Introduction. Training of children and young people is one of the most important stages and subsystems in coaching and determines future achievements of adult athletes. Level of physical fitness determines effectiveness of coaching and development of technical skills, influences the effectiveness of tactical actions and has an impact on current psychical disposition of a person. Aim of Study. The research presented herein focused on establishing trends in the changes of young fencers’ motor effects (their structure and level) in the period of 2006-2013 with reference to tasks aimed to comprehensively shape functional, fitness and technical foundations that take account of requirements set by a desired specialisation and regarded as typical for an oriented stage of sport training. Material and Methods. The study was based on the findings of research carried out 2006-2013 among young fencers – members of the Junior Team of the Greater Poland region (KWJ). The analysis involved a total of 200 boys aged 15 to 16. Measurements – designed to determine the level and structure of the fencers’ motor effects – were conducted by means of the International Physical Fitness Test. The test was also to assess basic somatic parameters, such as body height and weight, and to calculate the BMI. Results. The research found out that the general physical fitness of young fencers established on the basis of the International Physical Fitness Test – decreases in subsequent age groups. It may be a consequence of a regressive trend in intergenerational motor changes generally observed in the population, or relate to a change in height-and-weight proportions leading to an increase in body corpulence. Conclusions. A significant drop in strength related to overcoming one’s body resistance is most likely an outcome of the above-mentioned changes in the body structure. Therefore, as it appears, this fact should not be regarded as confirming a view that the so-called strong types of physical fitness are now more seldom among young people. A rise in endurance abilities in the period under research is a positive phenomenon from the point of view of fencing requirements, but also or even mainly – in the context of reversing the negative trend as regards lower general fitness of the young generation.
Introduction. Based on the kinetic chain model, in which the body is a linked system of interdependent and working in a proximal to distal order segments, the main task of the core is to stabilize the kinetic chain during functional movements. Poor core stability and muscle imbalance are factors that may contribute to injuries. By detecting imbalances, deficits and asymmetries in basic movement patterns, there is a tool which can provide the basis for the implementation of preventive strategies. Aim of Study. The main purpose of the present study is to verify the effectiveness of the corrective and stability exercises program on the quality of basic movement patterns among dance students. Material and Methods. The study was perform on 18 female students of first year of the Dance in physical culture from University of Physical Education in Poznan, Poland, who were divided into 2 groups: intervention (n = 9) and control (n = 9). In both groups, were carried out pre- and post-test. The quality of basic movement patterns was evaluated by the Functional Movement Screen, consisted of seven tests: deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push-up, rotary stability. In the intervention group was introduced the program of corrective exercises based on the obtained results enriched with core stability exercises. After 12-week training program, the quality of basic movement patterns were assessed again in both groups. Results. The research found out that at the pretest there was no significant differences between both groups. However, the groups differed significantly (p < 0.05) at post-test in terms of the overall result of the FMS and 2 tests: deep squat and in-line lunge. Significant posttraining changes were noted for the intervention group in the overall FMS scores and 4 tests: deep squat, hurdle step, in-line lunge, trunk stability push-up. Significant changes were also found in the control group in the overall FMS results and in the deep squat test. Conclusions. The identification of the “weakest links” of kinetic chain, integrated with properly planned and conducted corrective exercises, enriched with core stability exercises may positively impact on the quality of basic movement patterns, which seems to be the starting point for determining the possibility of used tool to prevent injuries.
Poszukiwania pachnicy dębowej Osmoderma eremita prowadzono na 17 powierzchniach badawczych w dolinie Wisły na Mazowszu w okresie od marca do listopada 2008 roku. Spośród przebadanych 749 wierzb w 427 (57%) stwierdzono dostępne próchnowiska, z czego w 73 drzewach odnotowano obecność larw, dorosłych osobników pachnicy dębowej lub ich szczątków. Uzyskane wyniki wskazują na możliwość istnienia nieopisanych dotąd w literaturze dużych populacji tego zagrożonego gatunku chrząszcza w głowiastych wierzbach w rolniczych krajobrazach nizinnej Polski
As a result of examinations carried out, 16 strains of microorganisms able to grow on mineral media with methyl tert-butyl ether as the sole source of carbon and energy were isolated. Bacteria prevailed among the isolated microorganisms . The growth of microorganisms under laboratory conditions was long and accompanied by low biomass increase. Under the conditions of the experiment, the isolated microorganisms did not show any quantitatively measurable biodegradability of methyl tert-butyl ether (MTBE) under aerobic conditions. This requires far-reaching caution with respect to trading in MTBE-modified petrols in order to protect the natural environment in Poland against contamination with that hard-to-biodegrade substance.
Over the last few years the interest for the so-called healthy lifestyle motivated by the fitness ideology has increased significantly. However, there is still little research concerning this question, especially with regard exercises in water. The purpose of this research was the comparison of the reason of women’s participation in different forms of physical activity such as aerobics and aqua aerobics classes, and whether the reasons for taking up this activity were related to health problems, place of residence or perhaps totally random. The research included 140 women who took part in 60-minutes long aerobics and aqua aerobics classes. The research was carried out by means of a statistical poll using a questionnaire. Among the main factors influencing the women’s decision to take up some kind of physical activity are: better life quality, lower stress level, better well-being, beneficial influence sports have on their health as well as improvement in physical appearance. It has been found out that regardless of the place of exercise, the motivation for taking up aerobics are similar for all women included in the research. The choice of place is motivated by their health capabilities and the environment they live in.
