"What do we think?": a qualitative exploratory study of acceptability and experiences of individuals with resistant hypertension after completing a physical exercise program (the EnRICH trial).

Purpose: Aerobic exercise training programs decrease blood pressure in individuals with resistant hypertension. However, participants' experiences regarding exercise training participation are unknown and often undervalued. Therefore, participant's experiences and program acceptability of the exercise arm of the EnRicH trial, a randomized clinical trial investigating the effect of a 12-week aerobic exercise training program in individuals with resistant hypertension were analysed.

Methods: An exploratory qualitative study was conducted with twenty individuals with resistant hypertension (11 males, mean age 58.9 ± 8.9 years), after the exercise program. Four focus group interviews were performed to explore participants' perspectives. The interviews were digitally audio-recorded, transcribed verbatim, and subjected to thematic analysis.

Results: Five themes emerged from the data analyses: 1) main impacts of participating in the exercise program; 2) facilitators of adherence; 3) perceived barriers; 4) perception of the program structure; and 5) global satisfaction with the program. Positive physical and emotional changes were reported, associated with reduced perceived stress and irritability, and decreased blood pressure. Adherence to the exercise program was facilitated by personalized supervision and feedback, the personal commitment to attend the training sessions, and different schedule options. Lack of motivation, peer support, physical health limitations, and difficulty in conciliating schedules were identified as barriers to the maintenance of exercise training after the program.

Conclusion: The qualitative analysis demonstrates the acceptability of the program. Peer and health professional's support, commitment to health professionals, and boosting individual-perceived advantages are key-points to promote participants adherence.
