Kingston (Jamaica), April 16 (IANS/CMC): Sprint superstar Usain Bolt says he is confident he can smash two records he set five years ago at the World Championships in Berlin.

The 27-year-old vowed to lower the times on the 100 and 200 metres after he resumed training at the weekend following an injury, reports CMC.

Bolt’s records stand at 9.59 and 19.19 for the 100 metres and half lap, respectively.

"I have discussed with my coach what it will take to lower these records, and he thinks it's very possible," said Bolt, who is coached by Glen Mills at the Racers Track Club.

"I trust my coach completely, so if coach Mills says they can be broken, then I know I can lower them."

Bolt’s manager Ricky Simms had reported that his foot was sore a few weeks ago.

However, the five-time IAAF World Male Athlete of the Year said he is not bothered by the setback and that he expects to be back to his best soon.

"(The injury) is nothing serious ... my experience has taught me that that's just the nature of the sport," Bolt told The Gleaner Tuesday.

"Setbacks are a part of track and field. I have come to accept that a long time ago. I had mine, and (I'm) now back in training preparing for the upcoming season."

Bolt says he is looking forward to posting strong times this season which includes next month's IAAF World Indoor Relays in The Bahamas.

"(The IAAF World Relays) should be a lot of fun. Relays are always the best part of any championship for me,” Bolt said.

"Jamaica has a lot of talented athletes, so I have no doubt that we can lower the (4x200m) record," he added, without confirming whether he will actually be able to compete at the May 24 and 25 championships.
