Hey,
I'm pretty new to 3D kinematic analysis in sports, and I'm trying to follow this "protocol", i.e. the exact structure of results as in this article: https://peerj.com/articles/10841/
However, I think I understand how they are calculating the angles at key events and ROM, but I'm not sure how they are calculating the "angular changing rate".
As a data, I have a time series of angular velocity and acceleration. But how do you get just "one number" from time series? Is it also at key events, or can I calculate the "angular changing rate" leading to having just one number from a time series?
Thanks!
Hi. If a = 20 deg. b = 50 deg.
When the time at a is 0 s, b is 0.2 s. So, the event from a to b are 0.2 seconds And the anguler change rate that is (50-20)/50, the unit is %. So, the ROM is 50-20, unit is deg.
