Introduction: Distorted processing of auditory information has a negative impact on the child’s cognitive development. There are only a few studies conducted by Polish researchers determining the normative values of psychoacoustic tests in auditory processing disorders. They are inconsistent due to different methodologies and different research protocols. Objective: The aim of the work was to determine the reference values of selected psychoacoustic tests for the population of Polish children between 7 and 12 years of age. Material and method: The study group consisted of 213 healthy children from 7 to 12 years of age. The condition for including the child in the study was an intellectual norm, proper sound sensitivity, proper development of children’s voice and speech. All children underwent two auditory temporal processing tests. The diagnostic procedure used a standardized Frequency Pattern Test (FPT) and Duration Pattern Test (DPT). The tests were carried out in accordance with the authors’ recommendations, using the original versions available on the CD for 60 dB SL intensity, simultaneously for the right and left ear. Results: The reference values for FPT and DPT tests were determined at various age ranges in children aged 7–12. It has been shown that auditory functions change with age and development of the child. Reference values including age, language, cultural and educational differences were prepared. Conclusions: The development of reference values for individual tests for the Polish children population is a key element in the reliable diagnosis of auditory processing.

The aim of this study was to characterize changes in maximal oxygen uptake over several years and to elaborate current reference values of this index based on determinations carried out in large and representative groups of top Polish rowers. For this study 81 female and 159 male rowers from the sub-junior to senior categories were recruited from the Polish National Team and its direct backup. All the subjects performed an incremental exercise test on a rowing ergometer. During the test maximal oxygen uptake was measured with the BxB method. The calculated reference values for elite Polish junior and U23 rowers allowed to evaluate the athletes’ fitness level against the respective reference group and may aid the coach in controlling the training process. Mean values of VO2max achieved by members of the top Polish rowing crews who over the last five years competed in the Olympic Games or World Championships were also presented. The results of the research on the “trainability” of the maximal oxygen uptake may lead to a conclusion that the growth rate of the index is larger in case of high-level athletes and that the index (in absolute values) increases significantly between the age of 19-22 years (U23 category).
