In a way..yes. Hard to separate them though. Since the glutes play a major role in both.
To keep it simple in my mind...I consider power as strength plus speed (quickness). Hip extension would be the power and rotation the quickness. Where they overlap would be the sweet spot.
I would like to see researches consider hip extension in their studies better. Seems like they are only studying rotation.
Like one of the more recent ones...it go this way. "Hip rotational velocity doesn't end up correlating between age and skill level...so its "Hip rotational energy" because of mass." (My paraphrase)
Mass plays a role for sure but fellows...maybe your leaving an important factor out!!
I would like to see them research hip extension and its role in power. I would also like to see them correlate hip extension to ball contact.
Someone will...just not sure why they haven't already.

How about shoulder rotational velocity?
Yes..throw that in there too. Shoulder rotational velocity prior into hip extension.
About the only reflexive..aka Natural...movement I think beginners have..when we get separation (core stretch) the body will want to rotate the shoulders to get them back in line with the hips. Everything else seems to be a learned motor program that we are trying to get to become reflexive.
Interesting...I will have to read up on Kvest studies. I always like taking these units to my wife...to get approval for buying! She has a $200.00 limit mentality when it comes to my softball spending. Trying to convince her its 2018...the good stuff is expensive.
The Kvest has been around in golf for years now from what I understand and is now working its way into baseball/softball. It is very pricey, I believe it is around the 5K mark. From what i can tell Justin Stone is kind of leading the way, or at least on a public level, of taking the Kvest data given to determine movement restrictions and improving overall sequencing. For example my DD readings show that is she in the proper sequencing 99% of the time but lacks efficiency in the transferring from one segment to the other. For example her hips are well into deceleration when the torso starts to accelerate and so on. The way Sierra's reading show each body segment a little staggered on top of each other is ideal. My DD readings are more like rolling hills that are spaced a little further apart.
I remember reading that men pro golfers hip rotation speed is slower than LPGA players kinda debunking quick hip rotation as THE power source. Have to believe that the stretch and how fast the shoulders are catapulted around is more important than hip speed. Golfers use a lot of lag too.
Which brings up another question for you guys: (where are you FFS?)

Can and /or should the hands "down cock" at all during launch? I believe they do to some extent naturally if hitter is employing light grip pressure. Should it be taught?

Nice! I would love to have that k-coach one with 4 sensors. I have looked at other equipment and they are all pretty pricey and I haven't pulled the plug yet.
Did they give your dd instruction on how to correct? And did it help her understand what she is trying to accomplish..."somewhat" or "very much so"?
Thanks in advance!
The K-vest that I am talking about is the K-coach.
As far as instruction goes it isn't your typical "Do this drill" type of stuff. It more or less revolves around Range of motion, strength, and mobility more than anything. So basically it is do a swing assessment with the vest and analyse the data and hopefully you can figure out where the disconnect is happening. Once that is figured your best bet is to go to a PT or something of that nature to do a mobility/rom assessment. Depending on the finding of the test will determine what instruction will best help the player. Whether the findings being a high range of motion in the right hip but poor mobility or the exact opposite (just an example). Once the player is able to move the way that they need to move, whether it be achieving the proper hip hinge or something else, you can start dialing in on the finer details of the sequence.
It has very much helped to understand what should be or needs to be taking place in the swing. It is all right in front of you. For example my DD hips are finished/open way to soon compared to most MLB hitters. Her hips are at 90 degrees and are done with rotation or very close to it at ball contact and I believe most professional hitters or around 80 degrees and still decelerating at contact. Her hips are around 60 degrees when the torso starts to accelerate compared to a pro at 30 degrees. My DD was one who was taught to fire those hips before her hands. I am not really sure if this is a contributing factor in the inefficiencies of her kinetic chain but I don't think it is helping.
Please take this stuff with a grain of salt. I have only played around with the Kvest a couple of times and was given information about it from someone who is also in the process of still learning it.

Regarding the top-hand wrist becoming bent/cocked/loaded ... in the baseball/softball swing the maximum bend/cock/load in the top-hand wrist occurs at the 'bat lag orientation'.
Is it important? Yes!
Do you actively try to make the top-hand bend? No!
How does one control the top-hand wrist bend? With proper looseness in the wrists and proper swing mechanics.

There’s that word again... lol.
