Pre-Loading Muscles

[busupshot83]

On pg. 9 of the NSCA-CSCS Essentials textbook, the concept of pre-loading is presented: "[when] high tension is devloped in a muscle even before movement occurs... because the weight must be supported isometrically." By "isometrically," are they referring to "isometric muscle contractions?"

Still, I find the textbook's explanation to be unclear. Can someone explain the concept of pre-loading in their own words? Thanks.

Now, my understanding might not be what the textbook is actually describing, but I looked up the word isometric, and this is what I think is being described: The person invokes a relaxed current through the muscles he is about to use, and the support muscles. This relax current preps the muscle tissue, releasing it from it's current memory state and takes it into a new 'free prepared' state, where once in action, it will calibrate instantly with the coming activity, resting in a new memory state that best compliments the requirements of the action task.
