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, Jul 1: After being named as India's 'Most Valuable Player' in Test cricket in the 21st century, all-rounder Ravindra Jadeja on Wednesday said that he will always aim to give his best for the country.

His remark came as Jadeja achieved an MVP rating of 97.3 and as a result, he was also rated as the second most valuable player Test player worldwide, only second to Sri Lanka's Muttiah Muralitharan.

"Thank you Wisden India for naming me the 'Most Valuable Player'. I would like to thank all my teammates, coaches, fans, and well-wishers for your support as I aim to give my best for our country. Jai Hind," Jadeja tweeted.

Based on CricViz's market-leading analytics, each player in world cricket was awarded an 'MVP rating' by Wisden using a statistical model to rank their 'match impact' compared to their peers.

Jadeja has played in 49 Tests from 2012, managing to score 1,869 runs and has also picked up 213 wickets.

"It might come as a surprise to see Ravindra Jadeja, India's spin-bowling all-rounder, feature as India's number one. After all, he's not even always an automatic pick in their Test team. However, when he does play he is picked as a frontline bowler and has batted as high as No.6 - contributing to a very high match involvement," the official website of Wisden quoted CricViz's Freddie Wilde as saying.

"But Jadeja's position is based on more than simply volume: it's what he does when he's involved that really counts. The 31-year-old's bowling average of 24.62 is better than Shane Warne's and his batting average of 35.26 is better than Shane Watson's. His batting and bowling average differential of 10.62 runs is the second-best of any player this century to have scored more than 1,000 runs and taken 150 wickets. He is an all-rounder of the very highest quality," he added.

With the bat in hand, Jadeja has managed to score one century and 14 fifties in the longest format of the game.

He was last seen in action during India's two-Test series against New Zealand earlier this year.

He would have been in action for the Chennai Super Kings (CSK) in the IPL had the tournament commenced from March 29.

However, the IPL has been postponed indefinitely due to the coronavirus pandemic.

New Delhi, Apr 26: The idea of having a full-fledged women's IPL is in a "progression stage" and a World Cup title for India can actually help in turning that into a reality sooner than later, says former captain Anjum Chopra.

Under the leadership of Harmanpreet Kaur, the Indian team sailed into the final of the last women's T20 World Cup, but was thrashed by home favourites and defending champions Australia when it mattered the most.

Chopra, one of the country's most decorated women cricketers, said a World Cup title triumph would have brought about a generational shift to the women's game in cricket-mad India.

"Women's IPL in the progression stages. From one game at the start we had four last year in the Women's T20 Challenge, and this time it was supposed to be seven. It has progressed," Chopra said.

"If the women's team had won the World Cup this year, the number of matches would have been more. There is a big difference between winners and runners up."

Chopra had a successful career spanning over 17 years during which she represented India in six World Cups while becoming the first woman cricket to appear in 100 One-day Internationals.

She added, "A victory (in final of last T20 World Cup) would have been a complete generational shift in a much more progressional manner."

Referring to the rapid strides the women's game has made the world over, she praised the International Cricket Council (ICC) for "consciously building it up".

"ICC has bifurcated viewership numbers also very well for Indian audience."

The icing on the cake was a near-packed Melbourne Cricket Ground (MCG) for the World Cup final between India and Australia, and that was not lost on Chopra, who is now a respected analyst and sportscaster.

"To have 80,000 people watching the final that's commendable. That definitely a boost," said Chopra, who holds the distinction of leading India to their first ever Test series win.

A World Cup triumph and the "mind set would have gone to different level altogether", she believed.

Asked about the chatter around pay disparity in Indian cricket, her simple message was win more to earn more.

"There is already pay parity in Australia. Because both teams have won the World Cups more than any other nations.

"If you start winning, then I am sure things will be different. It's also about how much you are able to generate as a team.

"I would say sky is the limit for them."

With the COVID-19 pandemic bringing sporting activities to a standstill, a cloud of uncertainty hangs over the fate of many big events lined up in the near future.

While the IPL has been put on hold indefinitely, the pandemic has thrown the men's T20 World Cup, scheduled for October-November in Australia, into doubt.

"There has been a suggestion that if we are hosting the World Cup in October, then play the IPL as preparation ground for World Cup."

That is only if the situation improves in the coming times.

"It's difficult to see, to gauge where sport will be after this. For sure it is not going to be where it was before. Even if it opens up tomorrow it couldn't be the same.

"Can sports people can get back to work without worry? We don't know when this is going to be under control."

Potchefstroom, Feb 9: Defending champions India are overwhelming favourites to win a record fifth U19 World Cup title on Sunday but a tough fight is expected from first-timers Bangladesh in an all-Asian final.

If the India squad for the 2018 edition had the likes of Prithvi Shaw and Shubman Gill, who have expectedly gone on to play for the senior team, the exploits of opener Yashasvi Jaiswal, spinner Ravi Bishnoi and pacer Kartik Tyagi in the current edition have made them overnight stars.

Irrespective of what happens in the final, India have reinforced the fact that they are undisputed leaders at the under-19 level and the cricketing structure the BCCI has developed is working better than any other board in the world.

India, who walloped arch-rivals Pakistan by 10 wickets in the semifinal Tuesday, will be playing their seventh final since 2000 when they lifted the trophy for the first time.

Having said that, success at the U-19 level doesn’t guarantee success at the highest level as not all players have the ability to go on and play for India. Some also lose their way like Unmukt Chand did after leading India to the title in 2012.

His career promised so much back then but now it has come to a stage where he is struggling to make the eleven in Uttarakhand’s Ranji Trophy team, having shifted base from Delhi last year.

Only the exceptionally talented like Shaw and Gill get to realise their dream as the competition is only getting tougher in the ever-improving Indian cricket.

India probably is the only side which fields a fresh squad in every U-19 World Cup edition and since there is no dearth of talent and a proper structure is in place, the talent keeps coming up.

“The fact that we allow a cricketer to play the U-19 World Cup only once is a big reason behind the team’s success. While most teams have cricketers who have played in the previous edition,” India U-19 fielding coach Abhay Sharma said from Potchefstroom.

“It just goes to show that the system under the visionary leadership of Rahul Dravid (NCA head) is flourishing. Credit to BCCI as well that other teams want to follow our structure.”

Heading to the mega event, India colts played about 30-odd games in different part of the world. To get used to the South African conditions, they played a quadrangular series before they played their World Cup opener against Sri Lanka.

In the final, India run into Bangladesh, a team which too has reaped the benefits of meticulous planning since their quarterfinal loss at the 2018 edition.

Though the Priyam Garg-led Indian side got the better of them in the tri-series in England and Asia Cup last year, Bangladesh has always come up with a fight and fielding coach Sharma expects it would be no different Sunday.

They are a very good side. There is a lot of mutual respect. I can tell you that,” he said.

Considering it is their maiden final, it is a bigger game for Bangladesh. If they win, it will be sweet revenge against the sub-continental giants, who have found a way to tame Bangladesh at the senior level in close finals including the 2018 Nidahas Trophy and 2016 World T20.

“We don’t want to take unwanted pressure. India is a very good side. We have to play our ‘A’ game and do well in all three departments. Our fans are very passionate about their cricket. I would want to tell them, keep supporting us,” said Bangladesh skipper Akbar Ali after their semifinal win over New Zealand.
