Acceptability, Feasibility, and Effects of a Mindfulness-Based Intervention on the Quality of Life and Performance of the Brazilian Paralympic Boccia Team: Mixed Methods Case Study

This study evaluated the acceptability, feasibility, and effects on the quality of life and performance of a mindfulness-based intervention (MBI) for the Brazilian Paralympic Boccia Team. A longitudinal case study was used with evaluations before and after applications. A mixed design with quantitative and qualitative instruments was applied to 29 participants categorized as ATHLETE and NON-ATHLETE. Mindfulness training consisted of eight one-hour sessions with a four-hour 1st CYCLE, a four-hour 2nd CYCLE, and three follow-up evaluations (one, six, and 12 months after the baseline) with 10 maintenance sessions. Participants underwent an improvement in quality of life and performance mediated by a significant increase in attention levels. Regarding feasibility, the MBI received significant levels of approval and recommendation for Paralympic sports due to participants’ acquired ability to apply mindfulness in sports or quotidian life. Mindfulness programs may be acceptable, feasible, and effective for Paralympic teams, potentially improving quality of life and performance.
