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.

im pretty sure of this...Example: doing a bicep curl....when you do an eccentric contraction as in letting the weight down with gravity....and you stop at the bottom of that contraction...you bicep is pre loaded. The muscle is very tight and ready for the concentric contraction. Hope that helps!
