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.

London, Apr 12: Former Formula 1 legendary driver Stirling Moss died at the age of 90 on Sunday.

"All at F1 send our heartfelt condolences to Lady Susie and Sir Stirling's family and friends," Formula 1 said in a statement.

Often referred to as the greatest driver never to win the world championship, Moss contested 66 Grands Prix from 1951 to 1961, driving for the likes of Vanwall, Maserati and Mercedes, where he famously formed a contented and ruthlessly effective partnership with lead driver Juan Manuel Fangio.

In his 10-year-long stint at the tracks, Moss took 16 wins, some of which rank among the truly iconic drives in the sport's history - his 1961 victories in Monaco and Germany in particular often held up as all-time classics.

Moss won the 1955 Mille Miglia on public roads for Mercedes at an average speed of close to 100mph, while he also competed in rallies and land-speed attempts.

Following an enforced retirement from racing (barring a brief comeback in saloon cars in the 1980s) after a major crash at Goodwood in 1962, Moss maintained a presence in Formula 1 as both a sports correspondent and an interested observer, before retiring from public life in January of 2018.

Dubai, Jul 19: On hold for the past two months, the fate of this year's T20 World Cup will be up for a decisive round of deliberation when the ICC board meets virtually on Monday with the BCCI hoping for a postponement to ensure that the IPL can go ahead.

The global event is supposed to be held from October 18 to November 15 in Australia but the country's cricket board had, in May itself, expressed its inability to host amid a second surge of Covid-19 cases in the state of Victoria.

With India's case load also exceeding the 10 lakh mark, including more than 26,000 deaths, the IPL, if it is held, is likely to move to the UAE once the central government gives its go ahead.

"The first step was postponement of Asia Cup, which has happened. We can only start to move ahead with our plans after the ICC announces the postponement. They have been sitting on the decision even after Cricket Australia said that they are not too keen on hosting the event," a BCCI Apex Council member told PTI on conditions of anonymity.

This year's T20 World Cup will likely be held in Australia in 2022 as India doesn't want to swap its 2021 hosting rights with Cricket Australia as of now.

That Australia won't be hosting the mega event was clear after the cricket board told its players to prepare for a white-ball series against England scheduled for late September.

CA has even announced a 26-strong preliminary squad for that tour.

The ICC, on its part, has maintained that it wants to explore all possible "contingency" options before taking a call of such immense magnitude. And it is not unusual for the governing body to wait this long.

"Pakistan was supposed to host the Champions Trophy in 2009. After the terrorist attacks on the Sri Lankan team bus, everyone in their proper senses knew that PCB will never host a big event in distant future," said a source familiar with the functioning of the ICC.

"Yet, ICC deputed its employees in Pakistan for months when South Africa was already preparing to host the event. Everyone knew but a formal announcement of shift took months as threat assessment was part of protocol.

"The ICC couldn't have just postponed 9the T20 World Cup) immediately as initially, the top ministers of the Australian government expressed keenness to host," he added.

The Pakistan Cricket Board has also resigned itself to this outcome after vehemently opposing the Indian board.

The postponement of Asia Cup, which was supposed to be hosted by the PCB, to 2021 was a big blow to Ehsan Mani and his team.

"We have had a lot of discussions and the feeling is it (T20 World Cup) would not be possible this year. ICC has World Cups lined up in 2021 and 2023 so we have a gap year where we can adjust this event," Mani had recently said while talking to reporters in his country.

It has been learnt that PCB is contacting other boards in the hope of finalising some bilateral engagements as the national team has nothing lined up after its England tour.

Nomination process for Chairman's election:

The other issue that is likely to come up for discussion in Monday's meeting is the nomination process for the next independent chairman of the ICC after Shashank Manohar's resignation earlier this month.

It is learnt that there is no consensus on what should be the criteria in case multiple candidates join the fray.

"The board is not united on whether the usual 2/3rd majority to decide will be used (as its in case of policy decision) or the case of simple majority among the 17 board members," an ICC Board member said.

England and Wales Cricket Board's Colin Graves was considered the top contender with BCCI president Sourav Ganguly's name also being floated.

Ganguly's candidature will certainly depend on whether the Supreme Court waives off the cooling off period and allows him to continue as BCCI president beyond July 27 when he completes six years as an office-bearer in the Indian Board's state and national units.

When asked about the possibility of taking up the ICC job in a recent interview, the 48-year-old said he is young and and in no hurry for the position.

New Zealand's Gregor Barclay, Hong Kong's Imran Khawaja, who is currently the interim chairman, are also being talked about as potential candidates.

New Delhi, Apr 12: As devotees across the world celebrate Easter today, former Sri Lanka skipper and current Marylebone Cricket Club (MCC) president Kumar Sangakkara on Sunday condoled the demise of people who lost their lives during last year's Easter Sunday bombings in Sri Lanka and said someone must seek answers to the questions which still remain unresolved.

"A year on we all share the pain of the families grieving lives lost, we stand with you and for you. We remember. So many questions still unanswered, but answer them someone must," Sangakkara tweeted.

On April 21, 2019, multiple blasts ripped through Sri Lanka when the Christian community was celebrating Easter Sunday.
The explosions rattled churches and high-end hotels across the country, killing 258 people and injuring over 500.

A local terror group called National Thowheeth Jama'ath had claimed responsibility for the devastating attacks.

The island nation was put under a state of emergency for a period of four months from April to August.

The Sri Lankan police had then said that 293 suspects were arrested in connection with the Easter Sunday bombings in the island country in April.

This year, most of the devotees would be offering the prayers from their homes as mass gatherings have been suspended in most countries due to the ongoing coronavirus pandemic.

Easter marks the resurrection of Jesus Christ following his crucifixion on Good Friday. It also marks the culmination of Lent, a 40-day period of fasting and penance.
