Sažetak

This paper analyzes the precise distance measurements of a long course Olympic-size swimming pool lanes in the swimming pool complex Svetice in Zagreb. Geodetic survey of 10 longitudinal pool lanes distance was performed with a hand-held laser distance meter. It is concluded that the distances of all swimming pool lanes are within dimensional tolerances provided by International Swimming Federation. By processing the data, statistical parameters of pool distances are determined. Standard measurement uncertainty of Type A, standard measurement uncertainty of Type B, combined standard measurement uncertainty and expanded measurement uncertainty are shown as measurement quality parameters. Comparative analysis between the accuracy of time measurement in swimming competitions and the distance measurement of the swimming pool is shown. It is concluded that the maximum allowable deviation from the prescribed dimensions of the pool lanes does not affect the results achieved by swimmers in competitions.
