Purpose. Female runners typically suffer more from chronic running injuries than age-matched males, although the exact biome-chanical mechanisms behind the increased susceptibility of female runners are unknown. This study aimed to compare sex differences in tibiocalcaneal kinematics during the stance phase of running. Methods. Twenty male and twenty female participants ran at 4.0 m · s–1. Tibiocalcaneal kinematics were measured using an eight-camera motion analysis system and compared using independent samples t tests. Results. Peak eversion and tibial internal rotation angles were shown to be significantly greater in female runners. Conclusions. based on these observations, it was determined that female runners may be at increased risk from chronic injury development in relation to excessive tibiocalcaneal motions in the coronal and transverse planes.
The authors report an unusual case of a 15-year-old boy who dove into a shallow lake and suffered a cervical fracture of C5 affecting the spinal cord. This resulted in tetraplegia. Vitamin D3 deficiency and a history of several bone fractures supported an idea that the patient's bone structure had been weakened. The deep vein thrombosis of lower limb and neurogenic heterotopic ossification of a hip limited the effectiveness of physical therapy.

The aim of this study was to identify the morphological configuration of youth athletes from professional soccer clubs and to verify their differences according to the tactical position on the field. Overall, 67 male players aged 15 to 17 years were evaluated. The examined anthropometric measurements included body mass, body height, skinfolds (triceps, subscapular, supraspinal and medial calf), girths (flexed and tensed arm and calf) and breadths (humerus and femur). For statistical purposes, analysis of variance and post hoc Bonferroni and Kruskal-Wallis tests were used. We concluded that goalkeepers were heavier and taller than center backs (p = 0.015 and p = 0.001), midfielders (p = 0.005 and p <0.001) and center forward players (p = 0.024 and p <0.001). The average somatotype for defense, forward and goalkeeper positions was a balanced mesomorph. Midfield players showed ectomorphic-mesomorph characteristics. It was concluded that goalkeepers were characterized as being taller and heavier and that somatotype features of athletes were similar between positions, except for midfield players
The novel Umělohmotný třípokoj by Petra Hůlová is a story of a thirty-year old prostitute working privately, who with calmness and through an emotionless monologue acquaints the reader with the world of her profession. The novel is rich in illustrations of how the boundaries of womanhood and manhood frequently function in culture. The way that literature perceives the roles and attributes in Hůlováʼs book was confronted with the feminist thoughts and the gender reflection in the postmodern cultural discourse. By drafting borders between both sexes, the author implies that they confine the women and the man within structural frames that are impossible to break by human mind and mentality. The most visible example is the main character of the novel who breaks out of the model of a prostitute dependant on men by posing as an independent woman. In fact, she becomes trapped within new borders fixed by the contemporary world.
This paper analyzes the issue of gender problems, the process of genderization of the personality, the gender socialization. Despite the transformational trends, contemporaryUkrainian society is characterized by gender stereotypes. The different points of scholars’ views about the lack of harmonious relations among school age children are analyzed. The necessity of using gender component in the educational process is defined. It is pointed out that in the process of gender socialization, which provides a person’s awareness of their sexual independence and behavior throughout life according to it, the most effective are the mechanisms of imitation and identification. Starting with coping the behavior of their parents (girls trying to be more like the mother, the boys – like father), the child moves on, choosing new examples of gender behavior both real and unreal (the book characters, the heroes of fairy tales and so on). The suggestion of gender norms is often used by society as a means to influence individuals. So, in a society often evoke gender stereotypes and standards of conduct, that are not based on logic and not explaining the reasons for their imitation. It is noted that modern society is undergoing fundamental changes, providing the need for further development of the gender approach in pedagogy, as well as providing targeted development of youth gender culture. Among these changes are: converting egalitarism in one of the priority directions of the state policy of the majority of countries in the world, forcing a rethinking of the role and place of women in society; changing cultural stereotypes of masculinity and femininity, loss of polarity; scrapping the traditional system of gender stratification, easing stiffness in the definition of male and female social roles, the elimination of normativityin the traditional gender division of labour; changes in gender characteristics of marriage and family relations:acquisition of new high-quality properties: activation of marriage and family egalitarization; mutual contribution of men and women in their wellbeing; the spread of consensual, business forms of marriage and serial monogamy; objective changes in marriage and family status of modern women: reduction the role of the family as the traditional value for her, the growing importance of the values beyond the family (education, career, prestige, financial income and so on), focus on the one child or even on childlessness; objective changes in marriage and family status of the modern man: the loss of the traditional «breadwinner», the reduction of socializing role of fatherhood;deepening of the general tendency of family relations on the change of value orientations, in the centre of which is the family group and the individual;reorientation of the process of formation of the child’s personality with traditional, clearly fixed gender behaviors in mixed or inversive model that has significant negative consequences for society.
INTRODUCTION: Obesity and metabolic syndrome are increasingly common in the adult population. There is a well- -known relationship between those two conditions and cardiovascular diseases; nonetheless, not much is known about how obesity and metabolic syndrome affect bone metabolism and fracture risk. The study aimed to assess the parameters of bone metabolism, as well as assess their relationship with the risk of fractures in obese men with central obesity and metabolic syndrome, and to compare the obtained results with those of healthy controls. MATERIAL AND METHODS: The study involved 36 obese men (body mass index – BMI ≥ 30) with central obesity (waist circumference – WC ≥ 94) and 10 healthy men as controls, aged 54–77. The FRAX (Fracture Risk Assessment Tool) calculator was used to measure the 10-year fracture risk. The levels of bone metabolism markers osteoprotegerin (OPG), C-terminal telopeptide (CTX1), and fibroblast growth factor 23 (FGF-23) were determined in the patients. RESULTS: The FRAX parameter was significantly lower (p < 0.001) in the obese men when compared to the controls. A significant negative correlation between FRAX and BMI (p < 0.001) was observed in the obese men, but not in the healthy subjects. There was also a negative correlation between FRAX and WC (p < 0.001), again only among the obese subjects. A positive correlation (p < 0.01) between FGF-23 and FRAX was found in the non-obese group. CONCLUSIONS: Obese men have a lower 10-years fracture risk compared to the healthy controls. Additionally, the increased BMI and waist circumference in the obese men were found to be associated with a reduced bone fracture risk, whereas no similar relationship in controls was observed. Moreover, higher FGF-23 levels in the healthy males was correlated with an increased 10-year fracture risk.

WSTĘP: Otyłość oraz zespół metaboliczny coraz częściej występują w populacji osób dorosłych. Powszechnie znany jest związek wymienionych zaburzeń ze zwiększonym prawdopodobieństwem wystąpienia chorób układu sercowo-naczyniowego, jednakże mniej oczywisty jest ich wpływ na metabolizm kostny oraz ryzyko złamań. Celem badania była ocena parametrów metabolizmu kostnego, ich związku z ryzykiem złamań u otyłych mężczyzn z otyłością brzuszną oraz zespołem metabolicznym, a także porównanie uzyskanych wyników z wynikami osób zdrowych. MATERIAŁ I METODY: W badaniu wzięło udział 36 otyłych mężczyzn (body mass index – BMI ≥ 30) ze współistniejącą otyłością trzewną (obwód talii – waist circumference – WC ≥ 94) oraz 10 zdrowych mężczyzn z grupy kontrolnej, w wieku 54–77 lat. Do oceny ryzyka złamań zastosowano kalkulator FRAX (Fracture Risk Assessment Tool). U pa-cjentów oznaczono stężenia markerów metabolizmu kostnego: osteoprotegeryny (OPG), C-końcowego usieciowanego telopeptydu łańcucha kolagenu typu I (CTX1) oraz czynnika wzrostu fibroblastów 23 (fibroblast growth factor 23 – FGF-23). WYNIKI: U osób otyłych FRAX był istotnie niższy (p < 0,001) niż w grupie kontrolnej. Zaobserwowano ujemną korelację między FRAX i BMI (p < 0,001) u otyłych mężczyzn. U zdrowych osób taka korelacja nie wystąpiła. Jedynie u osób otyłych stwierdzono również ujemną korelację między FRAX i WC (p < 0,001). Obecnej w grupie osób zdrowych pozytywnej korelacji (p < 0,01) między FGF-23 i FRAX nie obserwowano u otyłych mężczyzn. WNIOSKI: U otyłych mężczyzn stwierdzono mniejsze 10-letnie ryzyko złamań w porównaniu z osobami zdrowymi. Dodatkowo wykazano, że w grupie pacjentów otyłych większe BMI oraz obwód talii wiązały się z mniejszym ryzykiem złamań kości, natomiast u osób bez otyłości taka zależność nie występowała. Ponadto u zdrowych mężczyzn większe stężenie FGF-23 było skorelowane ze zwiększonym 10-letnim ryzykiem złamań.
