A piece of inflatable sports equipment, preferably for water sports, is provided with a board (1) which can be inflated with a gaseous medium, preferable air, by means of a pump unit (6) having a compressor (7). The pump unit (6) is integrated together with the compressor (7) in the board (1) and preferably comprises assemblies (8, 9, 11) which drive the compressor and are installed together in a housing (12) which can be removed from and inserted into the board (1) and fastened therein. Inflation of the board can therefore be carried out anywhere and at any time during use of the board, since the means necessary for this are installed in the board itself.
