Criticism of TI Principles

I've noticed at lot of dicsussion in recent threads about TI principles, As you can see from my location, I'm on the other side of the atlantic and TI has started to make an impact over here. I've come across a lot of people in my local University pool who seem to have been mesmerised by the TI message and it is now common for me to see people swimming on their sides with one outstreached arm and a submerged head. When the time comes to breath these guys have their heads so deep from pressing their bouy that they end up lifting it so high that they loose whatever alignment they had in the first place. From talking to them, none of them seem to want to develop a proper kick and build up endurance so they can develop good form. I have decided to post a list of TI priciples and my own critism of these, feel free to add to the list or post a TI defence! TI PRINCIPLE 1 Side to Side Rotation to get into Low Drag Fish-like Position Criticism Rotation is good to get extentsion and a good catch + power into the stroke, Excessive rotation slows down the stroke. TI PRINCIPLE 2 Swim DownHill Press your Bouy Criticism: Holding head too deep creates drag Makes breathing Difficult TI PRINCIPLE 3 No Kicking Criticism Kicking essential to fast swimming + to maintain good form particularly for male swimmers. TI PRINCIPLE 4 Front Quadrant Swimming/ Distance per stroke, Criticism A reasonably high Stroke rate is necessay for fast swimming, Unless you have a very strong kick a glide phase in your stroke will cause decelleration TI PRINCIPLE 5 Drills will make you a better swimmer Criticism Drills are important, but there is no substitute for good quality fast training.

    Power is included in the combo (Stroke Length) x (Stroke Rate). If it wasn't, then Speed = (Stroke Legth) x (Stroke Rate) would be false, and it isn't: physics apply to moving objects, physics apply to swimmers for example, and (50 meters free) / (24 seconds) = = speed (in physics) = = x = = (Stroke Length) x (Stroke Rate). All the big races have Stroke Length and Rate in the stats (Jim Montgomery's 1976 100 free in 49.99 has them, Felipe Magnini's 2005 Montreal World Championships 100 free in 48.12 has them, and so on), efficiency and power are not in the stats, power is included in (Stroke Length) x ( Stroke Rate). In physics -not in the street or at the pool, but in physics- where the terms are authentic, power has a rigorous definition (power = mass x acceleration x speed), and efficiency is inexistent.
