Idamari Törnberg & Marcus Tillberg (2011). Nu gäller det! Varför slutar då ungdomar spela ishockey? – En kvantitativ enkätstudie om fortsatt eller avslutande ishockeykarriär efter uttagningarna till distriktsförbundslag i Västerbottens län. (Now is the time! Why do teenagers stop playing ice hockey? – A quantitative survey study about continued or ending ice hockey career after tryout to Team Västerbotten) Bachelor Essay in Swedish. Umeå: Umeå University, Department of education. Abstract This Bachelors thesis is a survey study on why talented teenagers in the county of Västerbotten, Sweden dropout of, or proceed the sport ice hockey. The study was made in collaboration with the ice hockey association of Västerbotten to find out how many of the boys born in 1993 and 1995 that has been on tryout for team Västerbotten that quits and continues and the reason for that. A survey was sent out to 138 of the teenagers that had been on these tryouts to examine the reasons and opinions on dropouts and what action that needs to be made to prevent this. The response rate was 57 % and a possible reason for that can be that they who didn’t respond are dropouts. It turned out that most of the respondents is still playing ice hockey, just a few had dropped out and the biggest reason is the fact that ice hockey is fun no matter if they made the team or not. Furthermore the study showed that the there isn’t just one reason to quit or continue, it’ a mix of reasons.

<p>The main question in this thesis has been to see how the brand strategy of Linköpings Hockey Club has changed during the years in the Swedish elite league. We will also look at the content of the brand, as well as the association as the city of Linköping. This thesis will also see the sponsorship view of the development of the brand, because of the sponsorship power to help the association to build and strengthen the brand.</p><p>We have been interviewing important persons at the association Linköpings Hockey Club and also done interviews with a few sponsorship partners to get important information to analyze.</p><p>As an association it is of outmost importance to disseminate the association’s image in the right way, which Linköpings Hockey Club has according to their sponsorship partners. The association has during the last years been working hard to take care of and strengthen the brand, which can be seen among the sponsorship partners. The way they have been strengthening the brand can be seen on the basis of different aspects, such as events and collaboration on different levels.</p> / <p>I uppsatsen har vi valt att utgå från frågeställningen hur varumärkesstrategin inom Linköpings Hockey Club har förändrats under åren i elitserien. Vi kommer även att se på innehållet i varumärket, såväl för föreningen som för Linköping som kommun. Uppsatsen kommer även att ta in sponsorers synvinkel på föreningens utveckling av varumärket, detta eftersom sponsorerna är av stor vikt för att såväl kunna stärka som bygga varumärket på ett bra sätt.</p><p>För att få fram ett material att analysera har intervjuer gjorts hos Linköpings Hockey Club med relevanta personer samt att ett antal enkäter gått ut till utvalda sponsorer vilka vi även intervjuat personligen.</p><p>Det gäller för en idrottsförening att se till att få ut den tänkta imagen på rätt sätt, vilket Linköpings Hockey Club anses har gjort i samarbetspartnernas ögon. Linköpings Hockey Club har under de senaste åren aktivt jobbat med att stärka och vårda sitt varumärke, vilket märks bland annat vid kontakten med sponsorerna. Sättet de stärkt det på kan ses utifrån olika aspekter, såsom olika evenemang och samarbeten på olika plan. För ett idrottslag är det väldigt viktigt att skapa ett starkt varumärke eftersom det drar såväl sponsorer, publik som nya spelare till sig. Även ekonomin kan ses som en viktig aspekt för att lyckas få ut sitt varumärke. Den utvidgning som föreningen gjort i och med Linköpings Fotbolls Club har de gjort på ett bra sätt, vilket kan vara en bidragande orsak till att varumärket har stärkts på marknaden och även fungerar som en bidragande faktor till att invånarna i Linköping blir mer medvetna om LHC: s image.</p>

Ice hockey is a contact sport played in a cold environment which leads to assumptions that players are not exposed to a thermal challenge. The purpose of this study was to test the hypothesis that the wearing of hockey protective equipment during an exercise protocol designed to simulate a hockey game would induce a thermal challenge and lead to decrements in performance. In order to test this hypothesis and qualify the physiological responses, subjects performed a standardized protocol performed on a stationary cycle ergometer in an environmental chamber set at typical (12ºC) ice hockey ambient conditions. The simulation was performed twice; once while wearing cotton undergarments only (NP), and once while wearing cotton undergarments and the typical protective equipment worn during a hockey game (P). Work intensity during each trial was held constant and was evaluated by examining mean power output, which was similar under both P and NP conditions (348.2 W vs 352.08 W, P > 0.05) P vs NP, respectively. Body (37.18 ºC vs 36.58 ºC) and skin temperatures (34.12 ºC vs 28.85 ºC) were elevated in P vs NP, respectively (P<0.05). Core temperatures (37.50 ºC vs 37.41ºC) displayed a trend towards being higher in P vs NP particularly during the third period of simulation (P = 0.053). Sweat loss as a percent of body mass was greater in P vs NP (2.57% vs 1.18%, respectively P<0.05), which led to an increase in plasma osmolality (287 vs 283 mosmol/kg H2O, respectively P<0.05) working heart rate (83.7% vs 78.8% of maximum heart rate), resting heart rate (63.4% and 55.9% of maximum heart rate), and urine specific gravity (1.026 vs 1.017) for P vs NP respectively (each P<0.05). The drop-off in power from pre to post simulated game was examined in both conditions by the use of five repeated maximal six second sprints interspersed with 24 seconds of recovery. The drop-off in both peak (12.0% vs 0.2%) and mean power (14.5% vs 2.7%) was greater in P versus NP (P<0.05). Plasma lactate concentration was higher following the simulated game in P vs NP (9.64 vs 5.96 mmol/L, P<0.05) as was plasma norepinephrine (2274.0 vs 1366.9 pg/ml, P<0.05). Rating of Perceived Exertion increased by 30-53% in the P condition (P<0.05) even though power outputs were equivalent. The elevated body temperature and increased water loss appeared to increase glycolytic flux, which when coupled with the consequences of thermal stress, reduced power output and led to the perception of elevated work intensities during the simulated game.

BAKGRUND: Ishockey är en stor idrott med över 80000 aktiva spelare i Sverige. SYFTE: Syftet med denna studie var att fastställa huruvida det finns korrelation mellan tester rekommenderade av Svenska Ishockeyförbundet och prestationsförmåga på is. Vidare skulle testresultaten ställas i relation till antropometriska värden. METOD: Studiepopulationen rekryterades från hockeylag i division I. Testerna 1RM knäböj, stående längdhopp samt sergants jump utfördes enligt Svenska Ishockeyförbundets rekommenderade förfarande. Prestationsförmåga på is mättes genom 17 m sprintlopp. Korrelationen mellan testerna och prestation på is beräknades med pearsons korrelationskoeffecient. P&lt;0.05 betraktades som signifikant. RESULTAT: Totalt rekryterades 34 ishockeyspelare från division 1 (100 % män, medel ± SD: ålder 22,7 ±2.24 år; vikt 85,3 ±6,4 kg; längd 182 ±6 cm). Av utförda tester var det endast 1RM knäböj/kroppsvikt-ratiot som med statistisk signifikans visades korrelera med prestationsförmågan på is (r=0,389, p=0,049). Övriga tester uppvisade ingen statistisk signifikans. SLUTSATS: Studiens resultat pekar mot att det finns en svag statistiskt signifikant korrelation mellan 1RM knäböj/kroppsvikt-ratio och sprintförmåga på is. Knäböj/kroppsvikt-ratiot svarar dock endast för en liten del av prestationsförmågan på is, varvid knäböjens starka position som grundövning utanför isen bör ifrågasättas. / BACKGROUND: Ice hockey is a large sport with over 80000 active players in Sweden. PURPOSE: The aim of this study was to determine whether there are correlations between tests recommended by the Swedish Ice Hockey Federation and on-ice performance. The results were also to be examined in relation to antropometric values. METHOD: The studypopulation was recruited from Swedish tier-III teams. The 1RM squat, standing long jump sand sergants jump were performed as described by the Swedish Ice Hockey Federations guidelines. On-ice performance was measured by a 17m sprint. The correlation between off- and on-ice tests were calculated using pearsons correlation coefficient. Statistical significance was set to P&lt;0.05. RESULTS: Thirtyfour male ice hockey players from Swedish tier-III were recruited for the study (100% men, mean ± SD: age 22,7 ±2.24 years; weight 85,3 ±6,4 kg; length 182 ±6 cm). Out of the performed tests only 1RM squat/bodywight-ratio showed a statistical significant correlation to on-ice performance (r=0,389, p=0,049). The other tests did not show statistical significance. CONCLUSION: The results points towards a weak statistical significant correlation between 1RM squat/bodywight-ratio and on-ice sprinting ability. The 1RM squat/bodyweight-ratio however explained a small portion of on-ice performance, hence the squats strong position as basic exercise off-ice should be questioned.

This study investigated the effects of progressive dehydration by 1.5-2.0% body mass (BM) (NF) on core temperature (Tc), heart rate (HR), on-ice performance, and mental fatigue during a 70-min scrimmage, compared to maintaining BM with a carbohydrate-electrolyte solution (CES). Compared to CES, Tc was significantly higher throughout the scrimmage in NF. Players in NF had reduced mean skating speed and time at high effort between 30-50 min of the scrimmage. Players in NF committed more puck turnovers and completed a lower percentage of passes in the last 20 min of play. Post-scrimmage shuttle skating time was higher in NF. Hockey fatigue questionnaire total score and Profile of Mood States fatigue score was higher in NF. The results indicate that mild dehydration compared to maintaining BM with a CES resulted in increased Tc, decreased skating and puck handling performance, and increased mental fatigue during an ice hockey scrimmage. / Gatorade Sports Science Institute, Natural Sciences and Engineering Research Council of Canada

In male athletes from different sports, isokinetic knee extensor, and in orienteers also plantar flexor peak torque (PT), contractional work (CW) and integrated surface electromyograms (iEMG) were analysed. Single contraction PT, CW and iEMG in sprinters and marathon runners were signi­ficantly correlated to the cross-sectional area (CSA) of m. quadriceps, and to the Type II fibre area of m. vastus lateralis. When correcting PT, CW and iEMG for CSA of m. quadriceps, such correlations were found only for Type IIA fibre area at 180° s~1. Elec- tromyographically, m. vastus lateralis (biopsied muscle) was representative for m. quadriceps. Calculated optimal mean power (CW s~1) and electrical efficacy (CW/iEMG) approximated for sprinters 450° s-1 and for marathon runners 270° s~1, i.e. velocities at or above the upper limit of the dynamometers. In orienteers, plantar flexor PT increased during winter training, but decreased during competitive season. Knee extensor PT increased over the whole year. At 30 and 60° s~1 only knee extensor PT was negatively associated with the running velocity at onset of blood lactate accu­mulation (VOBLA)- Changes in VOBLA during winter period were negatively associated with changes in knee extensor PT at 180° s~1. During competitive season, changes in Vobla were negatively associated with the ratio quality : quantity running. In ice hockey players PT varied non-systematically with training and games. The biopsy specimens of marathon runners showed irregular fibre shapes, an in­creased amount of connective tissue and central fibre nuclei, indicating an early strain disease or functional adaptation to extreme demands. During repetitive contractions in sprinters and marathon runners, fatigue, i.e. slope of decline in CW, was significantly associated with the Type II fibre area of m. vastus lateralis. For knee extensors of sprinters, ice hockey players and orienteers, a steep de­crease in CW/iEMG was observed. In contrast, knee extensors of marathon runners and plantar flexors of orienteers showed an almost unaltered CW/iEMG throughout the test. The knee extensor endurance level (CW/iEMG) was significantly correlated to the maximal oxygen uptake. In orienteers, an increase in endurance level of both tested muscle groups during winter training parallelled an increase in VOBLA and V02obla- In hockey players, fatigue and endurance pattern (CW and CW/iEMG) changed non-systematically with training and games. In conclusion, isokinetic measurements and iEMG reflect the structural properties of the knee extensor muscles in sprinters and marathon runners. The demonstrated characteristics and changes in leg muscle function in different groups of athletes apparently reflect varying demands from different sports activities. / <p>S. 1-31: sammanfattning, s. 33-84: 6 uppsatser</p> / digitalisering@umu

Ice hockey is a sport known for its speed and skill. However, its intensely physical nature is associated with the potential risk of injury, which has become a major public controversy in Canada (Cusimano, Sharma, Lawrence, et al., 2013; Emery et al., 2010). Epidemiological research has adequately documented the frequency and severity of injury (King & LeBlanc, 2006; Yard & Comstock, 2006). Yet, because of methodological limitations and the lack of systematic and mandatory injury prevention strategies implemented nationwide, injuries remain high (Cusimano, Nastis, & Zuccaro, 2013; Emery et al, 2010). An alternative methodology, combined with broadening injury definitions can provide a more detailed assessment of the risks of, and circumstances, around injury. A methodology, based primarily on observational techniques, was utilized to examine injury in body checking hockey when it is first introduced to youth players. Injury was defined as ‘any physical trauma that has occurred as a result of participation in an organized competition’ including four categories of injury severity. In a comparison of Ontario Peewee (ages 11-12) with Québec Bantam (ages 13-14) boys hockey, no significant differences were found in overall injury (χ2: 0.22; p:0.64), however, there were significant differences in frequency of body checking related injury; 76% versus 59% (χ2:4.76; p:0.03). The odds of being injured due to body checking are 2.158 times higher in Peewee (βex 2.158; 95%CI: 1.07-4.34; p:0.03) indicating no increased risk of injury when body checking is introduced later while delaying introduction reduces the frequency of body checking related injury. Ongoing public debate in Canada concerning safety in youth hockey is understood through the theoretical lens of discourse (Foucault, 1972, 1990). The dominant discourse in Canada around hockey is based in a traditional, physically dominant model, where intense physical contact is not only inevitable but desirable. The reverse discourse prioritizes the safety of participants over the potential of lessening the intense physicality of the Canadian style of play. These competing discourses create tension and ambivalence amongst safety advocates and conservative hockey practitioners and enthusiasts. The emotionality of hockey stakeholders often overwhelms logic regarding safety decisions, ultimately impacting progressive injury prevention initiatives.

This thesis will discuss the results of a two-year 90 game study to consider the role violence and aggression plays in competitive minor hockey and its role as a mechanism for injury. The second objective of this thesis was to determine the contextual factors that lead to injury on the ice. Using a mixed methods approach, the study followed three minor hockey teams from the Ottawa-Gatineau region over two sporting seasons. The study found that players are not being injured due to aggressive or violent play but rather players are being hurt within the rules of the game. The contextual factors that were shown to lead to injury included: (1) body-checking, (2) time of the game, (3) player’s body mass, (4) position played and (5) legal plays. Injuries were also broken down by anatomical site (head/neck, upper body and lower body); the upper body was affected by injury most.
