[quote author="Chad Williams" date="1258324363"]Do light loads work the neuromuscular system harder than heavy loads? None of the means you mention are specific means to sprinting, they are general means.
It depends on the time of year and what you are trying to achieve. Certain tasks will be more specific to the athletes goals given the context of the training cycle.
Neuromuscular coordination is certainly more challenging at greater speeds. Try throwing a baseball at 70% and controlling it v. throwing it all out and controlling it.
All weight room tasks will utilize the neuromuscular system, so does typing on this computer. But I fairly certain that me sitting here typing is not making me a better athlete.
To answer Mr. Glove’s example more specifically. I think with your example his squat will go up with time and training age. Therefore, it shouldn’t be a major concern. In season, the focus should be on the track and perhaps some exercises that will coincide with the goals at the time. Perhaps some exercises that will work on elastic qualities and hip extension along with trunk stabilization.
