Incheon: The prospect of an Asian-born athlete breaking the 10-second barrier for the 100 metres is still a long way off, two top sprinters said.
China`s Su Bingtian and Kei Takase admitted they had a lot of work to do to reach the landmark, after losing the Asian Games sprint final to Qatar`s Nigeria-born Femi Ogunode.
Su`s time of 10.10 was the second quickest by an Asia-born athlete in 2014 but it was only enough for silver.
Ogunode`s 9.93 took 0.02 seconds off the old Asian record -- also set by a Nigerian-turned-Qatari, Samuel Francis.
Su, who has run a 10.06 sec admitted he felt off the pace.
"To run 100m under 10 seconds is a goal many athletes in China are striving for," Su said.
"But my training and technique aren`t good enough yet and I need to do a lot better."
China and Japan once dominated Asian sprinting, but their athletes are struggling to match Qatar`s African imports.
Takase, who has run 10.02 but could only manage 10.15 for bronze in the Asiad final on Sunday, said the problem was partly mental.
"I have always strived to go below 10 seconds in the 100m," he said.
"For me to succeed with that goal I need to train harder -- both body and mind -- to improve my times."
There had been high hopes that China`s Zhang Peimeng, who has run a 10.00, could deliver, but he struggled to find his rhythm in Incheon and could only muster 10.18.
Japan`s teenage sprint star Yoshihide Kiryu, who clocked 10.01 as a schoolboy last year, was ruled out through injury.
