I worked assiduously the first 10 years of my TI practice to reduce my stroke count. At the end of that time, my stroke was impressively long - I managed to cross a 50m pool in 26 strokes one time; my SPL in 25y pools was typically 10 to But it gradually dawned on me that I'd focused so intently on lowering my SPL that I had really slowed my rate to do so.
The result was that I had a bit of a "rut" in my nervous system, unable to get comfortable at rates of 1. Consequently I wasn't swimming very fast. But I could go long. I swam the Over the last 4 to 8 years my emphasis has been far more on improving my pace. During much of that time I've used the Tempo Trainer quite a bit, and gradually became quite comfortable with tempos as fast as. Consequently my average SPL in a 25 yd pool is now However, over the next 3 months I plan to work on improving my efficiency at all speeds and distances by one SPL in a 25y pool.
So your stroke count can go down, then you might choose to let it rise again. And then go the other way. It keeps life interesting and your neural circuits on the cutting edge. My TI Story. Stroke rate - Shinji. Just had my daily watch or, rather, marvel at the Shinji video and prompted by a post in another thread, counted the strokes.
Can people confirm that Shinji does a 25 yard length in 12 strokes, taking 20 seconds, according to the timer on the video? By my reckoning that's a stroke rate of around 1. I struggle with anything above 1. Next session I'm gong to slow down the tempo from 1. To the best of my knowledge, in the videos on youtube, Shinji is swimming in a 25m pool. In one of the answers to a viewer's question he stated that he normally swims in a 20m pool, but that in that particular video he was in a 25m pool.
Of course he also swims in the US and may well swim in 25 yard pools there, because most of the US seems to be still swimming yards. Then hold the same arm at your side and have a friend mark the position on the wall. The distance between the two marks is your reach. To measure your streamline length, get into the tallest streamlined position you can while standing against a wall, which includes pointing your toes, and measure how high your fingertips reach above the ground.
Now you can figure out what percent efficiency would be for each stroke, based on your reach and streamline length. Take the distance of the pool and subtract how far from the wall your feet surfaced and add your streamline length. Take that number and divide it by the length of your stroke for a stroke or cycle count.
Instead, they would enter and exit the water at the same place as your body travels through the water. If your hands travel back toward your feet and exit the water closer to the wall you pushed off of, your hands are slipping through the water and not holding it very well.
The length of your stroke in backstroke and freestyle should be equal to the length of your reach. In butterfly, you want your hands to enter and exit the water in the same place as you pull yourself forward with each stroke. There are lots of other ways to use DPS and SR to check how you are doing, including comparing the counts day to day or race to race. It can indicate fatigue, stroke flaws, or improvement.
