Distance Per Stroke And Stroke Rate
Distance Per Stroke ( DPS) And Stroke Rate ( tempo) are swimmings balancing
act. Both are equaly important for faster swimming.
Here are two comparasins of freestylers who have been traineing DPS, for years.
I had just started with some tempo trainging and wanted to see where they were
at. I timed them for 50 yards freestyle on 3 min.sprints.
Swimmer A stats
1st time 29.71 tempo 1.50, 2.55 yards per stroke
2nd time 29.05 tempo 1.35, 2.30 YPS
3rd time 29.15 tempo 1.15, 2.35 YPS
4th time 29.35 tempo 1.28, 2.35 YPS
Swimmer B stats
1st time 23.70 tempo .99, 1.94 yards per stroke
2nd time 24.29 tempo 1.12, 2.34 YPS
3rd time 24.42 tempo .98, 1.99 YPS
4th time 24.16 tempo 1.16, 2.23 YPS
Look at the best time for each swimmer.
Is the yards per stroke length the longest?
Is the tempo the Fastest?
The data was collected using a program called Swim Coach on a Palm.

Looking closely at the Competition Analysis it appears that six factors are
crucial to swimming successfully.
Step 1: LONG STROKES At maximum speed, world class male and female freestyle
swimmers are able to cover a distance of approximately 2 meters per stroke
cycle. (two meters per stroke cycle at a speed of 2 meters per second)
Step 2: Long strokes and FAST STROKES The top freestyle swimmers in the world
are able to complete around 50 stroke cycles per minute at top speed, while
maintaining approximately 2 meters per stroke cycle.
(that's 2.3 yards at 1.2 Per Stroke Cycle)
