An interventional study of 6-week outdoor strength training program using activity benches and a smartphone application in Exercise Training, sponsored by Universitaire Ziekenhuizen KU Leuven. Recruiting at 1 site in Belgium. Open to participants aged 65 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-11-10.

In order to promote healthy ageing and independent living, the World Health Organization recommends older adults to engage in resistance exercise at least twice weekly. However, only a minority of the older population complies with these guidelines, stressing the urgent need to develop comprehensive strategies to implement resistance exercise programs in the community. This PhD project will be performed in close collaboration with IPitup vzw, who developed outdoor activity benches, an accommodating smartphone app with exercise instructions and training courses as a low-cost modality for resistance exercise in the general population. The aim is to build upon these existing structures and develop an optimized, progressive resistance exercise program for community-dwelling older adults, which can be performed in small groups without the need for specialized training experts. The program's feasibility, defined in terms of safety, adherence, usability and acceptability, will be tested.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Participants take part in a 6-week outdoor strength training program using activity benches and a smartphone application. Training is performed in small groups of six community-dwelling older adults. Within each group, one participant acts as a peer coach and provides practical support and motivation.
Other: 6-week outdoor strength training program using activity benches and a smartphone application
2x/week, 35-45min sessions at the outdoor activity bench
Number of Participants Experiencing Adverse Events
Safety of the intervention, assessed as the number of participants experiencing one or more adverse events related to testing or training sessions during the intervention period.
Time frame: Throughout the 6-week intervention
Participant Adherence Rate
Adherence to the intervention, assessed as the proportion of participants who complete the intervention and post-intervention assessments. And assessed as the percentage of scheduled training sessions attended by participants during the 6-week intervention.
Time frame: Throughout the 10-week study period
System Usability Scale (SUS)
Usability of the intervention will be assessed using the System Usability Scale (SUS), a 10-item questionnaire yielding a total score ranging from 0 to 5. Five items are positively worded, for which higher response scores indicate greater usability, while five items are negatively worded and are reverse-scored, such that lower response scores indicate greater usability.
Time frame: Post-intervention at week 9
Net Promoter Score (NPS)
Acceptability of the intervention, assessed using the Net Promoter Score (NPS), based on participants' likelihood of recommending the programme to others. Scores range from 0 to 10, with higher scores indicating greater acceptability and willingness to recommend the intervention.
Time frame: Post-intervention at week 9
Participant Acceptability of the Intervention
Acceptability of the intervention, assessed through participant feedback regarding the peer-led delivery model and the appropriateness of training intensity and progression. Responses will be summarized descriptively.
Time frame: Post-intervention at week 9
Completion Rate of Data Collection Procedures
Feasibility of data collection procedures, assessed as the proportion of planned laboratory-based assessments, questionnaire assessments, and IPitup app-based assessments successfully completed by participants. Higher percentages indicate greater feasibility of the data collection procedures.
Time frame: Over the 10-week study period
Change in Lower Limb Muscle Strength and Power
Preliminary effects of the intervention on muscle strength and power, assessed as the change in lower limb muscle strength and power from baseline to post-intervention. Muscle strength and power will be measured using the predefined study strength assessment protocol. Higher values indicate greater muscle strength and power.
Time frame: Baseline at week 1 and post-intervention at week 9
Implementation Barriers and Facilitators Identified During Focus Groups
Implementation barriers and facilitators will be explored through semi-structured focus groups conducted following the intervention. Audio recordings will be transcribed verbatim and analysed using qualitative thematic analysis. Identified barriers and facilitators will be categorized into themes to inform optimization of a future randomized controlled trial.
Time frame: Post-intervention at week 10
