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

PRIMARY OBJECTIVES

• To determine if policy interventions implemented through sporting organisations instigate and sustain healthy behaviour change within the sport setting.

• To determine if policy interventions implemented through sporting organisations instigate and sustain changes in attitudes, knowledge or awareness of healthy behaviour or intention to change behaviour within the sport setting.

SECONDARY OBJECTIVES

• To determine if policy interventions implemented through sporting organisations instigate and sustain healthy behaviour change outside the sport setting.

• To determine if policy interventions implemented through sporting organisations instigate and sustain changes in attitudes, knowledge or awareness of healthy behaviour or intention to change behaviour outside the sport setting.

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

• To determine if policy changes influence factors such as participation in sport.

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

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

• To determine if short term changes in attitudes, knowledge or awareness of healthy behaviour or intention to change behaviour are maintained at 12 months and beyond.

• To determine if multiple intervention strategies are more effective than single interventions in promoting and sustaining healthy behaviour change.
