The article presents the possibility of using Zwicky’s morphological analysis in the ergonomic design of devices supporting sports activity of people with disabilities. As an example, running trolleys for marathons were analyzed, which in most cases have a very similar form. The advantages and disadvantages of the selected attributes have been analyzed for the selected alternatives, which in the context of ergonomic design makes it possible to reject an unacceptable solutions. In the analyzed example, the following categories were considered to be relevant attributes: Number of wheels (Ai), Position on the seat (Bj), Direction of the passenger’s wheelchair position (Ck), Handle body part (Dl), Wheel steering (Ei), Power transmission through a specific part of the body (Fm). Finally, it was shown that even with a small effort for a number of solutions functioning invariably, interesting alternatives can be found.
