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:
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.

In this paper, we analyze data sets, collected from the public web sites, containing the finishers arrival times in five different half marathons. 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.

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.

The purpose of this study was to compare of two aerobic training methods on health-related physical fitness in 10 to 12 years old boys. 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 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.

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.

The aim of the research is to analyze the quality of life improvement (Kaizen) in the running aspect in Poland. Until now, issues related to the running analysis of the quality life in terms were not the subject of broader, comprehensive scientific considerations. The research was taken in 2019 year and covered a group of 396 runners. The respondents are women posing 67,9% and men posing 32,1% residing in different areas of Poland. The research was based on a questionnaire (CAWI - Computer Assisted Web Interview). Although for most respondents the result is not the most important, they try to improve their running attitude and time. Runners use different ways to be motivated to work on themselves. An example of motivators can be a medal, obtained at the finish line or sharing success with participation in competition on social networks (Facebook).

Opis:
Trendy związane z dbałością o środowisko, ochroną przyrody i propagowaniem ekologicznych rozwiązań w życiu codziennym coraz częściej widoczne są również w turystyce i rekreacji. Jednym z popularniejszych wśród biegaczy jest plogging, czyli połączenie biegania i zbierania śmieci. Na świecie oraz w Polsce odbywa się coraz więcej ploggingowych imprez, a w mediach społecznościowych tworzy się coraz więcej lokalnych grup ploggingowych. Wśród 158 studentów Turystyki i rekreacji Uniwersytetu Pedagogicznego w Krakowie przeprowadzono anonimową ankietę, której celem było poznanie opinii na temat stanu wiedzy studentów dotyczącej ploggingu, jego popularności i przydatności w Polsce, a także ocena niektórych zachowań badanych osób związanych z dbałością o otoczenie. Niewielka grupa badanych słyszała wcześniej o idei ploggingu. Większość studentów uważa plogging za bardzo dobrą inicjatywę, lecz niewielka tylko część przyłączyłaby się do tego typu aktywności. Znaczna część studentów nie zbiera śmieci pozostawionych przez innych, a za zły stan czystości terenów rekreacyjnych winią m.in. zbyt małą dostępność koszy na śmieci oraz niski stan świadomości społecznej.
Trends related to care for the environment, nature protection and promotion of ecological solutions in everyday life are also increasingly visible in tourism and recreation. One of the most popular among runners is plogging, which is a combination of running and collecting rubbish. There are more and more plogging events in the world and in Poland, and more and more local plogging groups are created in social media. An anonymous questionnaire was conducted among 158 students of Tourism and Recreation, the purpose of which was to find out the opinion on the state of knowledge of these students about plogging, popularity and usefulness in Poland, as well as to evaluate some of the behaviors of respondents related to caring for the environment. A small group of respondents had heard about the idea of plogging before. Most students find plogging a very good initiative, but a small minority of them would join to this type of activity. A significant number of them do not collect rubbish left by others, and blame the poor cleanliness of recreational areas, among others, on insufficient availability of litter bins and low level of public awareness.

Wstęp. Bieganie w krajach rozwiniętych jest bardzo powszechną i łatwo dostępną formą aktywności fizycznej, jego głównym celem stała się rekreacja i sport. Celem pracy była ocena najczęściej występujących kontuzji/urazów u osób regularnie biegających w biegach długodystansowych w formie amatorskiej. Materiał i metody. W badaniu wzięło udział 140 osób, 79 kobiet oraz 61 mężczyzn w wieku od 18 do 61 lat, głównie mieszkańcy Warszawy. Średnia wieku to 35,59 (SD 9,24). Dane zostały zebrane za pomocą ankiety, metodą sondażową, a opisane zostały w sposób jakościowy bez użycia analiz statystycznych. Wyniki i Wnioski. 91 badanych ze 140 doznało różnych kontuzji podczas biegania. Do najczęstszych urazów u biegaczy doszło w okolicy stopy i stawie skokowym, były to skręcenia (30%), naderwania (16%) i przeciążenia (16%). Większość osób biegających stosuje odnowę biologiczną w tym prawie połowa automasaż. Regularne bieganie stanowi dobrą formę dbania o zdrowie, prawie wszyscy badani polecili by ją innym osobom.
Background. Running in developed countries is a very common and easily accessible form of physical activity, its main goals include recreation and sport. The aim of the study was to assess the most common injuries in people regularly involved in amateur long-distance runs. Material and methods. 140 people, 79 women and 61 men aged 18-61, mainly residents of Warsaw, participated in the study. The mean age is 35.59 (SD 9.24). The data was collected by means of a questionnaire, survey method, and described in a qualitative manner without the use of statistical analyzes. Results and Conclusions. 91 of the 140 subjects suffered various injuries while running. The most common injuries in runners were to the foot and ankle area and included sprains (30%), tears (16%) and overloads (16%). Most of the runners undergo biological regeneration and almost half of them use self-massage. Regular jogging is a good form of taking care of health and almost all respondents would recommend it to other people.

Opis:
Ultra-marathon running has enjoyed increasing popularity, with the number of master ultra-marathon runners growing annually. This study presents a case of a 51-year-old highly experienced long-distance runner (body mass: 65.1 kg, body height: 168 cm), who took part in a 48-h ultra-marathon race held in 2010, but dropped out of the competition due to acute cardiac problems manifested after 16 h of running and having completed a distance of 129 km. Two weeks following the race, intense cardiac examination was performed to explain the drop-out due to chest pain. A 12‑lead electrocardiogram, a 2D transthoracic echocardiography in 3 apical projections of the left ventricle, a computed tomography of the chest, an invasive coronary angiography and a maximal oxygen uptake (VO2max) test were performed. The 12-lead ECG revealed a negative T wave in III and aVF without morphological abnormalities. The echocardiographic examinations presented a normal size and function of the heart chambers, and a normal valvar structure and function (only trivial mitral and tricuspid regurgitation was observed). The invasive coronary arteriography – due to an increased calcium score in the CT scan – showed only a non-significant systolic dynamic narrowing in the eighth segment of the left anterior descending artery due to a muscle bridge. The physical performance characteristics of the athlete and a follow-up history of his athletic activity showed that the cardiac problems he had experienced during the ultra-marathon race did not prevent him from being active in sport.

Opis:
Purpose: The aim of this study was to determine how minimalist running shoes (MRS), conventional running shoes (CRS) and the dominance of lower limbs influence the running gait. Methods: Trained recreational runners (N = 13) who have been engaged in regulary running for more than one year were participants in this study. They were experienced with using MRS and CRS for more than half year and they used both types of shoes. An in-shoe pressure measuring system (Pedar-X®, Novel, Munich, Germany) was used to monitor plantar pressure and vertical force and the temporal parameters when running in MRS and CRS during the stance phase, the swing phase and over one stride. Results: Running in CRS significantly prolonged stance, swing and stride phases by 2–11% compared to MRS. In contrast, when running in MRS significantly larger values of maximum pressure (9–14%) and maximum vertical force (3–7%) than in CRS were found. Conclusions: For this reason, running in MRS could be recommended to recreational runners only with care. The effect of limb dominance on temporal characteristics was detected when running in CRS. Significantly longer stance phase for dominant limb is associated with a shorter swing. The kinematics variables were significantly higher for dominant limb than for non-dominat limb when running in MRS and CRS (by 12–23%).
