Background: The aim of the study was to determine additional effects of 8 weeks’ whole body rotation vibration combined with a fitness exercise program of health-related training on chosen motor coordination abilities and flexibility in young females. Material/Methods: Thirty-seven young females aged 20-25 (students) voluntarily participated in the study. The training program included 24 training sessions which were performed over the course of 8 weeks (3 sessions a week) and was based on basic principles of health-related protocols. The program of sessions was performed by subjects of the experimental group with a working whole body vibration platform (20 Hz), whereas those of the control group performed the same exercises with a non-working (placebo) vibration platform. Chosen motor coordination abilities (body balance, reproducing of strength and whole body rotation angle) and flexibility (active and passive) were measured at the 4th and the 8th week. Results: This study showed additional effects of concomitant whole body vibration and physical exercises for 24 sessions of training (40-50 min). A significant increase in some values of the motor coordination ability (body balance, reproduction of strength and angle in rotation) and hip active and passive flexibility was shown in the experimental group vs. the control one. Conclusions: The results indicate that chronic rotation whole-body vibration, as an accompanying impact to a fitness exercise program, has additional positive effects on coordination and flexibility in young females.

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.

Aim: Under the supervision of the Department of General and Vascular Surgery of Poznan University of Medical Sciences, a questionnaire was distributed online or as a paper version to medical students (MSs) in order to better understand the attitudes towards surgery as a specialty and to determine the reasons why students do and do not choose vascular surgery as their career path. Materials and methods: The questionnaire was distributed online or as a paper version to MSs in the 3rd, 5th, and 6th year of the PUMS 6-year M.D. program. It provided the data on the year of study, grade point average (GPA), sex, age, respondent’s specialty choice, 33 questions with responses on a 1-5 Likert scale (1 was the least important reason and 5 was the most important reason), and 2 questions with socres between 0 and 4. A total of 136 Polish MSs of PUMS completed the survey. Results: For MSs who choose vascular surgery as their career path, “endovascular capabilities of vascular surgery” and “higher income possibilities than a general surgeon” were the most important reasons. The “poor availability of work in other places than the vascular surgery department of your choice, few such clinics in the region” was the most important reason not to choose vascular surgery. A role of gender was also noted - 13% of male MSs classified gender as an “important factor”, in contrast to 60% of female MSs. Conclusions: The findings of this study might help to develop better strategies to attract future trainees to surgical specialties, particularly vascular surgery, and improve work environment.

Background. A properly composed diet is one of the key elements favorably affecting exercise capacity in athletes. Athletes increasingly often complement their diet by including dietary supplements in it. Due to the risk entailed by improper supplementation, it is justifiable to monitor supplement consumption. The aim of the study was to assess the consumption of dietary supplements by female football players at a competitive level of athletic performance. Material and methods. The study was conducted in a sample of 44 female football players, training at three league levels: ExtraLeague, I-League and II-League. The questionnaire included the questions about the period of training, diets, self-assessment of the participants’ knowledge on nutrition and supplementation. Additionally, measurements of body height and body mass were taken. Results. The sample included women aged 20.5±5 years; the subjects body height and body mass were 167.2±5 cm and 61.6±10.1 kg respectively and they trained on average 5 years or longer. 20.5% of the survey respondents reported taking dietary supplements, most of them (67%) within the period shorter than six months. The most frequent reported reasons for supplementation were: the desire to improve exercise capacity and/or someone’s recommendation. Most of the respondents (65%) reported a favorable effect of dietary supplementation. The football players learned about supplementation from their dieticians and/or the mass media. Conclusions: The female football players usually used supplements consciously and took only those with the effect confirmed by study results. Dietary supplements were usually taken with caution and the sources of knowledge of the supplements were in most cases reliable.

Wstęp. Właściwie dobrana dieta jest jednym z kluczowych elementów wspomagania zdolności wysiłkowych sportowców. Sportowcy coraz częściej uzupełniają swoją dietę spożywając suplementy diety. Z uwagi na zagrożenia płynące z niewłaściwej suplementacji, zasadne jest jej monitorowanie. Celem pracy była ocena stosowania suplementów diety przez kobiety trenujące zawodowo piłkę nożną. Materiał i metody. Badanie przeprowadzono z udziałem 44 kobiet trenujących zawodowo piłkę nożną na 3 poziomach ligowych: ekstraligi, I ligi i II ligi. W ankiecie zadano pytania o staż treningowy, stosowanie diet, samoocenę wiedzy żywieniowej oraz suplementację. Dodatkowo dokonano pomiaru wzrostu i masy ciała. Wyniki. Badaną grupę stanowiły kobiety w wieku 20,5±5 lat, o wzroście 167,2±5 cm i masie ciała 61,6±10,1 kg, o stażu treningowym 5 lat lub więcej. 20,5% respondentek spożywało suplementy diety, w większości (67%) przez okres krótszy niż pół roku. Powodem suplementacji była przeważnie chęć polepszenie zdolności wysiłkowych i/lub zalecenia osób trzecich. Większość respondentek deklarowała pozytywne działanie suplementów diety (65%). Piłkarki czerpały przeważnie wiedzę na temat suplementów od dietetyka, trenera i/lub środków masowego przekazu. Wnioski. Piłkarki zazwyczaj prowadziły suplementację profesjonalnie, spożywały suplementy o potwierdzonym badaniami działaniu.

Introduction: The aim of the study was to examine relationships between power of the lower limb and agility, speed, and change of direction (COD) deficit in professional female soccer players. Material and methods: Thirty-three elite Polish Extraliga league soccer players (aged 22 ±5 years; body height 166 ± 4 cm; body weight 58 ± 8 kg) performed the following fitness tests: lower limb muscle power (Leg Press, Half Squat, Counter Movement Jump), straight linear speed (SLS 20 m), and COD speed ( Zig-Zag test, COD deficit). Using the median value as a reference, the players were subdivided into two groups (n=17; n=16) according to their LP, HS 60% 1RM, CMJ (High values below median = stronger group and Low = weaker group ). Results: The COD deficit was calculated as the difference between the 20m speed and the Zig-Zag test. The stronger group was better than the weaker group in SLS 20m (p<0.05; ES=1.23; 0.83; 0.93), but in the Zig-Zag agility test, the difference in the results was not statistically significant (p>0.05; ES=0.48; 0.34; 0.34) and this affected the COD deficit, which was higher (p<0.05; ES=0.9; 0.73; 0.72). The most important finding was that the stronger group had a higher COD deficit and its improvement (reduction) occurs only if the results of the agility test are improved (through agility training) [Ydeficit All groups=0.10+0.87* 20m - 0.83* Zig-Zag]. Increasing power (HS, LP) lead to the improvement in SLS p<0.05, not to COD abilities. Conclusion: This can be useful for coaches during agility training and to improve COD deficit in soccer players and women in general.

Zespół mózgowego deficytu kreatyny jest zbiorczym terminem dla określenia różnych podtypów choroby, charakteryzującej się nieprawidłowym poziomem kreatyny w ośrodkowym układzie nerwowym. Jeden z nich, deficyt transportera kreatyny związany z mutacją w genie SCL6A8, jest częstą przyczyną niepełnosprawności intelektualnej związanej z chromosomem X. Typowo mutacja ta ulega pełnej ekspresji u pacjentów płci męskiej, jednakże kobiety również mogą prezentować niektóre z objawów, takie jak niepełnosprawność intelektualna w stopniu lekkim, problemy z uczeniem się i zaburzenia zachowania. Pacjent przedstawiony w poniższym opisie przypadku to 4-letnia dziewczynka ze zdiagnozowanym deficytem transportera kreatyny. U dziewczynki przeprowadzono diagnostykę genetyczną, w której zaobserwowano nieopisaną dotychczas w literaturze mutację w genie SCL6A8, oraz wykonano spektroskopię rezonansu magnetycznego, która wykazała typowy, nieprawidłowy poziom kreatyny w centralnym ukladzie nerwowym. Pacjentka prezentowała opóźnienie rozwoju mowy oraz rozwoju ruchowego, łagodną niepełnosprawność intelektualną, zaburzenia zachowania oraz napady padaczkowe dobrze kontrolowane kwasem walproinowym. Rokowanie i stworzenie planu diagnostycznego u pacjentki z deficytem transportera kreatyny stanowi duże wyzwanie kliniczne z uwagi na niewielką ilość danych literaturowych dotyczących pełnej ekspresji tej mutacji u kobiet. Nowe metody terapeutyczne mogą przynieść obiecującą zmianę dotyczącą prognozy dalszego rozwoju i kontroli napadów u osób z deficytem transportera kreatyny obojga płci.

Cerebral creatine deficiency syndrome is a collective term including different types of disease, all characterised by abnormal creatine level in central nervous system. One of the types, creatine transporter deficiency, is a common cause of X-linked intellectual disability. Typically, it is fully expressed in male patients, however females can also present some symptoms, such as mild intellectual disability, learning difficulties and behavioural problems. The patient presented in this case report is a 4-year-old girl, diagnosed by genetic testing with creatine transporter deficiency showing a novel mutation in SCL6A8 gene, and by proton magnetic resonance spectroscopy in which she presented a typical abnormality in creatine level in central nervous system. The patient presented speech and motor delay, with mild intellectual disability, behavioural problems and seizures well-controlled by valproic acid. The prognosis and therapeutic plan in a female patient with CRTR is a big clinical challenge, as there is few data about this mutation being fully expressed in women. The novel therapy methods may be a promising change in further development and symptoms control in patients with CRTR of both sexes.
