The study aimed to analyze the tarsus and knee setting in 3-year-old girls and boys, taking into account the six-month age ranges. Methods: The study involved 800 children (400 girls, 400 boys) recruited from randomly selected preschools in the in the Podkarpackie voivodeship. Study group was divided into two age ranges: 1st group (children aged 3.00–3.49 years) and 2nd group (children aged 3.50–3.99 years). Baseline goniometer (Fei Fabrication, Ltd., USA) was used as primary research tool. The data were analyzed based on Mann–Whitney U-test and Student’s t-test for independent samples. Results: Sex differences concern only the tibio-calcaneal angle in children in the 2nd age group (right: p < 0.001) and left p < 0.001). Statistically significant differences in both girls (right lower limb: p = 0.003; left lower limb: p = 0.002), and boys (right lower limb: p = 0.001; left lower limb: p = 0.001) were found. Conclusions: Boys were characterized by greater valgus of the tarsus of the right and left foot than girls. Knees of girls and boys in the 1st age group were characterized by greater valgus, compared to children from the 2nd age group.

Wymiary stóp dzieci zależą od płci i wieku. Jednak, ze względu na trend sekularny, a także zmiany demograficzne, wymiary stóp mogą ulec zmianie. W latach 2007-13 IPS przeprowadził pomiary antropometryczne w galeriach handlowych, w miastach Polski. Projekt Akademia Zdrowej Stopy został zrealizowany dzięki inicjatywie firmy BARTEK i jej wsparciu finansowemu. Przebadano 4996 chłopców w wieku 1-11 lat. Zmierzono 7 parametrów mających decydujący wpływ na wymiary kopyt i obuwia. Równolegle wykonano plantogramy, w których wyznaczono kąt Clarke'a oraz kąty alfa, beta i gamma służące jako wskaźniki kształtu stopy.

It is an obvious fact, that dimensions of children’s feet depend on gender and age. However, due to the secular trend, as well as demographical changes the dimensional parameters of the feet may change. In years 2007-13 IPS carried out anthropometric measurements in malls in cities of Poland. The project called The healthy Foot Academy was realized thanks to the initiative of BARTEK company and its financial support. 4996 boys aged 1-11 were examined. 7 parameters, having a decisive impact on the dimensions of lasts and footwear, were measured. Simultaneously there were made plantograms, in which the Clarke’s angle were determined, as well as α,β,γ angles used as indicators of the foot shape.

Celem pracy była ocena poziomu sprawności fizycznej uczniów Ogólnokształcącego Liceum Lotniczego (OLL) w Dęblinie na tle grupy porównawczej. Badania sprawności fizycznej przeprowadzono w grudniu 2009 roku. Objęto nimi 129 chłopców. Do oceny usprawnienia uczniów zastosowano zestaw prób motorycznych wchodzących w skład Europejskiego Testu Sprawności Fizycznej (EUROFIT). W każdej grupie wiekowej wyliczono średnie arytmetyczne i odchylenia standardowe wszystkich ocenianych prób. W celu określenia różnic w poziomie sprawności fizycznej pomiędzy ocenianymi chłopcami a przeciętnymi uczniami zamieszkującymi województwo lubelskie, posłużono się skalą punktową T. Oceny istotności różnic dokonano przy pomocy testu t-Studenta dla danych niezależnych. Ogólna sprawność fizyczna kształtowała się u uczniów z OLL w Dęblinie na wyższym poziomie niż u ich rówieśników. Wyraźne różnice odnotowano w próbach szybkości kończyny górnej, skoczności, siły tułowia, gibkości tułowia oraz sile funkcjonalnej. Aczkolwiek należy zaznaczyć, iż oceniani uczniowie charakteryzowali się istotnie niższym poziomem równowagi. W pozostałych analizowanych próbach różnice w poziomie usprawnienia nie były tak wyraźne.

This study was undertaken in order to evaluate the level of physical fitness of boys from the Secondary Aviation School (SAS) (OLL) in Dęblin in respect of a comparative group. Examinations of physical fitness were conducted in December 2009 and covered 129 pupils. Their fitness was evaluated with the use of a battery of motor tests being a part of the European Physical Fitness Test (EUROFIT). In each age category, arithmetic means and standard deviations were calculated for the results achieved in all motor tests. Differences in the level of physical fitness between the surveyed boys and their average peers inhabiting the Lubelskie Province were determined with a T point scale. In turn, the significance of difference was evaluated with the use of the Student’s test for independent variables. The boys from SAS in Dęblin were characterized by a higher level of general physical fitness, as compared to their average peers. Distinct differences were noted in the tests of upper limb speed, explosive strength, trunk strength, trunk suppleness and functional strength. It should be noticed, however, that the boys examined were characterized by a significantly lower level of balance. In the other analyzed tests, the differences in the level of physical fitness were not so remarkable.

The purpose of this study was to compare the changes in power and speed of running versus time for 11 year-old boys training (n-17) endurance competitions and being out of training (n-17). The estimate bases were the changing speed of power on an inclined plane and the change of speed for 400 m run in 25 m sections. In both tests each effort required maximal intensity. During the experimental period very similar characters of speed and power changes versus time were obtained for both tested groups and the differences are due to the training degree.
