My DS is in trampolining and had a long time of struggle with Lost Skill Syndrome (nowadays also known as twisties (thank you Simone for making this subject more public). He also had growth related injuries, no training because of Covid etc. Yet he did not quit. Just weeks ago when he finally started training after 6 months without training because of Covid his LSS / twisties / mental blocks caused him to not be able to take of for a simple back somersault. He needed asistance from his coach to do that. Now it is just a few weeks later and we were on holiday in Crete. I was quite terified but DS did this. He is by no means a reckless kid, he checked under water and we know he has the skill. That is why we allowed him.
