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.

Karachi, May 25: Pakistan head coach and chief selector Misbah-ul-Haq believes Babar Azam is destined to be a world-class player and is very close to being in the same league as India skipper Virat Kohli and Australia's Steve Smith.

"I don't like comparisons but Babar is currently very close to being in the same class as Virat Kohli, Steve Smith or Joe Root," Misbah said in an interview to Youtube channel, Cricket Baaz.

"He believes in the work ethic that if you want to better Kohli you have to work harder than him at your skills, fitness and game awareness."

The 25-year-old, who was named captain of the Pakistan T20 team ahead of the Australia series in October last year, was recently handed the reins of ODI team as well.

"Making him the T20 captain was a tester. We wanted to see how he will respond to this challenge. All of us agree that he has done a very good job and his biggest plus is that being among the worlds top players he leads by example," Misbah said.

"If you are a performer like Babar then it becomes easier for you to motivate the rest of the team and get things done.

"Even when I was made captain in 2010 my performances were here and there and I was in and out. But captaincy changed my game and mindset and I became a more hard-working and motivated cricketer."

Misbah said Babar always challenges himself and would get better as a captain with experience.

"He is in a zone of his own. He just doesn't want to be in the team. He just doesn't want to play for money. He wants to be the top performer for Pakistan. He is always pitting himself against other top batsmen like Kohli or Smith," he said.

"He loves challenges in the nets and on the field. He has really matured as a player and in time he will get better as a captain with experience."

Babar was the leading run-scorer of the T20I series against Australia last year. He also scored 210 runs, which included a hundred, at 52.50 in the Test series against the same opponents.

In the two-Test home series against Sri Lanka, Babar ended the series with 262 runs with an average of exactly 262.

Misbah feels Babar had changed as a batsman when he got runs in the Tests in Australia.

"Before that he was getting runs in tests but not consistently. In Australia and in the following tests against Sri Lanka and Bangladesh he changed," he said.

Talking about his experience as a head coach, Misbah said: "Having captained, it has helped me a lot. As captain I had to manage everything and also having played under top coaches ... I have seen closely their work ethics and how they managed things.

"It is a learning process. Having remained captain it is a big advantage for coaching because you know the players and their mood swings. You know which player will respond in a given situation,which player is feeling pressure in a scenario.

Misbah said it is not easy juggling between different roles.

"Most important thing as a coach is mentally and psychologically how you handle a group of players," the former skipper said.

"Sometimes captain and coach is different as you have to take tough decisions. Being chief selector makes it it a bit difficult but I had experience of creating and managing teams, I have been building teams since 2003. Till now it is going well."

Misbah feels in Pakistan cricket there were different parameters for judging foreign and local coaches.

"I don't know why it is like this why do we have different eye for locals and foreigners. Maybe we feel they have something special. It looks like every decision by a foreign coach is right. In contrast we tend to be very critical of local coaches no matter what decision they take," he said.

Berlin, Feb 18: Sachin Tendulkar being lifted on the shoulders of his teammates after their World Cup triumph at home in 2011 has been voted the Laureus best sporting moment in the last 20 years.

With the backing of Indian cricket fans, Tendulkar got the maximum number of votes to emerge winner on Monday.

Tendulkar, competing in his sixth and last World Cup, finally realised his long-term dream when skipper Mahendra Singh Dhoni smacked Sri Lankan pacer Nuwan Kulasekara out of the park for a winning six.

The charged-up Indian cricketers rushed to the ground and soon they lifted Tendulkar on their shoulders and made a lap of honour, a moment etched in the minds of the fans.

Former Australian skipper Steve Waugh handed the trophy to Tendulkar after tennis legend Boris Becker announced the winner at a glittering ceremony.

“It's incredible. The feeling of winning the world cup was beyond what words can express. How many times you get an event happening where there are no mixed opinions. Very rarely the entire country celebrates,” Tendulkar said after receiving the trophy.

“And this is a reminder of how powerful a sport is and what magic it does to our lives. Even now when I watch that it has stayed with me.”

Becker then asked Tendulkar to share the emotions he felt at that time and the Indian legend put in perspective how important it was for him to hold that trophy.

“My journey started in 1983 when I was 10 years old. India had won the World Cup. I did not understand the significance and just because everybody was celebrating, I also joined the party.

“But somewhere I knew something special has happened to the country and I wanted to experience it one day and that's how my journey began.”

“It was the proudest moment of my life, holding that trophy which I chased for 22 years but I never lost hope. I was merely lifting that trophy on behalf of my countrymen.”

The 46-year-old Tendulkar, the highest run-getter in the cricket world, said holding the Laureus trophy has also given him great honour.

He also shared the impact the revolutionary South African leader Nelson Mandela had on him. He met him when he was just 19 years old.

“His hardship did not affect his leadership. Out of many messages he left, the most important I felt was that sport has got the power to unite everyone.

"Today, sitting in this room with so many athletes, some of them did not have everything but they made the best of everything they had. I thank them for inspiring youngsters to pick a sport of their choice and chase their dreams. This trophy belongs to all of us, it's not just about me.”

In a tweet on Tuesday, Tendulkar dedicated the award to his country, teammates and fans.

"Thank you all for the overwhelming love and support! I dedicate this @LaureusSport award to India, all my teammates, fans and well wishers in India and across the world who have always supported Indian cricket," he tweeted.

Melbourne, May 1: Reclaiming the top spot in Test cricket has brought smiles back on their faces but Australia coach Justin Langer says beating India in their own den remains the ultimate test and their numero uno status will be put to test when they clash with the Virat Kohli-led team.

After a tumultuous transition phase post the ball-tampering scandal, Australia on Friday displaced India as number one side in Test format but Langer is aware that it does not take long for the situation to change.

"We recognise how fluid these rankings are, but at this time it was certainly nice to put a smile on our faces," Langer told Cricket Australia website. "We've got lots of work to do to get to be the team that we want to be, but hopefully over the last couple of years not only have we performed well on the field, but also off the field," Langer added.

The former left-handed opener underlined what he felt will be the ultimate test of character.

"Certainly a goal for us has been the World Test Championship ... but ultimately, we have to beat India in India and we've got to beat them when they come back (to Australia).

"You can only judge yourself as being the best if you beat the best and we've got some really tough opposition to come," Langer put his priorities in place. The team he insists needs to get better as now others will come gunning for them.

"Getting to No.1 is a great thing, but when you're No.1, you're always the hunted," Langer said. "We've been the hunters for a while, now we're the hunted and we need to get better and better."

Langer also hoped that white ball team under Aaron Finch will win the World Cup. "I know how hard it is to win World Cups ... everything has to go right. One day, I'd love to see Aaron Finch with all his mates lift that T20 World Cup above his head."
