    Opis:
    Theoretical background: A sports career is a specific activity because it starts at an early age, lasts a relatively short time, and usually athletes are most successful when their peers are just starting to develop their typical professional careers. In previous research on the second careers of ex-athletes, mainly the top performers were described, forgetting that many athletes play in the lower leagues and sport is also their main profession. In this study, athletes who played at different levels of competition were analysed. Purpose of the article: The article aims to determine how the length of a sports career affects the second professional career of former athletes. Research methods: The studied population were Polish basketball players of working-age after finishing their sports careers. The survey was conducted online in 2021 and 301 people took part in it. The average duration of a sports career of participants was 10.13 years. Former basketball players were divided into 2 groups according to their career length. The first group consisted of those whose basketball careers lasted at least 10 years (160 people), and the second group consisted of those whose careers were shorter than 10 years (141 people). Main findings: Former players whose sports careers lasted for at least 10 years are more satisfied with them than those whose sports careers were shorter, but they assess their current career prospects worse. It may result from the fact that among those whose sports careers were shorter, a greater percentage have higher education. The results also show that those whose basketball careers were longer, are now more likely to work in the field of sport. In conclusion, it can be said that earlier retirement from sports, favours to a greater extent university graduating and also allows a faster transition to a second professional career.

    Opis:
    With respect to cyclic movements such as human gait, running or hopping, leg stiffness is a little variable parameter. The aim of this study was to investigate changes in leg stiffness during the phase of countermovement and take-off when performing a single maximum counter-movement jump. Kistler force plates and a BTS SMART system for comprehensive motion analysis were employed in the study. The study covered a group of 12 athletes from university basketball teams. Leg stiffness was calculated in those parts of countermovement and take-off phases where its level is relatively constant and the relationship F(Δl) is similar to linear one. Mean total stiffness (±SD) in both legs in the countermovement phase amounted to 6.5 ± 1.5 kN/m, whereas during the take-off phase this value was 6.9 ± 1 kN/m. No statistically significant differences were found between leg stiffness during the countermovement phase and takeoff phase in the study group at the level of significance set at α = 0.05. This suggests that the leg stiffness in phase of countermovement and phase of take-off are much similar to each other, despite different function of both phases. Similar to cyclic movements, leg stiffness turned out relatively constant when performing a single vertical jump. There are also reported statistically significant correlations between body mass, body height, length of lower limbs and leg stiffness. The stiffness analysed by the authors should be understood as quasi-stiffness because the measurements of ΔF(Δl) were made during transient states where inertia and dumping forces are likely to affect the final result.

    Opis:
    The anterior cruciate ligament (ACL) tear is a common injury in basketball. Its consequence is a long absence from training, resulting from surgical treatment and long physiotherapy. The aim of the study was to assess muscle strength, postural stability and functional movements in female basketball players, who returned to professional sport careers after anterior cruciate ligament reconstruction. Methods: The study population consisted of 10 female basketball players after surgical reconstruction of anterior cruciate ligament. The control group consisted of 10 players without ACL injury. We used the Biodex System 4 Pro dynamometer to assess the muscle strength of the knee. We used it to conduct the test of flexors and extensors of the knee in isokinetic conditions. We also used Keiser Power Squat A300 in the single leg squat to measure power and the Biodex Balance SD dynamographic platform to assess balance in single leg stance. Results: We found deficits in both movement patterns and in muscle strength in the study population, compared to control group. Conclusions: The basketball players after ACL reconstruction had significant differences between the operated and non-operated limb. The differences may predispose them towards repeated ACL injuries.

    Opis:
    Purpose: The aim of this study was to present the methodology for estimation of a leg stiffness during a countermovement jump. The question was asked whether leg stiffness in the countermovement and take-off phases are similar to each other as demonstrated in previous reports. It was also examined whether the stiffness in left lower limb is similar to the one in right lower limb. Methods: The research was conducted on 35 basketball players. Each participant performed three countermovement jumps with arm swing to the maximum height. Measurements employed a Kistlerforce plate and a BTS SMART system for motion analysis. Leg stiffness (understood as an inclination of the curve of ground reaction forces vs. length) was computed for these parts of countermovement and take-off phases where its value was relatively constant and F(∆l) relationship was similar to linear. Results: Mean value (±SD) of total stiffness of both lower limbs in the countermovement phase was 7.1 ± 2.3 kN/m, whereas this value in the take-off phase was 7.5 ± 1 kN/m. No statistically significant differences were found between the leg stiffness in the countermovement and the take-off phases. No statistically significant differences were found during the comparison of the stiffness in the right and left lower limb. Conclusions: The calculation methodology allows us to estimate the value of leg stiffness based on the actual shape of F(∆l) curve rather than on extreme values of ∆F and ∆l. Despite different tasks of the countermovement and the take-off phases, leg stiffness in these phases is very similar. Leg stiffness during a single vertical jump maintains a relatively constant value in the parts with a small value of acceleration.

    Opis:
    The article is focused on description of the sociolect of polish female basketball players. Through the analysis of spoken (recordings from the matches and press conferences) and written sources (websites dedicated to female basketball) it was possible to create the basketball dictionary with about 160 lexical entries. The basketball lexicon consists of words taken from other sociolects and those created inside the basketball environment. It is affected by two main opposing tendencies - to precision and sparing with words. The sociolect of female basketball players is focused on the game and its rules in offense and defense, how the basketball court looks like and how the players call for each other. The language tendencies, characteristic for the sport, such as: metaphor of a basketball match as a war, appreciation of bravery, reflex and common work for the good of the team, are also visible.
    Artykuł stanowi próbę opisu socjolektu zawodniczek żeńskich drużyn koszykarskich.Dzięki analizie źródeł mówionych (nagrania z meczów i konferencji prasowych) oraz pisanych (strony poświęcone koszykówce żeńskiej) udało się stworzyć słownik koszykarski liczący około 160 jednostek leksykalnych, rejestrujący jedynie słownictwo swoiste.Na leksykę socjolektu koszykarskiego składają się zarówno jednostki leksykalne przejęte z innych źródeł, jak i te wytworzone bezpośrednio na gruncie środowiskowym.Wpływają na nią dwie przeciwstawne tendencje – do precyzji i skrótu.Koncentruje się ona wokół gry i jej elementów – sposobów i zasad gry w ataku i obronie, wyglądu boiska, nazw zawodniczek.W leksyce koszykarskiej uwidacznia się charakterystyczny dla odmian sportowych językowy obraz świata: metafora meczu jako wojny, docenianie waleczności, refleksu oraz gry zespołowej i wspólnej pracy dla dobra drużyny.

    Opis:
    Zawodnicy występujący w latach międzywojennych w polskiej lidze piłkarskiej byli bardzo wszechstronni i utalentowani, dlatego odnosili sukcesy sportowe także w innych dyscyplinach sportu. Celem pracy była ocena skali tego zjawiska. Masowy rozwój piłki nożnej w Polsce sprawił, że brakowało utalentowanych zawodników w zmaganiach obejmujących gry sportowe, lekkoatletykę czy sporty zimowe. Wysoka sprawność piłkarzy predystynowała ich do udziału w rywalizacji sekcji klubów sportowych, innych niż futbolowe. Przedstawiono szczegółowe wykazy piłkarzy, uczestników rozgrywek ligowych w latach 1927–1939, którzy zostali medalistami mistrzostw Polski w hokeju na lodzie, lekkoatletyce, koszykówce, siatkówce i piłce ręcznej. Ponadto zaprezentowano sylwetki i dokonania najbardziej wszechstronnych zawodników.
    The players who played in the Polish football league in the interwar period were very versatile and talented, therefore they were also successful in other sports. The aim of the study was to assess the scale of this phenomenon. The mass development of football in Poland meant that there was a shortage of talented players in the struggle involving sports games, athletics or winter sports. The high level of physical fitness of the players predisposed them to participate in the competitions in sections of sports clubs other than football. The author presents detailed lists of footballers, participants in league competitions in the years 1927–1939, who became medallists of Polish championships in ice hockey, athletics, basketball, volleyball and handball. In addition, the biographies and achievements of the most versatile athletes are included.
