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, Jan 12: Flamboyant India all-rounder Hardik Pandya was on Saturday pulled out of the India A team's tour of New Zealand after he failed mandatory fitness tests in Mumbai.

The selectors had picked him in the squad without testing him in the Ranji games.

Tamil Nadu captain Vijay Shankar has been drafted into the India A team and he has already boarded the flight to New Zealand where they will play two 50-over warm-up games, three List A games and two four-day 'Tests' against the home A team.

It has been learnt that Pandya failed a couple of mandatory fitness tests and his scores were well below the permissible range suggesting that he is far from being fit for international cricket. In this situation, pulling him out of the India A squad was expected.

London, Mar 21: The England and Wales Cricket Board (ECB) has suspended all professional cricket till May 28, delaying the start of the new season, due to the COVID-19 pandemic.

The ECB took the decision following discussions with the First-Class Counties, the Marylebone Cricket Club (MCC) and the Professional Cricketers' Association (PCA).

"It was agreed that, given the current information available, a seven-week delay to the start of the season is the most appropriate approach," an ECB media statement said.

The Board also announced that it is working on three new options, including the three-Test series against West Indies, the T20 Cup and the women's schedule against India, for a possible start in June, July or August.

"Close liaison with the Government will continue, with discussions on the potential of starting the season behind closed doors and giving sports fans the opportunity to live broadcast action," the statement said on Friday.

"The potential for reduced versions of competitions, should the season become further truncated, will also be discussed."

The ECB said it will meet as needed to review the position and make further decisions as the UK situation unfolds.

"During this period of deep uncertainty it is the ECB’s first priority to protect the wellbeing of everyone within the cricket family, from players, to fans and colleagues across the game,’’ ECB Chief Executive Officer Tom Harrison said.

"The decision to delay the start of the season has been essential, given the circumstances the nation faces. I am reassured by the collaborative effort from across the game that together, we will make the very best of whatever length of season we are able to safely schedule in the coming months," he added.

He said this would give the ECB time to keep pace with a fast-moving situation and continue to plan for how a revised season might look.

"Critically, we can also remain as flexible and adaptable as possible, within the obvious restrictions we face."

Last week, England's tour of Sri Lanka was called off mid tournament in view of the rising threat of the pandemic.

"Securing the future of the game will be a primary focus as we plot a revised schedule with an emphasis on the most financially important forms of the game for the counties across international and domestic cricket," Harrison said.

The COVID-19 global death toll has climbed past 11,000 with more than 250,000 infected. In UK, close to 4000 have tested positive so far and 177 died.

New Delhi, Apr 8: Former Pakistan pacer Shoaib Akhtar on Wednesday proposed a three-match ODI series against arch-rivals India to raise funds for the fight against the Covid19 pandemic in both the countries.

The two nations have not played a full-series since 2007 due to the terrorist attacks on India by Pakistan-based outfits and the resultant diplomatic tension. They only play each other in ICC events and Asia Cup.

"In this time of crisis, I want to propose a three-match series in which for the first time, the people of neither country would be upset at the outcome of the games," Akhtar told PTI from Islamabad.

"If Virat (Kohli) scores a hundred, we will be happy, if Babar Azam scores a hundred, you will be happy. Both teams will be winners irrespective of whatever happens on the field," he said.

"You are bound to get massive viewership for the games. For the first time, both countries will play for each other. And whatever funds are generated through this can be donated equally to the government of India and Pakistan to fight this pandemic," added the 44-year-old.

No idea of logistics

With both countries in a lockdown amid the fast-spreading pandemic, the games can only be organised when things improve. However, Akhtar feels the sooner they are held, the better it would be but could not tell how the logistics of such an initiative would be worked out.

"Everyone is sitting at home at the moment, so there will be a massive following for the games. May be not now, when things start improving, the games could be organised at a neutral location like Dubai. Chartered flights could be arranged and the matches could he held.

"The whole world will tune into it, so much money can be raised to deal with this crisis. In difficult times, the character of the nation comes forward."

Start of a new era?

"It could even lead to resumption of bilateral cricketing ties and relations of both countries improve diplomatically. You never know," said the 'Rawalpindi Express'.

In these extraordinary times, Akhtar feels both countries should help each other. "We can only propose the matches. The rest is up to the authorities (to decide)."

India cricketers Yuvraj Singh and Harbhajan Singh were recently trolled for asking their social media followers to donate to Shahid Afridi's charity foundation which is doing its bit in Pakistan's fight against the deadly virus.

"It was inhuman to criticise them. It is not about countries or religion at the moment, it is about humanity," he opined.

India memories

Akhtar has spent a lot of time in India as a commentator. He fondly recalled his days in Mumbai during the World T20 in 2016, the last time he came to India for work.

"I am forever grateful about the love I have received from the people of India. For the first time I am revealing this, whatever I used to earn from India, I made a significant amount there, thirty percent of it, I used to distribute among the low income staff who used to work with me in the TV," he remembered.

Akhtar used to visit the city's slum areas with his face covered to hand out financial help to elder women there.

"From drivers, runners to my security guys. I took care of a lot of people. I was like if am earning from this country, I have to help my colleagues also.

"I also remember visiting slums of Dharavi and Sion in the wee hours to meet people I worked with," added Akhtar.
