A Visual Programming Language in Virtual Reality : A Usability Evaluation and Its Potential for Reducing Sedentary Behavior / Ett Visuellt Programeringsspråk I Virtual Reality : En användbarhetsutvärdering och dess potential för att minska stillasittande beteende

Jonsson, Adam January 2023 (has links)
Sedentary behavior is linked to numerous adverse effects on a person’s health, such as obesity, depression, and a higher risk of cardiovascular events. Professions that are primarily sedentary have increased due to the growth of office-related occupations, one of which is software engineering. A potential intervention to reduce sedentary behavior is to utilize new interactive technologies such as virtual reality (VR) to change the work context and allow software engineers to interact with their work environment in a more embodied manner. This study has designed and evaluated a visual programming language (VPL) in VR for its potential to reduce sedentary behavior and its compromise on usability. Ten participants solving simple programming tasks using the VPL in VR revealed the potential of reducing continuous sedentary behavior with light physical activity. The main contributor to this activity was the need to walk to and from interactive elements placed a few meters from each other in the design. However, the usability evaluation showed that users modify the environment over time to reduce this distance such that less walking is needed. In contrast, movement induced by navigating to code blocks and getting an overview of the current state of the work had positive marks and a high contribution to the observed movement. Lastly, the second contributor to physical activity was moving blocks around. The usability evaluation indicates that using VR controllers was slower than using a mouse but allowed more precise interactions. / Stillasittande beteende har ett flertal negativa effekter på en persons hälsa, såsom obesitas, depression och en högre risk för kardiovaskulära händelser. Yrken som främst är stillasittande har ökat på grund av tillväxten av yrken som är kontorsbaserade, till exempel mjukvaruutveckling. Ett potentiellt ingripande för att minska stillasittande beteende är att använda nya interaktiva tekniker, så som virtuell verklighet (VR) för att förändra arbets kontexten och låta mjukvaruingenjörer interagera med sin arbetsmiljö på ett mer förkroppsligat sätt. Denna studie har utvecklat och utvärderat en visuellt programmeringsspråk (VPL) i VR för dess potential att minska stillasittande beteende och dess kompromiss på användbarhet. Tio deltagare som löste enkla programmeringsuppgifter med hjälp av VPL i VR visade potentialen för att bryta upp stillasittande beteende med lätt fysisk aktivitet. Den främsta bidragsgivaren till den observerade aktivitet var behovet av att gå till och från interaktiva element placerade med några meter avstånd från varandra. Utvärderingen visade dock att användare modifierar miljön över tid för att minska detta avstånd så att man behöver gå mindre. Däremot hade rörelser när man behöver navigera till kodblock och få en överblick över arbetet positiva kommentarer och ett högt bidrag till den observerade aktiviteten. Slutligen var aktiviteten att flytta runt block den handling som bidrog näst mest till den observerade fysisk aktivitet. Utvärderingen av användbarheten indikerar att VR-kontroller var långsammare än att använda en mus men tillät mer tillförlitliga interaktioner.

Utvärdering av implementering : Fysisk aktivitet under arbetstid

Wallin, Elsa, Wendelhag, Moa January 2024 (has links)
Introduktion: Långvarigt stillasittande och repetitivt arbete har visat på negativa kroppsliga effekter som till exempel muskuloskeletala besvär och ökad risk för hjärt-kärlsjukdomar. Som motvikt finns evidens för att variation under arbetsdagen i form av korta, aktiva pauser ger positiva effekter där så lite som två minuter styrketräning per dag räcker. Att implementera aktiva pauser är dock utmanande och flera faktorer spelar in både hos medarbetare och chefer.  Syfte: Syftet är att undersöka prevalensen av muskuloskeletal smärta före och efter implementering av aktiva styrkepauser, i form av fysisk aktivitet under arbetstid, på Klinik A. Studien ska även undersöka deltagandet och attityden till implementeringen av aktiva styrkepauser på klinik A, B och C.  Metod: Uppföljning av implementering av aktiva styrkepauser infördes på tre avdelningar på ett större sjukhus. Medarbetarna på avdelningarna fick en enkät, utformad av författarna, utskickad via mail som frågade om deltagande och attityd av implementeringen. En avdelning besvarade ytterligare en enkät om muskuloskeletal smärta. Denna enkät var en ett-årsuppföljning mellan oktober 2022 och oktober 2023.  Resultat: Resultatet från besvärsenkäten visade att muskuloskeletala besvär i nacke, axlar och övre rygg minskade efter ett år. Implementeringsenkäten visade att det var 30 av 32 som deltog i de aktiva styrkepauserna. Deltagarna hade en positiv attityd och upplevelse av implementeringen. Stöttning från chefer och starka individuella motivationsfaktorer, såsom tävlingsmoment, visade sig vara viktiga aspekter.   Konklusion: Den minskade muskuloskeletala smärtan stämmer överens med andra studier. Majoriteten av de som svarade på implementeringsenkäten deltog i de aktiva pauserna och hade en positiv attityd till de aktiva styrkepauserna. Mer forskning i olika arbetsmiljöer krävs dock för att säkerställa hur en lyckad implementering av aktiva styrkepauser ska genomföras.

Från stillasittande till aktivitet : En studie om spelifieringens påverkan på aktivitetsnivåer. / From Sedentary to Active : A Study on the Impact of Gamification on Activity Levels.

Warelius, Emil January 2024 (has links)
Denna studie undersökte effekterna av spelifiering på aktivitetsnivån hos individer med en övervägande stillasittande livsstil. Studien omfattade 14 deltagare i åldrarna 18-60 år, där 42.9% var män och 57.1% var kvinnor. Genom att integrera spelifieringselement som poäng, märken och topplistor i en mobilapplikation, syftade studien till att undersöka om dessa kunde främja fysisk aktivitet och bidra till hälsosammare beteendemönster. Studien använde både kvantitativa och kvalitativa metoder, där deltagarnas aktivitetsnivåer före och efter interventionen jämfördes genom statistiska tester. Resultaten visade dock ingen signifikant förändring i aktivitetsnivåer (p > 0,05). Den genomsnittliga upplevda aktivitetsnivån minskade marginellt från 6,00 till 5,86, medan genomsnittet för antal aktiva gånger per vecka ökade från 4,07 till 4,64. Den dagliga stillasittande tiden minskade något på arbetsplatsen från 4,43 till 3,86 timmar, men ökade utanför arbetsplatsen från 3,29 till 3,50 timmar. Slutsatsen drogs därmed att spelifiering baserat på studien inte gav en positiv förändring i deltagarnas aktivitetsmönster. Studien diskuterade möjliga förklaringar till dessa resultat, såsom interventionsperiodens längd och deltagarnas mottaglighet för spelifiering. Framtida forskning uppmuntras att utforska längre interventionsperioder, mer målgruppsanpassad spelifiering samt en bredare deltagargrupp. / This study examined the effects of gamification on the activity levels of individuals with a predominantly sedentary lifestyle. The study included 14 participants aged 18-60 years, of which 42.9% were men and 57.1% were women. By integrating gamification elements such as points, badges, and leaderboards into a mobile application, the study aimed to investigate whether these could promote physical activity and contribute to healthier behavior patterns. The study used both quantitative and qualitative methods, comparing participants' activity levels before and after the intervention through statistical tests. The results showed no significant change in activity levels (p > 0.05). The average perceived activity level decreased marginally from 6.00 to 5.86, while the average number of active times per week increased from 4.07 to 4.64. Daily sedentary time decreased slightly at the workplace from 4.43 to 3.86 hours, but increased outside the workplace from 3.29 to 3.50 hours. The conclusion was that gamification, based on the study, did not result in a positive change in participants' activity patterns. The study discussed possible explanations for these results, such as the duration of the intervention and participants' receptiveness to gamification. Future research is encouraged to explore longer intervention periods, more targeted gamification, and a broader participant group.

The seated inactivity trial (S.I.T.): physical activity and dietary outcomes associated with eight weeks of imposed sedentary behavior

Cull, Brooke J. January 1900 (has links)
Master of Public Health / Department of Human Nutrition / Mark Haub / Background: Time spent in sedentary behaviors, independent of physical activity levels, is a risk factor for chronic diseases and all-cause mortality. It is unknown whether physically active adults alter their dietary and/or physical activity behaviors in response to imposed sedentary time. The aim of this study was to determine whether imposing 10 hours of sedentary time per week for 8 weeks would alter physical activity and/or dietary profiles of physically active adults. Methods: Sixteen physically active, healthy young adults were randomized into either the no-intervention control (CON) group (n=8) or the sedentary-intervention (SIT) group (n=8). SIT participants attended monitored sedentary sessions for 10 hours per week (4 days; 2.5 hours) for 8 weeks. Assessments occurred at baseline, and weeks 4 and 8. Dietary information was collected through 3-day food records and physical activity was assessed through 7 days of accelerometry (Actical at the wrist). Results: There were no differences in physical activity profiles in SIT or CON groups when baseline and week-8 average (average weeks) were compared to the week-4 assessment. Differences in step counts comparing the average weeks and week 4 were not significantly different between CON and SIT groups (CON = 615.1 ± 3019.1, SIT= -1158.0 ± 3373.0 steps, p=0.287). There were no differences in sedentary (p=0.366), light (p=0.293), moderate (p=0.656) or vigorous (p=0.701) physical activity when average weeks were compared to one of imposed sedentary behavior. A greater number of SIT (4/8) participants had lower step counts during the imposed sedentary week, when compared to CON (1/8) participants. There was no difference (p>0.05) between CON and SIT groups for total calories consumed at any time-point. Caloric intake decreased significantly in the SIT group compared to the CON group (SIT = -27.9 ± 22.8%, CON = 10.0 ± 37.6%, p=0.028). More SIT (7/8) than CON (3/8) participants decreased caloric intake from baseline to 8 weeks (p>0.05). Conclusion: Physically active young adults did not alter physical activity profiles, but did decrease their caloric intake, in response to 8 weeks of imposed sedentary time. These findings may indicate a compensatory mechanism to imposed sitting in physically active adults.

Padrão de atividade física, comportamento sedentário e fatores associados na população adulta de Ribeirão Preto, SP-2006 - Projeto OBEDIARP / Physical activity pattern, sedentary behavior and correlates in the adult population in Ribeirão Preto, SP-2006 - OBEDIARP Project

Suzuki, Claudio Shigueki 20 December 2010 (has links)
Objetivos: Identificar o padrão de atividade física (AF) e de tempo sentado (TS), bem como os fatores associados, na população de 30 anos e mais, residente no município de Ribeirão Preto-SP, Brasil, em 2006 e comparar dois critérios utilizados para a classificação do padrão de AF: International Physical Activity Questionnaire - (IPAQ) e American College of Sports Medicine/American Heart Association (ACSM/AHA). Métodos: Estudo epidemiológico transversal, de base populacional, com processo de amostragem desenvolvido em três estágios. A variabilidade introduzida na terceira fração de amostragem foi corrigida pela atribuição de pesos amostrais, que levaram em consideração a taxa de não resposta e o número de unidades elegíveis em cada domicílio, originando uma amostra ponderada de 2197 participantes. Para avaliar o padrão de AF e do TS, utilizou-se o Questionário IPAQ (versão curta). Para identificar fatores associados ao padrão de AF, aplicou-se o modelo de regressão de Poisson, obtendo-se razões de prevalência, por pontos e por intervalos com 95% de confiança, em modelos uni e multivariados. Para a identificação dos fatores associados ao TS foram construídos modelos de regressão linear múltipla, obtendo-se os coeficientes angulares (?) e respectivos intervalos, com 95% de confiança, em modelos uni e multivariados. Todas as estimativas foram calculadas levando-se em consideração o efeito do desenho amostral. Para a comparação entre os critérios do IPAQ e do ACSM/AHA, utilizou-se a estatística Kappa, estimada por pontos e por intervalos com 95% de confiança. Resultados: Na amostra do estudo, 62,5% dos homens e 67,9% das mulheres apresentaram \"prática insuficiente\" de AF. Diferentes variáveis permaneceram associadas à \"prática insuficiente\" (PI) nos modelos finais. No sexo masculino, permaneceram: \"nº de horas de trabalho/dia\", \"nº de medicamentos consumidos nos últimos 15 dias\" e \"saúde auto-referida\". No sexo feminino, permaneceram: \"nível educacional\" e \"renda\". Em relação ao tempo sentado, em quase todas as categorias das variáveis estudadas, os homens apresentaram valores médios de TS maiores que as mulheres, sendo que, para o conjunto dos homens, a média diária foi 306,2 minutos e, para as mulheres, 270,3 minutos. Na análise multivariada permaneceram associadas ao TS as seguintes variáveis: \"sexo\", \"anos de escolaridade\", \"hábito de fumar\", \"gasto metabólico (Mets*min*semana-1)\", \"nº de horas de trabalho/dia\" e \"nº de antecedentes de obesidade\". As prevalências de prática suficiente de AF foram, em geral, discretamente mais elevadas quando aplicados os critérios do ACSM/AHA, em relação ao do IPAQ. A estatística Kappa indicou acordo satisfatório entre estes critérios (Kappa?1), em ambos os sexos, sendo os coeficientes gerais kmasc=0,95 (IC95% 0,83-1,06) e kfem=0,93 (IC95% 0,85-1,01). Conclusões: Os critérios do IPAQ e do ACSM/AHA apresentaram praticamente a mesma capacidade de classificação dos participantes quanto aos níveis de AF. Os resultados indicaram prevalência de PI e média de TS elevadas na população. As associações encontradas reforçam a necessidade de implantação de Programas específicos de promoção da prática de AF e diminuição do TS, tendo em vista que diferentes conjuntos de fatores permaneceram associados a estes desfechos. Tais Programas podem contribuir para a adoção de um estilo de vida saudável, bem como para a prevenção de doenças crônico-degenerativas nesta população. / Objectives: Identify the physical activity (PA) and sitting time (ST) pattern, as well as correlates, in the population aged 30 years and older living in Ribeirão Preto-SP, Brazil, in 2006 and compare two criteria used to classify the PA pattern: International Physical Activity Questionnaire - (IPAQ) and American College of Sports Medicine/American Heart Association (ACSM/AHA). Methods: A cross-sectional population-based epidemiological research was carried out using three-stage sampling. The variability introduced in the third sampling fraction was corrected by attributing sampling weights, which considered the non-response rate and number of eligible units at each household, resulting in a weighted sample of 2197 participants. To assess the PA and ST pattern, the IPAQ questionnaire (short version) was used. To identify PA correlates, Poisson\'s regression model was applied to estimate prevalence ratios, by point and 95% confidence intervals, in crude and multivariate models. To identify ST correlates, multiple linear regression models were used to estimate angular coefficients (?) and their respective intervals, at a 95% confidence level, in crude and multivariate models. All estimates were calculated taking into account the sample design effect. To compare IPAQ and ACSM/AHA criteria, Kappa statistics were used, by point and 95% confidence intervals. Results: In the study sample, 62.5% of men and 67.9% of women showed \"insufficient practice\" of PA. Different variables remained associated with \"insufficient practice\" (IP) in the final models. Among men, remained associated: \"number of work hours/day\", \"number of drugs consumed in last 15 days\" and \"self-related health\". Among women, remained associated: \"educational level\" and \"income\". With regard to sitting time, in almost all categories of the research variables, men showed higher ST means than women, with a daily average of 306.2 minutes for men, and 270.3 minutes for women. In multivariate analysis, remained associated with ST: \"gender\", \"years of education\", \"smoking\", \"metabolic waste (Mets*min*week-1)\", \"number of work hours/day\" and \"number of obesity antecedents\". In general, prevalence rates for sufficient practice were slightly higher when applying ACSM/AHA criteria in comparison with IPAQ. Kappa statistics indicated satisfactory agreement between these criteria (Kappa?1), in both genders, with crude coefficients kmale=0.95 (CI95% 0.83-1.06) and kfem=0.93 (CI95% 0.85-1.01). Conclusions: The IPAQ and ACSM/AHA criteria showed practically the same ability to classify participants in terms of PA levels. The results indicated high IP prevalence and ST means in the population. The associations found reinforce the need to implement specific Programs of PA promotion and ST decrease, as different sets of factors remained associated with these outcomes. These Programs can contribute to the adoption of a healthy lifestyle and to the prevention of chronic-degenerative diseases in this population.

Entre a casa e a escola : prática de atividades físicas e desenvolvimento infantil

Coelho, Vitor Antonio Cerignoni 23 June 2017 (has links)
Pré-escolares não estão praticando o mínimo de atividade física (AF) segundo diretrizes internacionais, isto tem provocado o aumento do sedentarismo infantil e prejuízos ao desenvolvimento integral. Entre os fatores que podem influenciar a prática de AF, nesta faixa etária, estão as pessoas e os ambientes envolvidos diretamente com as crianças. Assim, o objetivo principal da pesquisa foi verificar o que pais e professores pensam sobre desenvolvimento infantil e como isto se reflete na oferta de atividades físicas para préescolares. Foi realizada uma pesquisa de campo com 438 adultos (197 professores e 241 pais e responsáveis de crianças em idade pré-escolar) provenientes de cinco municípios da região metropolitana de Palmas/TO. Os participantes responderam dois questionários com 35 perguntas sobre o perfil sociodemográfico, atividades realizadas pelas crianças dentro e fora da escola, o que era necessário para a criança se desenvolver e hábitos de AF. Este estudo tem um desenho ecológico e a análise do microssistema mostrou que a frequência diária de AF dentro e fora da escola é baixa (11% e 12%), enquanto que as atividades que facilitam o comportamento sedentário foram oferecidas por 28% e 30% dos professores e pais respectivamente. Quanto aos aspectos necessários para a criança se desenvolver, ambos os grupos priorizaram as necessidades básicas, o acompanhamento familiar e as atividades de leitura, escrita e cálculo. O perfil sociodemográfico dos participantes também influenciou na oferta de atividades físicas (idade, nível de escolaridade e renda). O mesossistema apontou para uma contradição entre a importância e a frequência diária das AF no ambiente escolar e domiciliar e também uma diferença nas respostas indicadas por pais e professores. O exossistema revelou que os hábitos de AF dos pais e professores estavam associados a indicação de oferta de prática para as crianças. O macrossistema identificou que a má qualidade da educação infantil, a falta de AF da população, problemas com formação e capacitação profissional e as crenças dos adultos dificultam a inclusão de prática de atividade física para pré-escolares. Os contextos analisados e a não valorização da AF como um dos aspectos prioritários para o desenvolvimento infantil podem limitar as oportunidades de escolha e dificultar a realização de estratégias que revertam os baixos níveis de AF entre préescolares sendo necessário fomentar a aproximação e o dialogo entre a escola e a família. / Among home and school: practice of physical activity and child development Preschoolers are not practicing the minimum of physical activity (PA) according to international guidelines, it has caused the increase of the infant sedentary lifestyle and damages to the integral development. Among the factors which can influence the practice of PA in this age group are people and environments directly involved with children. Thus, the main objective of this research was verifying what parents and teachers think about child development and what way this reflected in the offer physical activities for preschoolers. A field research was done involving 438 adults (197 teachers and 241 parents and guardians of preschool children) from five counties in the metropolitan region of Palmas, the capital of Tocantins State. The participants have answered two questionnaires with 35 questions were about the socio demographic profile, to the activities performed by the children inside and outside of school, a question about what is need for the child development and another about the PA habits. This study has an ecological design and the analysis of the microsystem has showed that the daily frequency of PA inside and outside of school is low (11% and 12%), whereas the activities which can facilitate sedentary behavior were daily offered by 28% and 30% of teachers and parents, respectively. As to necessary aspects for the child development, both groups prioritized the basic necessities, family accompaniment and activities reading, writing, and calculating. The socio demographic profile of the participants has also influenced the offer of the practice of physical activity (age, level education and income). The mesosystem was verified an contradiction between the importance and the daily frequency of PA in the school and home environment, there was also a difference in the answers indicated, which have revealed a discrepancy between the opinion of the parents and teachers. The exosystem has revealed that the PA habits of parents and teachers were associated with indication of the offer of practice for the children. The macrosystem has identified that the poor quality of early childhood education, the lack of PA of the population, the precariousness of professional training programs and beliefs of adults difficult the inclusion the practice of physical activity for preschoolers. The contexts analyzed and the no valorization of the PA as one of the priorities for child development may limit the opportunities of choice and hamper the realization to strategies which reverse the low levels of PA among preschoolers so it is necessary to foster the rapprochement and dialogue between the school and the family.
