Didelio meistrškumo maratono bėgikų treniruotės ypatumai / Features of high mastership marathon runners training

Macevičius, Artūras 01 August 2013 (has links)
Kiekviena sporto šaka turi savo specifinius komponentus, kurie atskleidžia tikrąsias vienos ar kitos sporto šakos ar rungties galimybes (Karoblis, 2005). Nustatyta, kad didelio meistriškumo maratono bėgikų ugdymas priklauso nuo daugelio veiksnių, iš kurių svarbiausias yra treniruotės vyksmo kryptingumas, jo valdymas, atsižvelgiant į sportininko organizmo adaptacijos prie treniruočių ir varžybų krūvių individualus ypatumas (Skernevičius, 1997; Milašius, 1997; Астранд, 1994). Didelio meistriškumo bėgikai į metus ruošiasi dviems maratonams. Todėl treniruočių proceso valdymas yra vienas iš sudėtingesnių. Tyrimo objektas: maratono bėgikų treniruotės ypatumai. Tyrimo tikslas: išanalizuoti Lietuvos didelio meistriškumo maratono bėgikų treniruotės ypatumus. Tiriamieji: daugiakartinis Lietuvos ilgųjų nuotolių bėgimo čempionas Marius Diliūnas, pasiekęs 15-ą maratono bėgimo rezultatą šalyje ir daugiakartinis ilgų distancijų bėgimo rungčių Lietuvos prizininkas Kęstutis Jankūnas, pasiekęs 20-ą maratono bėgimo rezultatą šalyje. Analizuojant sportininkų treniruočių planus (sportininko dienynus), trenerio pildomą krūvio apskaitos žurnalą buvo kreipiamas dėmesys į treniruočių krūvių intensyvumą, sportininkų pulso rodmenis. Mokslinių šaltinių studija parodė, kad ugdant ištvermę, svarbu pasirinkti tinkamą pratimų intensyvumą pagal planuojamą maratono rezultatą. / Each sports branch has its own specific components revealing true capacities of different sports branches or events (Karoblis, 2005). It has been found out that development of high performance marathon runners depends on many factors including the most important ones: purpose of the training proceeding, its control with regard to individual features of sportsman’s organism’s adaptation to training and race loads (Skernevičius, 1997; Milašius, 1997; Астранд, 1994). High performance runners are prepared for two marathons in a year. Therefore, control of the training process is one of the most complex. The research object: features of marathon runners’ training. The research aim: to analyse features of training of Lithuanian high mastership marathon runners. The surveyed: a many-times champion of long distance run in Lithuania, Marius Diliūnas, who has achieved the 15th result in marathon run in the country, and a prize winner of long distance run in Lithuania, Kęstutis Jankūnas, who has achieved the 20th result in marathon run in the country. When analysing plans of sportsmen training (sportsmen’s journals), the journal of trainer’s additional load accounting, attention was paid to intensity of training loads, indices of sportsmen’s pulse. The survey of scientific sources suggests that, when developing endurance, it is important to choose a proper intensity of exercises according to the planned result in marathon.

A comparative study of acute responses to running in elite black and white marathon athletes

Bosch, Andrew Norman January 1985 (has links)
Experienced male marathon runners, 9 black and 10 white, with marathon times of 2 hours 45 minutes or faster, acted as subjects for the study, the purpose of which was to determine whether black runners are better suited to marathon running than whites. Body composition was determined by anthropometry. Maximal oxygen uptake (VO₂ max) and other physiological variables were measured during a continuous, speed-incremented treadmill protocol using a computer-aided data acquisition system. Subjects also ran a simulated marathon at 92.5% of the running speed at which the ventilatory threshold (VT) occurred. Physiological, gait and RPE variables were measured at 10 minute intervals during the marathon. Major findings are detailed below:- The VO₂, max averaged 60.4 ∓ 6.5 and 63.2 ∓ 2.9 mI. kg⁻¹.min⁻¹ in the black and white runners respectively and was highly correlated with best marathon race time (r = 0.86 and 0.85 respectively) and VT (r = 0.84 and 0.60 respectively) (p < 0.05). No significant differences existed between the groups in submaximal oxygen uptake (VO₂,) or % VO₂ max utilised at 16 km.hr⁻¹, but the estimated % VO₂ max utilised during a marathon race was higher in the black (89.0 ∓ 5.5%) than the white runners (81. 5 ∓ 3.1%) {p .( 0.05). The % VO₂ max utilised at 16 km.hr⁻¹ (84.8 ∓ 9.1 and 78.6 ∓ 5.8% in the black and white runners respectively) was significantly correlated with the % VO₂, max utilised while racing in the white (81.5 ∓ 3.1%) (r = 0.70) (p < 0.05), but not the black runners (89.0 ∓ 5.5%). The VT occurred at 82.7 ∓ 7.7 and 75.6 :∓ 6.2% VO₂; max in the black and white groups respectively (p < 0.05). Post-marathon blood lactic acid levels were lower in the black (1.30 ∓ 0.26 mmo1.l⁻¹) than the white runners (1.59 ∓ 0.20 mmol.l⁻¹). The respiratory exchange ratio (R) was higher in the blacks than whites when running at 16 km.hr ⁻¹ (1.03 ∓ 0.07 and 0.98 ∓ 0.03 respectively) and during the marathon (p < 0.05). There was no significant difference in pulmonary minute ventilation (Vı) between the groups, but breathing frequency (f) was higher in the black (59 ∓ 12 breaths.min⁻¹) than the white runners (45 ∓ 8 breaths. min⁻¹ ) and tidal volume (V⊤) lower in the black ( 1.33 ∓ 0.16 l.breath⁻¹) than the white runners (1.75 ∓ 0.36 I.breath⁻¹) during submaximal running at 16 km. hr⁻¹ (p < 0.05). The same trend was observed during the marathon run. During the time-course of the marathon f increased and V⊤ decreased In both groups (p < 0.05). Stroke volume decreased and heart rate increased In both groups during the time-course of the marathon (p< 0.05). Cardiac output was therefore maintained. Thermal responses were similar in the two groups. A significant increase in rectal temperature coincided with a decrease in skin temperature and may have been related to an increase in f (r = 0.86 and 0.67 in the blacks and whites respectively), H/R (r = 0.70 and 0.67 respectively) and "local" (leg) RPE (r = 0.84 and 0.82 respectively). It was concluded that black runners were able to run marathon races at a higher % VO₂ more than whites due to the blacks having lower blood lactic acid levels when running at a similar % VO₂ max. Given similar maximal oxygen uptakes, this would enable blacks to run faster. Cardiopulmonary adjustments occur during the time-course of a marathon which maintains Q and Vı

Husby Marathon : <em>En studie av projektets betydelse för ungdomars sociala kapital ochsjälvidentitet</em>

Manaci, Sarineh, Poedtke, Vanja January 2009 (has links)
<p>The purpose of this study was to investigate youth’s experiences of what meaning the nonprofit youth project Husby Marathon had on their social capital and self-identity. In order to answer the purpose a qualitative methodology was used based on interviews with four of the participant youths. Two teories were used, Social capital by Robert D. Putnam and Selfidentity by Anthony Giddens. The result indicates that the project has had a significant impact on the creation of social capital, in particular bridging social capital which was strengthened by an extended social network that the participants were offered. A strong social bond developed within the project, which also helped to strengthen the bonding social capital. Civic awareness was raised among the participants which also established a trust towards strangers and the society. Different parts of the project has given the participants opportunity to reflect on their identity. The participants have gained self-efficacy by learning goaloriented methods which has generated new and evolved self-identity. This has shown to increased the youths ability to make decisions and lifestyle choices. The results generated a development of three new concepts that are important for the integration of youth in suburbs. The two first concepts are "social self-identity" and "commitment-building social capital" and these two led to the final concept "social self-resource capital".</p>

Vilka marknadsföringsstrategier är lämpliga för evenemang inom maratonlopp för att locka besökare? : En jämförande studie där en litteraturstudie framställs och jämförs med hur Stockholm Marathons aktörer arbetar med marknadsföringsstrategier för att locka besökare

Jerkovic, Elvira, Isaksson, Petronella January 2023 (has links)
Marknadsföringsstrategier är ett redskap som kan användas i flera syften av flera olika aktörer, bland annat företag, föreningar och andra verksamheter. I denna studie undersöks evenemanget Stockholm Marathon och vilka marknadsföringsstrategier deras aktörer använder i syfte att attrahera besökare till deras event för att därefter kunna sammanställa vilka marknadsföringsstrategier som är lämpliga för evenemang inom maratonlopp. Studiens syfte är att öka förståelsen för hur Stockholm Marathon arbetar med dessa strategier för att locka besökare men även att skapa förståelse för vilka marknadsföringsstrategier som är lämpliga för evenemang inom maratonlopp. Genom en intervju med Marathongruppen, som ansvarar för eventet Stockholm Marathon, en litteraturstudie, samt en netnografisk analys, har undersökningen kunnat sammanställa en slutsats som besvarar studiens frågeställning. Datainsamlingen visar att flera marknadsföringsstrategier är lämpliga men att olika strategier passar olika bra beroende på exempelvis målgrupp. Eftersomolika målgrupper bland annat föredrar olika marknadsföringskanaler så lyckas inte alla kanaler nå ut till det specifika evenemangets målgrupp. Dessutom har det visat sig att olika målgrupper har olika preferenser gällande evenemanget, exempelvis visade sig helhetsupplevelser och destinationen som evenemanget träder plats på vara av vikt för Stockholm Marathons besökare likväl som besökare vid andra maratonlopp. Digitaliserad marknadsföring i form av exempelvis egenskapat innehåll i sociala medier visade sig även vara en strategi som når ut till flera målgrupper beroende på kanalval. Den digitala marknadsföringen har även uppenbarat sig som en källa till engagemang, involvering och djupare relationer mellan besökare och aktörer vilket visade sig påverka beteenden i form av ökat intresse att besöka evenemanget. / Marketing strategies is a tool that can be used for several purposes by several different actors, including companies, associations and other businesses. In this study, the event Stockholm Marathon is examined as well as which marketing strategies their actors use to attract visitors to their event in order to then compile which marketing strategies are suitable for marathon events. The aim of this study is to increase the understanding of how Stockholm Marathon works with these strategies to attract visitors but also to create an understanding of which marketing strategies that are suitable for events within marathons. Through an interview with Marathongruppen, who are responsible for the event Stockholm Marathon, a literature study, and a netnographic analysis, the study has been able to compile a conclusion that answers the study's question. The collection of data shows that several marketing strategies are suitable, but that different strategies will fit differently depending on, for example, the target group. Because different target groups, among other things, prefer different marketing channels, not all channels succeed in reaching the specific event's target group. In addition to this, it has been shown that different target groups have different preferences regarding the event, for example the overall experience and the destination where the event takes place proved to be important for the visitors of Stockholm Marathon as well as visitors at other marathons. Digitized marketing in the form of, for example, self-created content in social media also proved to be a strategy that manages to reach several target groups depending on the choice of channel. Digital marketing has also revealed itself to be a source of commitment, involvement and deeper relationships between visitors and actors, which proved to influence behavior in the form of increased interest in visiting the event.

The effect of a 50-km ultramarathon on vitamin B-6 metabolism and plasma and urinary urea nitrogen

Grediagin, Ann 10 August 2000 (has links)
The purpose of this study was to examine the effect of extreme exercise on vitamin B-6 metabolism and urea nitrogen. Nine men and five women completed two 5-day trials; Trial 1 (T1) included a 50-km ultramarathon on day 4 and during Trial 2 (T2) subjects were "inactive" on day 4. During both trials, subjects consumed a diet providing men 2.0 and women 1.5 mg of vitamin B-6. With the exception of the ultramarathon, T1 activity was replicated during T2. Twenty four-hour urine collections were completed and blood was drawn pre-race (pre), mid-race (mid), post-race (post) and 60 minutes post race (P-60). On the inactive, day blood was drawn at the same intervals. Plasma was analyzed for pyridoxal 5'-phosphate (PLP), pyridoxal, 4-pyridoxic acid (4-PA), urea nitrogen (PUN), creatinine, albumin, glucose, and lactate concentration and alkaline phosphatase activity. Urine was analyzed for 4PA, creatinine, and total urinary nitrogen (TUN). During T1, compared to pre, plasma PLP concentration increased 17% at mid, decreased 5% by post, and 19% by P-60. During T2, plasma PLP concentration decreased 13% pre to P-60. During T1, plasma 4-PA concentration increased 135% and the percent dietary vitamin B-6 that was excreted as urinary 4-PA the day of the ultramarathon was higher than that excreted the day before and the day after. During T1, from pre to post mean PUN concentration increased 36.9%, and the average rate ofincrease from pre to mid, mid to post, and post to P60 was 0.5, 1.75, and 2 mg/dL/hour, respectively. During T1 on days 3, 4, and 5,88%, 100%, and 95% of nitrogen intake was excreted in the urine compared to 86%, 83%, and 84% for the same days during T2. The day of the ultramarathon, 24-hour TUN excretion was 2 g higher than the previous day. Extreme exercise of greater than six hours initially increases the plasma concentration of PLP but ultimately results in a significant decrease in plasma PLP, an increase in plasma 4-PA, and an increase in percent of dietary vitamin B-6 (as 4-PA) excreted in the urine. Additionally, the rate of change in PUN inoeases as duration increases. / Graduation date: 2001

Crisis in Sports: An Assessment of the Ongoing Vulnerability to Terrorism in the Modern Age through an Analysis of the 1972 Munich Olympics and the 2013 Boston Marathon

Boyle, Catherine Hennelly January 2014 (has links)
Thesis advisor: Donald Fishman / This thesis examines and compares the terrorist attacks at the 1972 Munich Olympics and the 2013 Boston Marathon in order to assess the ongoing vulnerability to terrorism at international sporting events, in specific, and the global environment, in general. In each of these instances, terrorists took advantage of the vulnerability of large international sporting events and launched attacks that had both political and social implications. Although each attack had separate motives, results, and repercussions, both incidents served as crises in a rising media age and impacted public policy. This paper compares and contrasts the 1972 Munich Olympics and the 2013 Boston Marathon through theoretical analyses of Downs’ Issue Attention Cycle and Birkland’s Focusing Events Theory, as well as through a comparison of the crises’ dominant features. Over the course of the 40 years separating the events, security and emergency response methods have improved, as have technology, media, and information flow. Even with these modern techniques, however, today’s generation, as with its predecessors, still lives in an age of vulnerability to terrorism. The conclusion combines the analysis of the issue-attention cycle and the potential public policy changes in accordance with the 1972 Munich Olympics attack and the 2013 Boston Marathon bombings to argue that there is no fool-proof prevention method to the issue of vulnerability to terrorism and that the global community will to continue to be vulnerable in the future. / Thesis (BA) — Boston College, 2014. / Submitted to: Boston College.

Lessons to be learned from three mass casualty events - 2013 Boston Marathon Bombing, 2009 Aurora Movie Theatre Shooting, and 2005 Hurricane Katrina

Lee, Vivian 08 April 2016 (has links)
Disaster preparedness is absolutely necessary as the number of both man-made and natural disasters increases worldwide. Not confined to any regions or people, disasters can result in mass casualties. The United States is not spared from these incidents. Ever since the 9/11 terrorist attacks, the United States has tried to establish more effective and efficient emergency management systems at all levels in order to respond to any type of disaster. Due to the effort, much improvement in disaster preparedness was observed when mass casualty events happened within the last 10 years. Although there are many independent studies for each mass casualty event, there are very few studies done to compare multiple mass casualty incidents and find commonly shared lessons. This paper aims to determine whether there are any similarities among three mass casualty events - 2005 Hurricane Katrina, the 2009 Aurora Theatre Shooting, and the 2013 Boston Marathon Bombing. Because the response to the 2013 Boston Marathon Bombing was the most seamless among the three, the most in-depth investigation was done on this incident. Through the examination, the study will also prove if any of the lessons learned from these events can be implemented in future mass casualty incidents. To do so, many current reports and literature reviews were analyzed. The conclusion gained from this study is that there are indeed commonly occurring challenges in disasters and various aspects of disaster preparedness that require practice and preparation. In addition, learning from others' unfortunate mass casualty incidents and their lessons is an important part of strengthening the existing disaster preparedness systems.

The structural evolution of the Sunshine Springs thrust area, Marathon Basin, Texas

Kraft, Jennifer Lucille 09 June 2011 (has links)
Detailed mapping (1:6,000) of Lower Ordovician through Lower Pennsylvanian strata, exposed in the vicinity of the Sunshine Springs thrust fault, shows that the thrust ramps up-section twice in a direction parallel or subparallel with the thrusting, and that the geometry of folds can be attributed to their proximity to the two closely spaced ramps. The lower ramp is a frontal ramp which originated as a forelimb thrust through the overturned limb of a tight anticline-syncline fold couplet. The upper ramp cuts up-section through a thin, upper Paleozoic flysch sequence where the Sunshine Springs thrust becomes imbricated. Directly above the lower ramp, in the upper plate, is a broad symmetrical anticline which has a geometry similar to a fault-bend fold. Forward of the lower ramp is a large wavelength, flat-bottomed syncline, and behind the lower ramp is a series of tight to isoclinal overturned folds. As a result of fault-bend folding and continued shortening of the ramp region, upper plate folds characteristically have a larger amplitude than folds of the lower plate. Just forward of the lower ramp in the footwall is the tightly folded and truncated syncline of the syncline-anticline fold couplet. The rest of the lower plate section is only mildly deformed. A composite, down-structure cross section drawn parallel with the direction of thrusting shows that the Peña Colorada synclinorium has been transported along the Sunshine Springs thrust approximately 3.8 km. Shortening, as deduced from folding in this study alone, is 20 percent, and when the shortening by the thrust is also considered, the total amount of shortening equals 52 percent. A major left-lateral strike-slip system, trending WNW, approximately parallel with the thrusting direction, offsets the Sunshine Springs thrust fault. Strike-slip and dip-slip displacements can be calculated from a displaced fold axis of the lower plate syncline, and are 335 m and 90 m, respectively. In the vicinity of this strike-slip system, the axial traces of folds change from a dominantly southwesterly trend to a more southerly trend. The regional extent of the fault system within the Marathon Basin, and its correspondence with the change in major fold axes orientations suggests that the fault zone is a regional tear which formed in response to the impingement of the Marathon thrust front against the Diablo Platform during the Pennsylvanian Period. / text
