Introduction Ageing processes are accompanied by degenerative changes within all functional and anatomical systems. These changes affect postural stability. This study sought to compare balance and fall risk indexes taking into account the age of the participants. Material and methods The study included female members (n=59) of the University of the Third Age (U3A) set up at the University of Physical Education in Warsaw. The participants were divided into five age groups: 1 (60-64 years), 2 (65-69), 3 (70-74), 4 (75-79) and 5 (>80). Biodex Balance System was applied in the study. The overall stability index (OSI), the anteroposterior stability index (APSI), the mediolateral stability index (MLSI) and the fall risk test were used in the analysis. The participants performed tests that involved standing on both feet with eyes open and closed on a stable surface as well as standing with eyes open on an unstable surface. ANOVA was used to assess balance with regard to age. U Mann-Whitney test was employed to compare groups in terms of balance and the fall risk (p<0.05). Results The oldest group demonstrated the worst balance performance with eyes open: OSI – 0.70±0.47; APSI – 0.49±0.30; MLSI – 0.37±0.43. The best values of balance performance were manifested by the subjects aged 65-69: OSI – 0.36±0.13; APSI – 0.25±0.08; MLSI – 0.18±0.11. Compared to eyes-open conditions, the tests performed with eyes closed revealed the smallest differences between the groups in OSI. The lowest fall risk was noted in groups 1 and 2. The highest fall risk index was found in group 4. Conclusions The findings of the study show that older adults depend on their vision when keeping balance. Physical activity exerts a positive influence on their balance and reduces the risk of falling. However, balance performance deteriorates and the fall risk increases with ageing.

Introduction. The increased level in competition and growing interest in sports for the disabled means that the training process of these people is the subject of studies and analysis. The main objective of this study was to identify the structure of the training loads in athletes with visual impairments in the 800 and 1500 m runs, in relation to sports performance. Material and methods. Seven annual trainings cycles of two groups (A, n=8, B, n=5) of athletes with visual impairments (medalists and participants of the Paralympic Games, World Championships, European Championships and multiple Polish masters), engaged in the 800 and 1500 m races, from the years 1998-2000 and 2003-2008 were evaluated. To analyze and evaluate the training loads, based on training logs two methods were used: Method I - based on an analysis of training documentation developed in the Department of Theory of Sport at the University of Physical Education in Warsaw. Method II - based on an assessment of the energy cost incurred for the implementation of training. Results. The analysis showed significant differences in the training process of the athletes of the two groups. The training of athletes from group A, was carried out mainly with the directed training method (61% of total load - TL) with low intensity - range 1 on a 5 point scale (74% TL), while group B - with special training method (76% TL) in second (2) range of intensity (71% TL). Conclusions. Training carried out by athletes from group B better reflects the specifications of middle distance runs, in comparison with group A, which could lead to a higher level of performance presented by the athletes of group B.

Introduction: Issues related to the classification in sport of people with disabilities is one of the major area of research in this field. Looking to objective criteria for assessing functional capabilities of the players, in order to allow them a fair competition, where impact on the achieved result is performance, and not the type and degree of disability. Material and methods: Analysis of the sports results obtained at the Paralympic Games (PG) in the years 2000-2012 was aimed to assess the classification system in Track & Field (TF). Material were sports results, based on official reports, obtained by athletes with locomotor disability (LD) in the track events during PG in the years 2000-2012. To determine the difference in results between starting classes the U Mann - Whitney test was used. Statistical significance was set at p <0.05. Results: The largest difference in the results obtained by the athletes (men) with similar functional capabilities was observed among competing on the wheelchair. No statistically significant differences between the results of the runners competing in the standing position was observed in T38 and T44 classes in 400m, throughout the entire period. A similar level of the results observed in women from T53 and T54 class practicing athletics sprint events. Conclusions: The specificity of the discipline that is the TF (a large number of events with various type of effort) can cause problems in the evaluation of the classification system, which doesn’t take into account the event in which athletes compete.

Introduction: Swimming is one of the most popular sports practiced by people with disabilities, and the number of participants during the subsequent Paralympic Games (PG) increases. One way to assess the level of sports in a given discipline is to analyze the sports results of the athletes competing at the highest level. Hence, the purpose of analysis was to compare the results obtained by the athletes with locomotor disability in swimming in the starting class (1-10) on the PG in the years 2000-2012. Material and methods: Were analyzed the results obtained by men with locomotor disability in swimming all styles, on all distances during the PG in 2000-2012. To assess the significance of differences between the results obtained by the swimmers in the analyzed period the Mann-Whitney U test were used. The level of significance was set at p <0.05. Results: We observed statistically significant differences in the level (increase) of obtained results in all classes and styles, on distances played during the next PG. Throughout the 8 and 12 years, almost all differences were statistically significant. This direction of change was most evident in case of athletes from higher start classes (6-10). Conclusions: The results indicate a steady increase in the sports results of men with locomotor disability in swimming. It could be caused by much interest in this form of activity among people with disabilities, especially those with less functional deficit. Attention should be paid to increasing the share of the athletes from low-start classes (1-5).

Introduction This study sought to analyze performance progression in track and field sprint events (100-400 m) at Paralympic Games (PG) held between 1992 and 2016 and to make comparisons with Olympic athletes. Material and methods Of 19 sport classes, five were selected in which the ratio of world records (WRs) set by Paralympic athletes to WRs set by Olympic athletes was the highest (T13 – visual impairments, T38 – coordination impairments, T46/47 – upper limb deficiencies, T42 and T44 – amputations and with lower limb deficiencies, T54 – wheelchair users). Percentage indices, PG/OG performance ratio as well as competition density were used to assess changes in performance. Linear regression was applied to predict performance at 2021 PG. Results In the period from 1992 to 2016, PG finalists improved their results by 5 to 22% in all the classes, while OG finalists improved their performance by 1 to 2%. PG/OG performance ratio depended on the class and sprint distance. The highest ratio was noted in the case of T44 (0.92 for 200 m) and T54 (0.93 for 400 m). Conclusions The prediction showed the highest values of the coefficient of determination (R2>70%) in T38 and T44 in 100 m and T38 in 200 m. The data obtained from the prediction may determine coaches’ activities in terms of assessing an athlete’s chances of qualifying for 2021 PG finals.

Introduction This study sought to identify and analyse the ranges, determinants and differences in physical activity levels of athletes with cancer. Material and methods The analysis included questionnaire responses provided by 169 out of 210 participants of the Onco-Olympics (80 out of 92 girls and 89 out of 118 boys). The mean age was 13.05 years for girls and 13.08 years for boys. The study group consisted of the following participants: 62 girls and 69 boys from Poland, 6 girls and 4 boys from Lithuania, 4 girls and 8 boys from Romania and 8 girls and 8 boys from Ukraine. The International Physical Activity Questionnaire (IPAQ) was used in the study. Results Girls demonstrated lower levels of vigorous (3.56 days per week, 88 minutes per day) and moderate (3.61 days per week, 96.5 minutes per day) physical activity than boys (3.91 days per week, 99.35 minutes per day, and 4.20 days per week, 103.7 minutes per day, respectively). Walking time per week was 16.18 hours for girls and 15.91 hours for boys, while sitting time per week was 5.17 hours for girls and 5.57 hours for boys. Athletes with neuroblastoma and bone cancer displayed the highest levels of vigorous and moderate physical activity, while its lower levels were found in athletes with leukemia, lymphoma and solid tumors. Physical activity levels differed depending on the type of cancer. Conclusions Physical activity of Polish athletes with cancer does not depend on their sex, age in the examined range, body mass, body height or the BMI but it depends on the type of cancer. Drawing on the example of the group of athletes under investigation, it is reasonable to assume that recommended physical activity levels (expressed in MET – minutes per week) ought to be different for persons with different types of oncological diseases.

Wstęp Celem było rozpoznanie i analiza zakresów, uwarunkowań i zróżnicowania aktywności fizycznej wśród sportowców z problemami onkologicznymi. Materiał i metody Analizie poddano odpowiedzi na pytania ankiety uzyskane od 169 osób na 210 uczestników igrzysk Onko-Olimpiady (80 dziewcząt i 89 na 118 chłopców). Średnia wieku dziewcząt wynosiła 13,05 lat, a chłopców 13,08 lat. Reprezentowali Polskę (62 dziewcząt i 69 chłopców), Litwę (6 dziewcząt i 4 chłopców), Rumunię (4 dziewczęta i 8 chłopców), Ukrainę (8 dziewcząt i 8 chłopców). Zastosowano międzynarodowy kwestionariusz aktywności fizycznej (IPAQ). Wyniki Dziewczęta wykazały mniejszą intensywną (3,56 dnia/tyg. po 88 min/dzień) i umiarkowaną (3,61 dnia/tyg. po 96,5 min/dzień) aktywność fizyczną niż chłopcy (intensywna – 3,91 dnia/tyg. po 99,35 min/dzień., umiarkowana – 4,20 dnia/tyg. po 103,7 min/dzień). Czas chodzenia w tygodniu (dziewczęta – 16,18 godz., chłopcy – 15,91 godz.) i siedzenia (dziewczęta – 5,17 godz., chłopcy – 5,57 godz.). Wśród sportowców największą intensywną i umiarkowaną aktywność fizyczną wykazały osoby z nerwiakiem zarodkowym i nowotworem kości, a mniejszą osoby z białaczką, chłoniakiem i guzami litymi. Istniało zróżnicowanie aktywności fizycznej ze względu na rodzaj choroby nowotworowej. Wnioski Aktywność fizyczna sportowców z problemami onkologicznymi w Polsce nie zależy od płci, wieku w badanym jego zakresie, masy, wysokości ciała a także wskaźnika BMI, a zależy od rodzaju choroby nowotworowej. Istnieją przesłanki na przykładzie badanej grupy sportowców do różnicowania zalecanej aktywności fizycznej wyrażonej w MET-min./tyg. dla osób z różnymi rodzajami chorób onkologicznych.

Purpose. The purpose of the study was to examine game efficiency of elite wheelchair rugby players in consideration of International Wheelchair Rugby Federation (IWRF) classification during the 2008 Paralympic Games played according to the old wheelchair rugby rules.Basic procedures. A group of 77 athletes representing 8 national teams participated in the study. Each team played 5 games for 32 min each. Athletes who played for more than 8 min in total at the 2008 Paralympics qualified for the study. The seven IWRF player point classes were collapsed into four groups. The game efficiency analysis was based on the IWRF Statistical Reports. The following six game efficiency parameters were analyzed: played time (T), sum of all points scored (PT), assist passes (AS), assist blocks (AB), turnovers (TO) and steals (ST).Main findings. The major finding of the study was that most differences in PT, AS, AB, TO and ST were found among all the examined groups (I-IV), except groups I and II. The played time (T) was not sensitive enough to identify significant differences among all the groups. This indicates that played time in the context of substitutions limited by classification point requirements does not reflect the differences between player classes.Conclusions. Generally, there was a tendency for highpoint class players to perform better. The study findings point to the importance of analysis of game efficiency of elite wheelchair rugby players with regard to their IWRF classification during tournaments played according to the new wheelchair rugby rules.

Introduction: Looking for solutions to improve physical fitness of persons with sensory impairments, both in the context of physiotherapy and the creation of adapted physical activity programs in the physical education and extracurricular activities, it seems important to determine the effect of sensory impairments at the level of coordination motor abilities (CMA). The aim of the study was to compare the coordination motor abilities of blind, deaf and able-bodied boys aged 14-17. Material and methods: The research was carried out on 37 boys: totally blind students (14) from the Education Centre for Blind Children in Laski, deaf students (18) from Deaf Institute in Warsaw and able-bodied peers (15) from School No.51 in Warsaw. The following tests evaluating selected CMA were used in the research: spatial orientation, dynamic balance, high frequency of movement, rhythmicising, kinesthetic differentmiation, connection of movement. Participants performed motor tests such as: walking into goal, turn on a bar of a gym bench, flat tapping, rhythmic drumming of upper and lower limbs, long jump at 50% capacity, transfering a gym stick, skiping with clapping under the knees, The Starosta Global Coordination Test. Measurements and evaluation of basic anthropometric parameters were done as well as Body Mass Index was calculated. Means of results of every tests were evaluated through nonparametric Krauskal-Wallis test. Statistical significance between the groups was determined using the U Mann-Whitney test. Results: Coordination motor abilities differentiated the groups of boys - blind, deaf and able-bodied. The lowest level of the CMA was obtained in a group of blind boys and there were only little differences between the deaf and able-bodied participants. For the blind boys the most difficult test was rotation on the bench gym, which may indirectly indicate low level of dynamic balance. Conclusions: The ability to rhythmic whole body and spatial orientation were the CMA that needed improvement in the group of deaf boys. There is no correlation between the results obtained in tests of CMA and body height, weight, BMI and age of individuals
