Shoulder Strength Calculator

Get started with shoulder handheld dynamometry

New to shoulder strength testing? Need help getting started?

I created this tool to encourage more clinicians to objectively test shoulder strength with their patients.

Plug in activity level, sex, age, height, and weight.

The calculator will spit out strength for your selected test.

What's included?

• A three-page Google Sheet
  • Tab one is the calculator
  • Tab two contains testing instructions
  • Tab three shows the equations used to estimate strength

FAQs:

1. How do I edit the calculator?

Make your own copy of the Google Sheet to edit it. Permissions on the original document are set to view only.

2. Are these equations based on any research?

Yes, these equations are based on regression models from the research article linked here.

3. What study population was used to create the regression models?

This study used a convenience sample of 400 participants of varying activity levels between the ages of 20 and 59 years old.

These models are not intended to be used for elite athletic populations.

Anecdotally, these estimates are the minimum strength levels I would expect to see in elite level baseball players and other overhead athletes.
