To describe sport specialization in Canadian youth. To investigate associations with previous injury and physical performance.
Although sport specialization in Canadian junior high schools exist, it may be less common than previously reported. It was not associated with sex, grade, or school size. Level of association was not associated with history of injury nor a range of physical performance measures.

To describe the facilitators and barriers to implementation of a sport injury prevention program in junior high school physical education
Facilitators: evidence strength and quality, adaptability, implementation climate, culture, and having a high level of compatibility. Barriers: intervention complexity, planning, and readiness for implementation. Facilitators and barriers (depending on conteext): self-efficacy, execution, and individual identification with the organization

1,067 junior high school students (ages 11-15) participating in physical education classes in 12 schools in Calgary and surrounding area.
2014-2017 school years
Schools were randomized into the intervention group (a high-intensity neuromuscular training warm-up program, including aerobic, agility, strength, and balance components; 6 schools) or control group (a standard of practice warm-up including aerobic, dynamic and static stretching components; 6 schools). Teachers in each school implemented their warm-up program at the beginning of physical education classes over a 12-week period. A study therapist visited the schools on a weekly basis to assess any injuries sustained by participating students
To examine the effectiveness of a school-based sports injury prevention warm-up program to reduce injuries through neuromuscular training (NMT). Injuries were defined as any injury sustained through a sport or recreational activity that resulted in time loss, inability to complete a session, or medical attention.
A neuromuscular training program in junior high school physical education classes was effective in reducing sport-related injury by in girls, but not in boys. In girls, iSPRINT demonstrated a 46% reduction in all injuries, a 64% reducing in lower extremity injuries, and a 71% reduction in medical attention injuries when compared to girls in the control group.

To examine the effectiveness of a school-based high-intensity neuromuscular training program in reducing sport injury risk and improving health and fitness in youth.
A neuromuscular training program in junior high school physical education classes was effective in reducing sport-related injury and improving measures of adiposity and fitness.

To determine the reliability of eyes open and eyes open/closed balance measurements and to examine factors associated with balance.
Timed balance is an appropriate and reliable clinical measurement for use in adolescents and is influenced by previous injury.

To examine the effectiveness of a neuromuscular training program to reduce the risk of injury in youth
A neuromuscular training program was effective in the reduction of acute onset injuries in youth basketball and soccer. A less-specific program was protective of all sport injury when delivered in physical education class at a junior high school

There was a reduced injury risk for those doing the balance training program compared to normal controls
