Opis:
Qualitative interviews with six female runners shed light on the gender gap in women’s participation in shorter versus longer road races. The interviews reveal that “mother guilt” and “time constraints” play a significant role in the development of a running identity among women. While the running community promotes a discourse centered around a “disembodied” runner — someone totally and unconstrainedly dedicated to running — the participants in this study experienced conflicts between their roles as mothers and their identity as runners. The conflicts led them to engage in challenging the dominant discourse by actively negotiating a mothering and running identity. The findings suggest that women are redefining the boundaries around running and subsequently — running subculture itself.

Background. Running tourism began to develop along with a growing popularity of running as a form of recreation. The aim of this study was to define the concept of running tourism and to find out the Polish runners’ motives for participation in this form of tourism. Material and methods. The research tool was a questionnaire developed by the authors. It was possible to fill it in during the Cracovia Marathon (04.22.2012) or online; 186 runners answered 20 questions in the detailed part of questionnaire. Results and conclusions. The runners chose the competition venue taking into account the length of the run and the distance from the place of residence. Other important factors were also: attractiveness of the competition, atmosphere and a desire to visit interesting places after participating in the competition. Awareness of running tourism among the runners in Poland is low. The majority of respondents (74%) stated they knew this term, but only 47% of respondents clearly admits participating in it. In Poland the form of running tourism – a guided running tour – does not exist, but it is a niche sector of travel services that has not been developed yet.

Opis:
The current investigation was conducted to determine whether sex differences in skeletal accelerations and shock attenuation were evident during running. Twelve male and twelve female recreational runners ran at 4.0 m.s-1. Axial accelerations were measured at 1,000 Hz using accelerometers mounted at the tibia and sacrum. Peak tibial and sacrum axial accelerations were obtained and utilized to calculate the extent of shock attenuation. The results showed that peak sacrum accelerations were significantly larger in female runners (5.16 ±0.64 g) compared to males (4.37 ±0.75 g). It was also shown that shock attenuation (31.90 ±19.85%) was significantly lower in female runners in relation to males (47.89 ±11.46%). The findings from the current investigation indicate that female runners experience greater skeletal accelerations which may place greater stress on the musculoskeletal structures required attenuate transients forces which can be detrimental to passive tissues.

Opis:
Physical differences associated with birth-date among athletes of the same selection year have been described as the Relative Age Effect (RAE). The aim of this study was to examine whether RAE still exists in soccer and running sport disciplines as well as to evaluate its progress among different gender, age, and sport context and if it has an effect on performance. Using official archives of the international sports’ associations (World Athletics-UEFA), birthdates and performance were collected for 7226 athletes (4033 males; 3198 females) who participated in soccer and running events. A chi-square test was used to assess differences between observed and expected birth date distributions. The study showed an over-representation of athletes born in the first quarter of the selection year for both soccer and running events. RAE is more obvious in younger age groups and in sports that require higher explosive speed, strength, power and anaerobic capacity such as soccer and short distance sprints. It was also found that RAE is associated with performance. In conclusion, athletes of younger age groups with greater biological age have a physical advantage in explosive sports (i.e. soccer and short distance running) that probably does not predict their future development.

Opis:
This study focuses on the development of a reliable prosthetic running blade primarily composed of carbon fiber. The reliable performance of novel prosthetic running blades has been evaluated by mechanical testing and finite element numerical modeling. Theexperimental analysis confirmed that these blades exhibit superior suitability for high-impact activities, demonstrating reliable load-bearing capacity and effective shock absorption properties. The tensile testing exhibited a linear elastic behavior of the composite material up to a strain of 0.075 mm/mm. Further, it was found that stress concentration areas and fracture points within the blade structure. Furthermore, numerical results revealed a maximum deflection of 29.60 mm that the blade can achieve. The kinetic energy loss during impact demonstrated an 8.5% decrease in blade kinetic energy, with the highest loss occurring at Vy = 30 m/s. Ultimately, this research aims to enhance the reliability, durability, and safety of prosthetic running blades, empowering athletes to reach new heights in sports.

The current study aimed to investigate the influence of energy boost, spring and conventional footwear on running economy and substrate usage. Ten male runners completed 5 min steady state runs in energy boost, spring and conventional footwear. Running economy and percent contribution of carbohydrate to total calorie expenditure were assessed. Participants also subjectively indicated which shoe condition they preferred for running. Differences between footwear were examined using repeated measures ANOVA. The results showed firstly that running economy was significantly improved in the energy return (33.36 ml.kg.min -1) compared to spring (34.83 ml.kg.min -1) and conventional footwear (34.65 ml.kg.min -1). In addition, percent carbohydrate was significantly lower in the energy return (74.51%) in comparison to the spring (78.56%) and conventional (78.52%) footwear. As running economy was improved and carbohydrate utilization reduced in the energy return footwear, this study indicates that they may be associated with improvements in running performance.

Nowadays Didymosphenia geminata is one of the most frequently studied diatoms in the world, due to its massive development in most continents. In Poland, up to the 1990’s only a small number of specimens were recorded, from streams in the Tatra Mountains and the Dunajec River. D. geminata was found in 2007–2008 in the middle and upper sections of the Wisłok River, while in 2009 and 2011 it was also found in the Wisłoka, Ropa, Bielcza and San. The cells belonged to one morphotype “geminata” and were characterized by high variability of size. It develops in mesotrophic, well-oxygenated, upper parts of flowing waters with rapid currents. It was most abundant below reservoirs on the San, Wisłok and Wisłoka.

The article presents results of an own research, which was carried out on a group of amateur runners from the Lodz province. The case of runners’ motivation was investigated. The survey was carried out by using an on-line questionnaire for 101 respondents, belonging to runner’s clubs and runner’s communities from the Lodz province. A key finding is, that the respondents were guided by health reasons when they had started running trainings. Running has become an easy way for them to improve their health, condition and stress reduction. Moreover, running also changed their non-sport sphere of daily life: their habits, self-esteem and openness for other people.
W artykule zostały przedstawione wyniki badania własnego, przeprowadzonego na próbie biegaczy-amatorów z województwa łódzkiego. W badaniu sprawdzano, jakimi motywacjami kierowali się biegacze, rozpoczynając przygodę z tym sportem oraz jak bieganie zmieniło ich życie i stan zdrowia. Badanie zostało wykonane z wykorzystaniem kwestionariusza ankiety on-line, objęło 101 respondentów, należących do klubów biegacza i społeczności biegaczy z województwa łódzkiego. Wyniki badań wykazały, iż ankietowani, gdy rozpoczynali treningi biegowe, kierowali się głównie przesłankami zdrowotnymi. Bieganie stało się łatwym sposobem na poprawę zdrowia, kondycji czy zredukowanie stresu. Rozpoczęcie przygody z bieganiem zmieniło także ich pozasportową sferę codziennego życia, zmieniły się ich nawyki i przyzwyczajenia; bieganie wniosło do ich życia wiele pozytywnych zmian.

We focus on finding patterns in the arrival times distributions as well as on studying the differences between the female and male runners’ arrival times distributions. The main statistical tools used are Analysis of Variance and Kolmogorov - Smirnov test for identifying underlying distributions and for comparing distributions of two samples. The obtained results indicate that the dynamics of groups of female runners is different than that of male runners. Also, a meaningful factor for the sha pe of the distribution is time limit set by the races organizers.

Opis:
Objectives. Post exercise proteinuria (PEP) is found in about 20–40% of sportsmen after intensive exercise. Urinary NGAL is a new marker of tubulointerstitial kidney damage. The relationship between PEP and uNGAL has not been defined yet. In presented study a resting uNGAL as a predictor of PEP was analyzed. The changes of albuminuria after exercise were monitored to estimate a frequency and range of PEP. Methods. 40 amateur healthy runners (mean age 36.65 ±10.61 years) participating in 10-km run took part in the study. Before and after the competition urine was collected. NGAL, albumin and creatinine were subsequently measured in urine. uNGAL to creatinine ratio (NCR) and albumin to creatinine ratio (ACR) were calculated. Results. 28 participants (mean age 37.9 ±11.46, 19 M, 9 F) with uNGAL below 15 ng/ml before competition were analyzed. The increase of ACR was observed in every case. Mean post-exercise ACR was 104.55 ±123.1 mg/g and was significantly higher than pre-exercise ACR 6.33 ±5.86 mg/g (p < 0.0005). The positive correlation was found between resting NCR and post-exercise ACR (r = 0.60, p < 0.05). Conclusions. Resting uNGAL positively correlated with PEP. The possible explanation of these findings is that persons with PEP had some early, occult tubulointersitial kidney damage. It is speculated that those runners have higher risk of chronic kidney disease.

The article discusses a preliminary concept of a method enabling the identification of chosen rail running surface defects, such as squats, spalling, and running surface defects, by analysing the parameters of vibration signals. It features a description of the methodology of the conducted tests, the scope thereof, and the selection of the measurement points with specific defect types. The article covers selected results of vibration tests, the results of analyses of recorded signals for defective track sections and those for control track sections. The presented measurement results have been obtained for the technical–operating conditions occurring on railway line no. 213 Reda – Hel and line no. 131 Chorzów Batory – Tczew. The preliminary test results and conclusions included in the article show that it is reasonable to pursue further research into the phenomena involving the utilisation of vibroacoustics in rail performance diagnostics.

Opis:
This paper presents a modified Independent Component Analysis (ICA)-based Fault Detection Method (FDM). The proposed FDM constructs a set of matrices, revealingthe trend of the variable samples and execute ICA algorithm for each set of matrices in contrast to the FDM based on dynamic ICA (DICA) which constructs the high dimensional augmented matrix. This paper shows that the proposed FDM decreases the matrix dimensions and as a result compensates for some disadvantages of using the high dimensional matrix discussed in previous articles. Furthermore, other advantages of the proposed FDM are the decreases in the running time, computational cost of the algorithm and the orthogonalization estimation errors. Moreover, the proposed method improves the detectability for a class of faults compared to DICA-based FDM. This class of fault occurs when two or more consecutive samples of fault source signal have opposite signs and cancel out each other. Simulation results are provided to show the effectiveness of the proposed methodology.

Opis:
Running is one of the most popular methods of spending time in active form in the world. The vast majority of managers who organise runs are former or actual runners. It is interesting to note that more men are leaders of teams which organise running events, while women as leaders are very rare. The main purpose of the research was to find the influence of sex of leader on the style of leadership, decision process and atmosphere in team. The author of this article conducted quality research using individual deep interview method. Data were collected from 23 individual deep interviews with managers of big running events organised in Poland, and 14 with the members of their teams. Currently, effective leaders should have competences different than what were prevalent 20–30 years ago. More important is, for example, emotional intelligence, empathy and interpersonal skills. Organisations operating in the amateur sport market have to build networking with many partners from the public and business sector, so leaders should concentrate on cooperating with stakeholders representing different expectations. Competences that women possess over men are required. Unlike other industries, in the running market there are very few women as leaders. Several reasons abound for this, some of which include economic and sociological grounds.

Triathlon is dev eloping very quickly nowadays. In our paper we are interested in cross triathlon. The road bike is replaced by the mtb mountain bike and the run is also done in the mountain. Triathlon is the endurance kind of sport where the AeT’s (aerobical threshold) a nd AnT’s (anaerobical threshold) level is the basic indicator of a sports performance. The curve of the both thresholds changes under the influence of a lot of factors during the year. We studied the influence of the running preparation on the aerobic and anaerobic threshold at the cross triathlon specialist during one year. We monitored the level, especially the changes in the sports performance during the ATC (annual training cycle). We valued the training proccess, the quantization of the training load and its influence on the triathlet’s performance with the intraindividual analysis.We gained the necessary data from the training diary and with help of the tests realized in the laboratory conditions .We detected the speed at the aerobic and anaerobic thr eshold by the running belt. Then we corelated them with the training parameters and we found out the addaction. We followed their actual influence on the performace and the influence of the training paramaters in the time intervals.

Thirty-three male students (age 11.27±0.64 year, weight 40.58±9.03 kg, height 151.45±6.34 cm) were recruited from preliminary school and randomly were assigned into rope-jump training (n=12), running training (n=11) and control (n=10) groups. Due to the grouping, each for 8 weeks did the rope jumping or running. Before and after the 8-week training period, factors of health-related fitness, including flexibility, muscular endurance, aerobic power and fat Percentage of the subjects were measured. The results indicated a significant positive effect of rope-jumping training on aerobic power, muscular endurance and body composition and meaningful improvement of aerobic power and body composition by running training (p≤0.05). Due to increasing urbanization and lack of space in homes and schools, rope-jump training can be a good alternative rather than running for physical fitness promotion.

Opis:
The aim of this study is to examine and evaluate the effects of long-term stress on muscle and heart biomarkers after completing a 100 km ultramarathon. Material and Methods: Venous blood samples of nine runners (average age 38.8±10.2 years), who successfully finished a 100 km ultramarathon at an elevation of 3130 m, were examined before the start, at the finish line immediately after the run, one day after the run and then after 5 and 10 days. Clinical, laboratory, and somatometric data were obtained from all measurements, and biomarkers: aspartate aminotransferase (AST), cortisol (COR), troponin T (cTnT), creatine kinase (CK) and C-reactive protein (CRP). Also, their training experience and ultramarathon experience was monitored. Discovered values were further analyzed with the use of t-test a ω2 (ω2≥0.1), and Spearman's rank correlation coefficient (r) at the significance level of p<0.05. Results: The average finish time of the runners was 13:55:40 (min: 12:12:35, max: 16:52:02). After finishing the ultramarathon, runners showed an average weight loss of 2.4 kg (p<0.05). The results show that hematological changes were caused by physiological stress and long-term physical load. The values of all monitored biomarkers showed a significant exceeding of the normal values immediately after the race in 8 competitors out of 9. The values of cTnT showed an increase of more than 50 % (pre -race: 8.2±2.3, post-race: 34.22±25.9 ng/l, max=98 ng/l). After 24 hours, however, this condition had returned to the normal values for all participants. The results show that the AST hepatic enzymes significantly correlated with the training experience (r=-0.41, p=0.043), the total number of kilometers run per year (r=-0.45, p=0.04) and the achieved finish time (r=0.67, p=0.001). At the same time, athletes who had the best finish time achieved lower CRP values (r=0.74, p=0.023) and cTnT values (r=0.49, p=0.040). The study found that the competitors who had the longest experience with ultramaraton had the lowest cTnT (r=0.44, p=0.050). Conclusion: Long-term physical stress is associated with metabolic and cardiovascular changes. Blood abnormalities found in our study suggest that due to long-lasting extreme stress, heart exhaustion may occur. However, these changes did not last long and after a few days they returned to the normal values for all runners.

Opis:
W XXI w. na świecie zaczęto z zamiłowaniem uprawiać biegi rekreacyjne. Od 2013 r. jogging stał się najbardziej popularną aktywnością fizyczną wśród Polaków. Głównym celem artykułu jest ukazanie, że bieganie rekreacyjne, które jest nie tylko aktywnością ruchową służącą utrzymaniu właściwej kondycji fizycznej, ale także „sportem dla wszystkich”, zaczyna przybierać rangę specyficznego produktu turystyczno-sportowego – imprezy biegowej. W pracy do analizy wybrano toruńskie zawody biegowe i wydarzenia im towarzyszące, a także wykorzystano dane statystyczne dotyczące organizacji imprez biegowych w Polsce.
In the twenty-first century recreational running has been taken up and practised by people virtually on a global scale. Since 2013, jogging has become the most popular physical activity among Poles. The main aim of this article is to demonstrate that recreational running is not only a physical activity performed in order to maintain proper physical condition, but also as a „sport for everyone”, it begins to take the status of a specific tourist and sport product – a running event. In this article, running competitions in Torun and supporting events have been selected for the analysis, as well as statistical data has been used concerning the organization of running events in Poland.

Opis:
Authors in their contribution deal with the issue of reactive and running agility in sport. Upon constructing the methods of research we assumed that players ́ performances in running agility (Illinois test) should increase with the age of soccer players. W e expected that we shall not prove this tendency in the level of reaction agility (FAC) with regard to the fact that performance in reaction agility is limited, besides motor, also by other prerequisites such as perception, state of receptors, sensoric and autonomous functions, spinal and supraspinal levels of motor system. We also expected that there will be no proved relationship between these tests ́ results in any age category. The level of performance in running and reactive agility increases with age; t he increase is smooth in running agility and cascaded in reactive agility starting with the 14 yrs. category. We also noted a downward tendency in the correlation between running and reactive agility with increasing age. This decline is most evident from t he 14 th year of age. The relationship between running and reaction agility was not observed in the study group from the age of 13. Coaches are recommended to switch over to the specific development of agility using the way of weakening anticipation ability of the player and to replace exercises with closed -loop skills by the ones of open -loop skills.

Opis:
The article presents the results of a questionnaire survey aimed at determining social preferences in relation to running as a form of active leisure time in forests. These preferences were established on the basis of surveys conducted via the Internet by means of social media services. The survey was carried out in 2016 and covered 346 people living in Poland, interested in running and jogging. It involved people over 18 years of age. As a research tool, an Internet questionnaire was used, which included questions concerning the attractiveness of the forest for practicing running, the frequency of running events in the forest, and factors motivating to take part in the running event. Statistical analysis was performed considering the influence of personal characteristics (gender, age, place of residence) and experience in running on the preferences of respondents with the use of the chi-square test. Men dominated among the respondents. The majority of respondents were people aged 35–44 living in towns. Over half of the respondents declared that they practiced athletic or recreational running for more than 4 years. The results show that the Polish forests are an attractive place for running. The preferences varied significantly, mainly in relation to gender, age, and experience in running. Age differentiated the views of respondents on the attractiveness of the forest as a place for running. Participating in forest running events was determined by gender, place of residence, and experience in running. Participants of such events are more frequently men, residing in towns. It was observed that the frequency of participation in running events increases with experience. The attractiveness of the running event was associated mainly with its general atmosphere and the characteristics of the running trail. However, the views were diversified according to gender, age, residence, and experience in running.

Opis:
The current investigation aimed to examine the effects of different orthotic conditions on the biomechanical mechanisms linked to the aetiology of chronic pathologies using musculoskeletal simulation. Methods: 16 male and 20 females ran over an embedded force plate at 4.0 m/s, in five different conditions (medial, lateral, no-orthoses, semi-custom and off the shelf). Kinematics of the lower extremities were collected using an eight-camera motion capture system and lower extremity joint loading also explored using a musculoskeletal simulation approach. Differences between orthoses conditions were examined using 2 2 mixed ANOVA. Results: External instantaneous load rate was significantly reduced in the off the shelf orthoses (male = 1290.60 and female = 1567.10 N/kg/s), compared to the medial (male = 1480.45 and female = 1767.05 N/kg/s) and semi-custom (male = 1552.99 and female = 1704.37 N/kg/s) conditions. In addition, peak patellofemoral stress was significantly lower in the off the shelf orthoses (male = 68.55 and female = 94.91 KPa/kg) compared to the lateral condition (male = 70.49 and female = 103.22 KPa/kg). Finally, peak eversion angles were significantly attenuated in the medial orthoses (male = –6.61 and female = –7.72 deg) compared to the lateral (male = –9.61 and female = –10.32 deg), no-orthoses (male = –8.22 and female = –10.10 deg), semi-custom (male = –8.25 and female = –9.49 deg) and off the shelf (male = –7.54 and female = –8.85 deg) conditions. Conclusions: The current investigation shows that different orthotic devices/ configurations may provide distinct benefits in terms of their effectiveness in attenuating the biomechanical parameters linked to the aetiology of chronic running injuries.

Opis:
In many countries we are observing now an increase of fashion for running and in connection with the participation of athletes in various running events – marathons, halfmarathons, ultramarathons. Running events become recently an important stimulus to the development of sports tourism, now one of the fastest growing industries of leisure time. The aim of this article is to show who participates in running events in Poznań (the case study of Poznań Halfmarathon). The work on the basis of empirical studies conducted using diagnostic survey interview technique standardized defined socio-demographic profile of both athletes, who live in the city where the event is held and defined the profile of the runner – sports tourist.
W wielu krajach obserwujemy obecnie wzrost mody na bieganie i w związku z nim udział sportowców w rozmaitych imprezach biegowych – maratonach, półmaratonach, ultramaratonach. Imprezy biegowe stają się w ostatnim czasie istotnym stymulatorem rozwoju turystyki sportowej, dziś jednej z najdynamiczniej rozwijających się gałęzi przemysłu czasu wolnego. Celem artykułu jest przedstawienie, kto jest uczestnikiem imprez biegowych w Poznaniu – na przykładzie Półmaratonu Poznańskiego. W pracy na podstawie badań empirycznych przeprowadzonych metodą sondażu diagnostycznego, techniką wywiadu standaryzowanego, określono profil społeczno-demograficzny sportowców, mieszkających w mieście, w którym odbywa się impreza, określono też profil biegacza – turysty sportowego.
