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.

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 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 In order to avoid hypoglycaemia, individuals diagnosed with type 1 diabetes usually limit their physical activity, which might lead to changes in somatic build and in the level of muscle strength. The aim of the study was to define somatic build, hand grip strength and physical activity in patients diagnosed with type 1 diabetes. Material and methods The study included 24 patients with type 1 diabetes and 24 healthy individuals. Body build was assessed on the basis of 20 somatic features and indices. Somatic types were assessed using the Sheldon's method modified by Heath-Carter. Hand grip strength was measured with hand grip dynamometer, while physical activity was evaluated by means of a questionnaire survey. Results The results obtained from female subjects showed insignificant intergroup differences concerning the measured features. Endomorphy was a predominant component among female somatotypes. Compared to the healthy controls, males with type 1 diabetes exhibited lower values of arm circumference (tensed), thigh circumference, ankle width and mesomorphy as well as hand grip strength (p<0.05). The diabetic patients preferred cycling while healthy people opted for combat sports. Conclusions Differences in somatic build, hand grip strength and physical activity between healthy individuals and patients diagnosed with type 1 diabetes were greater in the case of men than women. Compared to healthy individuals, diabetic men exhibited lower values of somatic features that are typical of mesomorphy and muscle strength. Both women and men diagnosed with type 1 diabetes preferred low-intensity and aerobic physical activity.
