In this article I explore a perspective that the philosophical concepts of German phenomenologist Hermann Schmitz (*1928) may open up for thinking about the growing practice of wearing textile integrated electronics directly on the body. It is my contention that traditional conceptions of wearing (non-technological) clothing on the body fail to capture the changed situation and I hence suggest a paradigm shift is needed to think about the novel scope of affects that can be related to body-technology communication. Schmitz’s concepts of the perceptive felt body, corporeal communication and emotions as atmospheres perceived as outside, on or close to the ‘material’ body will be elaborated upon to investigate how they may enhance existing notions of bodily perception and human-technology relations. The case study used for this philosophical investigation is found in the Tactile Sleeve for Social Touch, a wearable created by Elitac, HvA and UTwente, which allows sensations of stroking, tapping and touching to be communicated from one person to another across a distance.

The retirement phase is an opportunity to integrate healthy (nutrition/exercise) habits into daily life. We conducted this systematic review to assess which nutrition and exercise interventions most effectively improve body composition (fat/muscle mass), body mass index (BMI), and waist circumference (WC) in persons with obesity/overweight near retirement age (ages 55–70 y). We conducted a systematic review and network meta-analysis (NMA) of randomized controlled trials, searching 4 databases from their inception up to July 12, 2022. The NMA was based on a random effects model, pooled mean differences, standardized mean differences, their 95% confidence intervals, and correlations with multi-arm studies. Subgroup and sensitivity analyses were also conducted. Ninety-two studies were included, 66 of which with 4957 participants could be used for the NMA. Identified interventions were clustered into 12 groups: no intervention, energy restriction (i.e., 500–1000 kcal), energy restriction plus high-protein intake (1.1–1.7 g/kg/body weight), intermittent fasting, mixed exercise (aerobic and resistance), resistance training, aerobic training, high protein plus resistance training, energy restriction plus high protein plus exercise, energy restriction plus resistance training, energy restriction plus aerobic training, and energy restriction plus mixed exercise. Intervention durations ranged from 8 wk to 6 mo. Body fat was reduced with energy restriction plus any exercise or plus high-protein intake. Energy restriction alone was less effective and tended to decrease muscle mass. Muscle mass was only significantly increased with mixed exercise. All other interventions including exercise effectively preserved muscle mass. A BMI and/or WC decrease was achieved with all interventions except aerobic training/resistance training alone or resistance training plus high protein. Overall, the most effective strategy for nearly all outcomes was combining energy restriction with resistance training or mixed exercise and high protein. Health care professionals involved in the management of persons with obesity need to be aware that an energy-restricted diet alone may contribute to sarcopenic obesity in persons near retirement age.This network meta-analysis is registered at https://www.crd.york.ac.uk/prospero/ as CRD42021276465.

BACKGROUND: Anthropometric measurements are widely used to reliably quantify body composition and to estimate risks of overweight in healthy subjects and in patients. However, information about the reliability of anthropometric measurements in subjects with severe intellectual and sensory disabilities is lacking.OBJECTIVE: The purpose of this study was to determine the feasibility and the test-retest reliability of body composition measures in subjects with severe intellectual and sensory disabilities.METHOD: The study population consisted of 45 subjects with severe intellectual and sensory disabilities. Body mass index, waist circumference, skin folds and tibia length were measured. Reliability was assessed by Wilcoxon signed rank test, limits of agreement (LOA) and intraclass correlation coefficients. The outcomes were compared with values provided by the World Health Organization.RESULTS: There were no significant differences between test and retest (P < 0.05). For the skinfold measurements, however, the LOA was insufficient. Intraclass correlation coefficients for all variables, except skinfold measurements, were 0.90 or above.CONCLUSION: Test-retest reliability and feasibility for all measurements are acceptable in subjects with severe intellectual and sensory disabilities. Skinfold measurements, however, could not be reliably performed in these subjects. Measuring tibia length and using the determined formula to calculate body height from tibia length is a reliable alternative for measuring body height. Although measuring the body height of subjects with severe disabilities was feasible, measuring tibia length was more feasible.
Along with the rapidly growing number of disabled people participating in competitive sports, there is an increased need for (para)medical support in disability sports. Disabled athletes experience differences in body composition, metabolism, training load and habitual activity patterns compared with non-disabled athletes. Moreover, it has been suggested that the well-recognized athlete triad, and low energy availability and low bone mineral density in particular, is even a greater challenge in disabled athletes. Therefore, it is not surprising that sport nutritionists of disabled athletes have expressed an urgency for increased knowledge and insights on the nutritional demands of this group. This project aims to investigate energy expenditure, dietary intake, body composition and bone health of disabled athletes, ultimately leading to nutritional guidelines that promote health and optimal sports performance for this unique population. For this purpose, we will conduct a series of studies and implementation activities that are inter-related and build on the latest insights from sports practice, technology and science. Our international consortium is highly qualified to achieve this goal. It consists of knowledge institutes including world-leading experts in sport and nutrition research, complemented with practical insights from nutritionists working with disabled athletes and the involvement of athletes and teams through the Dutch and Norwegian Olympic committees. The international collaboration, which is a clear strength of this project, is not only focused on research, but also on the optimization of professional practice and educational activities. In this regard, the outcomes of this project will be directly available for practical use by the (para)medical staff working with disabled athletes, and will be extensively communicated to sport teams to ensure that the new insights are directly embedded into daily practice. The project outcomes will also be incorporated in educational activities for dietetics and sport and exercise students, thereby increasing knowledge of future practitioners.
