    Opinn√§ytety√∂ on toteutettu toimeksiantona Arctic Powerille, joka on Rovaniemen ammattikorkeakoulun alainen tutkimus-, kehitys- sek√§ testauspalveluyksikk√∂. Ty√∂n tarkoituksena on selvitt√§√§ moottorikelkkojen liikennek√§ytt√§ytymist√§ Rovaniemen seudulla. Tarkoitus oli suunnitella ja toteuttaa liikenteenvalvontaj√§rjestelm√§ talvella 2012¬¨¬¨¬¨‚Äď2013 valitulla moottorikelkka-reitill√§. Liikenteenvalvontaj√§rjestelm√§n tulee mitata seuraavat suureet: nopeus, p√§iv√§m√§√§r√§, ajoneuvon pituus ja kellonaika. Valvontaj√§rjestelm√§ on toteutettu k√§ytt√§m√§ll√§ Viacount II -liikennelaskuria, joka toimii kantoaaltotutkan periaatteella. Datan l√§hetys Arctic Powerin tietokantapalvelimelle on toteutettu HCP Roadstar -modeemilla ja modeemi on ohjelmoitu Java-ohjelmointikielell√§ tarkoitukseen sopivaksi. Ohjelmoinnissa k√§ytettiin Netbeans-ohjelmaa. Tuloksena saatiin tietoa moottorikelkkojen liikennek√§ytt√§ytymisest√§ nopeuksien ja ajom√§√§rien muodossa. Ajonopeudet ja -m√§√§r√§t viittasivat maltilliseen ajok√§ytt√§ytymiseen moottorikelkkareitill√§. Tulokset antavat my√∂s viitteit√§ ajonopeuksien ja -m√§√§rien kehittymisest√§ kelkkareitin kunnostuksen ja s√§√§olosuhteiden osalta. Tulevaisuuden kehitysmahdollisuuksien tarkasteleminen osoitti, ett√§ liikenteenvalvontaj√§rjestelm√§√§ on mahdollista jatkossa kehitt√§√§ l√§hes huoltovapaaksi.This thesis was commissioned by Arctic Power. Arctic Power is part of Rovaniemi University of Applied Sciences and it works as a research, development and testing center. The goal of this work was to examine how the traffic behavior of snowmobiles works in Rovaniemi. The purpose was to design and implement a traffic control system in the winter of 2012 and 2013 on a chosen snowmobile route. The traffic control system had to measure the speed, the date, the length of the vehicle and the time. The traffic control system was implemented with Viacont II, which operates with the CW radar. The data transmission to the database server of Arctic Power was implemented with the HCP Roadstar modem. The modem was coded with Java programming to meet the requirements. The Netbeans program was used in the programming. The results gave information about the amounts and the speeds of the snowmobiles. The Speed and the driving amounts indicated that the driving behavior on the snowmobile route was quite calm. The results also indicated the development of the speeds and the amounts after the route maintenance and weather conditions. In the future it will be possible to develop the traffic control system to make it nearly maintenance free

    Sports Clubs Can Contribute to the Physical Activity of Children and Adolescents in More Diverse and Sustainable Activities

    An increasing number of children are taking part in supervised club activities, starting at a younger age. They also start focusing on one sport at a younger age, and the dropping out of club activities starts already at the age of 11. These changes are challenging the current club activities. There has been a large increase in participation in club activities. In the 1990s, just over 30% of children and young people in Finland practiced sports in a club, while today, the participation rate has risen to 60%. The age at which children start participating in club activities has decreased by an average of one year per decade. Those born before the 1950s typically started participating in clubs at the age of 12, compared with an average age of six today. This change means that children specialise in one sport and then drop out of club activities too early. As a result, the hobby does not continue as far into adolescence as it should. This increases the likelihood of inactivity in adolescence and further on in adulthood. The clubs do not need to fix the insufficient physical activity of the population alone, but they have the potential to develop their own activities in promoting physical activity and physical education, as well as their cooperation with other actors. This policy brief is the third and last in its series from the Healthy Lifestyles to Boost Sustainable Growth (STYLE) project, combining interdisciplinary knowledge on trends in transport and physical activity. Interpreting them through infrastructure and service designs and changing lifestyles, we generate insight on novel business opportunities and intervention models that induce physical activity. This provides innovative pathways towards current national policy targets and promotion of the societal vision. The project is funded by the Strategic Research Council at the Academy of Finland.

    Declining Fitness Levels are a Challenge to Well-Being in Finland ‚Äď effective actions to increase physical activity and reverse the downward spiral of fitness

    Get PDF
    The physical functional capacity of Finns has been declining for decades: ‚ÄĘ The number of young men entering military service with poor physical fitness has increased eightfold ‚ÄĘ The number of men with poor muscle fitness has increased manifold ‚ÄĘ The average weight of new recruits has increased by 8 kg ‚ÄĘ The results of the MOVE! measurements of schoolchildren show the same alarming trend also in schoolchildren. As a result of the prolonged negative trend described above, the physical fitness of Finns of working age will continue to deteriorate significantly also in the coming decades. By 2040, according to a very conservative forecast, only very few people aged 50 or over in Finland will be in good physical fitness. This vicious cycle will lead to an increasing incidence of non-communicable diseases (such as type 2 diabetes, depression, cardiovascular diseases, musculoskeletal diseases, etc.). Being ill leads to increased sickness absences, earlier disability, and lower labour productivity. Unless this negative trend can be reversed, we will not be able to extend working life, the economic backbone of the state, municipalities, and cities will be broken, and the base of the national defence (the reserve army) will not hold up. The steady decline in fitness and increase in obesity will cause problems across all sectors of government. No amount of economic growth will be enough if the downward spiral of the physical functional capacity and fitness of working-age Finns is not reversed. We need multiple, simultaneous, effective measures across all sectors, at the national as well as the local level. These simultaneous, multi-sectoral actions require strong leadership and coordination between different sectors. Therefore, at the national level, the Prime Minister's Office and, at the local level, the municipal or city management group, are capable actors to lead these simultaneous measures that are needed across sectors of government. Effective measures are needed for those in the working life today who are struggling with their physical functional capacity, as well as to ensure the functional capacity of the workforce in the future. This policy brief is the second in its series from the Healthy Lifestyles to Boost Sustainable Growth (STYLE) project, combining interdisciplinary knowledge on trends in transport and physical activity. Interpreting them through infrastructure and service designs and changing lifestyles, we generate insight on novel business opportunities and intervention models that induce physical activity.

    Predicting Adolescents’ Physical Activity Intentions : Testing an Integrated Social Cognition Model

    Get PDF
    Background: Few adolescents meet guideline levels of physical activity associated with good health, highlighting the need for intervention. Interventions promoting adolescents’ physical activity should be guided by research applying behavioral theory to identify potentially modifiable correlates and associated processes. We applied an integrated social cognition model to identify theory-based constructs and processes that relate to physical activity intentions in a secondary analysis of two samples of Finnish adolescents using a correlational design. Method: Participants in the first sample (n = 455) completed self-report measures of social cognition constructs from theory of planned behavior, habit, self-discipline, and past and current physical activities. Participants in the second sample (n = 3878) completed identical measures plus measures of socio-structural and socio-environmental factors. Participants from the first sample also wore accelerometers for 1 week. Hypothesized model effects were tested using variance-based structural equation modeling in data from the first sample and subsequently confirmed in a pre-registered analysis of data from the second sample. Results: Across both samples, habit, attitude, perceived behavioral control, and self-reported past behavior were associated with physical activity intention. Effects of self-reported past physical activity on intention were partially mediated by social cognition constructs. Effects of accelerometer-based physical activity were small by comparison. Effects of socio-structural and socio-environmental factors on intention in the second sample were partially mediated by the social cognition constructs. Conclusion: Results corroborate beliefs and habit as consistent correlates of adolescents’ physical activity intentions and provide preliminary evidence that social cognition constructs account for effects of socio-structural and socio-environmental factors on intentions.publishedVersionPeer reviewe

    Urheiluseurat voivat liikuttaa lapsia ja nuoria entistä monipuolisemmin ja kestävämmin

    Suomessa liikuntaseurat tavoittavat yli puolet lapsista ja nuorista, ja vain yksi kymmenestä ei ole ollut seuratoiminnassa ollenkaan. Lasten ja nuorten vähäinen liikkuminen näkyy myös seurojen toiminnassa muun muassa heikkona kestävyyskuntona tai heikkoina motorisina taitoina. Seurojen ei yksin tarvitse ratkaista liikkumisvajetta, mutta seuroilla on mahdollisuus kehittää omaa toimintaansa tukemaan liikkumisen lisäämistä ja monipuolistamista. Tämä tukee myös seurojen urheilullisia tavoitteita. Tunnistamme urheiluseurojen itsenäisen aseman osana vapaata kansalaistoimintaa sekä seurojen moninaisuuden niin lajien kuin paikallisolosuhteiden suhteen. Tässä julkaisussa esiteltävien suositusten tarkoituksena onkin herättää kriittistä pohdintaa nykyisestä seuratoiminnasta, sekä tarjota seuroille keinoja olla mukana liikkuvamman Suomen rakentamisessa.

    Suomalaisten kunto rapistuu. Varusmiespalveluksen aloittajien kestävyyskunto on heikentynyt asteittain 1970-luvun lopulta nykypäivään. Huonokuntoisia varusmiehiä on jo kolmasosa palveluksen aloittajista, määrä on kahdeksankertaistunut. Keskimääräinen paino puolestaan on noussut kahdeksan kiloa. Kestävyyskunto heikentyy edelleen noin neljänneksen työuran aikana. Maltillinen ennuste kertoo kunnon heikentymisen jatkuvan lähivuosina. Tämä kehitys haastaa hyvinvointi-Suomen. Esitämme tässä STYLE-tutkimushankkeen politiikkasuosituksessa valtakunnallisen ja paikallisen tason toimia, joita samanaikaisesti toteuttamalla kestävyyskunnon lasku voidaan pysäyttää ja edelleen kääntää nousu-uralle.

    Finnish late adolescents' physical activity during COVID-19 spring 2020 lockdown

    Get PDF
    Background Physical activity (PA) is recognised as one of the leading and effective strategies to prevent non-communicable diseases that boosts the immune system to fight against diseases. Closures of schools, sport clubs and facilities because of COVID-19 reduced the opportunities to participate in PA. We aimed to examine physical activity levels of late adolescents, the contexts to be physical active and its changes during the spring 2020 lockdown. Methods A national representative sample of late adolescents in general upper secondary school (n = 2408, females = 64%, mean age = 17.2y, SD = 0.63) completed self-report online surveys on PA behaviours between March and June 2020. Multinominal logistic regression analyses were performed to identify correlates with PA, and decision tree analyses to ascertain the perceived changes on PA during lockdown based on sport club aspirations and levels of PA. Results Among the late adolescents, the distribution of PA frequency was 23% (0-2 days/week), 35% (3-4 days/week), 30% (5-6 days/week) and 12% (7 days/week), and differences between males and females were not statistically significant. Participation in both indoor and outdoor PA were 50 times more likely to report daily PA (OR = 54.28, CI = 15.16-194.37) than non-participation. A quarter of late adolescents were not part of a sports club, yet their PA levels increased. Although sports club members generally perceived they did less PA during lockdown, over a third of sport club members with competitive aspirations reported daily PA. Conclusions Overall, most late adolescents reported their PA levels decreased during lockdown. Findings from this study continue to demonstrate factors associated with PA in the context of the COVID-19 lockdown

    Physical activity from adolescence to young adulthood : patterns of change, and their associations with activity domains and sedentary time

    Get PDF
    BackgroundLongitudinal studies demonstrate an average decline in physical activity (PA) from adolescence to young adulthood. However, while some subgroups of adolescents decrease activity, others increase or maintain high or low activity. Activity domains may differ between subgroups (exhibiting different PA patterns), and they offer valuable information for targeted health promotion. Hence, the aim of this study was to identify PA patterns from adolescence to young adulthood; also to explore the associations of (i) changes in PA domains and in sedentary time, (ii) sociodemographic factors, and (iii) self-rated health with diverging PA patterns.MethodsThe observational cohort study data encompassed 254 adolescents at age 15 and age 19. K-means cluster analysis for longitudinal data was performed to identify participant clusters (patterns) based on their accelerometry-measured moderate-to-vigorous PA (MVPA). Logistic regressions were applied in further analysis.ResultsFive PA patterns were identified: inactivity maintainers (n=71), activity maintainers (n=70), decreasers from moderate (to low) PA (n=61), decreasers from high (to moderate) PA (n=32), and increasers (n=20).At age 15, participation in sports clubs (SC, 41-97%) and active commuting (AC, 47-75%) was common in all the patterns. By age 19, clear dropout from these activities was prevalent (SC participation mean 32%, AC 31-63%). Inactivity maintainers reported the lowest amount of weekly school physical education.Dropout from SC - in contrast to non-participation in SC - was associated with higher odds of being a decreaser from high PA, and with lower odds of being an inactivity maintainer. Maintained SC participation was associated with higher odds of belonging to the decreasers from high PA, and to the combined group of activity maintainers and increasers; also with lower odds of being an inactivity maintainer. Maintenance/adoption of AC was associated with decreased odds of being an inactivity maintainer. Self-reported health at age 19 was associated with the patterns of maintained activity and inactivity.ConclusionsPA patterns diverge over the transition to adulthood. Changes in SC participation and AC show different associations with diverging PA patterns. Hence, tailored PA promotion is recommended.Peer reviewe

    Mismatch, empowerment, fatigue or balance? Four scenarios of physical activity up to 2030 in Finland

    Get PDF
    Sedentary lifestyles and the lack of physical activity (PA) are a major concern among all age groups, and current generations tend to be less fit than the previous ones in the Western World. At the same time, there is an urgent need to cut transport-related carbon dioxide (CO2) emissions. Major gains can be foreseen if current car-centred lifestyles and sedentary behaviour are addressed from an integrated perspective. In this study, we explore future scenarios in the intersections of PA and active lifestyles as well as related environmental and health benefits in Finland. We used a disaggregative Delphi approach to examine the topic. Although frequently used in health-related research, Delphi has rarely been used in exploring alternative futures or non-consensus. The study design was based on a mixed-methods approach where we combined both qualitative and quantitative data analysis. Building on the experts’ perceptions on alternative futures, we formulated four scenarios for PA up to 2030, which we named Mismatch, Empowerment, Fatigue and Balance. The scenarios may be utilised as guides in developing future policies and decision-making, and to build better futures. Our scenarios demonstrate that alternatives do exist, and actions can be realigned with the positive scenarios of Empowerment and Balance. The physically inactive scenarios of Mismatch and Fatigue represent avoidable scenarios.</p
