Dušan Mravlje  

Feel the pulse  
The quiescent pulse is one possible indicator for the physical power of human beings. The less strokes the heart takes, to circulate the blood through the body, the better is the staying power of that athlete. Normal sports enthusiasts have depending on their age a quiescent pulse of 50 to 70. Ultramarathon runners often reach 30 strokes per minute. The 47-year old Dušan Mravlje says his pulse frequence is “about 40”. He wouldn’t know it exactlier. But it had to be a little quicker due to his beloved Slowenian wine that he drinks now and then, Dušan explains with a grin. 

During a race Dušan never wears a pulse-meter like many other runners do. "I can feel my pulsation." He could keep his pulse up in an optimal range for him between 120 and 135 without any technical assistance.
