Acceptability of a Portable Exercise Bike in Older Adults With Cardiovascular Diseases.

Background: Ways to help older adults overcome barriers to performing regular exercise is a challenge to nurses.

Objective: The study evaluated the acceptability of a portable exercise bike for arm/foot pedaling among older patients with cardiovascular diseases (CVDs).

Methods: Participants reported their physical activity levels using the International Physical Activity Questionnaire (short form) and thereafter performed two 6-minute-long arm/foot pedal biking sessions using a portable exercise bike. Participants provided qualitative feedback (one open-ended question) on the bike while exercising and completed the quantitative Acceptability Use Questionnaire following the two exercise sessions.

Results: Twenty-five older adults (52% male and 48% female), with a mean (SD) age of 70 (6.4) years and a body mass index of 30 (7.4), completed the study. Most participants performed moderate to light physical activity at home with a daily mean (SD) sitting/sedentary time of 8 (3.4) hours. The mean scores from the Acceptability Use Questionnaire and the participants' comments alluded to the bike's multitasking utility and acceptability. Three broad themes derived from the qualitative analysis were: (1) the acceptability of the bike with participants who had musculoskeletal problems; (2) the ability to operate and use the bike for aerobic exercise engaging both arms and legs; and (3) the importance of overall utility, ease of use, and cost of the bike.

Conclusions: The portable exercise bike was found acceptable in a group of older adults with CVDs. The bike has the potential to be applied in home-based exercise interventions.
