Energy System In Track and Field

Firstly, I won’t go into very detail as I know everyone out there are prefer the simplest way to gain information. Thus I'll try to explain as simple as possible so that people at all levels will get the points.

Basically, three types of energy system sources:

1. ATP-PCr system
2. Glycolytic system
3. Oxidative system

And what the heck all these?!

ATP-PCr : An Immediate energy, is said to be Anaerobic as it can operate
with or without oxygen. Every breakdown of ATP-PCr will produce energy.

Glycolytic: A system that produces ATP (energy) from glycolysis (eg: CHO).
Doesn't require Oxygen, so it’s referred to the process of anaerobic (lactic
system).

Oxidative: The Aerobic system. Utilize oxygen in the production of ATP. As
oxygen is used, this is an aerobic process.

These energy systems make a contribution in all types of activities. However one or two will be predominant.

As an example, in the 100meters, the ATP-PCr is the predominant energy system, but both the glycolytic and oxidative systems provide a small portion of the energy needed.

On the other hand, in the 10,000m, the oxidative system is predominant but both ATP-PCr and Glycolytic systems contribute.

Table below is an estimate of percentage (%) contribution of energy system in Track and Field events.

Tyson Gay Takes Diamond League Title, Wins the 100m in 9.79, Nesta Carter improved to 9.85

Carter (9.85 PB), Tyson Gay (9.79), and Blake (9.91)

Tyson Gay defies the cold condition and a false start drama to win the men’s 100m at IAAF Samsung Diamond League Memorial van Damme meeting at Brussell, Belgium (August 27, 2010).

In front of a sell-out 47,000 seats at King Baudouin stadium, Gay had a slow start but surged at the halfway to win the 100m title in 9.79, defeating Jamaica’s Nesta Carter who improved one hundredth of a second of his record to 9.85. Third place went to Carter’s countryman Yohan Black in 9.91.

His time was 0.01 short of his world-leading time set at the IAAF London Diamond League two weeks ago and still 0.21 off Bolt's world record. He earned USD 40,000 and a Diamond Trophy for winning the season-long competition.

Gay who ashamed the world record holder Usain Bolt at Stockholm, also beats Asafa Powell however was disappointed for being denied the chance of going head-to-head with Usain Bolt and Asafa Powell. The two monsters were pulled out due to back injuries.

Meanwhile Allyson Felix added a Diamond League Trophy from the women’s 200m, thus becoming the only athlete at the inaugural Diamond League meeting to win double trophy. Allyson won her first Diamond Trophy last week in 400m at Weltklasse Zurich. Affected by the chill and wet track, Felix won the event in 22.62, beating fellow Americans Shalonda Solomon (22.70) and Bianca Knight (23.01).

Kenya’s David Rudisha, who has broken the men’s 800m world record last week at Berlin, takes the title in a modest time of 1:43.50, defeating the two-times world indoor champion, Abubaker kaki of Sudan who has finished at 1:43.84. Rudisha’s teammate Boaz Lalang was third, clocking 1:44.29. Results and videos are as follows:

David Rudisha Breaks 800m World Record at ISTAF Berlin 2010 in 1:41.09 , Video

Kenyan David Rudisha has broken the men's 800m World record at the ISTAF IAAF World Challenge in Berlin, German on August 22, 2010.

The 21-year-old former World Junior champion clocked 1:41.09 to eclipse the previous mark 1:41.11 set by Wilson Kipketer, a Kenyan-born who went to represent Denmark in 1997 in German.

Special thanks to the pacemaker, Sammy Tangui who did a great job for Rudisha, passing the bell at 48.65. But Tangui shortly stopped, leaving Rudisha alone who started pull away from the field.

I reckon he could be faster if the pacemaker pushes him all the way to 600m!

Rudisha who has 45.50 PB in the 400m reached 600m mark at 1:14.54 but seems no sign of fatigue and speeding through to the line with a new World Record!

In Oslo’s Diamond League meeting in June, he broke Sebastian Coe’s 31-year-old meeting record with a run of 1:42.04.

Then at the KBC Night of Athletics meet in the Belgium in July, Rudisha clocked an impressive 1:41.51, the 2nd fastest of all time. But below is the astounding one:
