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 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

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.
