Residual training effect is how long the body "holds on" to an adaptation with direct training before it starts to decline.
To me, residual training effect matters most in-season when you have to prioritize what gets trained with fewer training exposures.
In the offseason you have plenty of time and recovery to train all major qualities continuously.
Two main adaptations we'll look at today are maximal strength and speed.
The residual training effect for max strength is about 30 days.
That means a well trained athlete will retain most of their maximal strength without directly training it for about 3-4 weeks.
Speed is not the same.
Speed will begin to decline after about 7 days without direct exposure.
So what does this mean for programming?
It means when we start to whittle away our prioritizes in-season, speed and power must always make the list each week.
Strength takes much less to maintain.
So, what's the strategy for in-season training?
About 15 to 20 total sets per session, twice a week, keeping the main lift moderate-heavy.
Now, let's talk speed.
Sprinting about twice a week is enough to retain, and even continue to develop speed.
Two max effort reps at 10-20 yards twice per week will get it done.
Even once will have an impact if you're that limited on time.
The beauty of all this is in realizing that it takes much less training volume than most think to still get the results they need.
It's all about understand how much that is and prioritizing what gives you the largest return on the time and effort expense.
