periodization from Base to Build to Peak to Transition (to borrow Joe Friel's language), so that the body doesn't get hammered all the time and eventually succumb to over-training and injuries.
Periodization Training
This method works for everyone from Novice to Advance Athletes.
This is the backbone of Progressive Loading; for Strength, Power, Speed, Hypertrophy and Endurance Development.
I'm not sure taking a week off, only to jump straight back to Zone 4-5
Deload-Reload Misinformation
Many individual have been incorrectly lead to believe that once they hit a sticking point, Deloading for one or two workout out or taking a week off will get them back on track. It may initially them a jump start the following one or two workouts.
However, it is counter productive for long term results.
One of the keys to maintaining long term results is Planned Periodization Training in which a Progressive Overload occurs each week.
The final week of the Periodization Training Cycle is where the intensity of the program is maximized; push near to the limit or to the limit.
After the last intensive week of a Periodization Training, a new Periodization Training Program is begun tjhat less intense, fairly light loads.
Part of the new Periodization Training emphasis is on...
Active Recovery
Recovery is where gains in Strength and Size occur.
Active Recovery trigger growth by increasing blood flow to muscles and tissue.
In doing so, it delivers nutrients to the muscles and tissue, as well as taking out the garbage, metabolites.
Passive Recovery
This defined as taking time off from training, let's say a week.
This method has been show to be less effective than Active Recovery.
