N2  - The purpose of this study was to investigate the influence of frontal breathing on the kinematics of the stroke cycle in butterfly swimming. A group of 11 female swimmers was divided according to their performance level and performed 4 x 50 m repeats with 6 min of rest, 2 at 75% and 2 at 95% of best performance in the 100m butterfly, 2 with free breathing (v75R and v95R) and 2 in which the swimmer restrained from breathing in the second 25 m (v75NR and v95NR). The swimmers were filmed in the sagital plane underwater and above the water with synchronised cameras and images were analysed for kinematic data. In the least skilled swimmers, maximal positive inclination of the trunk declined from 32.14°+/-4.06 to 24.08°+/-3.01 and from 33.5°+/-5.72 to 24.63°+/-1.44, when breathing was restrained at, respectively v75 and v95. In the more skilled swimmers, frontal breathing caused a longer downsweep at v75 and a deeper kick at v95. The pernicious effect of the lifting of the head was weakened in the case of the more skilled swimmers with the increase of velocity, but not for the other group.    Verf.-Referat
