posterior displacement of the projection of the center of gravity of the lenth of approximately 4 mm in late pregnancy comparing to the beginning of pregnancy. The displacement may be the result of the body's adaptation to the increased mass in the anterior trunk area in late pregnancy. No discrepancy was found when comparing the average center of gravity location in the early pregnancy and after delivery.We concluded that the change of the center of gravity location in late pregnancy is temporary and two months after delivery the vertical projection of the center of gravity is located as it was at the beginning of pregnancy.

Minnesota Leisure Time Physical Activity Questionnaire as an additional Tool in Clinical Assessment of Patients undergoing Percutaneous Coronary Interventions The aim was to analyze the usability of Minnesota Leisure Time Physical Activity Questionnaire (MLTPAQ) in assessment of physical activity in patients before and 6 months after percutaneous coronary intervention (PCI). The study group consisted of 211 patients aged between 34-79 years (x = 59,5±7,89 yeras), with history of ischemic heart disease (IHD) with or without previous incidence of myocardial infarction (MI). The MLTPAQ was administered to all patients at the time of PCI and then 6 months later, as was the treadmill stress test (TST) and echocardiography (ECHO). Total energy expenditure calculated with the MLTPAQ remained at the same level and was of low intensity (<4 MET, <2000kcal/week) 6 months after the PCI. There was an increased physical capacity noted 6 months after initial PCI: increased metabolic cost (MET); maximal oxygen uptake (VO2max); maximal heart rate (HRmax) obtained during the TST and decreased resting heart rate (HRrest). ECHO examination showed improved LVEF%. Despite increased physical capacity and improved heart hemodynamics, resulting most likely from PCI procedure, the patients showed a similar level of leisure time physical activity 6 months after the PCI.

Introduction. The aim of the study was to assess the effects of 4 months of karate training on the body composition of advanced males and females and its comparison from the preparatory and start period with the results of a control group. Material and methods. The study covered 18 kyokushin karate contestants (9 females, 9 males) from a Polish karate kyokushin club (R-research group), mean age of 22,8±4,9 years (18-33), mean BMI of 23,3±2,20 [kg/m 2 ] (19,6-27,5), mean number of years of experience of 8,3±3,36 years (5-16) and 20 individuals (10 males, 10 females; C-control group)-performing up to 1 hour of physical activity per week, mean age of 24,5±3,39 years (22-33), mean BMI of 24,1±2,71 [kg/m 2 ] (20,4-29,8). Two measurements of the body composition of athletes were made with the use of: OMRON BF 306 and BODYSTAT 1500 devices. Results. The study results show no statistically significant change in body composition in women who participate in kyokushin karate training between the first and second measurement (p>0,05), in turn, such changes were demonstrated in men when analyzed by BODYSTAT 1500: the percentage of fat mass was lower and fat free mass was higher after preparation period (p<0,01) and the percentage of total body water was higher (p<0,05). Anthropometric characteristics of athletes surveyed in both preparation and start periods show no significant differences (p>0,05). Conclusions. Anthropometric factors, type of body building, body mass index and body composition are all of great importance in a highly qualified sport like the karate. However, the large number of measurement tools, questionable repeatability of tests conditions and differences found between the sexes or ethnic discrepancies makes the evaluation and comparison analyzes of selected anthropometric indices and body composition rather difficult.
