A fascinating study by exercise physiologist Samuele Marcora has proven that fatigue in endurance is nothing more and nothing less than quitting.
Interview by: Matt Fitzgerald
The design was simple, but the results were profound. Samuele Marcora, an Italian-born exercise physiologist at England’s Bangor University, and his colleague Walter Staiano brought 10 male athletes into their lab and had them perform a simple exercise protocol. Each pedaled on a cycle ergometer as hard as he could for 5 seconds (a test of maximal voluntary cycling power, or MVCP), and his power output was recorded. Then the subjects rode the same bikes as long as they could at a fixed power output level that corresponded to 90 percent of their individual VO2max. Immediately after completing this ride to exhaustion, which ended when the required wattage simply could not be sustained any longer (or approximately 12 minutes, on average), each subject then repeated the 5-second maximum power test.

Michael Johnson’s world record will be in jeopardy.
Jamaican superstar Usain Bolt has confirmed he will race the seldom contested 300m distance at the Golden Spike meeting in Ostrava this May. Bolt has never raced over that distance but says he does workout over 300m often.
Bolt will certainly have his eyes on the world record of 30.85 set by American Michael Johnson in 2000. Bolt proved he could run over 200m succesfully this Spring when he anchored a 4X400m relay team in a blistering 43.58 at the Gibson Relays in Kingston, Jamaica.

Written by: Sean McKeon
Ethiopian great Meseret Defar will look to lower her world record at the 2010 Carlsbad 5000 on April 11th in Carlsbad, Cali. The recently crowned world indoor 3000m champion set her current world record of 14:46 at the 2006 Carlsbad 5000. Defar will square off against 2009 champion Aheza Kiros of Ethiopia. Kiros defeated American Shannon Rowbury 15:38 to 15:41 in 2009.
When asked about racing in Carlsbad again Defar said, “”I have so many great memories of Carlsbad. It will be very special to run there for the 25th anniversary of the race. Everyone knows how fast the course is and if we get a good day it would be great to try and challenge my world record.”

Why lift weights when you can run against gravity?
Written by: Brad Hudson
One of the signature training methods I use with my runners in the Marathon Performance Training Group are steep hill sprints. These short, maximum-intensity efforts against gravity provide two key benefits. First, they strengthen all of the running muscles, making the runner much less injury-prone. They also increase the power and efficiency of the stride, enabling the runner to cover more ground with each stride with less energy in race circumstances. These are significant benefits from a training method that takes very little time and is fun to do.
