At what point is max. strength improvement not neccesary?

Also, as Charlie has mentioned many, many times before, as performance levels in sprinting improve, strength levels expressed in the weight room tend to reflect power output on the track, rather than vice versa. Once your basic strength levels are established well enough to permit proper execution of the sprinting technique, speed development tends to lead strength development, or perhaps more accurately, strength expression (given the right circumstances of recovery).

In other words, Ben didn’t run sub 10 in the 100m because he could squat 600 pounds. Rather, he could squat 600 pounds because he could run sub 10.

I definitely agree with this, one major thing I’ve noticed is bar speed improvements. On the flip side I think some are very quick to jump the gun where you state that strength training does have some benefits. That doesn’t mean you are making it the primary priority of your training. Having better relative strength has helped my explosion out of the blocks and through the acceleration.
