Purpose:
To determine the acceptability of 12-weeks of a home-based high-intensity functional strength training (HIFST) intervention to older adult participants (≥ 55 years) with preclinical mobility limitations following a slip, trip, or fall.
Materials And Methods:
A qualitative description study was conducted following a pilot randomized controlled trial of HIFST. HIFST was delivered virtually by a physiotherapist and utilized an interval format (alternating periods of "hard" effort of strengthening exercises with "easy" recovery). Participants randomized to the HIFST intervention were invited to participate in semi-structured interviews and an anonymous survey following intervention completion.
Results:
Eleven participants (of 12 randomized to HIFST) completed interviews and 8 survey responses were received. Our findings were organized into six themes; "overall impression," "intervention coherence," "facilitators," "challenges and future suggestions," "perceived effectiveness," and "sustainability." Participants reported that the program was efficient, met their expectations and "made sense." Various facilitators to participation were noted including support from the physiotherapist and preference for a shorter interval length. Virtual delivery and intensity were not participation barriers. Participants reported benefits and clear individualized plans for future exercise.
Conclusions:
A home-based HIFST intervention delivered virtually was acceptable to participants. Participants reported a positive experience and minimal challenges encountered.
