Volleyball coach friend has a magic trick when testing vertical jump: He instructs the players to go faster on the next attempt and voila their numbers improve... 🪄🧙‍♂️ Depth and velocity matter for countermovement jump assessment metrics (including jump height) 👇

I worked with Dan Cottrell at Rugby Coach Weekly to outline a clear distinction for coaches between sessions aimed improving performance and those aimed at improving learning, and when each type of session could be useful. You can find it here: rugbycoachweekly.net/rugby-coaching… 1/2

A reliable way of making people believe in falsehoods is frequent repetition because familiarity is not easily distinguished from the truth.

“it is difficult to accept that the best learning road is slow, and that doing poorly now is essential for better performance later. It is so deeply counterintuitive that it fools the learners themselves” - David Epstein

Great post by Sian Allen. Important for volleyball clubs these days to realize that we are a late specialization sport. Don’t force kids to choose at younger levels.
