Any discussion about adding a new category to your online workouts? Great article in the March-April 2019 Swimmer edition about the success of USPRT. As the writer Jim Thornton wrote: "Perhaps it's time to look into yet another protocol. Masters-USPRT." Perhaps it's time to add it to your online workout section!!!!!
I mean, I don't know what "CSS" is, but if I'm doing the dimensional analysis right, 14k over 6 hours is like 2:30/100, which seems doable... if so, I commend you on adjusting your goals to more realistic things.
Hey, Jeff!
CSS = Critical Swim Speed and defined as the theoretical swimming speed that can be maintained without exhaustion.
There was a test designed in the early 90s to determine the slope of the regression line related to distance and time. It started as a "time trial" of a 50, 100, 200, and 400M. It was later simplified with two test swims of a 50M (D1) and a 400M (D2). The formula to determine a CSS (with this example) is:
CSS in Meter Per Second: (D2 - D1) / (Time 2 - Time 1)
Studies showed that the CSS was equivalent to 80-85% of the maximum 100M speed and 90-95% of the 400M speed.
There are a few variations.
CSS was shown to correlate with the swimming velocity corresponding to the onset of blood lactate accumulation. It can be used as a pretty descent predictor of events longer than 400M.
