In summary, the Start position tended to give the swimmer the following advantages: Quicker reaction time off the block A more horizontal flight curve than traditional starts – [see Intro figure] More velocity throughout the under water dolphin stage All the above resulting in a much faster start [15 metre] time for the 3 swimmers tested. 14 SWIMMING IN AUSTRALIA Photograph courtesy of Delly Carr (Sportshoot) - ASCTA Photographer of the Year She dropped from a 1.05.10 for This footage revealed in graphic Arm Stroke Pattern: the 100 Back at Age 17, down to detail, how the angles mentioned a National Age record of 1.01.81, above affect the catch and pattern Throughout my 24 years in 7 months later at Age 18.

SWIMMING IN AUSTRALIA 15 Photograph courtesy of Swimming Australia Limited Trials Time inin Adelaide Best of the Best chase Swimming's Holy Grail Ian Hanson, who has attended the last seven Olympic Games, provides ASCTA readers with this comprehensive look at the 2012 Australian Olympic Swimming Trials which will put the SA Aquatic and Leisure Centre in Adelaide very much on the international swimming map between March 15 and 22. There will be jubilation and joy; heartache and heartbreak as the cream of Australia’s swimmers put everything on the line, chasing places on Australia’s London Olympic swimming team. It will bring together the best of the best with the new breed of Australia’s swimmers up against some of the sport’s biggest names of the past 15 years. The Trials will be just the start for some and the end for others at a meet like no other, when nerves can sink careers and drive others to greatness in a cut throat eight days of racing. The 40-strong team will be announced on Thursday, March 22 when Olympians of the past join in welcoming the class of 2012 to a very exclusive club. History beckons Leisel Jones who has the opportunity to become the first Australian swimmer to represent at four Olympic Games. She already has an extraordinary Olympic record of three gold, four silver and a bronze and is priming herself to add further medals to her amazing collection. But like everyone else: first she has to make the team and that’s what makes Olympic Swimming Trials as nerve-wracking for coaches and families as they are for swimmers. Here is a comprehensive event-by-event guide to the 2012 Olympic Swimming Trials. March 15-22, SA Aquatic and Leisure Centre, Adelaide 16 SWIMMING IN AUSTRALIA Photograph courtesy of Delly Carr (Sportshoot) ASCTA Photographer of the Year 50m Freestyle A qualifying time: 22.11 Season’s best: Matt Targett (21.98) MMen en Contenders: Matt Targett, Matt Abood, Cameron Prosser, James Magnussen, James Roberts, Eamon Sullivan Outlook: Matt Targett remains the stand out performer going into the Trials after his PB 21.98 at the SA State Championships and only has to repeat that performance to waltz onto his second Olympic team. On his day Abood can pull out a big one and he’ll need to if he wants a place on his first Olympic team. His 22.15 behind Targett in Adelaide was a great indicator that he’s on target. No one else has shown anything this season’s that suggests they can break 22. Australia has never won an Olympic medal in this event since it was introduced in Seoul in 1988 – Maybe 2012 will see an Aussie on the podium. The big question? With the pressure of the Olympic Trials, can Targett and Abood both crack 22? 100m Freestyle Adelaide A qualifying time: 48.82 Best of the Best chase Swimming's Holy Grail Season’s best: James Magnussen (48.05) Contenders: James Magnussen, Matt Targett, James Roberts, Cameron Prosser, Kyle Richardson, Cameron McEvoy, Eamon Sullivan, Matt Abood, Michael Klim, Tommaso D’Orsogna, Ian Thorpe Outlook: On form, Magnussen is close to being the “Black Caviar” of the pool and if anyone wants to beat the world champion then they will have to break 48 and swim faster than they’ve ever swum.
