Abstract
BACKGROUND: The Lifestyle-integrated Functional Exercise (LiFE) program is an intervention integrating balance and strength activities into daily life, effective at reducing falls in at-risk people ≥70 years. There is potential for LiFE to be adapted to young seniors in order to prevent age-related functional decline.
OBJECTIVE: We aimed to (1) develop an intervention by adapting Lifestyle-integrated Functional Exercise (aLiFE) to be more challenging and suitable for preventing functional decline in young seniors in their 60s and (2) perform an initial feasibility evaluation of the program. Pre-post changes in balance, mobility, and physical activity (PA) were also explored.
METHODS: Based on a conceptual framework, a multidisciplinary expert group developed an initial aLiFE version, including activities for improving strength, neuromotor performances, and PA. Proof-of-concept was evaluated in a 4-week pre-post intervention study measuring (1) feasibility including adherence, frequency of practice, adverse events, acceptability (i.e., perceived helpfulness, adaptability, level of difficulty of single activities), and safety, and (2) changes in balance/mobility (Community Balance and Mobility Scale) and PA (1 week activity monitoring). The program was refined based on the study results.
RESULTS: To test the initial aLiFE version, 31 young seniors were enrolled and 30 completed the study (mean age 66.4 ± 2.7 years, 60% women). Of a maximum possible 16 activities, participants implemented on average 12.1 ± 1.8 activities during the intervention, corresponding to mean adherence of 76%. Implemented activities were practiced 3.6-6.1 days/week and 1.8-7.8 times/day, depending on the activity type. One noninjurious fall occurred during practice, although the participant continued the intervention. The majority found the activities helpful, adaptable to individual lifestyle, appropriately difficult, and safe. CMBS score increased with medium effect size (d = 0.72, p = 0.001). Increase in daily walking time (d = 0.36) and decrease in sedentary time (d = -0.10) were nonsignificant. Refinements included further increasing the task challenge of some strength activities and defining the most preferred activities in the trainer's manual to facilitate uptake of the program.
CONCLUSION: aLiFE has the potential to engage young seniors in regular lifestyle-integrated activities. Effectiveness needs to be evaluated in a randomized controlled trial.

This work was supported by the European Commission’s Horizon-2020 research and innovation program (PreventIT Project, grant number 689238). The content of this paper is solely the responsibility of the authors and does not necessarily represent the official views of the European Commission. aLiFE was developed as part of the PreventIT Project (Horizon 2020, grant no. 689238). PreventIT aims to develop aLiFE (year 1), transfer it to an electronic platform (eLiFE, year 1) and compare both programs in a randomized controlled trial (RCT; year 2–3). This paper reports the development, testing, and refinement of aLiFE. The study protocol relating to eLiFE and the RCT is published separately [14]. We used the UK Medical Research Council (MRC) framework [15] to guide the development and initial feasibility testing of the aLiFE intervention in 2 stages. Stage 1 included the development of the initial aLiFE version based on 5 multidisciplinary workshops involving experts in movement and exercise sciences, physiotherapy, psychology, public health, occupational therapy, gerontology, and geriatric medicine. Six seniors aged between 60 and 70 years (2 males, 4 females) were also involved in the initial development and provided feedback about the ideas of the interdisciplinary team. Stage 2 included feasibility testing of the initial aLiFE version in a pilot study with the target group. Refinements to the program were made based on the study results.
