- The PAP and PAPE effects can improve your performance in the short term.
- The ideal time for peak effect is between 3 and 12 minutes.
- The effects can be used in both sports and training.
What are the "PAP" and "PAPE" effects?
Imagine you do some heavy squats or deadlifts and suddenly you're jumping a little higher, running faster or lifting a barbell a little more easily than you did a moment ago. Does that sound like nonsense? No — it's a physiological effect known as PAP or PAPE.
Post‑Activation Potentiation (PAP) and Post‑Activation Performance Enhancement (PAPE) refer to phenomena where there is a short‑term improvement in performance after a previous intense load. This may result in a higher jump, a stronger punch or a faster sprint. This can be used purposefully not only in the sport itself, when we want to give the best possible performance, but also in training to increase the actual intensity of the exercise, which is often the goal.
So, what is actually hidden under the acronyms PAP and PAPE?
PAP - or Post Activation Potentiation - is a neurophysiological, short‑term effect (most often lasting from seconds to about 3 minutes) that is measured mainly at the muscle level. You can think of it as something that makes your muscles more sensitive to nerve excitation and the subsequent contraction, which can help, for example, in jumping.
PAPE - or Post Activation Performance Enhancement - is also a physiological effect, but unlike the PAP effect, it is measurable at the level of broader performance (e.g. performance in a selected sport). It has a longer duration and works not only through increased muscle toning but also via increased body temperature, muscle blood flow, etc.
What is the difference between the two effects?
PAPE is what we use to improve athletic performance and is the result of a wider range of changes. PAP works more at the level of the muscle cell itself and is used more for single, simple movements. In sports itself, therefore, we are more likely to be interested in the effect of PAPE, particularly in its translation into performance, although the effects may ultimately overlap.
When and how can we use them?
The first way to use these effects is, for example, before a speed or explosive performance that we would like to potentiate, i.e. improve. So, if we want to increase our jump height or sprint speed, and thus the intensity and effect of these exercises, incorporating methods to induce the PAP/PAPE effect can be a great option.
Another option, which is also often used in practice, is to include it in the warm‑up before a sports performance. According to one of the widely used R.A.M.P. performance preparation protocols (which we will write about next time), the potentiation exercise (P –potentiation) is included at the end of the warm‑up to get the athlete ready for maximum performance. Often, jumping or plyometric exercises (e.g., several jumps in quick succession) are included at the end to improve subsequent sports performance.
The last option we will consider is using the contrast method in strength training. This method is often employed when the goal is not only to develop maximum strength or muscle volume but also explosive power or speed. In practice, this method involves combining two exercises (e.g., heavy squats followed by lunges), with the first exercise serving as a potentiator for the second, more dynamic one.
It is also important to note that the effects of PAP and PAPE do not occur immediately, but most often within 3–9 minutes after the application of the potentiating exercise. Therefore, the ideal approach is to first test when the effect is most apparent (e.g., by measuring an increase in jump height), and then use this time interval, such as in the contrast method, for optimal results.
Practical examples of use
In this section, we’ll show two selected options that you can try in your own training. In the first example, we focus on potentiating maximum jump height; in the second, we look at how to apply the contrast method.
Example 1: Heavy squat → 3‑6 minute pause → vertical jump test
In this example, we use a heavy squat — approximately 85% of 1RM (i.e. 85% of your estimated maximum weight) — as a potentiator. Perform 2–3 reps at this weight, followed by a 3–6 minute pause. Then, attempt a maximal vertical jump. You can test this by reaching for a wall or using the MyJump app to measure jump height. Compare the result with your previous maximum. If performance has not improved or has declined, try increasing the rest period for the second set.
Example 2: Bench press → 3 minutes rest → medicine ball throws
In this example, we explore the potentiation effect within the contrast method.
- First, perform 1–3 reps of the bench press at 85% of your 1RM.
- Then, rest for 3 minutes, followed by 3–5 dynamic medicine ball throws against a wall.
While there may be no precise way to measure whether you're throwing harder, the ball should feel lighter compared to when the potentiation wasn’t applied.
Bottom line
PAP and PAPE are effects that, with the right timing and method, can help us get a little more out of our training. Whether we want to jump higher, run faster or feel more powerful, the right potentiation can support all of these goals.
However, it’s important to remember that this enhancement won’t work the same for everyone. The key to optimal use is self‑testing — this might mean experimenting with rest intervals or determining which method of induction works best for you.
Just like an engine benefits from a good warm‑up before running at full speed, a well‑targeted activation can help your body "hit the gas" a little harder — if you choose the right tools to do so.
