Background Physical activity (PA) is a fluctuating behavior and prone to change across the life course. Changes in PA may be particularly due to the experience of life events and transitions. For well-timed and successful PA interventions, it is important to understand when and why individuals take up or terminate PA. Objectives This scoping review aims to examine the extent, range, and nature of research on the impact of life events and transitions on PA and to summarize key findings. Methods A systematic literature search was conducted in PubMed, PsycINFO, PsycARTICLES, SPORTDiscus, and Web of Science. Articles were included if they had been published in peer-reviewed journals between 1998 and 2020 and assessed the impact of at least one life event or transition on PA. Results 107 studies that assessed 72 distinct life events and transitions were included and summarized in ten categories. Events and transitions that are primarily associated with decreases in PA were starting cohabitation, getting married, pregnancy, evolving parenthood, and the transitions from kindergarten to primary school, from primary to secondary school, and from high school to college or into the labor market. Retirement was associated with increases in PA; yet, long-term trajectories across retirement indicated a subsequent drop in activity levels. Divorce was associated with no changes in PA. No trends could be identified for changing work conditions, quitting or losing a job, starting a new relationship, widowhood, moving, and diagnosis of illness. Conclusion Life events and transitions can be conceptualized as natural interventions that occur across the life course and that are oftentimes associated with changes in PA behavior. Our study

Objectives: The health-enhancing benefits or regular physical activity (PA) reach into old age. With the emergence of the coronavirus disease of 2019 (COVID-19) pandemic and the associated national lockdowns and restrictions, nursing home residents were restrained from being physically active. In our study, we aimed to assess the impact of the COVID-19-related restrictions on PA promotion in nursing homes from an organizational-sociological lens. Methods: We collected data in eight nursing homes in Germany. Data collection included (i) semistructured interviews focusing on COVID-19-related restrictions and their effects on nursing homes from the home administrators' perspectives; (ii) open-ended surveys with nursing home staff and relatives focusing on daily routines and contact restrictions; and (iii) collection of documents such as care concepts, mission statements, and weekly activity plans. We analyzed all data with a reflexive thematic analysis approach. Results: We identified three stages of COVID-19-related changes in nursing homes that impacted PA promotion, as follows: (1) external closure and search for emergency control, (2) organizational adaptations to create a livable daily life in the internal environment, and (3) slow reintegration of interactions with the external organizational environment. Document analysis revealed that PA promotion was not part of decision programs or internal staff work descriptions. Rather, PA promotion was delegated to external service providers. The assignment of PA promotion to external providers was not structurally anchored in decision programs, which makes PA promotion not sustainable, particularly during unforeseen events that limit access to the organization. During the pandemic, executive staff believed in internal staff to buffer competencies with regard to PA promotion. Thus, executive staff often considered PA promotion relevant, even during the pandemic, but thought that PA promotion is a task that can be fulfilled by unqualified but motivated internal staff. Frahsa et al. COVID-19: PA in Nursing Homes Conclusion: While our study participants showed a high level of coping-capacity belief, it remains unclear which long-term impacts of COVID-19 on PA promotion in nursing homes are to be expected. At the practice level, executive staff in nursing homes that aim to promote PA within their organization should become aware that PA promotion needs to be incorporated into organizational structures to be implemented and continued in challenging times such as in a pandemic.

BackgroundPhysical activity is a substantial promoter for health and well-being. Yet, while an increasing number of studies shows that the responsiveness to physical activity is highly individual, most studies focus this issue from only one perspective and neglect other contributing aspects. In reference to a biopsychosocial framework, the goal of our study is to examine how physically inactive individuals respond to two distinct standardized endurance trainings on various levels. Based on an assessment of activity- and health-related biographical experiences across the life course, our mixed-method study analyzes the responsiveness to physical activity in the form of a transdisciplinary approach, considering physiological, epigenetic, motivational, affective, and body image-related aspects.MethodsParticipants are randomly assigned to two different training programs (High Intensity Interval Training vs. Moderate Intensity Continuous Training) for six weeks. After this first training period, participants switch training modes according to a two-period sequential-training-intervention (STI) design and train for another six weeks. In order to analyse baseline characteristics as well as acute and adaptive biopsychosocial responses, three extensive mixed-methods diagnostic blocks take place at the beginning (t0) of the study and after the first (t1) and the second (t2) training period resulting in a net follow-up time of 15 weeks. The study is divided into five modules in order to cover a wide array of perspectives.DiscussionThe study's transdisciplinary mixed-method design allows to interlace a multitude of subjective and objective data and therefore to draw an integrated picture of the biopsychosocial efficacy of two distinct physical activity programs. The results of our study can be expected to contribute to the development and design of individualised training programs for the promotion of physical activity.Trial registrationThe study was retrospectively registered in the German Clinical Trials Register on 12 June 2019 (DRKS00017446).
