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.

Feb 18: There are no half measures for fit-again New Zealand pace spearhead Trent Boult who is ready to challenge India captain Virat Kohli on his return to international cricket during the two-Test series starting in Wellington on Friday. Boult was out of action for the past six weeks due to a fracture on his right hand sustained during the Boxing Day Test against Australia and missed out on the limited-overs leg of the India series. Back for the traditional format, the left-arm fast bowler made his priorities clear ahead of the first Test.

"That's personally why I play the game, to get guys like that (Kohli) out and test myself against them, so I can't wait to get stuck in. But he's an exceptional player. Everyone knows how great he is," Boult said, sending out a warning after landing in the capital city for the opening Test.

New Zealand's last Test series in Australia was a nightmare as they lost 0-3 and India will be a tough test for the Black Caps.

"They are a great side and they are leading the ICC Test Championship. They are very clear on how they wanted to play the game. It was a tough learning curve in Australia. It's good to see where we are in terms of bouncing back," said Boult.

The Basin Reserve track will have a lot for the seamers and in conducive conditions, a wily customer like Boult will prove to be a handful for the travellers.

"I'm preparing for a solid wicket. It generally is very good here and goes the full distance (five days). I do enjoy playing here, the history that's involved, and it's going to be an exciting week building up. I can't wait to get out there," said the 30-year-old who has taken 256 wickets from 65 Tests.

It was frustrating for him to watch his side get walloped 0-5 in the T20 series but exhilarating when it got its mojo back in the subsequent one-dayers.

The Black Caps won 3-0 in the 50-over format. "I think it is what it is. I have just got to put the last six or so weeks behind me and just back myself to get out there and do my thing," said Boult, who warmed up by playing a club game at the picturesque Taupo ground.

Boult did find a bit of humour in his injury which, for him, was more of an accident.

"If I had to break a hand, (it would) probably be my right one. Breaking a hand, you don't really know how much you use it unless you break it," said Boult.

"I was pushing in off the long run. I think a couple of the clubbies from Taupo really enjoyed that. It was a good afternoon," added the pacer, who sent down eight overs in a friendly game for his club Cadets.

While bowling isn't a problem, Boult is hoping that catching doesn't become an issue.

"Everything has gone very well but catching will be the biggest issue for me," he said.

Professionally, Boult had to lie low due to injury, but it was also a good break as he and wife Lana welcomed their second child.

"Having some time away from the game and having my second son a couple of weeks ago came at quite a good time," said Boult.

Fighting fit, all he wants now is to get hold of a red kookaburra and get a few to tail into Kohli and company.

"I am hungry to be here and can't wait to get back in the white and get the red ball moving around," he said.

Karachi, Jul 3: There was a sense of insecurity among Pakistan players during the 2019 World Cup, claims former chief selector Inzamam-ul-Haq, who also reckons that the PCB should have given Sarfaraz Ahmed more time as captain instead of removing him abruptly.

Inzamam said captains need to be backed since they get better with time.

"Even in the last World Cup I felt the captain and players were under pressure because they were thinking if we don't do well in the tournament we will be out. That environment was created and this is not good for cricket," Inzamam said.

"Sarfaraz achieved some notable victories for Pakistan and was learning to be a good captain but unfortunately when he had learnt from experience and mistakes he was removed as captain," the former captain told a TV channel.

Inzamam remained chief selector from 2016 till the 2019 World Cup. During his tenure, most of the time Sarfaraz remained captain.

Soon after Inzamam was replaced by head coach Misbah-ul-Haq, the Pakistan Cricket Board removed Sarfaraz as a player and captain from all three formats.

"Sarfaraz won us the Champions Trophy and also made the team number one in T20 cricket. He got us some good wins. He should have been given more time as captain by the board but it acted in haste and didn't give him confidence or patience."

The PCB has now given the Test captaincy to senior batsman, Azhar Ali while young batsman Babar Azam leads the side in the white ball formats.

Inzamam, the most capped player for Pakistan, also said that the captain's own performance can dip as he had to focus a lot on other players.

"But a captain learns all this with time. There is no shortcut to it."

He pointed out that people praise Imran Khan’s leadership qualities and captaincy but he also won the World Cup on his third attempt as captain.

"He won the 1992 World Cup because by that time he had become a seasoned captain and learnt to motivate his players and get them to fight in every match."

Inzamam said giving confidence to new players and youngsters is very important for the selectors. He gave the example of Babar Azam.

"Babar struggled initially in Test cricket but we never had any doubt about his ability so we persisted with him and see today where he is standing in all formats."

He also described Babar and pacer, Shaheen Shah Afridi as and future stars.

"Babar is always compared to Virat Kohli but the latter has played a lot more cricket and if you look at their stats and performances at the stage Babar is now, he has not done badly at all."
