In world record, Bolt triumphed over air

July 26, 2013

Bolt_triumphedParis, Jul 26: Scientists today said Usain Bolt performed a feat of biomechanics when he ran 100m in a record 9.58sec at the 2009 World Championships in Berlin.

Crossing the line in a time that is still a world record meant Bolt had to muster "truly extraordinary" power and energy to overcome exceptional drag, they said.

Taking into account the altitude of the Berlin track, the temperature at the time of the race and the resistance caused by Bolt's 1.95m (six feet five inch), 94-kilo (207-pound) frame, the researchers calculated he had a drag coefficient of 1.2, which is less aerodynamic than the average human.

Bolt hit peak power after only 0.89 seconds, expending 81.58 kilojoules of energy by the time he finished the race.

But 92.21 percent of this energy was used to overcome air resistance, according to a paper appearing in the European Journal of Physics. Only 7.79 percent was used to achieve motion. After 41 strides, he crossed the line at 43.92 kilometres (27.29 miles) per hour.

"The enormous amount of work that Bolt developed in 2009, and the amount that was absorbed by drag, is truly extraordinary," said scientist Jorge Hernandez from the National Autonomous University of Mexcio.

"It is so hard to break records nowadays, even by hundredths of a second, as the runners must act very powerfully against a tremendous force which increases massively with each bit of additional speed they are able to develop.

"This is all because of the 'physical barrier' imposed by the conditions on Earth. Of course, if Bolt were to run on a planet with a much less dense atmosphere, he could achieve records of fantastic proportions."

The team compared Bolt's time in Berlin with his previous world-record time, of 9.69sec, set during the 2008 Beijing Olympics. In Berlin, he benefited from a tiny tailwind of 3.23 kph (2 mph), the researchers found.

Without this boost, he would have come in at 9.68sec, thus beating the previous mark by 0.01sec. The analysis was made from data provided by the International Association of Athletics Federations (IAAF), whose laser tracker recorded Bolt's position and speed every 0.1 of a second in Berlin.

New Delhi, Mar 31: Australia batsman David Warner on Tuesday decided to shave off his head to show support towards all those people who are working relentlessly on the frontline in the battle against coronavirus.

After shaving off his head, Warner also challenged his Australian team-mate Steve Smith and India skipper Virat Kohli to do the same.

Warner, shared a time-lapse video on Instagram, of him shaving his head, and captioned the post as: "Been nominated to shave my head in support of those working on the frontline #Covid-19 here is a time-lapse. I think my debut was the last time I recall I've done this. Like it or not".

Due to the coronavirus pandemic, Australia's death toll stands at 19, as per the Sydney Morning Herald.

As of 8 am today, 4460 people across Australia have tested positive for COVID-19.

The World Health Organisation had termed coronavirus as a 'pandemic' on March 11.

Earlier in the day, Australia Test skipper Tim Paine also confirmed that the side's tour of Bangladesh is unlikely due to the virus spread.
"You don't have to be Einstein to realise (the Bangladesh tour) is probably unlikely to go ahead, particularly in June. Whether it's cancelled or pushed back, we're not quite sure at the moment," cricket.com.au quoted Paine as saying.

Currently, Australia has 296 points in the WTC from 10 matches, while India has 360 points from nine matches.

May 28: Former India captain and Kings XI Punjab head coach Anil Kumble is hopeful of the IPL happening this year and is not averse to the idea of conducting the cash-rich event without spectators due to the COVID-19 threat.

It is not official yet but there is speculation that the BCCI wants to hold the IPL in the October window after the tournament was postponed indefinitely earlier this year due to the COVID-19 pandemic.

"Yes we are hopeful and optimistic that there is still a possibility (to hold IPL this year) if we can cram in the schedule," Kumble was quoted as saying by Star Sports show 'Cricket Connected'.

"If we are going to have a stadium without spectators, then probably have 3 or 4 venues; there's still a possibility, we are all optimistic," said the former spinner, who is also the chairman of ICC's Cricket Committee.

Former India batsman VVS Laxman said the stakeholders can stage the league in cities which have multiple stadia to reduce travelling by players.

"Absolutely (there is chance to hold IPL this year), and also make sure that all the stakeholders have a say," he said.

"...you should identify one venue, which probably has 3 or 4 grounds; if at all you find that kind of a venue because travel is again going to be quite challenging," said the former stylish batsman.

"You don't know who's going to be where at the airports, so that I'm sure the franchises and the BCCI will be looking into."

New Delhi, Jan 31: Indian women's team captain Rani Rampal on Thursday became the first-ever hockey player to win the prestigious 'World Games Athlete of the Year' award.

The World Games announced the winner on Thursday after 20 days of polling by sports fans world-wide.

"Indian hockey superstar Rani is The World Games Athlete of the Year 2019! Huge congratulations!," the World Games said in a statement.

"With an impressive number of votes, 199,477, Rani is the clear winner of the Athlete of the Year race, where sports fans all over the world have voted for their favourite during 20 days of polling in January. All in all, over 705,610 votes were cast during the poll," it added.

Last year, India won the FIH Series Finals, and Rani was named Player of the Tournament. Under Rani's leadership, the Indian women's team qualified for just the third Olympic Games in its history.

"I dedicate this award to the entire hockey fraternity, my team and my country. This success has only become possible with the love and support from hockey lovers, fans, my team, coaches, Hockey India, my government, friends from Bollywood, fellow sportspersons and my countrymen who have continuously voted for me," said Rani, who was recently named among the Padma Shri awardees.

"Special thanks to FIH for nominating me for this prestigious award. Thank you to The World Games Federation for this recognition," she added.

Rani further said after a successful 2019, she is now looking forward to achieving greater heights with the national team in 2020, which also happens to be an Olympic year.

"It is my privilege and honour to win this award. It is always nice when your country recognises your effort. It is even better when the international sports community recognises it. Thank you so much to everyone who voted for me," she said.

"2019 was a great year for our team because we qualified for the 2020 Tokyo Olympic Games. As a team we want to make 2020 a great year!"

Rani, who has been a member of the national team since she was a 15-years-old, currently has more than 240 caps for India.

"Rani is an inspirational athlete, and a role model for many in India. It was amazing to see the support the Indians, even as high up as Mr Rijiju, the Minister of State, Youth Affairs and Sports, gave to her in this vote together with the Hockey fans all around the world. This is what sport is about: uniting people from different backgrounds and different countries," said International World Games Association President Jose Perurena.

The International Hockey Federation also congratulated Rani on being named for the award.

"Congratulations @imranirampal for becoming the first ever Hockey athlete to win the prestigious @TheWorldGames Athlete of the Year award!" the FIH, who nominated Rani for the award, said in its twitter handle.

"On behalf of FIH and the global hockey community, I would like to extend our warmest congratulations to Rani for having been voted The World Games Athlete of the Year 2019. This is an acknowledgement of her outstanding performances - together with her team-mates - and her dedication to hockey and her leadership," FIH CEO Thierry Weil said.

"This prestigious Award is also a great recognition for hockey globally. Furthermore, we are working hard for and looking forward to having Hockey 5s as a demonstration sport at The World Games 2021."

Congratulating Rani, Hockey India President Mohd Mushtaque Ahmad said, "This is a very proud moment for all of us. She is the first Indian athlete to win this award and through her achievements Rani has been able to draw a lot of attention towards women's hockey. Many people are aware of the team's recent accomplishments and I am confident this team is capable of winning larger goals and I wish Rani and the team best of luck this Olympic Year."

There were initially 25 nominees, male and female nominated by their respective sports federations, which was later reduced to 10 in the final round of public voting.

The FIH has recommended Rani's name for her outstanding performances and her ability to lead by example.

Karate star Stanislav Horuna of Ukraine was second behind Rani with over 92,000 votes and Canadian powerlifting world champion Rhaea Stinn was third.
