Football Fans in Training (FFIT) is an effective, gender-sensitized, weight loss and healthy living program for overweight/obese men, delivered via professional football clubs. Hockey Fans in Training (Hockey FIT) is a new program adapted from FFIT for Canadian hockey. PURPOSE: To examine the impact of Hockey FIT on steps, self-esteem, mood, and self-rated health, 12 weeks after baseline (post program). METHODS: 80 male fans [35-65 years; body mass index (BMI) ≥ 28 kg/m2] of 2 Ontario Junior A hockey clubs were randomized to either intervention (Hockey FIT) or comparator (wait-list control), within a pilot, pragmatic randomized controlled trial (RCT). Hockey FIT involved 12 weekly, 90-minute group sessions delivered by trained coaches using club facilities. Each session combined classroom material, including evidence- based behaviour change techniques (e.g., self-monitoring, goal setting) and healthy eating advice (e.g., reducing portion size), with physical activity sessions. Prescriptive exercise (e.g., individualized target heart rates and pedometer-based incremental step targets) was incorporated throughout. We examined between-group differences in mean steps/day (7-day pedometer monitoring), self-esteem (Rosenberg scale), positive and negative affect (I-PANAS-SF scale), and self-rated health (EQ-5D-3L VAS score) using linear mixed effects regression models that accounted for club and age. RESULTS: Groups were similar at baseline [median (interquartile range): age: 48.0 (17.0) years; BMI: 35.1 (6.3) kg/m2]. 75% of men in the intervention group attended ≥ 6 sessions. At 12 weeks, the intervention group increased their daily steps to a greater extent than the comparator [difference between groups in mean change: 3127 (95% confidence interval: 1882 to 4372) steps/day, p
