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

Re: t-and-f: Negative splits in 4400?
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. - Ed - Original Message - From: Ruben Romero [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Sunday, March 21, 2004 3:29 PM Subject: t-and-f: Negative splits in 4400?

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.

Actually, I'd be shocked if his last 200 WAS faster for his record. More than shocked - shaken to the core :) - Ed - Original Message - From: Andrew Lilly [EMAIL PROTECTED] To: edndana [EMAIL PROTECTED]; Athletics [EMAIL PROTECTED] Sent: Monday, March 22, 2004 5:08 PM Subject: Re: Re: t-and-f: Negative splits in 4400? not truly a negative split, but rather the top guys are going to fly that last 200 with a running start, even given their level of fatigue i'd be surprised if MJ's last 200 wasn't faster than his first 200 for his record From: edndana [EMAIL PROTECTED] Date: 2004/03/22 Mon PM 04:39:53 EST To: \Athletics\ [EMAIL PROTECTED] Subject: Re: t-and-f: Negative splits in 4400?

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. Jared _ Tired of spam?

Re: t-and-f: Negative splits in 4400?
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. Mitch Orfuss 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.

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.
