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.

Melbourne, Apr 14: As all sporting action across the world has come to a halt due to the coronavirus pandemic, Australian bowlers are pondering as to how Indian skipper Virat Kohli might play in front of no spectators.

India and Australia are scheduled to play a four-match Test series later this year, and it is being speculated that the series might end up taking place without any crowds due to the COVID-19 pandemic.

Australian spinner Nathan Lyon on Tuesday said that it would be interesting to see how Kohli goes about it if he does not get a chance to get the audience behind him.

"He is probably good enough to adapt to any scenario. But I was talking to Mitch Starc the other day and we actually said that if we are playing with no crowd, it'll be quite amazing to see Virat trying to rev up the empty seats," cricket.com.au quoted Lyon as saying.

"It is going to be a little bit different, but Virat is a superstar. He will be able to adapt to any climate that we are able to play in," he added.
During the 2018-19 series, India managed to defeat Australia in Australia for the first time in a Test series.

Australia, at that time were without the services of David Warner and Steve Smith. However, the series later this year promises to be a mouth-watering prospect.

"I am excited about the prospect of India coming out to Australia, it's up there with the biggest series alongside the Ashes. They are an absolute powerhouse of the cricket world, and to have those guys out here is going to be fantastic. Playing in front of crowds or no crowds is out of our control, we have got to follow the advice of all the amazing medical people around the world," Lyon said.

"I have not thought about no crowds or massive crowds, it is just about the opportunity of playing against India again. They had the wood over us last time they came over here but we are a much stronger Australian cricket side at the moment, and I am just unbelievably excited about playing them here at home," he added.

Lyon was slated to represent Hampshire in County Championship this year, however, his stint was called off last week due to COVID-19.
He is Australia's third-highest wicket-taker in the longest format of the game as he has total of 390 wickets in Test cricket.

Lyon was last seen in action in the Big Bash League for Sydney Sixers.

Pakistan Cricket Board Chairman Ehsan Mani on Wednesday said apart from centrally-contracted players contributing Rs 5 million, the employees in the board, up to the senior manager level, will contribute their one day's salary.

Those employed as general managers or on higher posts will give two days' salary to the fund.

Pakistan has recorded more than 1,000 positive cases of the deadly virus, which has claimed more than 19,000 lives all over the world.

"It is the history of the cricket board that we always stand by the government in difficult times," Mani said.

The PCB has already given its high performances centre in Karachi at the national stadium to be used by paramedical staff working at the special coronavirus hospital set up at the expo centre in the in the city.

Potchefstroom, Feb 10: India's under-19 cricket team manager Anil Patel says the ICC has taken a serious view of the aggressive celebrations by Bangladesh players after their World Cup triumph and will be reviewing the footage of the final game's "last few minutes".

Some Bangladeshi players got carried away while celebrating their historic three-wicket win over India in the final on Sunday. While their captain Akbar Ali apologised for the "unfortunate incident", his Indian counterpart Priyam Garg said their reaction was "dirty".

"We don't know what actually happened," Patel told 'ESPNCricinfo' on Sunday.

"Everybody was in a shock, absolutely, but we don't know what happened exactly. The ICC officials are going to watch the footage of the last few minutes and they are going to let us know," he said.

Even when the match was on, the Bangladesh players were overly aggressive while fielding and their lead pacer Shoriful Islam sledged the Indian batsmen after every delivery.

As soon as the match ended, it became tense with Bangladeshi players rushing to the ground and displaying aggressive body language. The two teams nearly came to blows before the situation was defused by the coaching staff and on-field officials.

Patel claimed that match referee Graeme Labrooy met him and expressed regret at what transpired on the field.

"The referee came to me. He was sorry about the incident. He clarified the ICC is going to take very seriously what has happened during the match and the last session. They are going to witness the footage and they will tell us in the morning (Monday)."
