How Do I Shift SPL On Command?

Some of you may be able to achieve a decent SPL = N already, without much effort. But it may be that you have a hard time shifting it to N+1 or N-1 on demand. You haven’t actually learned what features of your stroke you can adjust to affect Stroke Length.

Here are some of the primary details you can adjust your stroke to adjust the Stroke Length:

A. Recovery

You can slightly speed up or slightly slow down the recovery swing to affect the length of the stroke.

B. Catch/Hold

You can slightly increase pressure or decrease pressure of the catch to affect the length of the stroke.

C. Mailslot + Catch Moment

You can time the Mailslot moment (for the recovering arm) to happen precisely at the Set-The-Catch moment, or you can make the Catch wait just a micro-second longer, a little more ‘overlap’ in the stroke which allows the Spearing Arm to submerge to the wrist before you set the Catch. This affects the length of the stroke.

D. Spear and Extension

You can extend your arm just 1-2 cm further, opening the armpit just a little more, or stop your extension just 1-2 cm shorter to affect the length of the stroke.

For example, you may work at either 19 and 20 SPL, or 19 and 18 SPL, learning how to switch from one to the other using some of these adjustments above.

PRACTICE EXAMPLE

A practice set may look like this:

800 meters

(For this example let’s assume you will work with 19 and 18 SPL, with N = 19 SPL)

4x (1x 25m holding N SPL, no rest, 1x 25m holding N-1 SPL), with 15 seconds between repeats

Do 4 Rounds of this set, with the Focal Points listed above to adjust your SPL back and forth from N to N-1:

Round #1 use Focal Point A
Round #2 use Focal Point B
Round #3 use Focal Point C
Round #4 use Focal Point D
