I'm talking about vertical oscillation and ground contact time recorded by Forerunner 620, can we learn from them how to change our running style to a better one? It would be nice if Garmin makes a clear explanation on which is the correct way to use this data explaining how pratically we have to do. Otherwise they are just numbers without a value.
The running dynamics are like HR: it's up to you to determine how to use them. Garmin records the metrics, but the rest is up to you.
I have to agree with you. The info is out there and all that needs to be done is to google it. Besides a good coach should already know, and if you are that serious about training, you should have one.
We seem to have to got 2 parallel threads going on this. As such I will close this and suggest we move over the discussion to the 620 thread as this stuff is only on that device.
