Background: Maintaining a physically active lifestyle across the life course can add to an individual's health and well-being. Many people are insufficiently active to achieve these gains with a trend towards further decreases in activity as people age. Community-based group exercise programmes have been shown to be one means of increasing sustained activity levels for older people., Aim: To understand how and why older people sustain participation to community-based group exercise programmes from a humanising perspective., Methods: A multiple-case study approach was employed to study three exercise programmes in the South-West of England. Data were collected through participant observation, focus groups and documentation. Data were analysed with deductive thematic analysis and mapped against the humanisation framework., Results: Findings suggest that the humanising nature of these particular exercise programmes supported sustained participation. In these programmes, agency was evidenced in the way participants self-selected their level of exertion with exercises. There was freedom to be their unique selves and exercise within the limits of their insider challenges of an ageing body. Through this non-judgemental exercise environment, there was an embodied understanding of who they were as people. The exercise programme became part of their personal journey. This journey helped inform their future by enabling them to keep active and maintain independence, allowing them to continue engaging in the world. There was a sense of togetherness and belonging which led to feelings of homeliness as they found a sense of place within the group. The friendships they formed helped them make sense and add meaning to their experiences and personal health challenges., Conclusions: When planning exercise environments to support the long-term adoption of a sustained behaviour change, in the form of physical activity for older people, it is helpful to consider dimensions that make an individual feel human., (© 2021 Nordic College of Caring Science.)

Background: Previous evidence has demonstrated that serum leptin is correlated with appetite in combination with, but not without, modest exercise., Aim: The present experiments investigated the effects of exogenous adrenaline and α/β adrenoceptor blockade in combination with moderate exercise on serum leptin concentrations, appetite/satiety sensations and subsequent food intake in obese women., Methods: A total of 10 obese women ((mean ± SEM), age: 50 (1.9) years, body mass index 36 (4.1) kg/m 2 , waist 104.8 (4.1) cm) participated in two separate, double-blind randomised experimental trials. Experiment 1: moderate exercise after α/β adrenergic blocker (labetalol, 100 mg orally) versus moderate exercise plus placebo; experiment 2: adrenaline infusion for 20 minutes versus saline infusion. Appetite/satiety and biochemistry were measured at baseline, pre- and immediately post-intervention, then 1 hour post-intervention (i.e., before dinner). Food intake was assessed via ad libitum buffet-style dinner., Results: No differences were found in appetite/satiety, subsequent food intake or serum leptin in any of the studies (experiment 1 or experiment 2). In experiment 1, blood glucose was higher ( p < 0.01) and plasma free fatty acids lower ( p = 0.04) versus placebo. In experiment 2, plasma free fatty acids ( p < 0.05) increased after adrenaline versus saline infusion., Conclusions: Neither inhibition of exercise-induced adrenergic activity by combined α/β adrenergic blockade nor moderate increases in adrenergic activity induced by intravenous adrenaline infusion affected acute appetite regulation.

There is a complex interplay between cognition and gait in older people, with declines in gait speed coexisting with, or preceding cognitive decline. Omega-3 fatty acids, B vitamins, vitamin E, phosphatidylserine, and Ginkgo Biloba show promise in preserving mobility and cognitive function in older adults. Exercise benefits mobility and there is evidence suggesting positive interactions between exercise and omega-3 fatty acids on physical and cognitive function in older adults. Non-frail or pre-frail females aged ≥60 years are included in a randomized placebo controlled study. Intervention groups are: high DHA multi-nutrient supplement and exercise, placebo supplement and exercise, high DHA multi-nutrient supplement, and placebo supplement. Dietary supplementation is 24 weeks. The exercise intervention, two cycle ergometer classes per week, is for the final 12 weeks. The primary outcome is habitual walking speed, secondary outcomes include gait variables under single and dual task, five times sit to stand, verbal and spatial memory, executive function, interference control and health related quality of life. Blood fatty acids, serum homocysteine, dietary intake, physical activity, and verbal intelligence are measured to assess compliance and control for confounding factors. The study is registered at www.clinicaltrials.gov (NCT03228550)., (Copyright © 2019. Published by Elsevier Ltd.)

Background: Physical inactivity is a global phenomenon, with estimates of one in four adults not being active enough to achieve health benefits, thus heightening the risk of developing non-communicable diseases. In order to realise the health and wellbeing gains associated with physical activity the behaviour must be sustained. Community-based group exercise programmes (CBGEP) utilising social supports have been shown to be one means of not only increasing activity levels for older people, but sustaining physical activity. A gap in the literature was identified around older people's long-term adherence to real-life CBGEP within a UK context. This study therefore sought to address this gap by understanding older people's ongoing adherence to CBGEP with a view to gaining further insight about which factors contribute to enabling people to sustain their physical activity levels., Methods: A multiple case study research design was employed to understand older people's (≥60 years, n = 27) adherence (≥ 69%, for ≥ 1 year) to three current CBGEP in the South- West of England. Qualitative data (participant observation, focus groups, documents, and interviews) were collected and analysed using inductive thematic analysis followed by the analytic technique of explanation building. Quantitative data were analysed using descriptive statistics and used to set the context of the study., Results: The current study offers five unique insights into real-life programmes which have been successful in helping older people maintain adherence for a year or longer. These included: factors relating to the individual, the instructor (particularly their personality, professionalism and humanised approach), programme design (including location, affordability, the use of music, and adaptable exercise content), social features which supported a sense of belonging, and participant perceived benefits (physical and psycho-social). These all served to explain older people's adherence to CBGEP., Conclusions: These factors related to participant adherence of CBGEP must be considered if we wish to support older people in sustaining a physically active lifestyle as they age. These findings are of interest to practitioners and policy makers in how CBGEP serve to aid older people in maintaining a physically active lifestyle with a view to preventing non-communicable diseases and in maintaining social connectivity.
