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.

Mar 5: India reached a maiden women's Twenty20 World Cup final Thursday after their last four clash against England was washed out, sparking calls for the International Cricket Council to include reserve days in future events.

Harmanpreet Kaur's unbeaten side were due to face the 2009 champions at the Sydney Cricket Ground, but the rain began pouring early in the day with barely any let-up.

With a minimum 10 overs per side needed for a result and no break in the weather, the umpires called it off without a ball being bowled.

Normally, five overs per side are needed to constitute a Twenty20 match, but the rules are different for ICC tournaments.

Four-time champions Australia are scheduled to take on South Africa later in the second semi-final, with that match also under threat.

With no reserve day, the highest-ranked teams from the two groups move into the final if play is not possible

That would pit India against South Africa at the Melbourne Cricket Ground on Sunday, where organisers are hoping to attract 90,000 plus fans, denying Australia a chance to defend their crown.

A reserve day is allowed for the final and the lack of one for the semis has been criticised by some players, with England captain Heather Knight among those calling for change.

"If both semi-finals are lost it would be a sad time for the tournament," she told reporters ahead of the match. "It's obviously going to be a shame if it does happen and I'm sure there will be a lot of pressure on the ICC to change that."

Cricket Australia chief Kevin Roberts said he sought clarification from the ICC about adding a reserve day with the Sydney weather looking ominous, but the request was denied.

"We've asked the question and it's not part of the playing conditions and we respect that," he told Melbourne's SEN radio.

"It gives you cause to reflect and think about how you might improve things in the future, but going into a tournament with a given set of playing conditions and rules, I don't think it's time to tinker with the rules."

It is not the way India would have wanted to make the final, but they are deserving of being there having gone through the group phase as the only unbeaten team.

After opening their campaign by upsetting Australia, they beat Bangladesh, New Zealand and then Sri Lanka.

While the entire team played well, teenage batting prodigy Shafali Verma excelled, which saw her elevated to the top of the ICC T20 batting rankings this week aged just 16.

She is only the second Indian after Mithali Raj to reach number one, pushing New Zealand veteran Suzie Bates down to second.

Ranked four in the world, India had made three semi-finals before this year and lost every time, including against England at the last World Cup.

The International Cricket Council (ICC) today confirmed the ICC Men’s T20 World Cup in Australia 2020 has been postponed due to the ongoing COVID-19 pandemic

At today’s meeting of the IBC Board (the commercial subsidiary of the ICC), windows for the next three ICC men’s events were also agreed to bring clarity to the calendar and give the sport the best possible opportunity over the next three years to recover from the disruption caused by COVID-19.

The windows for the Men’s events are:

1. ICC Men’s T20 World Cup 2021 will be held October – November 2021 with the final on 14 November 2021

2. ICC Men’s T20 World Cup 2022 will be held October – November 2022 with the final on 13 November 2022

3. ICC Men’s Cricket World Cup 2023 will be held in India October – November 2023 with the final on 26 November 2023

The IBC Board agreed to continue to monitor the rapidly changing situation and assess all the information available in order to make a considered decision on future hosts to ensure the sport is able to stage safe and successful global events in 2021 and 2022.

The IBC Board will also continue to evaluate the situation in relation to being able to stage the ICC Women’s Cricket World Cup 2021 in New Zealand in February next year. In the meantime, planning for this event continues as scheduled.

The Board will also continue to evaluate the situation in relation to being able to stage the ICC Women’s Cricket World Cup 2021.

ICC Chief Executive Manu Sawhney said: “We have undertaken a comprehensive and complex contingency planning exercise and through this process, our number one priority has been to protect the health and safety of everyone involved in the sport.

“The decision to postpone the ICC Men’s T20 World Cup was taken after careful consideration of all of the options available to us and gives us the best possible opportunity of delivering two safe and successful T20 World Cups for fans around the world.

“Our Members now have the clarity they need around event windows to enable them to reschedule lost bilateral and domestic cricket. Moving the Men’s Cricket World Cup to a later window is a critical element of this and gives us a better chance of maintaining the integrity of the qualification process. This additional time will be used to reschedule games that might be lost because of the pandemic ensuring qualification can be decided on the field of play.

“Throughout this process we have worked closely with our key stakeholders including governments, Members, broadcasters, partners and medical experts to enable us to reach a collective decision for the good of the game and our fans. I would like to thank everyone involved for their commitment to a safe return to cricket.”
