ASR Sprint Training for swimmers?

I think that paper is only about predicting times across a range of distances from two measurements. Not really about a training method. The training method mentioned in the 3rd link is similar to USRPT with doing repeats until failing to hit a goal time, but with a lot more rest and no failures allowed. They use the prediction method from the paper to find goal times for various distances to use in practice. It seems like the ASR link I found from your 3rd link doesn't explain their program or have their online calculator anymore so I can't see if you are supposed to reduce the goal time off your peak speed for that distance (As the predicted time is your fastest time for that distance, not a race pace like USRPT). Ideally the anerobic time should be a very short interval but I made the spreadsheet and tested with various 50, 100, and 200m times from meets. Although the calculated aerobic speed seemed way too slow, I found putting in my 50 and 200m times in back and free predicted my 100m times within 1 second. Putting in 50 and 100m times predicted my 200m times within 1-2 seconds. It seems like you can use the spreadsheet for swimming and predict how fast swimmers could do a 25 or 75 etc, or race they have never swum. You could also use it for setting goal times for 95/90/85% etc. effort swims for any distance.

Thanks Arthur, You are correct, info on target times is hard to come by. I just go by feel. ASR is simpler than USRPT in that it is always max speed. The track people are running 10 and 20 m sprints x 10 which translates into very short pool yardages. Here is a good interval training overview paper that has a little ASR info: esthermorencos.files.wordpress.com/.../buchheit-2013-high-intensity-interval-training-solutions-to-the-programming-puzzle.pdf If anybody has part II, I'd appreciate a copy.

The track people are running 10 and 20 m sprints x 10 which translates into very short pool yardages. It takes track sprinters well over 30m to reach top speed, and Bolt probably twice that distance

It takes track sprinters well over 30m to reach top speed, and Bolt probably twice that distance Correct, that is why they use a run in or flying start. We, swimmers have the opposite source of error in that we start faster than we swim. Although the difference in speed between a wall push start and all out sprinting might be small enough to ignore.

Here's some more T&F ASR stuff, this by a timer company that sells stuff for odd distance timing. I don't understand all the noise about energy systems not mattering, but for your information here it is: itccca.com/.../ITCCCA-Clinic-ASR-Training-and-Freelap-PART-I-.pdf Here is a good criticism of ASR and fad training systems: www.scienceofrunning.com/.../how-to-spot-bad-science-and-fads.html

Not exactly related but I had a positive result training for a 1.5 mile run USRP style, and at a pace much faster than I would do the timed run. I ran just once or twice a week, 3 months out leading up to it logging no more than 30 miles total training. I hit the time I had over 20 years ago .

Other than Rushall, Track seems to be where the energy is. (bad pun)!
