The medical certificate is absolutely obligatory for the practice of
ping-pong in competition.
It must normally be signed by a doctor specialised in "sports medicine." For the season 2005-2006,
it must be posterior to 31/05/2005.
It must carry the mention indicating the "no opposition to the practice of ping-pong in competition".
Although it is not obligatory for the "leisure", we encourage you however to establish it.
