This research was using a total sampling method. A total of 19 UNNES soccer athletes were involved as research subjects. Data on nutritional status and energy intake were analyzed to evaluate the success of participatory action research. Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ) used to take dietary energy intake data, Nutrition status measured by BMI using Seca scales and microtome.
