I started analyzing baseball pitching movements.

The target is 12 high school pitchers.

Using Noraxon's Myo Motion system

Analyze the data of the fast ball.

In Japan it is said that there is no consensus on biomechanical analysis of shoulder joints in pitching motion.

My question is,

It is about how to use the combined acceleration of the upper arm throwing the ball, calculated from tri-axial accelerometers data.

I would like to use this combined acceleration value as an index of the kinetic chain arising from the range of motion of the joints of the L/E and trank.

Is there something wrong with this?

I would appreciate it if you could give me advice.
