Aging is associated with decreased muscle mass and functional capacity, which in turn decrease quality of life. The number of citizens over the age of 65 years in the Western world will increase by 50 % over the next four decades, and this demographic shift brings forth new challenges at both societal and individual levels. Only a few longitudinal studies have been reported, but whey protein supplementation seems to improve muscle mass and function, and its combination with heavy strength training appears even more effective. However, heavy resistance training may reduce adherence to training, thereby attenuating the overall benefits of training. We hypothesize that light load resistance training is more efficient when both adherence and physical improvement are considered longitudinally. We launched the interdisciplinary project on Counteracting Age-related Loss of Skeletal Muscle Mass (CALM) to investigate the impact of lifestyle changes on physical and functional outcomes as well as everyday practices and habits in a qualitative context. We will randomize 205 participants older than 65 years to be given 1 year of two daily nutrient supplements with 10 g of sucrose and 20 g of either collagen protein, carbohydrates, or whey. Further, two groups will perform either heavy progressive resistance training or light load training on top of the whey supplement. The primary outcome of the CALM Intervention Study is the change in thigh cross-sectional area. Moreover, we will evaluate changes in physical performance, muscle fiber type and acute anabolic response to whey protein ingestion, sensory adaptation, gut microbiome, and a range of other measures, combined with questionnaires on life quality and qualitative interviews with selected subjects. The CALM Intervention Study will generate scientific evidence and recommendations to counteract age-related loss of skeletal muscle mass in elderly individuals. ClinicalTrials.gov NCT02034760 .

Many older people live with a range of chronic diseases. However, these diseases do not necessarily impede an active lifestyle. In this article the author analyses the relation between the active ageing discourse and the way older people at two Danish activity centres handle disease. How does active ageing change everyday life with chronic disease, and how do older people combine an active life with a range of chronic diseases? The participants in the study use activities to keep their diseases at arm's length, and this distancing of disease at the same time enables them to engage in social and physical activities at the activity centre. In this way, keeping disease at arm's length is analysed as an ambiguous health strategy. The article shows the importance of looking into how active ageing is practised, as active ageing seems to work well in the everyday life of the older people by not giving emphasis to disease. The article is based on ethnographic fieldwork and uses vignettes of four participants to show how they each keep diseases at arm's length.

In recent decades, the extension of individuals’ working life has been construed as an important policy issue in Western Europe. Here, retirement causes have been thoroughly researched in a quantitative way, but there is a dearth of qualitative studies on the subject. Through ethnographic fieldwork, we study the complex pathways that lead to the retirement of senior employees in the finance and production industries in Denmark. In particular in the finance industry, we find an insidious uncertainty haunting senior employees regarding their capacity and reputation. We term this uncertainty worn-out syndrome, demonstrating how many interlocutors fear that they are beginning to be seen as worn out, for example, less productive, less motivated, and too old to work. To some extent, this syndrome resembles the impostor syndrome, but it differs in one important aspect: the senior employees are mostly confident about their own skills. Worn-out syndrome is triggered by stereotypes and implicit ageist remarks by colleagues and managers. We show that the worn-out syndrome appears in at least three different ways: as a fear of already being worn out, as a fear of being perceived as worn out by colleagues and managers, and as a fear of becoming worn out in the future without realizing it in time. We argue that current retirement decisions are often fueled by this syndrome and that it leads to abrupt and untimely retirement decisions.

There is growing interest, within the social sciences, in understanding self‐quantification and how it affects health practices in contemporary society. There is, however, less research on how ageing and health measurement relate, even though this relationship has become more pertinent with the growing availability of services and devices offering biological, personalised age measurements, from simple online questionnaires to telomere length quantification. Little is known about who uses these devices, why they use them and the socio‐technical implications of such uses. To explore these issues, we conducted semi‐structured interviews and focus groups with users of measurements of biological age (BA) in Denmark. We found that participants engage with the measurements with a degree of scepticism regarding their technical validity, reliability and sensitivity. Rather than seeking an exact biological quantification, participants use measurements as a pragmatic, rough indication of individual health. We develop a conceptual model to understand participants’ engagement with BA measurements, which suggests that, instead of a substitution of chronological age for BA, users gauge the difference between the two to qualify their present and future individual trajectory in a lay model of the relationship between functional capacity and age.
