The golden decade – next stop Vancouver 2010

It’s all downhill from here

After the worst winter for 47 years, the snow has finally gone.  I miss it already and now I’m looking forward to virtual winter  from the comfort of my armchair courtesy of the BBC and the 2010 Vancouver Winter Olympics.  Britain is not best suited for winter sports since we only get decent conditions once in every blue moon. GB have only gained 15 medals in the history of the Winter Olympics but we do seem to be getting better with 9 of them in the last 4 decades compared to 6 in the first four.  Our best ever performance was a gold, a silver and a bronze way back in 1936 in Garmisch-Partenkirchen.

So, not a record to worry the likes of Canada, USA and Germany then; countries in which budding Olympians can ski before they can walk.  How can we possibly hope to compete and even get close to our best ever result of 3 medals?

Interestingly, many of the sports at the Winter Olympics involve sliding from the top to the bottom of a hill in some fashion; on skis, a snowboard, in a bobsleigh, on a luge or on a skeleton bob.  The latter usually provokes the cliched ‘skeleton bob, who’s he?’ Most commentators describe skeleton bobsleigh as sliding head first down a hill on a tea tray (‘sliders’ grimace politely if you say this) making it one of the more dangerous Olympic sports (Figure 2).

The potential to win

Siding sports such as skeleton involve converting potential energy to kinetic energy via a 50 m sprint start.  Once the athlete is on the sled gravity takes over to propel them down the slope with the least energy loss.  Any touch on the side or with the feet can shave off hundredths of a second which are all it often takes to differentiate between gold and silver.

Bobsled designers use exactly the same technologies used in cycling, Formula 1 and other technical sports; engineering design using wind tunnels and computational fluid dynamics (Figure 3).  The ruling body of the sport (FIBT) is pretty clear on what you can and can’t do with strict rules on runners and the shape of the sled so not all innovations are allowable no matter how good they are.

Predictions for GB in Vancouver 2010

Of course all technological improvements are confidential so you’ll have to wait until 18th to 20th February if you’re that way inclined.  And how will we do?  GB’s golden couple in skeleton, Shelley Rudman and Kristan Bromley, have timed their recent performances perfectly with good results in the World Cup at St Moritz, finishing the season 2nd and 6th respectively in the World rankings.  Amy Williams finished 5th in the World rankings and has a big chance of a medal while Gillian Cooke and Nicola Minichiello as current world champions in the 2-women bobsled are sure to attract the attention of their competitors.

Predictions are fraught with danger, particularly with the likes of Canada’s Mellisa Holingsworth in fantastic form.  Mind you, the Canadians have apparently never won a gold medal at a home Olympics, so my (educated?) guess is? – I think we’ll do at least as well as our best medal count of 3 in 1936.

Maybe.

About stevehaake

Steve did a first degree in Physics at the University of Leeds before landing two job offers: the first with BT turned out to be in a porta-cabin in the middle of a marsh, while the second was supposed to be image processing but was really smart-bomb design. This left a third option – a PhD in the mechanics of golf ball impacts on golf greens for a person who’d never hit a golf ball. It was a simple choice (the PhD if you didn’t guess) which led 25 years later to being head of a research team of 30-40 looking into similarly unlikely topics. Highlights of the career so far? The early years setting up the ISEA with the likes of Steve Mather, Ron Thompson, Clive Grant and Ron Morgan; the fact that the 1st International Conference on Sports Engineering in Sheffield in 1996 didn’t also turn out to be the last; and getting out the first issue of the first journal on Sports Engineering in 1998. The absolute high point, though, was being in the British Club in Singapore as a guest of the High Commission when the bid for the 2012 Olympics was announced. This has led to the team delivering projects with Olympic athletes that every scientist with a love of sport can only dream of. Steve is now a Senior Media Fellow funded by the EPSRC to encourage the public to engage in science, particularly in the lead up to the London 2012 Olympic Games.

  1. I know, so exciting that they’ve finllay arrived! What draws you to watch them? Any favorite Olympics memories? Any striking memories in general?I’m still waiting to watch the Opening ceremonies tape delay! But I’m in the same time zone!
