• The following parameters were measured by means of a spirometer for 13 female and 49 male subjects (Judoka, experienced in competition with a mean age of 27.6 yrs, sd=10.3 yrs) before and immediately after crosshanded choking (Juji-jime) : FVC, FEV 1,FEV1/FVC, FEF 25-75,PEF, PIF, MEF 75,MEF 50,MEF 25,VC, IC, TV, IRV, ERV, and MVV. Significant changes were seen in FVC, which was reduced in an order of 0.24l, in FEV1,which decreased by 0.36l, in the ERV, which was reduced by 0.23l, and the MVV, which decreased by 6.3l/min. The VC showed a slight reduction of approximately 0.1l after choking, and FEV1/FVC-ratio increased in an order of 1%. None of the other recorded parameters showed any clinically relevant alterations. In conclusion, there was no indication that choking provoked an airway obstruction. Protective factors such as a high release of cortisol before choking as part of a general stress-response should be discussed.
