Serve: Big swingers save shoulders

[gzhpcu]

Hi John,
Thanks for the suggestion to switch back to a big swing. I found this article which mentions another benefit (I assume you are familiar with it):
Serving techniques study

While those with an abbreviated swing recorded a similar service velocity and upper limb torques to those who used a full swing, minor differences were recorded in the force profile at the shoulder...A trend of higher anterior shoulder force and the general trend of forces and torques for both groups would indicate that the full swing may be a preferred service technique from a loading perspective.

I have noticed that my whole serve motion seems more relaxed and fluid...

Excellent! There must be something to the abbreviated motion but it's probably not an advantage for most players. Bruce Elliot \is working on an article for us that says it is more or less safe but your experience is pretty typical of people I have worked with.
