I think this is a very exciting time for the sport of swimming for we are seeing swim technique "dogma" or "religious beliefs" about how a person is "suppose" to swim completely throw out the window and strokes are now evolving designed to match a particular person's body-type and/or physical abilities.
Libby [Trickett] is experimenting with her freestyle and she is liking what she is feeling. From the Sydney Morning Herald:
"... Showing a new straight-armed freestyle action, very similar to that of Sullivan and fellow training partner Andrew Lauterstein and a style rare in women's swimming, Trickett - who is currently in solid training - produced an impressive 53.81 seconds swim to comfortably win the 100-metres freestyle last night.
"It's one of the changes that 'Stolly' and I have made to my technique, and I'm really enjoying it, and so far I think it's been quite beneficial," Trickett said.
"It keeps my rhythm a lot better, it has changed my head position, as well as a bunch of other things. It feels strong and you have to be a certain type of athlete to get used to it, but so far so good and it's all been positive signs for me. I'm really happy with that swim. ..."
