Background: Ecofit is an evidence-based multi-component physical activity intervention that integrates smartphone technology, the outdoor environment and social support. In a previous efficacy trial, significant improvements were found across several clinical, fitness, and mental health outcomes among adults at risk of (or with) type 2 diabetes. Methods:The aim of the present study is to evaluate the ecofit intervention in a 'real-world' setting using a scalable implementation model. Ecofit was adapted and implemented by a rural municipal council in the Upper Hunter Shire, New South Wales, Australia and evaluated using a single-group pre-post design. Inactive middle-aged and older adults (N=59) were recruited and assessed at 6-(primary time-point) and 20-weeks (follow-up).Result: Statistically significant improvements were found in this predominately overweight and obese sample for aerobic fitness, functional mobility, upper and lower body muscular fitness, systolic blood pressure and waist circumference at 6-weeks. At 20-weeks, effects were found for aerobic fitness, functional mobility, upper and lower body muscular fitness, and systolic blood pressure. Conclusion:Our findings support the effectiveness of the ecofit intervention delivered by municipal council staff following a brief training from the research team. This study provides valuable preliminary evidence to support of a larger implementation trial.
