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, Mar 5: Cricket's slow geographical expansion is turning out to be a blessing in disguise for the cash-rich Indian Premier League (IPL) which looks set to beat the dreaded novel coronavirus threat and go ahead as scheduled.

At a time when the number of recorded deaths because of the deadly outbreak across the globe is touching 3500 with a plethora of international sporting events getting cancelled, the IPL seems to be in a parallel universe where "all is well".

And there are multiple practical reasons why the T20 extravaganza will be held as per schedule. A major reason is the small number of countries that play the game and an even smaller fraction of overseas players, who will compete in the world's richest cricket league starting March 29 in Mumbai.

Till Thursday, the reported number of positive COVID-19 cases in India stood at 29, including 16 Italian tourists. However, none of the overseas recruits of eight IPL franchises have expressed any apprehensions about travelling to India.

Just over 60 players from cricket nations such as Australia, England, New Zealand, South Africa and the Caribbean islands comprise the elite foreign brigade and the reported positive cases of coronavirus in all these countries is next to none.

"The IOC is saying Olympics in Tokyo will be held as per schedule. In comparison, IPL is a minuscule tournament. If Olympics can be held, there's no reason why IPL can't be held," a BCCI official told PTI on conditions of anonymity.

STAR SPORTS FACTOR

The second and perhaps the biggest reason is broadcasters. Star Sports has bought the rights for Rs 16,347 crore (USD 2.55 billion) for a period of five years and their advertising revenues will take a huge hit if the tournament doesnt go ahead as planned. Former Delhi Daredevils CEO Hemant Dua explained the economics. "Look Star as well as BCCI has got everything insured. I don't know if there is any specific insurance cover for cancellation due to coronavirus but there is no chance of that happening if I read the situation properly," Dua told PTI.

GOVERNMENT GUIDELINES

The BCCI is also depending on the guidelines given by the government with regards to dealing with the health crisis.  "Every person availing international flights will be screened for coronavirus at the port of entry. That is the biggest health security measure. Obviously the BCCI will strictly adhere to any health advisory that government will issue," a Board official said.

But since there is an advisory that social gatherings are inadvisable at this point, won't it affect the league? "You will only come to know once the ticket sales start. If the stadiums are packed, that means people are coming but if stands are largely empty, then you can presume that people are wary.

Jun 18: Sri Lanka "sold" the 2011 World Cup final to India, the country's former sports minister said on Thursday, reviving one of cricket's most explosive match-fixing controversies. Mahindananda Aluthgamage, who was sports minister at the time, is the second senior figure to allege the final was fixed, after 1996 World Cup-winning skipper Arjuna Ranatunga. "I tell you today that we sold the 2011 World Cup finals," Aluthgamage told Sirasa TV. "Even when I was sports minister I believed this."

Aluthgamage, sports minister from 2010 to 2015 and now state minister for renewable energy and power, said he "did not want to disclose" the plot at the time.

"In 2011, we were to win, but we sold the match. I feel I can talk about it now. I am not connecting players, but some sections were involved," he said.

Sri Lanka lost the match at Mumbai's Wankhede stadium by six wickets. Indian players have strongly denied any wrongdoing.

Ranatunga, who was at the stadium as a commentator, has previously called for an investigation into the defeat.

"When we lost, I was distressed and I had a doubt," he said in July 2017. "We must investigate what happened to Sri Lanka at the 2011 World Cup final."

"I cannot reveal everything now, but one day I will. There must be an inquiry," added Ranatunga, who said players could not hide the "dirt".

Sri Lanka batted first and scored 274-6 off 50 overs. They appeared in a commanding position when Indian superstar Sachin Tendulkar was out for 18.

But India turned the game dramatically, thanks partly to poor fielding and bowling by Sri Lanka, who were led by Kumar Sangakkara.

Sri Lankan cricket has regularly been involved in corruption controversies, including claims of match-fixing ahead of a 2018 Test against England.

Earlier this month, the Sri Lankan cricket board said the International Cricket Council was investigating three unnamed former players over alleged corruption.

Sri Lanka introduced tough penalties for match-fixing and tightened sports betting restrictions in November in a bid to stamp out graft.

Another former sports minister, Harin Fernando, has said Sri Lankan cricket was riddled with graft "from top to bottom", and that the ICC considered Sri Lanka one of the world's most corrupt nations.

Former Sri Lankan fast bowler Dilhara Lokuhettige was suspended in 2018 for corruption relating to a limited-overs league.

He was the third Sri Lankan charged under the ICC anti-corruption code, following former captain and ex-chief selector Sanath Jayasuriya, and former paceman Nuwan Zoysa.

Jayasuriya was found guilty of failing to cooperate with a match-fixing probe and banned for two years. Zoysa was suspended for match-fixing.

New Delhi, Jun 14: From being a 20-year-old mischievous talented striker to 35-year-old, India captain Sunil Chhetri has seen Indian Football through thick and thin. Coaches, who have nourished the striker with utmost care to yield the best for the team have seen numerous changes from close quarters but one aspect has remained absolutely perpetual, resolute - Chhetri's never-say-die attitude and 'dedication.'

Igor Stimac, current head coach of the Blue Tigers recalled seeing Chhetri during the preparatory camp ahead of the King's Cup 2019 - his maiden assignment with the Blue Tigers.

The Croatian pointed out that despite being the senior-most member of the troop, "Chhetri craved to push maximum to achieve the result after the heartbreak in AFC Asian Cup."

"Dedicated, workaholic and team man -- those are some of the attributes which define Sunil Chhetri. When I first saw him last year, they were back to the National Team camp after a long gap following the AFC Asian Cup. A few boys were new but the fire under his belly probably was more than anyone else. That's the secret of his long career. Congratulations!" All India Football Federation (AIFF) quoted Stimac as saying.

Sukhwinder Singh, while reminiscing the India-Pakistan bilateral series in 2005, revealed that he wasn't sure about the youngster's credibility at all.

"I needed someone who had the trickery, didn't have the fear and had to be quick. Honestly, Sunil wasn't in my mind at all. He wasn't my first option. I had my doubts," Sukhwinder, coach during Chhetri's first national team endeavour, recalled.

He had seen the youngster from close quarters while coaching in JCT FC where Chhetri started blossoming and hogging the limelight. Chhetri, who scored more than 20 goals during his 3-season-long stay in JCT, had already shown signs of performing in the bigger stages which convinced Sukhwinder Singh picking him up for the high-octane bilateral series in Pakistan.

"I haven't seen anyone as dedicated as Sunil. I saw him maturing in JCT and there were flashes of what he could do in the future. I still remember his hunger. In 19 years of my coaching career, I haven't seen anyone as dedicated as Sunil. He remained undaunted and was never willing to shy away from working hard. Shouldering the responsibility for 15 years demands discipline and he keeps it above everything else," Sukhwinder maintained.

According to Stimac, Chhetri is someone who always runs the extra yard, breaks some more sweat during the training session which, in the process encourages the youngsters to emulate him. The entire process aids the cumulative progress of the team and raises the bar.

"I see him as someone who always pushes the bar in the training and never compromises with the regime. He drives the team and he is the character who defines the team. Numerous characters have glorified the Indian Football history and he's definitely one of them who have made his country proud," Stimac said.
