Brief summary: The goal of the study is to determine effect of coach-led neuromuscular warm-up on non-contact, lower extremity (LE) injury rates among female athletes in a predominantly non-white public high school system. The investigators hypothesized the warm-up would reduce non-contact LE injuries.

Detailed description: We will recruit basketball and soccer coaches and their athletes from Chicago public high schools. We will randomize teams to intervention and control groups. We will train intervention coaches to implement a 20-minute neuromuscular warm-up and tracked training costs. Control coaches will use their usual warm-up. All coaches will report weekly athlete exposures (AEs) and injuries resulting in a missed practice/game. Research assistants will interview injured athletes. We will compare injury rates between control and intervention groups.

Eligibility criteria: Inclusion Criteria for High School Students (initial part of study - completed)

* plays basketball or soccer for a Chicago public high school team
* coaches basketball or soccer for a Chicago public high school team
* female, age 14-20

Inclusion Criteria for coaches (current part of study):

* Willing to implement a new warm-up before their team's practices and games
* Willing to complete a pre- and post-season survey before and after using the warm-up program for one season (surveys are attached).
* Willing to complete a pre- and post-workshop test before and after the workshop (tests are attached).
* Willing to allow study personnel to observe their implementation of the warm-up at up to three team practices or games.

Exclusion Criteria for coaches (current part of study) There are no separate exclusion criteria for coaches.
