Physics consists in identifying repeatable sequences in our environment and finding the simplest underlying laws. In this colloquium, the environment is Sports and we have three main objectives:

- Walk in the footprints of modern precursors (JB Keller, TB Benjamin) and show that sports do entangle a large number of physical concepts which can be used to optimise performance.

- While applying the physical laws to this new domain, we expect that new questions or coupling will arise, and that new representations of physical phenomena will be proposed.

- Finally, a side product of this colloquium is to show that sports can be an important vector for the presentation of advanced physical concepts. As a striking example, the quantum tunnel effect which is illustrated in figure 1 where the jumper passes over the bar despite the fact that his centre of mass always remains below the bar.

In order to make links and establish the generic laws in different sports, the colloquium is structured in six Physics domains: Ballistics, Elasticity, Friction, Statistical physics, Waves & Fluids and Biomechanics. Each domain is detailed below and associated with invited speakers.
