Head impacts in collision sports such as football are a public health concern, as repetitive head impacts, even if a concussion is not suspected, have negative effects on brain health. This study has partnered with a community stakeholder group to create a safety program for youth football named "COmmunities Aligned to reduce Concussion and Head impact exposure (COACH)", which seeks to improve knowledge and skills of youth coaches in effective and safe practice planning and to change attitudes and beliefs to prevent head impacts and promote safety. To continue advancing COACH as an approach to prevent head injuries in youth football, this R01 Research Project Grant will determine the ability of youth football organizations to adopt COACH and test if COACH is effective in reducing head impacts, concussion, and negative effects of brain health while monitoring how the program is implemented.
Football has a high risk of concussion and incidence of subconcussive head impacts which have long-lasting negative effects on brain health. With roughly 3.5 million athletes participating in youth football each year, there is a critical need to reduce head impact exposure and concussion risk. Over an entire season, most of an athlete's head impact exposure is attributed to practice. Coach-directed activities (e.g., practice drills) influence the frequency and severity of head impact exposure. Practices are amenable to intervention; however, youth football leagues are often community-run organizations with limited resources, making implementation and enforcement of injury prevention strategies a challenge. Thus, engaging community members is essential for successful development, implementation, and sustenance of interventions. This study partnered with a community stakeholder group to co-design and implement an evidence-based intervention program: COmmunities Aligned to reduce Concussion and Head impact exposure (COACH). COACH seeks to improve knowledge and skills of youth football coaches in effective practice planning that incorporates safe drills and to change attitudes and beliefs toward contact in practice. COACH has been pilot tested in two teams and shown to be acceptable and feasible. A critical next step of this research is the pragmatic evaluation of the effectiveness of COACH on a larger scale, while identifying factors that influence implementation. This study addresses this critical next step by determining the capacity of youth football organizations to adopt COACH and by testing COACH's effectiveness while monitoring the implementation process.

| COmmunities Aligned to reduce Concussion and Head impact exposure (COACH) Intervention | Behavioral | COmmunities Aligned to reduce Concussion and Head impact exposure (COACH) includes use of practice plans and a resource booklet aligned with the National Federation for High School guidelines for contact in practice. Coaches will also attend a pre-season coaches' clinic and be paired with a peer mentor during the season. |
| Measure | Description | Time Frame |
|---|---|---|
| Number of practice impacts | Total number of head impacts measured during the season in practices - 0-500 impacts | 3 months |
| linear acceleration of practice impacts | Median peak resultant linear acceleration measured during the season in practices - 8-45 g of linear acceleration | 3 months |
| rotational acceleration of practice impacts | Median peak resultant rotational acceleration measured during the season in practices - Median peak resultant linear acceleration measured during the season in practices - 8-45 g of linear acceleration - 100-1500 rad/s^2 | 3 months |
| Change in verbal memory composite (ImPACT) scores | Pre- to post-season change in attentional processes, learning, and memory within the verbal domain - range: 60-100; The composite score represents the average performance across three subtasks. A higher score indicates better performance. | 3 months |
| Change in visual memory composite (ImPACT) scores | Pre- to post-season change in visual attention and scanning, learning, and memory - range :40-100 The composite score represents the average performance across two subtasks. A higher score indicates better performance. | 3 months |
| Change in visual motor speed composite (ImPACT) scores | Pre- to post-season change in visual processing, learning and memory, and visual-motor response speed - range: 20-50 The composite score represents the average performance across two subtasks. A higher score indicates better performance. |
| Measure | Description | Time Frame |
|---|---|---|
| Intervention fidelity percentage of implementation | Implementation score representing the percentage of practices the intervention was implemented as prescribed - 0-100% - higher percent denoting more implementation | 3 months |
| Adaptation of the intervention (AIM) score |

| Change in reaction time composite (ImPACT) scores | Pre- to post-season change in response speed - range: 0-1; The composite score represents the average performance across three subtasks. A lower score indicates better performance. | 3 months |
| Change in Flanker Task (NIH Toolbox) Scores | Pre- to post-season change in inhibitory control and attention; range: 0-10 - Scoring is based on a combination of accuracy and reaction time. A higher score indicates better performance. | 3 months |
| Change in pattern comparison (NIH Toolbox) Scores | Pre- to post-season change in processing speed; range: 0-130 - Raw score is the number of items correctly in 85 seconds; score is then converted to a normative standard score. A higher score indicates better performance. | 3 months |
| Change in list sorting (NIH Toolbox) Scores | Pre- to post-season change in working memory; range: 0-26 - Scored by summing the total number of items correctly recalled and sequenced, then converted to a nationally normed score. A higher score indicates better performance. | 3 months |
| Change in Postural Control Scores | participants will complete two 30-second trials (one with eyes opened, one with eyes closed). Five measurements will be calculated at each time point (pre- and post-season): anterior-posterior sway, medial-lateral sway, path length, maximum path velocity, and center of pressure area. | 3 months |
