Breisch claimed the discus with her throw of 191-06 
(58.36m) and shot put with her mark of 56-03.75 (17.16m). Both marks 
currently lead the nation in each event. The 2003 Mondo Midwest Regional 
Co-Athlete of the Year is the defending NCAA outdoor champion in the shot 
put as well. Breisch and the Huskers will compete in the Jim Click Shootout 
in Tucson, Arizona from March 25-27.
