Childcare workers are reported to have high variation in physical activity during work hours, but also to sit for about half of the workday and have almost no high intensity physical activity (HIPA). No study has investigated if their work can be re-designed to introduce HIPA, thus promoting fitness and health according to the Goldilocks principle. This study investigated the feasibility of designing pedagogical games (‘Goldilocks-games’) intended to lead to more HIPA. Heart rate was measured in nineteen childcare workers during Goldilocks-games, and compared to measurements during a regular workday. Worker perceptions of feasibility, and researcher observations of contextual factors were also collected. The Goldilocks-games (33 min) elicited significantly more HIPA (18/33 min) compared to the most active period of equal length on a regular workday (0.5/33 min). Seventy-four-percent of the childcare workers reported that it was feasible to integrate the Goldilocks-games pedagogically, and seventy-two-percent could see themselves using them. Thus, we found it possible to re-design a work task in childcare according to the Goldilocks principle so that it leads to substantial time with HIPA. The sustainability of Goldilocks-games in childcare, and their effectiveness in improving fitness and health among childcare workers, needs to be tested in further studies.

Background: There is increasing recognition of the need for more comprehensive surveillance data, including information on physical activity of all intensities, sedentary behavior, and sleep. However, meeting this need poses significant challenges for current surveillance systems, which are mainly reliant on self-report. Objective: The primary objective of this project is to develop and evaluate the feasibility of a sensor-based system for use in the surveillance of physical activity, sedentary behavior, and sleep (SurPASS) at a national level in Denmark. Methods: The SurPASS project involves an international, multidisciplinary team of researchers collaborating with an industrial partner. The SurPASS system consists of (1) a thigh-worn accelerometer with Bluetooth connectivity, (2) a smartphone app, (3) an integrated back end, facilitating the automated upload, analysis, storage, and provision of individualized feedback in a manner compliant with European Union regulations on data privacy, and (4) an administrator web interface (web application) to monitor progress. The system development and evaluation will be performed in 3 phases. These phases will include gathering user input and specifications (phase 1), the iterative development, evaluation, and refinement of the system (phase 2), and the feasibility evaluation (phase 3). Results: The project started in September 2020 and completed phase 2 in February 2022. Phase 3 began in March 2022 and results will be made available in 2023. Conclusions: If feasible, the SurPASS system could be a catalyst toward large-scale, sensor-based surveillance of physical activity, sedentary behavior, and sleep. It could also be adapted for cohort and interventional research, thus contributing to the generation of evidence for both interventions and public health policies and recommendations.

Carpenters in construction commonly perform overhead work tasks such as installing ceiling panels, plastering, and formwork. While laboratory studies suggest exoskeletons may reduce strain during such work, their effectiveness in real-life conditions remains uncertain. This randomized cross-over field study investigates the effects of a passive shoulder exoskeleton on muscle activity and kinematics in 20 carpenters during overhead work tasks. Results showed reduced peak muscle activity (nEMG) in the shoulders and forearms (-3.1 to -9.4 %), but increased activity in the lower back (2.3-3.4 %) when using the exoskeleton. Kinematic analysis revealed minimal changes in range-of-motion (<3.1°) and peak joint angles. Participants reported good usability and willingness to use the exoskeleton in the future. This study demonstrates positive effects on shoulder load in real working conditions but highlights the need to consider increased low-back load when implementing exoskeletons for overhead work.

Exercise is a cornerstone in diabetes care; however, adherence is low and sustaining physical activity remains a challenge. Patient-centered diabetes self-management education and support are recommended; however, sparse literature exists on how to design exercise interventions that improve self-management in individuals with complications of type 2 diabetes mellitus (T2D). We aimed to gain insights into needs, barriers, and motivation based on experiences with exercise participation among individuals with T2D and complications to adjust and develop new types of tailored, supervised exercise classes in specialized care at three hospitals in Denmark. In keeping with a constructivist research paradigm, a qualitative hermeneutic approach using focus group interviews was applied to explore perspectives among different participants in terms of disease severity. Seven interviews with 30 participants (aged 49–88) representing seven different exercise classes, were conducted over three years. Reflective thematic analysis was used. Four themes were generated: People like us, Getting started with exercise, Game changers, and Moving forward. An overarching theme ‘The transformation of motivation when exercising in a safe and kind environment’ links the themes together, resembling the participants’ development of physical literacy encompassing motivation, confidence, physical competence as well as an ability to value physical activity. Supportive patient-centered exercise classes promoted a transformation of motivation grounded in the development of physical literacy among participants in specialized diabetes care. However, participants were concerned with continuing to exercise on their own after the intervention, as they experienced a lack of continuous, supervised exercise opportunities in local communities.

Background: Device-based measurements of physical behavior, using the current methods, place a large burden on participants. The Motus system could reduce this burden by removing the necessity for in-person meetings, replacing diaries written on paper with digital diaries, and increasing the automation of feedback generation. Objective: This study aims to describe the development of the Motus system and evaluate its potential to reduce participant burden in a two-phase usability evaluation. Methods: Motus was developed around (1) a thigh-worn accelerometer with Bluetooth data transfer; (2) a smartphone app containing an attachment guide, a digital diary, and facilitating automated data transfer; (3) a cloud infrastructure for data storage; (4) an analysis software to generate feedback for participants; and (5) a web-based app for administrators. We recruited 19 adults with a mean age of 45 (SD 11; range 27-63) years, of which 11 were female, to assist in the two-phase evaluation of Motus. A total of 7 participants evaluated the usability of mockups for a smartphone app in phase 1. Participants interacted with the app while thinking aloud, and any issues raised were classified as critical, serious, or minor by observers. This information was used to create an improved and functional smartphone app for evaluation in phase 2. A total of 12 participants completed a 7-day free-living measurement with Motus in phase 2. On day 1, participants attempted 20 system-related tasks under observation, including registration on the study web page, reading the information letter, downloading and navigating the smartphone app, attaching an accelerometer on the thigh, and completing a diary entry for both work and sleep hours. Task completion success and any issues encountered were noted by the observer. On completion of the 7-day measurement, participants provided a rating from 0 to 100 on the System Usability Scale and participated in a semistructured interview aimed at understanding their experience in more detail. Results: The task completion rate for the 20 tasks was 100% for 13 tasks, >80% for 4 tasks, and <50% for 3 tasks. The average rating of system usability was 86 on a 0-100 scale. Thematic analysis indicated that participants perceived the system as easy to use and remember, and subjectively pleasing overall. Participants with shift work reported difficulty with entering sleep hours, and 66% (8/12) of the participants experienced slow data transfer between the app and the cloud infrastructure. Finally, a few participants desired a greater degree of detail in the generated feedback. Conclusions: Our two-phase usability evaluation indicated that the overall usability of the Motus system is high in free-living. Issues around the system’s slow data transfer, participants with atypical work shifts, and the degree of automation and detail of generated feedback should be addressed in future iterations of the Motus system.

Background: Eldercare workers in nursing homes report high musculoskeletal disorders, stressful work, and sickness absence. Initiatives that can accommodate these issues are needed. Current studies point out that nature contact may offer a range of human health benefits, potentially promoting healthier work among eldercare workers. Therefore, this study aimed to investigate facilitators and barriers for using outdoor areas as part of the daily work among eldercare workers in Danish nursing homes. Methods: In this multiple case study, we collected data from three nursing homes, conducting three semi-structured focus group interviews with eldercare workers and three individual interviews with nursing home managers. Furthermore, we conducted observations of the daily work and mappings of the nursing homes’ outdoor environments to gain in-depth knowledge of eldercare workers’ and managers’ perspectives on using outdoor areas in their daily work. The data was thematically analysed using ‘The Behaviour Change Wheel’ (BCW), more specifically the COM-B model, as a theoretical foundation for exploring facilitators and barriers for the use of outdoor areas. Results: Frequently mentioned facilitators were facilities, traditions or repetitive events, positive experiences with residents (‘star moments’), and knowledge about the residents. Frequently mentioned barriers were insufficient staffing, hierarchy in the work tasks, professional identity, and lack of ideas. Conclusions: The identified facilitators and barriers should be considered when designing initiatives for increased use of outdoor areas or activities of eldercare workers. Trial registration: According to the Danish ethics committee (Law of committee, (komitéloven) paragraph 14, Sect. 2), qualitative interviews, which do not include human biological materials, do not need neither approval by ethical and scientific committee or informed consent (The Danish National Centre for Ethics).
