Actions in partnership across sectors is one principle for the promotion of health behaviours. The objective of this study was to describe the participation in a sports club-based exercise programme-named JACKPOT-following an intervention in a health care setting. Focus was given to the recruitment into JACKPOT, the attendance level, and whether the different programme elements were implemented as intented. The practicability of the project was also retrospectively rated. Participants were 238 inactive people (50% women) between 30 and 65 years of age who attended a health resort. Of these, 77% were assigned to the intervention group (IG). The recruitment into the 12 JACKPOT sessions and the attendance levels were recorded via attendance lists. The implementation of the intervention standards was assessed with structured interviews and participatory observation. The Pragmatic Explanatory Continuum Indicator Summary (PRECIS)-2 tool served to rate the practicability of the project. Almost 50% of the IG subjects attended JACKPOT sessions at least once and 54% of the attenders visited ≥75% of the 12 sessions. Some of the programme elements were not delivered fully. The process evaluation results showed that the project worked in a real-world setting, and also uncovered potential reasons such as incomplete information delivery for the moderate recruitment and attendance level.
