Jamaica’s Shericka Jackson has continued to show good speed from all her 200 metre work last year, as she cruised to a Diamond League win over 400-metres in London on Saturday.

Jackson clocked 50.69 seconds as she stepped past countrywoman Stephenie-Ann McPherson, who ran a season’s best, 50.74.

Great Britain’s Laviai Nielson was third in a lifetime best 50.83.

Another Jamaican, Anastasia Le-Roy was also in the race, finishing fourth in 51.46.

Cruising through the first 200 metres, Jackson looked like she may have saved her work for too late, but showed immense speed and strength to overhaul the fading McPherson just before the tape, the result looking far more easy to come by after the fact.

Rounding out the field at the London Diamond League were Poland’s Justyna Swiety-Ersetic, 51.58, Great Britain’s Emily Diamond, 51.69, Slovakia’s Anita Horvat, 51.83, and France’s Amandine Brossiere, 52.03.

  • Fraser-Pryce to release children's book in September Fraser-Pryce to release children's book in September

    Two-time Olympic gold medallist Shelly-Ann Fraser-Pryce will release her new book, ‘I Am A Promise’, in September.

    The 32-yer-old Fraser-Pryce made the announcement on Saturday on social media.

    ‘I Am A Promise’, is a children’s picture book about the indomitable spirit of the six-time Olympic medal winner.

    The book takes readers on Fraser-Pryce's journey from her childhood in the tough inner-city community of Waterhouse in Kingston, Jamaica, through to her development as a young athlete and finally to her first Olympic gold medal in the 100 metres in Beijing, China in 2008.

    The story charts how Fraser-Pryce's commitment to hard work and encouragement from loved ones helped her to achieve every sprinter’s dreams and against great odds. The book encourages young readers to believe in themselves and to maximse their own promise to the world.

    Fraser-Pryce, in a post on Facebook, said, “I am super excited to share my most recent project! My upcoming children’s book, I Am A Promise,  which will be launched in September in select Sangster’s Bookstores locations.

    “Seeing my personal journey depicted in print and colour is such a blessing for me, and I am so humbled to be able to share it with you all.

    “The genesis of this is founded on what I believe is fundamentally important; how we raise our children, the importance of consistent love and nurturing their God-given talents always.

    “This book is extra special for me also as I will be able to read it to Zyon (her son) and teach him these valuable lessons as he grows up."

    In 2016, Fraser-Pryce published her tell-all autobiography, ‘Pryceless Journey’, which detailed her many struggles and obstacles along the path to becoming an Olympic champion.

  • Usain Bolt's 9.58 a decade on: The science behind the world's fastest man Usain Bolt's 9.58 a decade on: The science behind the world's fastest man

    On August 16, 2009, Usain Bolt clocked 9.58 seconds in the final of the 100 metres at the IAAF World Championships in Berlin.

    A decade on, with the eight-time Olympic champion now retired, that world-record time still stands.

    At just 22, the Jamaican obliterated a mark he had set exactly one year earlier at the Olympics in Beijing, shaving more than a tenth of a second of the time.

    Doctor Peter Weyand, a biomechanics expert at Southern Methodist University, told Omnisport what made Bolt so unique.

    A slow starter?

    One of the biggest misconceptions of Bolt was that, due to his 6ft 5in frame, he was a slow starter. Not true, says Weyand. Particularly on that night in Germany when only Dwain Chambers was ahead of him after the first few strides.

    "The most unusual thing was how well he was able to start for somebody as big as he is," Weyand explained.

    "Normally the people that accelerate and get out of the blocks very quickly tend to be the shorter sprinters. The physics and biology of acceleration favours smaller people. In 2009, I think he started as well as anybody in that race. The start was a differentiator."

    Long legs = more force

    Though his height may have given him a slight disadvantage out of the blocks, Bolt's frame came in handy once the race opened up, allowing him to generate more power in the short steps sprinters take.

    "What limits how fast a sprinter can go is how much force they can get down in the really short periods of time they have to do it," Weyand said.

    "If you're going faster, the only way to do what you need to do to pop your body back up with a shorter contact time is to put down more force. What all elite sprinters do is put down more force in relation to their body mass than people who aren't as fast.

    "If you're Bolt and you're 6ft 5in, you have a longer leg and you have more forgiveness. He probably has six, seven, eight milliseconds more on the ground.

    "You have to put down a peak force of about five times body weight and that needs to happen in three hundredths of a second after your foot comes down.

    "He was so athletic and so tall. His long legs gave him more time on the ground."

    Fewer strides, greater success

    Believe it or not, sprinters cannot maintain their top speed for the entire 100m. Bolt, who also holds the 200m world record, had another advantage in that he needed fewer strides to cover the distances.

    "He had 41 steps usually [over 100m] and the other guys are 44, 45, some of the shorter ones are up in the high 40s," Weyand added.

    "Particularly over 200 metres, the step numbers are directly related to fatiguing. If you go through fewer steps and fewer intense muscular contractions to put force into the ground, you have a fatigue-sparing effect."

    Unique, but not perfect

    Given he was able to accelerate out of the blocks quickly – relatively for his height – and was able to use his frame to generate more force across fewer strides, Bolt might have looked like the perfect sprinter.

    But Weyand argued: "You can make a case that Shelly-Ann Fraser-Pryce is the best female sprinter ever and she's 5ft tall.

    "There are trade-offs in terms of being forceful when you accelerate versus having more contact time at your top-end speed."

    Will Bolt's WR ever be broken?

    No current athlete looks close to eclipsing Bolt's time in the near future, but that does not mean his record time will stand forever.

    In 2008, marathon runner and biology professor Mark Denny conducted research and predicted the fastest possible time a male sprinter could run is 9.48secs.

    "Nothing's ever perfect, Bolt's obviously a unique athlete but no race is perfect and no set of circumstances are perfect," Weyand said.

    "Certainly faster than 9.58 [is possible] but that's a question that's hard to answer without being pretty speculative."

    The only thing that is certain is for now – as has been the case for the previous 10 years too – the title of 'the fastest man on earth' belongs to Bolt.
