The aim of this study was to analyse the association between fixture congestion cycles (playing back\u2010to\u2010back 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\u2010related statistics by fixture congestion cycles and game outcome were examined using the Pearson's Chi\u2010Square test, Discriminant Analysis and Binary logistic regression. The results revealed that the likelihood of winning a game increased significantly from playing back\u2010to\u2010back games to having one day rest in between. Shooting efficacy\u2010related 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\u2010design 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.<\/jats:p>","DOI":"10.1080\/17461391.2020.1736179","type":"journal-article","created":{"date-parts":[[2020,3,14]],"date-time":"2020-03-14T08:08:54Z","timestamp":1584173334000},"page":"26-35","update-policy":"https:\/\/doi.org\/10.1080\/tandf_crossmark_01","source":"Crossref","is-referenced-by-count":58,"title":["Basketball performance is affected by the schedule congestion: NBA back\u2010to\u2010backs under the microscope"],"prefix":"10.1002","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4675-2959","authenticated-orcid":false,"given":"Pedro T.","family":"Esteves","sequence":"first","affiliation":[{"name":"Polytechnic Institute of Guarda Guarda Portugal"},{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development, CIDESD, CreativeLab Research Community Vila Real Portugal"}]},{"given":"Kazimierz","family":"Mikolajec","sequence":"additional","affiliation":[{"name":"Academy of Physical Education Katowice Poland"}]},{"given":"Xavier","family":"Schelling","sequence":"additional","affiliation":[{"name":"Institute for Health and Sport (iHeS) Victoria University Melbourne Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2335-9991","authenticated-orcid":false,"given":"Jaime","family":"Sampaio","sequence":"additional","affiliation":[{"name":"Research Centre in Sports Sciences, Health Sciences and Human Development, CIDESD, CreativeLab Research Community Vila Real Portugal"},{"name":"Universidade de Tr\u00e1s\u2010os\u2010Montes e Alto Douro Vila Real Portugal"}]}],"member":"311","published-online":{"date-parts":[[2020,3,14]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/0470114754"},{"key":"e_1_2_8_3_1","unstructured":"Chan H.
