Maximum strength is only a part of the equation. Rate of foce development is extremly important in athlethics. To understand why, study the force-time functions, and couple it with the basic truth that many sporting actions actually have a time spawn shorter then the time required for the biological organism to develop maximum force.
Many times, especially for high level athlethes with fairly high levels of strength, training max-strength as a focus of training is counterporductive. Instead , training designed to optimize RFD should be focused.Furthermore the training should be different depending on what portion of the force time curve is targeted by the sporting event trained, mainly explosive strength or stating strength. "Speed" is still king in sports.
This is not to say max-strength is not important. Yet blindly training for more and more max-stregth will not always reflect in better performance on field. Dont be over-concerned with results in weight room. Gauge gains though sporting results and advancement in the process of obtaining sport mastery. This is what should be important, for both the coach and sportman.
