Feasibility of the intervention was good, acceptance also. According to telephone interviews carried out after 12 weeks, similar changes in moderate intensity physical activity behaviour were observed in three intervention and three control units with 175 and 167 soldiers respectively. There were indications for effects on vigorous intensity activities and strength training, but they did not quite reach statistical significance. Adaptations have been made in the questionnaires and the intervention material. We believe that the intervention can make an important contribution to addressing physical inactivity in a militia army.enPhysical activity Counselling Swiss Armyarticle
