This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

PRIMARY OBJECTIVES

• To determine the effects of interventions implemented through sporting organisations for increasing (active and non‐active) participation in organised sport.

SECONDARY OBJECTIVES

• To determine if interventions are more successful with particular participants, grouped by, for example socio‐economic status, gender, age, ethnicity, geographical location and individual or team sports.

• To determine if the success of the interventions is dependant on particular process indicators (ie. those that describe why and how a particular intervention has worked).

• To determine if the success of the interventions is dependant on particular contextual factors (eg. concurrent media campaigns at the time of implementation).

• To determine if multiple intervention strategies are more effective than single interventions in increasing participation.

• To determine if different types of interventions are more effective than others.

• To determine if short term changes are maintained at 12 months and beyond.
