metabolic endurance calculator

I love this new tool!! However, I have a few questions:
1. What dos SSHR mean?
2. Why does it need both a 2 min. and 3 min. HR? The protocols call for one or the other. Is it ok to put in the same number. I have found that it only works when both boxes have numbers in them.

SSHR and more...
I am glad that you are enjoying the MET calculators!
SSHR = Steady State Heart Rate - this is important because each of the tests assumes that the heart rate is above 110.
All tests assume that there is not more than 5 beats per minute variance between 2 minutes and 3 minutes this is why both the 2 & 3 minute heart rates are needed.
If you still have additional questions, please let me know.

The answer Peggy is not completely accurate.
The 5 beat per minute issue has to do with the person being in Steady State Heart Rate. If readings one minute apart are more than 5 bpm different, the readings indicate that the person's heart rate is still responding to the work load and is not steady. If the readings are more than 5 bpm apart at the second and third, or third and fourth minutes, either keep the person working or increase the work load. This assumes, of course, that the person is safe.
No, you cannot enter the same number in both boxes just to get the math to calculate. If you do you are not doing the test reliably.
