University of Portsmouth Octopush Clubs' mail group. Octopush or underwater hockey as it is also known, was actually started in the very pool we train in every week! It involves teams, chasing a puck (similar to an ice hockey one) around on the bottom of the pool.The team consists of forwards, mids and backs. It is their aim to try to score as many goals as possible, in the metal goals sunk at either end of the pool. For more information see www.pompeyocto.co.uk
