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, Feb 14: Former Sri Lanka skipper and current Marylebone Cricket Club's president Kumar Sangakkara has said that the 2009 Lahore terror attack taught him about his own character and values.

His remarks came as MCC arrived in Pakistan to play T20I matches against Lahore Qalandars. This will mark his first return to the Gaddafi Stadium, where a shocking atrocity took place when the Sri Lankan bus was attacked by terrorists.

The Sri Lankan team was on their way to Lahore's Gaddafi Stadium for a Test match with Pakistan in 2009 when terrorists from the Taliban and Lashkar-e-Jhangvi (LeJ) fired indiscriminately at their bus. The attack left eight people dead and injured seven Sri Lankan players and staff.

Ever since the incident, no cricket team toured Pakistan to play a cricket series, however, the landscape changed last year as Sri Lanka paid a visit to the country to play a series across formats. After that, even Bangladesh toured Pakistan and now there are talks of South Africa going to the country to play a series.

"I don't think I need any flashbacks, because I remember that day and those moments so very clearly. It's not something I relive or wallow in. But it's an experience you should never forget, because it gives you perspective in terms of life and sport, and you learn a lot about your own values and characters, and those of others," ESPN Cricinfo quoted Sangakkara as saying.

"I have no reservations about talking about it, it's not something that upsets me, but these sorts of experiences can only strengthen you. Today I consider myself very fortunate to be able to come back here to Lahore, and at the same time remember the sacrifice of all those who lost their lives that day," he added.

Sangakkara said that every human has his own way of dealing with such adversity.

"I think everyone deals with it in their own personal way. But at the same time, what really unites us is that you face adversity and you face challenges, and you have to get past it, and you've got to do that successfully. It's about moving forwards and upwards and being part of cricket. Being Sri Lankan you learn those lessons quite well, because, throughout our civil war, cricket was a unique vibe," Sangakkara said.

"We speak about the attack at various times. We even have a laugh about it, in terms of what we went through because it helps sometimes to look at it with a bit of humour, even though there was a tragic loss of life, and other serious injuries within that incident," he added.

MCC in the weeklong tour will take on Lahore Qalandars in a T20 match at the Gaddafi Stadium later today.

Kumar Sangakkara will lead the MCC's twelve-man squad for the tour, which includes Ravi Bopara, Roelof van der Merwe, Ross Whiteley among others.

Fixtures for the upcoming tour are as follows:

MCC vs Lahore Qalandars, T20I, Gaddafi Stadium, February 14

MCC vs Pakistan Shaheens, ODI, Aitchison College, February 16

MCC vs Northern, Aitchison College, T20I, February 17

MCC vs Multan Sultans, Aitchison College, T20I, February 19.

Srinagar, Jan 10: Real Kashmir FC made a strong comeback in the second half to play out a 1-1 draw against former champions Punjab FC in their home I-League match here on Friday.

The 'Snow Leopards' equalised in the 62nd minute through Gnohere Krizo in front of a partisan crowd of 8,500 spectators after Makan Chothe had given Punjab FC the lead in the 21st minute at the TRC ground.

After Thursday's draw, Punjab FC is placed third on the table with 10 points from seven games. Real Kashmir FC remained at eighth with six points from five matches. This was Real Kashmir's third home match on the trot.

The match was a story of two halves as the first belonged to the visitors who enjoyed a 62 per cent possession of the ball, whereas the second belonged to the home side.

Both the teams were looking to gain an early advantage and Punjab FC took the lead after 21 minutes.

Confusion inside the Real Kashmir box because of a long ball from Punjab opened up an opportunity for Chothe and he made no mistake as he smashed the ball at the back of the net.

As the fans cheered on, Real Kashmir created a flurry of chances, but none of the home side players could find the back of the net. Punjab was able to hold on to their slender lead heading into the tunnel.

The second half resumed with Real Kashmir pressing high up the field and pressurising Punjab.

In the 56th minute, Real Kashmir playmaker Kallum Higginbotham cut through two defenders on the left side of the box and the ball fell to Mason Robertson, whose shot was too weak to trouble the Punjab goalkeeper.

Soon after, it was Danish Farooq who tried a curler from a distance but his shot did not have enough bend to trouble the Punjab goalkeeper. The home team's effort finally paid off in the 62nd minute.

A miscalculated header by Danilo Augusto fell at the feet of Gnohere Krizo, who was one-on-one with the keeper. He made no mistake in striking the ball into the opponent's goal to score the equaliser.

Real Kashmir was in their groove now, and Kallum came in from the right with a beautiful low cross across the face of the goal but Mason could not get a touch as the chance went begging.

The duo of Kallum and Mason were proving difficult for Punjab to deal with. In the 82nd minute, a beautiful long ball by Kallum found the head of a towering Mason, but the effort went just over the crossbar.

Within a few moments, Punjab again had another nervous moment as Chesterpoul Lyngdoh's cross from the right side hit the arm of Thoiba Singh but the referee turned down an appeal for penalty.
