Treppe is also known as the staircase effect. The picture shows that over time, repeated and equal stimuli (an event or thing that causes something to happen) causes the muscle contraction to increase in intensity. So in the image you can see the steady waves. They're equally apart, but they reach a higher level of intensity over time. Think of a staircase. The steps are the same distance apart, however over time you get higher. Hope this helps!
