Abstract: The invention relates to a turning plate for measuring the pushing-off forces of swimmers in a swimming pool when turning and includes force sensors for determining the pushing-off forces and a stiff plate, which can be secured in a stable position parallel to the pool wall. The turning plate has a stiff rectangular frame on which the stiff plate is secured with pre-tensioning by a clamping screw at four locations, in each case over a force sensor. Moreover, next to each of these force sensors, an adjusting pin is arranged on the frame and can be driven out from the frame in order to support the frame on the pool wall. The frame has at least one, preferably two stiff securing brackets for mounting it on the pool edge, preferably on a starting block.
