The limit is the sprinter’s health. The problematic in sprint training is to achieve the highest sprint volume at the highest intensity POSSIBLE. What makes it possible is the recovery from those workouts, and the condition is to remain healthy in order to progress steadily. Bolt has remained healthy during prolonged period so that he has been able to push his body limits farther than anyone else. Now, unprecedent sets of performances and mediatic exposure has been experience by Bolt in the last couple of years, and he is starting to feel the side effects on his achillis and lower back. How else could it be when you are travelling all around the world, arriving on site of competitions several days before in order to complete the circuit imposed by his 300,000$ appearance fees. How many weeks in a row has he trained this year? How about going back to what he did in 2007 leading to 2008, will he ever find again that peace to train, prepare and get ready for the next events?
Asafa had never ran as well as he did early this season, but unfortunatel his health has not allowed him to build on impressive early races in Doha and Oslo.
Same for Tyson had his wristeling groin. Will he be able to compete soon and at 100% after his 9.78 into head wind and cold heat in London?
