    This paper will first provide background information about Virtual Reality in order to better analyze its development throughout history and into the future. Next, this essay begins an in-depth historical analysis of how virtual reality has developed prior to 1970, a pivotal year in Virtual Reality history, followed by an exploration of how this development paradigm shifted between the 1970\u27s and the turn of the century. The historical analysis of virtual reality is concluded by covering the modern period from 2000-present. Finally, this paper examines the layout of the virtual reality field in respect to he history and innovations presented

    Interventions for reducing sedentary behaviour in community-dwelling older adults

    This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To identify the effects and assess the effectiveness of interventions to reduce sedentary behaviour (total sedentary time and the pattern of accumulation of sedentary time) in older adults. To summarise the effects of interventions to reduce sedentary behaviour on quality of life, depression, and health status in older adults. To summarise any evidence on the cost-effectiveness of interventions that reduce sedentary behaviour in older adults

    Determinants of sedentary behavior, motivation, barriers and strategies to reduce sitting time in older women: a qualitative investigation

    Abstract: Sedentary behavior defined as time spent non-exercising seated or reclining posture has been identified has a health risk and associated with frailty and disablement for older adults. Older adults are the most sedentary segment of society. To date no study has investigated the determinants of sedentary behavior in older adults. This study reports a qualitative investigation of the determinants of sedentary behavior, strategies and motivator to reduce sitting time by structured interviews in a group of community dwelling older women (N = 11, age 65 and over). Older women expressed the view that their sedentary behavior is mostly determined by pain which acts both as an incentive to sit and a motivator to stand up, lack of energy in the afternoon, pressure from direct social circle to sit and rest, societal and environmental typecasting that older adult are meant to sit, lack of environmental facilities to allow activity pacing. This qualitative investigation highlighted some factors that older adults consider determinants of their sedentary behavior. Some are identical to those affecting physical activity (self-efficacy, functional limitations, ageist stereotyping) but some appear specific to sedentary behavior (locus of control, pain) and should be further investigated and considered during intervention design.

    What happened to my legs when I broke my arm?

    This case report describes an incident that occurred during the course of a research intervention study. Participants in the study were continually monitored with an activPAL activity monitor. Whilst wearing the monitor a participant had a fall causing musculoskeletal trauma requiring hospital admission. The patient was admitted for an acute hospital stay (3 days) for management of the upper limb injury. The case report presents the measurement of the participant’s sedentary time before the incident, during hospitalisation and post discharge. The report is relevant for education and service design both in hospital and in the community settings as it demonstrates the rapid influence of an upper limb injury and consequences beyond the hospital bed. This report is novel as it presents not only hospitalisation and post hospital activity, but also provides insight into the individual’s actual objective (rather than retrospective self-report) activity patterns before hospitalisation. The infographic presentation has been chosen to allow quick and easy understanding of information

    Consequences of short interruptions of bouts walking on estimates of compliance to physical activity guidelines

    Current guidelines on physical activity suggest that 30 min of moderate intensity physical activity can be accumulated in continuous bouts of at least 10 min. It has been shown by use of activity monitoring that it is difficult to achieve 10 min of completely uninterrupted walking in the free-living urban environment where we have obstacles such as roads to cross. The aim of this study was to examine the effect of short interruptions in walking on the rate of oxygen uptake (ml . kg . min(-1)) to determine if walking with short interruptions can still be considered continuous. This leads to a more meaningful understanding as to what is a physiological break in activity. This is an important consideration for measurement of physical activity especially when exploring measurement by accelerometry. In a laboratory setting a repeated measure design was used to replicate interrupted walking in urban setting. Healthy volunteers (N = 10) walked on a treadmill with walking interruptions of 10 s, 50 s and 100 s. Oxygen uptake was measured using a gas analysis system. 10 s interruptions in walking had no significant effect on the VO2 . kg . min(-1). However two breaks of 50 s or 100 s introduced into a 5 min brisk walking bout showed a significant reduction in oxygen uptake requirements and metabolic equivalent of task (MET) (p < 0.001) compared to continuous walking for the same amount of effective walking, but only the 100 s walking period could not be considered greater than 3 MET during the interval. Short periods of brisk walking interrupted by 10 s breaks can be considered continuous physical activity, but when walking is interrupted by longer breaks e.g. 50 s, there is a significant reduction in oxygen uptake requirement suggesting that it is not continuous anymore and should be considered as fragmented

    Co-creating a tailored public health intervention to reduce older adults’ sedentary behaviour

    Objective: The increasing health care costs associated with an ageing population and chronic disease burden are largely attributable to modifiable lifestyle factors that are complex and vary between individuals and settings. Traditional approaches to promoting healthy lifestyles have so far had limited success. Recently, co-creating public health interventions with end-users has been advocated to provide more effective and sustainable solutions. The aim of this study was to document and evaluate the co-creation of a public health intervention to reduce sedentary behaviour in older adults. Design: Community-dwelling older adults (N = 11, mean age = 74 years) and academic researchers attended 10 interactive co-creation workshops together. Setting: Workshops took place on university campus and the co-creators completed fieldwork tasks outside the workshops. Method: Workshops were informed by the Participatory and Appreciative Action and Reflection methodology. Data were collected using field notes, video recording and worksheet tasks. Analysis was conducted using a qualitative content analysis approach. Results: The co-creators developed a tailored intervention delivered through a mode congruent with older adults' lives. Key elements of the intervention included (1) education on sedentary behaviour, (2) resources to interrupt sedentary behaviour, (3) self-monitoring, (4) action planning and (5) evaluating the benefits of interrupting sedentary behaviour. Conclusion: Co-creation is a feasible approach to develop public health interventions; however, it is limited by the lack of a systematic framework to guide the process. Future work should aim to develop principles and recommendations to ensure co-creation can be conducted in a more scientific and reproducible way. The effectiveness and scalability of the intervention should be assessed
