Hockey Fans in Training (Hockey FIT): Rationale, design, and baseline characteristics from a cluster randomized controlled trial in men with overweight or obesity
Bibliographic record
Abstract
Background Previous research highlights the need for effective lifestyle interventions for men. Hockey Fans in Training (Hockey FIT) was developed as a pragmatic healthy lifestyle program tailored to men with overweight or obesity. This paper overviews the rationale, program details, and design of a recently completed cluster randomized controlled trial (RCT) of Hockey FIT. Participant engagement and baseline characteristics are also described. Methods The RCT evaluated the effectiveness, cost-effectiveness, and implementation of Hockey FIT. Forty-two sites in Canada and the United States were randomized to either the Hockey FIT intervention group or wait-list control group. Participants were men, aged 35–65 years, with a body mass index (BMI) ≥27 kg/m 2 . Hockey FIT is a group-based, off-ice, in-person healthy lifestyle program, including both a 3 - month active phase and a 9-month minimally-supported phase. Outcomes were assessed at baseline, 3, and 12 months. The primary outcome was weight loss at 12 months. Results The design of the cluster RCT incorporates evaluations of participant health outcomes, program implementation, and broader healthcare system impact. In the RCT, 1397 participants were assessed for eligibility and 997 were enrolled. Most participants heard about the program through social media or hockey team emails. Participants averaged 49 years of age, had BMI values of 35.3 kg/m 2 , were predominately white, and had varying levels of education. Conclusion The intended audience for Hockey FIT was recruited successfully, however, targeted recruitment to better engage diverse populations is warranted. This paper affords a useful outline for evaluating future lifestyle interventions tailored to men. This trial was registered on August 17, 2018 with ClinicalTrials.gov (identifier: NCT03636282 ).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
