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.

May 13: With the Olympics postponed due to the coronavirus, top Japanese fencer Ryo Miyake has swapped his metal mask and foil for a bike and backpack as a Tokyo UberEats deliveryman.

The 29-year-old, who won silver in the team foil at the 2012 London Olympics and was itching to compete in a home Games, says the job keeps him in shape physically and mentally -- and brings in much-needed cash.

"I started this for two reasons -- to save money for travelling (to future competitions) and to keep myself in physical shape," he told AFP.

"I see how much I am earning on the phone, but the number is not just money for me. It's a score to keep me going."

Japanese media have depicted Miyake as a poor amateur struggling to make ends meet but he himself asked for his three corporate sponsorships to be put on hold -- even if that means living off savings.

Like most of the world's top athletes, he is in limbo as the virus forces competitions to be cancelled and plays havoc with training schedules.

"I don't know when I can resume training or when the next tournament will take place. I don't even know if I can keep up my mental condition or motivation for another year," he said.

"No one knows how the qualification process will go. Pretending everything is OK for the competition is simply irresponsible."

In the meantime, he is happy criss-crossing the vast Japanese capital with bike and smartphone, joining a growing legion of Uber delivery staff in demand during the pandemic.

"When I get orders in the hilly Akasaka, Roppongi (downtown) district, it becomes good training," he smiles.

The unprecedented postponement of the Olympics hit Miyake hard, as he was enjoying a purple patch in his career.

After missing out on the Rio 2016 Olympics, Miyake came 13th in last year's World Fencing Championships -- the highest-ranked Japanese fencer at the competition.

The International Olympics Committee has set the new date for the Olympics on July 23, 2021.

But with no vaccine available for the coronavirus that has killed nearly 300,000 worldwide, even that hangs in the balance.

Miyake said the Japanese fencing team heard about the postponement the day after arriving in the United States for one of the final Olympic qualifying events.

With his diary suddenly free of training and competition, he said he spent the month of April agonising over what to do before hitting on the Uber idea.

"Sports and culture inevitably come second when people have to survive a crisis," he said.

"Is the Olympics really needed in the first place? Then what do I live for if not for the sport? That is what I kept thinking."

However, the new and temporary career delivering food in Tokyo has given the fencer a new drive to succeed.

"The most immediate objective for me is to be able to start training smoothly" once the emergency is lifted, he said.

"I need to be ready physically and financially for the moment. That is my biggest mission now."

But not all athletes may cope mentally with surviving another "nerve-wracking" pre-Olympic year, he said.

"It's like finally getting to the end of a 42-kilometre marathon and then being told you have to keep going."

As a child, Miyake practised his attacks on every wall of his house -- and he said his passion for the sport was what was driving him now.

"I love fencing. I want to be able to travel for matches and compete in the Olympics. That is the only reason I am doing this."

New Delhi, Jun 25: India spinner Ravichandran Ashwin on Thursday called the 1983 World Cup win as the 'landscape' changing moment for the game of cricket in the country.

Today, India is celebrating the completion of the 37 years of the maiden World Cup triumph under the leadership of Kapil Dev.

"Today 37 years ago, changed the cricketing landscape in India. Thank you @therealkapildev and team for making the game a career for many of us today. Deeply indebted," Ashwin tweeted.

In 1983, in the finals between India and West Indies, the latter won the toss and opted to bowl first.

The Kapil Dev-led side managed to score just 183 runs as Andy Roberts took three wickets while Malcolm Marshall, Michael Holding, and Larry Gomes picked up two wickets each.

Defending 183, India did a good job of keeping a check on the Windies run flow, reducing the side to 57/3.

Soon after, the team from the Caribbean was reduced to 76/6 and India was the favourites from there on to win the title.

Mohinder Amarnath took the final wicket of Michael Holding to give India their first-ever World Cup title win.

In the finals, West Indies was bowled out for 140, and as a result, India won the match by 43 runs.

Kapil Dev lifting the trophy at the balcony of Lord's Cricket Ground still remains an image to savour for all the Indian fans.

In the finals, Mohinder Amarnath was chosen as the Man of the Match as he scored 26 runs with the bat and also picked up three wickets with the ball.

India has been the regular participant in the World Cup from its beginning to the latest edition. The first edition was held in 1975 and from there on, it has taken place after a span of every four years.

West Indies won the first two World Cup titles (1975, 1979) and was the runner-up in 1983. India has won the title two times, in 1983 and in 2011.

MS Dhoni captained the 2011 team to win their second title after 28 years. Australia has won the tournament five times (1987, 1999, 2003, 2007, and 2015).

May 14: Veteran South Africa batsman Faf du Plessis has proposed a two-week isolation period for players before and after the T20 World Cup as a way to stage the event as per schedule later this year.

Like other sports, cricketing action too has come to a complete halt due to the coronavirus pandemic. The fate of the T20 World Cup to be held in Australia in October-November is shrouded in uncertainty.

Talking to Bangladesh ODI captain Tamim Iqbal, du Plessis said travel was going to be an issue despite Australia being less affected by the deadly contagion.

"I am not sure... reading that travelling is going to be an issue for lot of countries and they are talking about December or January. Even if Australia is not affected like other countries, to get people from Bangladesh, South Africa or India where there is more danger, obviously it's a health risk to them," du Plessis said.

"But you can go in before the tournament (for) two weeks isolation and then play the tournament and afterwards two weeks isolation," said the former captain.

Several countries across the globe, including South Africa, Australia and India, have travel restrictions in place and the veteran Proteas batsman joked travelling by boat is not an option.

"But I don't know when South Africa will open their travel ban because we can't go there like old days on boats," du Plessis said.

In March, South Africa's ODI series against India was called off after the first match in view of the pandemic.

The coronavirus outbreak, which originated in the Chinese city of Wuhan, has infected more than 44 lakh people worldwide while causing close to 3 lakh deaths.
