Basketball performance is affected by the schedule congestion: NBA back-to-backs under the microscope

Teams experiencing highly competitive densities may be particularly exposed to performance breakdown and injury risk. The aim of this study was to analyse the association between fixture congestion cycles (playing back-to-back games, playing on one day's rest, playing on two day's rest, playing on three or more day's rest) and performance of NBA basketball teams. A total of 82 games from all teams participating in NBA 2016/2017 regular season were considered. Game-related statistics by fixture congestion cycles and game outcome were examined using the Pearson's Chi-Square test, Discriminant Analysis and Binary logistic regression. The results revealed that the likelihood of winning a game increased significantly from playing back-to-back games to having one day rest in between. Shooting efficacy-related statistics presented a considerable discriminatory power of the different fixture congestion cycles. In conclusion, fixture congestion cycles showed a significant impact on the game outcome and team performance. The findings may add value in the re-design of game schedules in the NBA as well as inform coaches to critically manage training load in order to enhance performance and reduce the risk of injury.

Automated summary
