Are dwarfs able to participate in athletic activities?
Yes, within the limits of their individual medical diagnoses. For instance, swimming and bicycling are often recommended for people with skeletal dysplasias, since those activities do not put any pressure on the spine. Long-distance running or even extensive walking can be harmful because of the constant pounding, although, as a rule, healthy dwarf children without any unusual orthopedic problems should be allowed to engage in normal running-around.
