The ATS is unique in several regards. It takes a whole-person approach, addressing cognitive, emotional, physical, social, occupational, financial, behavioral, and overall well-being outcomes. It encompasses a wide range of sports, including those with limited funding and notoriety. It looks at all levels of participation, from those who never competed at the elite level through the collegiate, professional and Olympic ranks. In this way, the study can compare athletes across sport, demographics, position played, time played, and levels of participation. Finally, the ATS uses sophisticated online survey methods to streamline the data collection process, thereby saving time for our participants and improve the accuracy and range of our analyses.
