A problem in his lower back that "restricts his ability to generate power to his stride" has force double world record-holder Usain Bolt to pull the plug on his 2010 season with two European meets to go. A release from Bolt's agent Ricky Simms of Pace Sports Management yesterday said an "assessment from his medical team...found a problem in his lower back.
He has a tightness that restricts his ability to generate power in his stride and continuing to race in this condition could risk injury to his hamstrings or calf muscles". Bolt, who missed part of the season with an Achilles tendon problem was examined by world-renowned specialist Dr Hans Müller-Wohlfahrt in Munich, Germany, on Monday when the decision was taken to shut him down for the remainder of the season.
The release said further, "With a view to his future career we believe further treatment to loosen his back followed by a period of rest will be in his best interest." Bolt, who will turn 24 later this month and who holds the world records in the 100m- 9.58 seconds and the 200m- 19.19 seconds, both set last year at the IAAF World Championships in Berlin, Germany, will miss the IAAF Diamond League meetings — Weltklasse Zurich and Memorial van Damme, Brussels.
