IMPALA.net – “International Network to Implement EU Physical Activity GuideLines on Infrastructure Development” links 17 research institutes, sport organizations and political actors from Austria, Finland, Germany, Italy, Lithuania and the Netherlands.IMPALA.net responds to demands by the 2013 EU HEPA Council Recommendation in the field of infrastructure development through adoption and implemention of the “European Guidelines for Improving Infrastructures for Leisure-Time Physical Activity in the Local Arena [IMPALA Guidelines]”. The IMPALA Guidelines include practical, policy-oriented activities on the development of infrastructures (sport facilities, recreational infrastructures, green and urban space).This will be accomplished through completion of two aims: (1) to improve implementation of policy for HEPA infrastructure development at the national level and (2) to position sport organisations’ to take leading roles as promoters of HEPA through sport via capacity developmentProject activities will involve interactive, participatory processes that build bridges between policy and practice both vertically (e.g. EU-level to the local level) and horizontally (e.g. multi-sectorally). Aim 1 will be achieved through establishment of cross-sectoral, National Alliances in six EU Member States. The National Alliances will cooperate at the international level to carry out a policy development, training and implementation scheme that will result in the adoption of National Action Plans to implement the IMPALA Guidelines. Activities will also involve development of scale-up actions and strategies to promote feasibility of implementation at the grassroots level. For aim 2, national sport organisations will be integral to developing, implementing and participating in an international Winter School for Stakeholders. This will strengthen their standing to lead tasks including the creation of National Alliances and developing of National Action Plans.
