Great question Italy. It depends on what setting the athletic trainer is working in, but typically there are no overnight shifts. The “traditional” athletic trainer setting is at a secondary school or college working directly with the sports teams. Working at a high school will have some late nights, with night football games having you finish up 10 or 11:00. Working with a college team will have you travel, depending on what sport you are working with. A basketball team has more games and travels more frequently than a football team, so it depends. Growing fields in athletic training are in a doctors office (typically with sports medicine or orthopedic physicians) and the industrial setting. Working at a doctors office will typically give you a regular 9-5 workday. The industrial setting can see you working night shifts if the warehouse/factory/etc have night shifts. If you are looking at a “traditional” setting then there will be some later nights, but you shouldn’t expect to be working through the night.
