Brief summary
This 4-week pilot study aimed to determine the feasibility and acceptability of performing a pragmatic resistance ‘exercise snacking’ program performed once, twice, or thrice daily in community-dwelling older adults when delivered and monitored remotely. Secondary aims were to: 1) explore the dose-response effects of ‘exercise snacking’ on physical function, 2) determine the feasibility of conducting physical function assessments remotely within the homes of participants using videoconferencing, and 3) explore the participants experience and perceptions of the ‘exercise snacking’ approach. It was hypothesised that the exercise program would be feasible (mean of 80% of prescribed sessions completed) for all daily exercise frequencies and it would also be feasible to perform the physical function assessments remotely using videoconferencing.
Interventions
Participants completed home-based resistance ‘exercise snacking’ sessions either once, twice, or thrice daily for four weeks (i.e., the once-daily, twice-daily, and thrice-daily groups). Over four weeks, participants were therefore prescribed a total of 28, 56, or 84 resistance 'exercise snacking' sessions (for the once-daily, twice-daily, and thrice-daily groups, respectively).

Participants completed home-based resistance ‘exercise snacking’ sessions either once, twice, or thrice daily for four weeks (i.e., the once-daily, twice-daily, and thrice-daily groups). Over four weeks, participants were therefore prescribed a total of 28, 56, or 84 resistance 'exercise snacking' sessions (for the once-daily, twice-daily, and thrice-daily groups, respectively). Each resistance ‘exercise snacking’ session consisted of five exercises, with each exercise performed continuously for one minute, with one minute of passive recovery between each exercise (i.e., total time commitment of nine minutes per session). The exercise intervention was remotely delivered (by a member of the research term with expertise in exercise science and physiology) via a commercially available, web-based exercise programming application (PhysiTrackTM) and accompanying end-user application (PhysiAppTM) accessible to participants via a computer, smart phone, or tablet. For this pilot study, PhysiTrackTM and PhysiAppTM were used only for the purposes of delivering the exercise program to participants, including both written instructions and video demonstrations of how to complete each exercise in the program. Immediately after completing each resistance ‘exercise snacking’ session, participants recorded in an exercise diary whether they successfully completed the session (yes or no), their RPE (Rating of Perceived Exertion) using the CR-10 (category ratio 10) scale, and whether any adverse events were experienced. Participant retention was recorded as the number (proportion) of participants who were randomised and completed both the four-week exercise intervention (or control period) and follow-up assessments. Adherence to the exercise intervention was considered as the number of sessions completed as a proportion of the number of planned (prescribed) sessions, which was self-reported by participants via an exercise diary. In addition, exercise adherence was also reported as the prescribed versus actual (completed) based on the following: i) number of days exercised per week, ii) total number (frequency) of ‘exercise snacks’ per week, and iii) total number of ‘exercise snacks’ during the four-week intervention. The exercise intervention was considered feasible if participant retention was at least 90%, and if participants completed a mean of 80% of prescribed sessions.
