Implementation of an app-based blended mindfulness intervention in a Bundesliga Youth Academy targeting goalkeepers: A case study

Integrating extensive sport psychological interventions into the daily routine of young football players poses a problem. This case study aimed to describe the implementation of an app-based blended mindfulness intervention in a German Bundesliga youth academy to improve goalkeepers’ (n = 6) attention. A mindfulness app was combined with regular group workshops. The study included an outcome evaluation based on pre- and postintervention assessments of attention performance and process evaluation based on recorded training time and collected qualitative data. The results showed an improvement in the players’ Frankfurt Attention Inventory-2 L scores and K scores. The training time with the app was low (M = 30.51 min), but high (M = 200.00 min) without the app. To implement an app-based intervention successfully, the results imply that players need more assistance with the app, and time management and informal training should be incorporated into sport-specific exercises.
