Title: Investigating Circadian Advantages in the NFL: A Case Study of West Coast Teams Authors: Abhay Kopardekar, Archbishop Mitty High School, USA. Sean Pradhan, Menlo College, USA Abstract: Previous research in the National Football League (NFL) has shown that teams traveling eastward may gain circadian advantages during competition. The current study examines thirty years of performance using all West Coast teams subject to frequent travel in the NFL. We hypothesized that the West Coast teams would gain circadian advantages during eastward travel compared to travel within the same time zone, and when playing at their circadian peaks during the afternoon. Data for all away games played from the 1990 to 2019 seasons were collected from Pro- Football-Reference and FiveThirtyEight (n = 1,018).
