It is indeed called that yes, however, what you fail to realise is the realtionship between the speed of ATP disruption and the velocity at which you move. The faster you ask the contractile elements to contract and realease the less of them can and HAVE to do so. There is simply not enough time to allow for the chemical reactions to happen to allow for full cross bridging of all proteins. If they did all cross bridge successfully and you continued to move at full speed they would be damaged fairly seriously due to the forcefull ripping apart of the bridges as opposed to the chemical release that happens. Cant connect and HAVE to not connect at high speeds.

“Shortening at high speed, preventing most of cross- bridges from undergoing the relatively fast (100 s-1) detachment/reattachment process, uncovers a rate limiting step in the cycle at the end of the 12 nm working stroke”
is just one study showing the relationship. the faster you move the less cross bridges can and have to form.
Are you still in dispute of velocity and reduced cross bridge formation?
Strength training is specific to nothing and everything, the ability of a musccle fibre to tolerate a tension is the strength of a fibre, the displaying of that strength is the skill of what ever movement you wish to utilise that strength for. Strength is general, skill is specific – any time you move, is skill ffrom the CNS. How you choose to display your tensile ability is up to you or your sport, that does not mean that is the best way to increase your tensile strength abilities.
I fail to see how the motor learning skill transfer and SAID principle does not make sports specific training clear. You get good at what you do – train OL get good at OL, any carry over that may be shown is due to the increased tensile strength of the tissues invovled – not the CNS or the skill of OL. Getting good at jumping with a barbell will make you good at,well, jumping with a barbell and not make you better at jumping without a barbell any more than jump practice with strength training will. Practice sprinting off the blocks, to get good at – you guessed it, sprinting off the blocks. They will increase tensile strength, one will induce neagtive transfer. All coaches should be aware of negative transfer and how it effects athletes.
And they should also be aware of long term effects their current sports specific training has on athletes especially if there are other less damaging methods readily available to them. Duty of care springs to mind.
Plyometrics – sports contain plenty of those during play, why train thme unspecifically outside of play.
the plyometrics experienced by the CNS during a sprint can only be mimmicked by sprinting. jumping and bounding may be similar in the sense of what a muscle experiences,true, the cns sees them totally differently and that is the point here.
You are mistaking excititation with skill, yes the skills learnt will be totally different between the lifts.The characteristics of the CNS will be the same.
