They may be able to Grow without rest…But How will they perform long term…If you don’t allow them to recuperate from strenuous excercise or if you have DOMS how much positive effort could you really train with?
Red, that is a theoretically good question but one that has never been tested emperically since it is not practical to have a muscle under CONSTANT tension except in a laboratory environment. Under Haycock’s protocol, you do allow for rest. However, you do not need a whole week of rest because of the lower intensity and volume. As for DOMS, unless you have actually caused more damage than mere microtrauma, which then would be more than DOMS, you can still exercise and grow. In fact, it has been shown that working thru microtrauma is better for ‘hypertrophy’ than waiting for DOMS to completely vanish. Sources behind these independent studies can be found on Haycock’s website as well as other research sites. I do not believe that it is possible for the average advanced lifter to approach his genetic potential without having a basic understanding of why muscles grow so that he may adapt training principles to his own unique situation. After 45 years of lifting, I still haven’t hit that plateau which means I still have a lot to learn.
