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.

Introduction. This paper discusses the relationship between the technique implemented during competition and the end result including an attempt to evaluate the technical and tactical preparation of different nationality competitors in Greco- Roman wrestling. The research was conducted during the 2009 Junior World Cup in Turkey. Material and methods. The research material included a video recording posted by the International Federation of Associated Wrestling Styles (FILA) on their website. The material contained recordings of 240 matches. An analysis of 212 matches with competitors from 49 countries was conducted; each team selected one competitor in each weight category (up to 8 competitors in total). Results and conclusions. During the competition there was strong correlation between victory and the execution of the roll-through and the combat zone and result defence, also in the ground position. Competitors from Russia and Iran, who were most successful, winning 6 and 4 medals respectively, obtained an average of 3.18 technical points in each match. Among the sample analysed this was the lowest score, indicating the optimal use of technical and tactical skills by the competitors resulting in a victory.

Background: The purpose of this work is to determine the correlation between the indexes of the special fitness test and the parameters of aerobic and anaerobic capacities of women judo competitors during the preparation to the competitive period.Material/Methods: In the research presented in the paper the level of aerobic and anaerobic capacity and the results of a special mobility fitness test of female judo contestants, either members of the Olympic and National Teams or their immediate reserves, was determined (n=11). In order to assess the aerobic capacity a test with increasing load until the refusal to continue the test was applied, while the anaerobic capacity was assessed thanks to the application of 30 seconds Wingate Test with a load on lower limbs. Within the framework of the assessment of special mobility fitness, the Special Judo Fitness Test (SFJT) was applied.Results: An analysis of correlation between the anthropometric indices and SJFT indices was carried out; besides that a correlation between the indices of aerobic and anaerobic capacity and the results of the special mobility fitness test were analyzed.Conclusions: On the basis of analysis of the empirical material it was determined that the indices of special mobility fitness test clearly correlated with the relative values of indices that characterized the aerobic and anaerobic capacity. A lower level of indices of aerobic and anaerobic capacity in comparison with results obtained by other authors was observed, while the indices diagnosing the level of special fitness of female judo contestants had a higher value.

Background: 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.Material/Methods: 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.Results: 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.Conclusions: 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.

Study aim: To find out whether a 6-week creatine supplementation would significantly augment body mass and muscle circumferences in male bodybuilders.Material and methods: A group of 14 male bodybuilders aged 16 - 29 years were randomly divided into two groups: experimental (E) and control (C), 7 subjects each. Group E received creatine monohydrate, Group C - placebo, 10 g daily for 6 weeks without saturation phase. The experimental design was a double-blind one. All subjects were on strictly controlled diet, the daily intakes amounting to 2.3 - 2.8 g of protein, 1.0 - 1.2 g of fat and 5 - 6 g/kg body mass of carbohydrate, and 3200 - 4000 kcal. All subjects trained 3 days a week, each session lasting 120 min, in the ‘Power, Rep-Range, Shock’ mode. Chest, waist, arm, forearm, thigh and calf girths were measured in the relaxed and contracted states, together with body mass, before and after the study.Results: Significant, training-induced changes were noted in almost all body circumferences studied in both groups and muscle states, those in the chest, biceps and thigh girths being the most pronounced ones and significantly (p<0.05) greater in the experimental than in control group in the contracted muscle state. In the relaxed state the between-group differences were significant for the chest and thigh girths. The increments in body mass were significantly (p<0.01) higher in the experimental than in control group (4.3 ± 1.3 and 2.1 ± 0.7 kg, respectively).Conclusions: The observed changes may have been brought about by creatine administration.

Background: 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.Material/Methods: 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).Results: 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.Conclusions: 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.
