anyone with delayed muscle relaxation after contraction or percussion?

Nothing is showing up at EMG, but I'm still questioning this symptom, as I'm not sure if it means something special...

most likely a chanel myocyte dysfunction but it may be a common thing among healthy people as well...

Here a video of percussion at my shoulder muscle, but it's also easy to see it at trapezius or other muscles in arms or other places...
