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, Jun 3: Shuttler HS Prannoy has hit out at the Badminton Association of India (BAI) and has questioned the selection criteria for the Arjuna Award.

The shuttler has said that the players who have won nothing have been recommended, while the players who have medals to their credit have been snubbed.

His remarks come as BAI recommended doubles pair of Satwiksairaj Rankireddy and Chirag Shetty and men's singles player Sameer Verma for the Arjuna Award on Tuesday.

"Same old story. Guy who has Medals in CWG and Asian Championships not even recommended by Association. And guy who was not there on any of these major events recommended #waah #thiscountryisajoke," Prannoy tweeted.

Prannoy had been left out from the list last year as well and the shuttler had slammed the criteria then as well.

"If you ever want your name in the awards list, make sure you have people who will get your name to the list. Performance is least considered in our country. Sad state of our county but can't help it. Let go and just play until you can," Prannoy had tweeted last year.

Prannoy had won the mixed team gold at the 2018 Commonwealth Games in Gold Coast and he also has a men's singles bronze medal at the 2018 Asian Championships.

On Tuesday, the BAI has also recommended the renowned National Institute of Sports (NIS)-certified coaches, S. Murlidharan and Bhaskar Babu for the Dronacharya Award.

Murlidharan has been working relentlessly for the growth and development of the sport in Kerala, besides being an able administrator.

He has coached the likes of Vimal Kumar, Rupesh Kumar and Sanave Thomas amongst many other renowned former players.

He has also been a recipient of the Meritorious Service Award given by the Badminton World Federation (BWF) in 1996.

For the Dhyanchand Award, BAI has recommended the names of Pradeep Gandhe and Manjusha Kanwar.

Gandhe is a two-time Asian Games bronze medallist while Manjusha is a South Asian Games silver medallist.

Jun 25: After asserting that the 2011 World Cup final was "sold" by "certain parties" in Sri Lanka to India, the island nation's former sports minister Mahindananda Aluthgamage has now called his claim a "suspicion" that he wants investigated.

The Lankan government has ordered an enquiry into the matter and a special Police investigation unit recorded Aluthgamage's statement on Wednesday. He told the team that he was only suspicious of fixing.

"I want my suspicion investigated," Aluthgamage told reporters.

"I gave to the Police, a copy of the complaint I lodged with the International Cricket Council (ICC) on 30 October 2011 regarding the said allegation as then Sports Minister," he said.

Aluthgamage has alleged that his country "sold" the game to India, a claim that was ridiculed by former captains Kumar Sangakkara and Mahela Jayawardene who demanded evidence from him.

Set a target of 275, India clinched the trophy thanks to the brilliance of Gautam Gambhir (97) and then skipper Mahendra Singh Dhoni (91).

"Today I am telling you that we sold the 2011 world cup, I said this when I was the sports minister," Aluthgamage, who was the sports minister at the time, had stated.

Sangakkara, the captain of Sri Lanka at that time, asked him to produce evidence for an anti-corruption probe.

"He needs to take his 'evidence' to the ICC and the Anti corruption and Security Unit so the claims can be investigated thoroughly," he tweeted.

Jayawardene, also a former captain who scored a hundred in that game, ridiculed the charge.

"Is the elections around the corner...like the circus has started...names and evidence?" he asked in a tweet.

Aluthgamage said that in his opinion no players were involved in fixing the result, "but certain parties were."

Both Aluthgamage and the then President Mahinda Rajapaksa were among the invitees at the final played at the Wankhede Stadium in Mumbai.

Following his allegations, Aravinda de Silva, the former great who was the then chairman of selectors, has urged the BCCI to conduct its own investigation.

De Silva has said he is willing to travel to India to take part in such an investigation despite the current COVID-19 threat.

Mumbai, May 11: The French Open, which was postponed to September from May due to the novel coronavirus outbreak, could be held without fans, the organisers of the claycourt Grand Slam have said.

Roland Garros had been scheduled for May 24 to June 7 before the French tennis federation (FFT) pushed it back to Sept. 20-Oct 4 in a bid to save the tournament from falling victim to the COVID-19 pandemic.

Last week the FFT said all tickets purchased for this year's French Open would be cancelled and reimbursed instead of being transferred.

"Organising it without fans would allow a part of the economy to keep turning, (like) television rights and partnerships. It's not to be overlooked," FFT President Bernard Giudicelli told French newspaper Le Journal du Dimanche.

"We're not ruling any option out."

The tennis season was suspended in early March due to the pandemic and the hiatus will continue at least until mid-July with many countries in lockdown.

Wimbledon has been cancelled while the status of the U.S. Open, scheduled to take place in late August, is still unclear.

COVID-19 Pandemic Tracker: 15 countries with the highest number of coronavirus cases, deaths

The FFT was widely criticised when they announced in mid-March that the French Open would be switched, with players bemoaning a lack of communication as the new dates clashed with the hardcourt season.

Organisers said last week they had been in talks with the sport's governing bodies to fine tune the calendar amid media reports that the Grand Slam tournament would be delayed further by a week and start on Sept. 27.

The delayed start would give players a two-week window between the end of the U.S. Open, played on the hardcourts of New York, and the Paris tournament.

"The 20th or the 27th, that does not change much," Giudicelli said.
