Background: Muscle strength as an element of preparation and sport competition is one of the most important aspects in technical and tactical efficiency. The aim of this study was to define the level of relation between bioelectrical muscle activity and isokinetic strength parameters in 17-19-year-old judoists.Material/Methods: 30 judo athletes (17-19-year-old) took part in the research. The research was conducted in Gdańsk Academy of Physical Education and Sport Laboratory during 2006-2008. In the research authors used: to evaluate the isokinetic strength level, "Concept 2 Dyno" device was used in the research, along with surface summary electrical bio-potentials reading on EMG AMT-8 CDN BORTEC BIOMEDICAL with ACQ software.Results: In the upper right limb there are more statistical significant correlations between isokinetic strength parameters and electrical muscle activities.In the lower limbs measurement of the left leg shows more significant correlations.Conclusions: Comparing the upper and lower limbs, it was noticed that the isokinetic strength parameters of the upper limbs are more correlated with the measured muscle electrical activities.Regarding the left and the right side comparison, the right side (the upper and the lower limb) isokinetic strength parameters are more correlated with the measured muscle activities.

Coping with pain plays a very important role in human life and it may differ depending on the personality characteristics of patients such as their level of optimism. The aim of this study was therefore to determine whether the coping strategies for to cervical spine pain amongof office workers were determined by gender, the locus of pain control orand an optimistic attributional style. 30 office workers (Females = 15, Males = 15) took part in the experiment. The age of the participants was for females (M and for =43; SD=5.,9) and for males (M=44.,9; SD=4.,9. The subjects were asked to fill out 4 questionnaires: (CSQ), (BPCQ), (ASQ), a 10-grade visual analogue scale (VAS) and an original questionnaire. The study revealed that most of the office workers declare the ability to copeing with pain. Women were significantly more focused on emotions as a pain coping strategy than were the males participants. It was also shown that the internal locus of pain control significantly correlates with coping focused on problem solving. Participants characterized by anwith optimistic attributableional style used task oriented strategies more often than did the pessimists. There were no significant differences in the level of perceived pain between optimists and pessimists. It was foundind that there are statistically significant differences in coping with pain coping according to gender. Women were significantly more focused on emotions as a pain coping strategy than were the males participants. A high level of optimism may have a significant impact on the reduction of emotion - oriented strategies such as catastrophising by switching on more beneficial strategies to cope with pain by the individual. There are no significant differences in the level of perceived pain between pessimists and optimists.

Background: Until now, analyses gave no information about the numerous quantitative parameters that might affect the level of performance of a group composition. The research was undertaken with a more advanced computer program to analyze competitive performance using the performance parameters such as space parameters, running path, throwing distances, movement network, arrangement forms, etc during the 2008 Baltic Rhythmic Gymnastics Cup (Senior) in order to find which quantitative and qualitative criteria distinguish the performance of the best teams.Material/Methods: Videos from the Baltic Rhythmic Gymnastics Cup 2008 in Poland were analyzed. In the final analysis results of national teams from Poland, Georgia, Azerbaijan, Japan and Lithuania were taken into consideration. Each team included 5 participant plus one substitute, aged 16-25 (senior group), practicing rhythmic gymnastics for 11 years. Participants executed 2 routines performance: with ropes and with hoops and clubs. The computer software "SIMI Scout" developed by University of Magdeburg in co-operation with the firm SIMI GmbH Munich was applied.Results: For the evaluation of results, data are summarized and considered logically by groups. The first group documents is the spatial behavior of 5 gymnasts in the competition area. The second group contains data on selected difficulties, such as mobility elements, waves, turns, balance elements and standing. In the third group, data are recorded for the behavior of the hand apparatus, for example, apparatus changes and distances covered by the hand apparatus without body contact. The fourth group gives an overview of the degree of difficulty of the techniques in different categories, while the fifth group contains data on the synchronicity of motor actions.Conclusions: The number of formation parameters, the throws parameters, the number of artistic elements parameters and the catch parameter can be considered as important criteria in the ropes performance of the group competition.This research failed to show any important criteria in the clubs and hoops performance of the group competition.

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.

Background: Hyperbaric therapy is a relatively new non-invasive therapeutic method. It involves inhaling the patient with pure oxygen using a pressure of 2 to 3 absolute atmospheres (ATA). The main purpose of this therapy is to improve the healing mechanisms and repairing processes in the case of various types of wounds and diseases. While in medicine this method is quite popular, in sport it is rarely used today and if so than mainly for the purposes of faster return to full fitness of athletes after injuries or after heavy, intense training conditions. Case study: Two subjects took part in the experiment. Training sessions were performed based on the selected original set of exercises within 29 days. Experiment participant was under conditions of increased pressure (2.5 ATA), during the session he breathed 100% oxygen, provided by the individual respiratory system. The measurement of muscle strength level of selected muscle groups, in selected motor tasks was estimated in (maximum weight – which is the maximum external resistance defeated in one repetition). It was found that there were increases in the level of muscle strength in selected muscles groups in first participant as a result of the applied set of exercises (motor tasks) and the effect of the hyperbaric sessions. Conclusions: The results of the study show that there was a visible/significant influence of the hyperbaric session on increasing the muscle function based on strength training example. This method in combination with adequate strength training sessions could be used in many areas connected with psychomotor development of human abilities.
