Pre-Loading Muscles
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.
