Is a nice look at all the thoughts you are promoting here. Yes fast specific weight training can help the muscles get stronger through that specific ROM, I am not saying it cant, I am saying its stupid to use them when there are numerous known negative side effects to this thinking and other methods that offer all of the benefits and more with none of the side effects.
Does it work, yes. Is it intelligent or right, no.
Is your remark about ATP in connection with the cross bridge discussion?
“Th advantage of strength training if a very similar movement can be found is that one can overload the target muscles quite well because there is no alternating limbs to rest the neuromuscular system.”
which muscles would you be trying to overload in a sprint training programme?
Yes recruit pattern is good for the tissues involved i.e. only the appropriate fibres will make the speciifc metabolic adaptations required, the down side comes from learning a skill to do this that is different from the skill the cns knows for sprinting in a race- possibly and likely causing negative transfer and thus redcuing the spritning potential.
Without a doubt resistance training on its own will not help sprinting but any improvement in strength will benefit from sprint training as well. For example the squat can improve vertical jump by 4% but only help sprinting by 2% if velocity specific enough within the first 10m only. Is this gain worthwhile? Olympic lifts carry an increased chance of injury but are little better than fast squats and plyometrics within the first 10m. In fact, for those with poor hip extension strength/power (although not much is needed) OL may be the best choice. Granted all this is useless without concurrent sprint training. Are any of these methods better than a sprint program involving a combination of uphill and downhill sprinting? I would argue that it is unlikely. However I would also argue that there are improvements we can make to any of the above exercises instead of just accepting the status quo. My argument is based around the fact that less than 100kg of propulsive force is generated in total in a sprinting stride.
As for training the CNS with OL or resistance training, the two are not related. One is only training muscle fibre and connective tissue. OL muscle activation must come from the motor cortex. Plyometric training will more likely enhance the CNS (and the muscle recruitment thereof)as the spinal chord is known to be adaptable. Alternating limb plyometric activities and sprint training benefits the cross extension reflex activated muscle-connective tissue for sprinting.
Don’t worry about the argument getting personal – many great ideas have come so far from the debate. I think this is an excellent thread as most of us supplement our sprint training. I’m curious as to your training program and how much it has improved your sprinting as you are very adamant in your philosophy. (And I don’t think I’m disagreeing with you)
