摘要：Spirometry can be considered a method for measuring lung capacity and speed of air-flow through theairways. Due to its simple application, it is commonly used in sport diagnostics. Aims of this research were todetermine the values of ventilation function variables in karatekas competing in kumite discipline and theirrelationship to result. The sample included 51 junior karate athletes (with defined subgroups of moresuccessful [n=31] and less successful [n=20]), competing in kumite discipline, from nine European countries.Their values of some ventilation function variables were measured. Measurement procedures were chosenand used according to acknowledged literature. By univariate analysis of differences, significant differencesbetween more successful and less successful competitors were determined in the following variables: forcedvital capacity (more successful 5.24±0.56 l; less successful 4.27±0.61 l; p=0.00), forced expiratory volumein 1 second (more successful 4.13±0.68 l; less successful 3.69±0.57 l; p=0.02), ratio of forced expiratoryvolume in 1 second/forced vital capacity (more successful 78.98±10.29%; less successful 86.64±8.37%;p=0.01) and maximal voluntary ventilation (more successful 150.46±31.14 l/min; less successful125.50±29.49 l/min; p=0.01). More successful contestants showed higher values in some relevant variablescompared to less successful ones supporting a relationship to result.
