title: [Performance diagnosis of the locomotor system and sensory organs?].
abstract: The quantitative significance of the sensory organs in sport is discussed by means of the visual parameters static and dynamic visual acuity and the equilibrium that is specific for a particular kind of sport. Spectators with normal visual acuity can identify footballs, tennis balls etc. used in game sports, with relative ease, compared with sports equipment used in athletics. However, since moving objects can attain an angular velocity of 400 degrees/s and higher in certain sports, the mean dynamic visual acuity is unable to cope with such speeds, this being only 200 to 230 degrees/s. Dynamic visual acuity can be trained, thus attaining higher levels in game sports. Processes of balance regulation during cycling (or in rhythmical sports gymnastics) are discussed in connection with and subsequent to the problem of the intersensory perception conflict. Finally, the article sums up criteria for the observation of movement and for minimising intersensory perception conflicts.
