The Morasko strewn field located near Poznań, in Poland is an excellent example of well preserved strewn ellipse with several small hypervelocity impact craters. Although many studies on this crater field has been conducted since the first meteorite finding in 1914, the discussion of the strewn ellipse, its shape, size and direction is still ongoing. The proper answers on many questions concerning the Morasko impact can be given by numerical modeling. In this paper the implications of the Morasko meteoroid entry parameters on the observed strewn ellipse are presented. It is shown by numerical modeling, that the Morasko impact occurred from the NE direction, with the shallow horizontal angle. The strewn ellipse size is modeled together with the number of big meteorites which probably remain in the Morasko reserved area deep in the ground. The results described in this paper clearly indicate that the strewn ellipse related to the Morasko fall is elongated no more than several kilometers and contain over a dozen meteorites weighting more than 100 kilograms.

Althought the first Morasko meteorite has been found over 100 years ago, the discussion about the Morasko strewn field and cratersis is still ongoing. In this paper, the revision of existing opinions on the Morasko craters formation and origin is conducted regarding to numerical modeling results and current knowlage about impact cratering procssess.

Introduction. The aim of this study was to find the opinions of the representative groups of Poznan citizens about the introduction of traditional games as a "new" option to activate youngsters and adults physically. Material and methods. The data were collected by interviews on three selected groups: 1. headmasters and principles of kindergartens and pre-school and early school teachers (n=51); 2. parents of pre-school and early school children (n=200); 3. retired people - seniors having grandchildren (n=103). Results. The obtained results revealed the low knowledge and awareness of traditional games among examined people. The majority of the examined people fully agreed that a Traditional Games Park would be a different offer from other ones concerning physical activity in urban areas. More than a half of them declared they would willingly take their tutees to this kind of park on numerous occasions if various educational and recreational programmes and offers were provided. Conclusion. This kind of park might be the right place to show other inhabitants of Poznan and its visitors a part of regional and national culture and history and also to give people the chance to explore our social life of the past and to carry it playfully and peacefully into the future.

Study aim: the purpose of the present study was to investigate the potential of traditional games as a method of increasing the physical activity (PA) of women following mastectomy. A cross-sectional survey during the 20th ONCO Games was conducted and the sample included data from women divided into two groups: up to 50 years old (n = 26) and over 50 years old (n = 86). Material and methods: PA was assessed using a questionnaire, and the number of steps taking during 30-minute periods was measured using pedometers during each of the games. Exertion was evaluated using Borg’s Scale. Results: there was no difference in levels of coherence between the age groups. The group of younger women were statistically more active (M = 3.34 days/week) than the older group (M = 2.77 days/week). All the games were evaluated to be of light intensity, with ringo perceived as being statistically more fatiguing in the over 50 age group. The highest number of steps was performed during the game of ring-net-ball (M = 1903 steps/30 min) in both age groups, with older women performing statistically more steps. Similar situations were observed in the cases of pétanque and speedminton. In ringo, the situation was reversed. The lowest number of steps was recorded in pétanque in the younger age group (M = 296 steps/30 min). Conclusion: this study indicates that in the rehabilitation and recovery process after mastectomy, traditional games could be a bridging link between exercising and sports as they provide not just activity but also a unique and valuable social context.

Health deteriorates with age due to hormonal changes and reduced physical, mental and social activity. In turn, this deterioration can lead to a wide range of problems including a fear of undertaking any forms of physical movements. Reports from exercise-based studies indicate there might be considerable improvement with appropriately programmed exercise workloads. However, the lasting effect of such programmes seem to be doubtful as a lot of the elderly drop out along the way, sensing it to be too "organized" and too stressful. Therefore, we claim that some traditional games, as a form of physical activity, can serve its role in engaging elderly adults. They do not require high level of specialization and technical perfection and may also be useful as a form of physiotherapy, particularly with elderly individuals who suffer age- and health-related problems.Play as a form of physical, playful activity is essential for healthy development of any individual as it seems to facilitate the linkages of language, emotion, movement, socialization and cognition. As a movement activity, it is a rather free-spirit activity that makes a positive difference in brain development and human functioning. Although rooted in biological aspects of life, play needs to be associated with cultural aspects of human development. Especially with the elderly population, this social and also cognitive stimulation is sometimes more important than physical. So in our paper we ask: what potentially positive effects can a traditional play/game have on the elderly people?Since there has been no research on the health-related effectiveness of such games, in this article we will highlight this problem from a number of different angles as a proposal for various community-based exercise programmes. This will allow us to design and adapt those games, specially to the health needs and social interests of this particular section of the population. It is also meant to serve as a proposal for potential future research.

Study aim: To assess the intensities of three types of physical education (PE) classes corresponding to the phases of the teaching/learning process: Type 1 - acquiring and developing skills, Type 2 - selecting and applying skills, tactics and compositional principles and Type 3 - evaluating and improving performance skills.Material and methods: A cohort of 350 schoolchildren, aged 13 years, from 3 selected urban schools in Poznań participated in the study. A total of 202 PE lessons was involved using heart rate (HR) monitors, one randomly selected subject per every class. Four intensity zones were assumed (<140, 140 - 159, 160 - 179, ≥180) and exercising time spent within each zone was measured.Results: Type 2 classes induced the most pronounced cardio-respiratory responses irrespectively of the kind of sport activities thus enhancing the cardio-respiratory fitness.Conclusions: Type 2 activities ought to be taken into consideration when designing PE curricula in order to avoid long runs of inadequate physiological stimuli.
