Intervention
ADVERSE EVENTS, MINOR, EVENT
The exercise snacking intervention consisted of five exercises, each performed for one minute interspersed with one minute of seated rest, with the aim being to complete as many repetitions as possible of each exercise in the given minute. The total length of each exercise ‘snack’ was therefore nine minutes. Participants were instructed to complete the exercises twice a day at home, and only to perform exercise snacks when there was someone else present in the home with capacity to call for help in the event of an emergency. The exercises were sit-to-stand from a chair, seated lateral arm raising to overhead, marching on the spot with high knees (aiming for thigh parallel to the floor), seated arm crossing from arms down by the sides to touching opposite shoulders, and seated calf raises. Participants were provided with a set of written and pictorial instructions on how to complete the exercises along with a logbook in which to record the number of sit-to-stand repetitions completed in each exercise snack, along with a rating of perceived exertion (1–10 scale) for the whole exercise snack. The logbook included space to record minor adverse events or notes from the participant, and clear instruction for reporting serious adverse events to study staff. This logbook was to be returned following the intervention to assess intervention adherence. See Additional file
