Background Acute and overload injuries are common among basketball players, especially in the lower limbs. Injuries are detrimental to both individual and team performance, such as negative injury consequences, loss of productivity and high cost of health care, and are critical components of any sport.

Objective This study aims to describe the systematic development of a basketball injury prevention program, and to evaluate the feasibility of this intervention.

Design Uncontrolled clinical trial.

Setting This study was divided into two steps:(1) the systematic development of the basketball-specific injury prevention program, based on the intervention mapping model,(2) the assessment of its feasibility (in terms of adherence, adequacy, motivation, relevance, difficulty, and preventive factors).

Patients (or Participants) Athletes 12 to 16 years old, who have performed at least 2 training sessions per week in the last 3 months and 15 games per season and have not suffered injuries at baseline.

Interventions (or Assessment of Risk Factors) This intervention was related to a pre-participation activity-guided warm-up program; health information relevant to sport, with a continuing education program, always with new relevant information will be addressed for the practice of sport. The content of the preventive program will be based on the combination of several preventive concepts, which are fundamental for the athlete’s better preparation.

Main Outcome Measurements We defined the outcomes as: sample characterization; adherence to the preventive program; study feasibility and complaints, and basketball-related diseases.

Results An injury prevention program called CBB 12 was proposed, based on three pillars, (1) health information, (2) behavior on and off the courts, and (3) guided warm-up pre-participation activity. The feasibility of the injury prevention program was assessed in a 12-week clinical trial of 68 basketball athletes, 2 coaches, 1 club. The questions about feasibility presented average ranging from 3.6 to 3.9 points among athletes, in a scale ranging from 1 to 4 points. The average preventive training CBB 12 (adherence) was 1.8 ± 0.9.

Conclusions The CBB 12 injury prevention program was positively evaluated by the athletes and the coaching staff, regarding its magnitude, adequacy and practicality.
