Contemporary anthropological research confirms the fact that body composition is one of the elements differentiating athletes from persons not practising sport systematically. The differences in body composition - in many cases even extreme - also regard athletes in the context of the sports discipline they practise.The aim of the study was to determine the properties of body composition of the Polish national team pentathletes in comparison to persons of the same population not practising competitive sport.The research comprised members of the Polish national team in modern pentathlon (n=10). The subjects were 18-23 (20±1.5) years of age with their body mass from 64 to 80 kg (73.27±6.1) and body height of 172-188 cm (180.11±6.22). The athletes had had 6-13 years (10.38±2.07) of training experience. Students of Warsaw Technical University (Poland) constituted the reference group. Measurements of 20 basic somatic features were made. The following indices were calculated: leanness, Rohrer's, BMI, Manouvrier's and pelvic-shoulder. Body density, total body fat, active tissue, the general body composition profile and internal proportions of the body composition were determined. An analysis of internal proportions of the factors of athletes' body composition revealed differences in particular groups of features. The athletes' overall body size results from greater than mean values of the body height and the average ones of stoutness and the fat content.The proportions of features within the analysed factors proved a significant advantage of the upper limb over the lower one and the significant predominance of the musculature of the forearm.

The aim of this study was to define the relationships between different kinds of muscle strength manifestations and technical skills (selected throwing techniques) in 17-19-year-old judoists. Results of measurements taken in 2006-2008 at the Physical Effort Lab in the Gdansk University of Physical Education and Sport were taken under consideration. 30 male judo athletes (17-19-year-old) participated in the study. They all were students of Comprehensive Sports School - with the judo profile and athletes representing clubs from Pomerania and Warmia-Masuria Provinces. An ergometric device "Concept 2 Dyno" was used in the measurements of isotonic strength and strength endurance. In the measurement of static strength an electronic dynamometer ERGO METER was used. To evaluate the level of technical skills (throws), the method of expert evaluation was used (coach evaluation).Using regression analysis results, which revealed the most significant relationships between variables presented in percentage value, relation's topographies of particular types of muscle strength were created. They form an applicable, transparent and ready-to-use in training process form for coaches. They point to these elements of strength preparation on which the training process should be primarily focused and during measurement intervals as well. Interpretation and synthesis of the results showed relationships of 10 technical skills (throws) with muscle strength in 17-19-year-old judoists in three out of four types: isotonic strength, strength endurance and static strength. These skills were included in hand throws - 2, foot - 1, hip - 3 and sacrifice - 4. Jump force remained with no significant relationships. The results of this study can be used in the training process of 17-19-year-old judoists. Following technical skills (throws) were characterized: tai-otoshi, seoi-nage, kosoto-gari, uki-goshi, tsuri-goshi, ushiro-goshi, tani-otoshi, osoto-makikomi, yokootoshi, yoko-guruma.

The subject of the paper is pro-health behaviour of women (N=477) who have children (N=124) and those who have no children (N=353). The Theory of Planned Behaviour (TPB) by Icek Ajzen, in the light of which the differences in the health behaviour level of the sample group are considered, constitutes the theoretical basis of this work.The research group consisted of women at the age of 19-36 (M=27, 5 yrs of age SD=4 yrs of age). The Health and Behaviour Survey Questionnaire by Steptoe and Wardle was used for the measurement. Four scales of healthy behaviour values, i.e., taking up physical activity, avoiding addictions, hygienic and medical behaviour and nutritional habits were analysed.As a result of the comparison, it appears that childless women demonstrated a significantly higher physical activity level (M=263.03) compared to women who have children (M=170.58) at the significance level (p=0.001). As far as the hygienic and medical behaviour is concerned, a significantly higher level was observed in the group of women who have children (M=261.15) than in the group of childless women (M=231.22) at the significance level (p=0.037).Further research should focus on the determination of the influence of subjective norm change (knowledge) on the health activities undertaken by women.

Background: The aim of the study was to establish preferential use of dietary, physiological and pharmacological supplementation by persons practising recreational bodybuilding and to check whether it results from the respondents’ knowledge or whether it is accidental. Material/Methods: The group of subjects comprised 100 persons practising recreational bodybuilding in four well-known Lodz gyms. In the study the method of a diagnostic survey was used. A questionnaire containing 31 closed and opened questions constituted the research tool. Results: It was demonstrated that the state of knowledge concerning dietary supplementation is insufficient, despite its optimistic self-assessment, and because of that the preferences as to the applied nutrients are inappropriate. The knowledge of physiological supplementation substances and preferences of their use seem appropriate, although the multitude of the mentioned means can attest to information chaos in this respect. Results of the poll seem to show that the problem of illegal pharmacological supplementation refers not only to professional sports but also, unfortunately, to recreation. Conclusions: It is recommended to conduct a widespread informative action among persons practising recreational bodybuilding to make them aware of dietary supplementation. The majority of respondents have a sufficient level of knowledge of means of physiological supplementation, and preferences of using them seem correct. Even though the state of knowledge concerning health complications hazards when taking prohibited pharmacological supplementation should be regarded as high, still the majority of the subjects (58%) do not reject the possibility of using it. Inconsistencies of attitudes among persons practising bodybuilding recreationally manifest themselves through simultaneous support for anti-doping tests and the desire to take advantage of unlawful pharmacological supplementation.
