Technical, perceptual and motor skills in novice-expert water polo players: an individual discriminant analysis for talent development.

The 4 tasks (A, B, C, and Y) have the characteristic of containing one more element than the task performed before it. In fact, task B introduces the slalom which is not present in task A. Task C introduces the ball control that are not present in tasks A and B, whereas task Y introduces the slalom and ball control in a visual dual task situation developed in horizontal swimming over a distance of 20 m at maximum speed.

The components of the jumps in expert and intermediate water polo players.

The aim of this study is to show the different multifactorial structure of jump capacity in expert and intermediate water polo players, using the principal component analysis (PCA) and multiple regression. We adopted the Teknotrain3, an instrument that enabled us to measure maximal height out of the water and dynamic components such as force, velocity, and power. The experts showed high levels of power (t = 2.
