Boo mentioned the the chlorine Ions will cause some sort of short circuit at the level III school. I would love to see that research…flojo did extensive pool workouts AFTER her hamstring injury and the rest is history. I would use pool workouts no more then 3 times a week since the environment can transfer some of the wrong messages to the nervous system.
We had access to a pool in Tampa since the weather could allow for outdoor training year round. As for here in Boston the swim coaches (I am one myself) treat track athletes like lepers. This morning we did some light drills and tempo work, but I would have replaced it with some pool conditioning to unload the body.
Pool work…
I find that HR and RPE (screw the borg scales) is far better then goal times. I agree with Mikes protocols….great stuff and very accurate. I would add the point that any addition to a program is a risk since pool work can overload the calf and flexors of the hip. SLOGGERS, invented by Dr. Beasly from the University of South Florida are like giant foam sandals similar to the aqua jogger products. I would use that product (some schools lend equipment out) for low intensity work only and go natural with higher speeds.
I found that replacing tempo work during indoors ( with locations that have snowfall) is very dangerous. I would do one tempo conditioning session for 100m people one time followed by one low intensity recovery session. 400m athletes can do two sessions or more but jumpers and pure sprinter be carefull to the problems that Mike points out. Linda Huey has a nice book one what she does.
