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.

Mar 13: The start of the Indian Premier League (IPL), the world's most lucrative cricket competition, has been postponed from March 29 until April 15 over the coronavirus, the Indian cricket board said Friday.

"The Board of Control for Cricket in India has decided to suspend IPL 2020 till 15th April 2020, as a precautionary measure against the ongoing Novel Coronavirus (COVID-19) situation," the BCCI said in a statement.

The two-month Twenty20 competition is estimated to generate more than $11 billion for the Indian economy and involves cricket's top international stars.

New Delhi, May 12: Chennai Super Kings have rejected the idea of an IPL with only Indian players in the near future, differing with Rajasthan Royals, the franchise which is keen on the option given the circumstances caused by the COVID-19 pandemic.

The IPL, which is indefinitely postponed, can be held in the September-October window if the scheduled T20 World Cup in Australia doesn't take place.

"CSK is not keen to do an IPL with only Indian players. That way it would be playing another Syed Mushtaq Ali Trophy (domestic T20 competition). The franchise has not been in touch with the BCCI of late as the situation is worsening," a CSK source said on conditions of anonymity.

"Let's hope we can have the IPL later this year," he added.

CSK are three-time IPL champions, making them the second most successful team in the event's history after Mumbai Indians, who have won the tournament four times.

The BCCI is also very keen to stage the IPL and if it doesn't happen, the world's richest board would be in financial trouble like Cricket Australia.

"The board will take a revenue hit of Rs 4000 crore if it doesn't happen. The board will be in a big problem," BCCI treasurer Arun Dhumal said earlier this week.

With COVID-19 cases continuing to rise in India, the board and IPL team officials see little point in discussing when the event can be held.

"There has been no discussion with the BCCI ever since it postponed the IPL. There is no point in discussing also as things are unlikely to be okay anytime soon," the CSK source said.

"We expect the BCCI to take the best possible decision when the time comes," he added.

For the IPL to happen with foreign players, travel restrictions, which are currently in place, will have to be eased.

There is an option of conducting the IPL outside India and Sri Lanka Cricket has even offered to host the biggest T20 league in the world.

M S Dhoni was expected to make a much-awaited comeback with the IPL but that too has been postponed indefinitely.

Teammates like Suresh Raina and Piyush Chawla have already spoken about how eager Dhoni was to return.

According to them, Dhoni had the determination of a youngster before the league was suspended due to the lockdown imposed to contain the pandemic.

"Dhoni is his own man but I see him playing the IPL for at least two three years. When it comes to playing for India, only he knows best," the source added.

Last month, Rajasthan Royals executive chairman Ranjit Barthakur had said the franchise was open to a shortened IPL with only Indian players.

"Earlier we could not think of an Indians-only IPL but now there is enough quality to choose from. It is better to have an Indians-only IPL than not have it at all," he had told news agency.

India's cricket board will not push for the Twenty20 World Cup in Australia to be postponed but would consider staging the Indian Premier League (IPL) in the October/November slot if it becomes available, a senior BCCI official has told Reuters.

This year's IPL, which is worth almost $530 million to the BCCI, has been indefinitely postponed because of the COVID-19 pandemic while the World Cup, which is scheduled to begin on Oct. 18, is also in jeopardy.

Reports in Australian media have suggested India's influential board may look to push for the World Cup to be postponed to open up a window for the IPL.

World Cup contingency plans are on the agenda at next week's International Cricket Council (ICC) board meeting but BCCI treasurer Arun Singh Dhumal said India would not be recommending it be pushed back.

"Why should the BCCI suggest postponing the Twenty20 World Cup?" Dhumal told Reuters by telephone.

"We'll discuss it in the meeting and whatever is appropriate, (the ICC) will take a call.

"If the Australia government announces that the tournament will happen and Cricket Australia is confident they can handle it, it will be their call. BCCI would not suggest anything."

While Australia has seen new infections of the novel coronavirus slow to a trickle and is gradually easing travel curbs and social distancing restrictions, hosting a 16-team World Cup would be a Herculean task for Cricket Australia.

Dhumal questioned whether the tournament should go ahead if it had to be played without spectators and said the Australian government would play a key role in any decision.

"It all depends on what the Australian government says on this - whether they'd allow so may teams to come and play the tournament," he added.

"Will it make sense to play games without spectators? Will it make sense for CA to stage such a tournament like that? It's their call."

Cricket Australia chief executive Kevin Roberts was guarded about the prospects of staging the tournament as scheduled on Friday.

"We don't have clarity on that one, yet. But as the situation continues to improve, you never know what might be possible," he said.

"It's ultimately a decision for the ICC."

The ICC has said it was unlikely to make a final call on the fate of the World Cup until August but some boards are in the process of making contingency plans in the event of a postponement.

While the BCCI recognised an open October-November window would suit the IPL, Dhumal said there was no point in making plans until there was some certainty about the World Cup.

"If we have the window available, and depending on what all can be organised, we'll decide accordingly," he added. "We can't presume that it's not happening and go on planning."
