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.

Islamabad, Aug 7: Former Pakistani fast bowler Shoaib Akhtar, known for his blistering deliveries on the cricket field, recently baffled many with a deadly off-field bouncer by claiming he is willing to eat grass if it enabled an increase in budget for his country's Army!

"If Allah ever gives me the authority, I will eat grass myself but I will increase the budget of the army," said Akhtar in an interview with ARY News.

The 'Rawalpindi Express', considered the fastest bowler in history said he does not understand why the civilian sector cannot work in collaboration with the Armed forces.

"I will ask my army chief to sit with me and make decisions. If the budget is 20 per cent, I will make it 60 per cent. If we insult each other, the loss is ours only," the once feared fast-bowler said.

Akthar had also claimed to ARY News interview that he was willing to take a bullet for his country and had turned down a county stint just because he wanted to fight the 1999 Kargil War.

Ties between India and Pakistan have been strained in the recent months over several issues, the latest being Pakistan's attempt to broach in the UNSC the issue of Kashmir on the first anniversary of the India's move to scrap the special status of Jammu and Kashmir and to split the erstwhile state into two union territories .

Pakistan also has not been in a good financial position and under prime minister Imran Khan, himself an all rounder cricketer, has added nearly USD 22 billion, that is 35 per cent to the nation's international debt pile in the last two years, according to an Asia Times report in July.

While Pakistan recently received USD 1.39 billion from the IMF to cushion the economic shocks caused due to COVID-19 outbreak, Akthar had a few months ago proposed that a joint cricket match be played between India and Pakistan to raise funds to fight the coronavirus. The suggestion that was put down by cricketers in India.

Meanwhile the 'Pindi boy' whose deadly pace and bounce was once dreaded by batsmen had recently taken to Twitter to deny former India cricketer Virender Sehwag's claim of sledging him.

Sehwag along with other Indian crickerters such as Harbhajan Singh and even Rahul Dravid had been at the receiving end of Akthar's sledging and antics during their playing days.

"Yes, totally self made story by him. Mujhe yeh bol k bach k jana kidhar tha us nay," Akthar tweeted to a report in which Sehwag claimed that he had sledged the 'Rawalpindi Express' by telling him that Sachin Tendulkar was his father.

During an awards ceremony Sehwag had recounted that fed up with Akthar's sledging and retaliated by telling him to say the same things to Tendulkar, who smashed the 'Pindi boy' for a six. Sehwag quipped that he told Akthar then that "Baap baap hota hai".

In the recent ARY interview, asked about the allegation made against him by former India cricketer Virendra Sehwag that he makes pro-India comments for greater following on social media channels, Akhtar said, "I cannot talk on the basis of hate."

Tokyo, Apr 14: Tokyo organizers said Tuesday they have no B Plan in the event the Olympics need to be postponed again because of the coronavirus pandemic.

Masa Takaya, the spokesman for the Tokyo Olympics, said organizers are proceeding under the assumption the Olympics will open on July 23, 2021. The Paralympics follow on Aug. 24.

Those dates were set last month by the International Olympic Committee and Japanese officials after the coronavirus pandemic made it clear the Olympics could not be held as scheduled this summer.

We are working toward the new goal, Takaya said, speaking in English on a teleconference call with journalists.

We don't have a B Plan. The severity of the pandemic and the death toll has raised questions if it will even be feasible to hold the Olympics in just over 15 months. Several Japanese journalists raised the question on the call.

All I can tell you today is that the new games' dates for both the Olympic and Paralympic Games have been just set up, Takaya said.

In that respect, Tokyo 2020 and all concerned parties now are doing their very best effort to deliver the games next year." IOC President Thomas Bach was asked about the possibility of a postponement in an interview published in the German newspaper Die Welt on Sunday.

He did not answer the question directly, but said later that Japanese organizers and Prime Minister Shinzo Abe indicated they could not manage a postponement beyond next summer at the lastest.

The Olympics draw 11,000 athletes and 4,400 Paralympic athletes and large support staffs from 206 national Olympic committees.

There are also questions about frozen travel, rebooking hotels, cramming fans into stadiums and arenas, securing venues, and the massive costs of rescheduling, which is estimated in Japan at 2 billion- 6 billion.

Tokyo 2020 CEO Toshiro Muto addressed the issue in a news conference on Friday. He is likely to be asked about it again on Thursday when local organizers and the IOC hold a teleconferene with media in Japan.

The other major question is the cost of the delay; how much will it be, and who pays? Bach said in the Sunday interview that the IOC would incur several hundred million dollars in added costs. Under the so-called Host City Agreement, Japan is liable for the vast majority of the expenses.

This is impossible to say for now, Takaya, the spokesman said.

It is not very easy to estimate the exact amount of the games' additional costs, which have been impacted by the postponement."

Tokyo says it's spending 12.6 billion to organize the Olympics. But a Japanese government audit published last year says the costs are twice that much. Of the total spending, 5.6 billion in private money. The rest is from Japanese governments.

New Delhi, Jun 18: Premier Indian off-spinner R Ashwin has described Mahendra Singh Dhoni as a "massive influence" on his career, revealing that at the beginning of his IPL stint, he was driven by an intense desire to get the former captain's attention.

Ashwin got his contract with CSK, one of the most successful IPL sides, in 2008 and said the stint with CSK shaped his career.

"IPL and CSK is a stage that everyone wants. For me it was more about recognition. MSD did not know who Ashwin is, (Matthew) Hayden and (Muttiah) Muralithan did not know who Ashwin is. The first thing that came to my mind was that 'I will show these people that Ashwin is here'," Ashwin told Harsha Bhogle on 'Cricbuzz in Conversation'.

"I don't know it was being foolish or arrogance but that was how I was made. Nobody was giving me a chance that Ashwin will play alongside Muralitharan or ahead of Muralitharan. I thought, I will get there ahead of him one day," he added.

Ashwin said Dhoni, who led CSK, had "massive influence" on him and the only way to impress him was by troubling him in the nets.

"I got the eye of Hayden, Jacob Oram, and Stephen Fleming while bowling to them at the nets. They were finding it difficult to face me in the first year (2008) but I had not caught the eye of MSD," he said.

"I never had massive interactions with him. It was going to the nets and getting MSD...he was hitting Muralitharan out of the park and I thought, if I bowl better than him, I met get to play ahead of Murali.

" I got his attention when I got him during a Challenger trophy and celebrated like a crazy kid," he recalled.

After that, Ashwin said during CSK's match against Victoria Bushrangers in the now defunct Champions League, he volunteered to bowl the Super Over and Dhoni gave him the ball without hesitation.

Ashwin did not fare well and ended up conceding 23 runs. The off-spinner said when Dhoni walked past him after the match, he only said that, "you should have bowled the carrom ball."

"MS always maintained that you are exceptionally skilful and you should keep doing what you do."

Ashwin has been very successful against the left-handers as 189 of his 365 wickets are of southpaws. Ashwin credited his engineering background and advice from Duncan Fletcher for the success.

"He made a statement that changed cricket. He said it's all about geometry and left it at that. Understanding angles (engineering background) has given me edge over others," he said.
