Locomotor data were collected using\n                    a global navigation satellite system and included total distance, distance\n                    covered between 14\u201320, 20\u201325, 25\u201330, and&gt;30 km\/h, maximal speed, maximal\n                    accelerations and decelerations, and the number of accelerations and\n                    decelerations between 2 and 3 m\/s2. Congested fixtures (&lt;72 and\n                    72\u2013120 h) negatively affected locomotor activities compared to noncongested ones\n                    (&gt;168 h), with players covering less total distance (p=0.026) and\n                    distance at 14\u201320 km\/h (p=0.027) and performing fewer accelerations\n                        (p=0.001) and decelerations (p=0.022) between 2 and 3\n                        m\/s2. Additionally, interactions with accumulated kilometers\n                    traveled revealed that high accumulated distances in the days leading up to\n                    congested fixtures exacerbated reductions in locomotor performance\n                    (p&lt;0.05). Analysis of specific cases of consecutive congested fixtures\n                    showed a decline in locomotor activities after three matches within&lt;72 hours\n                    or four matches within&lt;120 hours. These findings highlight the importance of\n                    managing fixture schedules and travel distances to optimize player performance\n                    and reduce the risk of injury during congested match periods, with limiting\n                    players to short match sequences potentially being beneficial.<\/jats:p>","DOI":"10.1055\/a-2630-7119","type":"journal-article","created":{"date-parts":[[2025,6,7]],"date-time":"2025-06-07T18:30:21Z","timestamp":1749321021000},"page":"990-999","source":"Crossref","is-referenced-by-count":0,"title":["Identifying Match Sequence Thresholds to Mitigate Physical Decline\n                    During Congested Fixtures"],"prefix":"10.1055","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6797-1616","authenticated-orcid":false,"given":"Hugo","family":"Silva","sequence":"additional","affiliation":[{"name":"Research Center in Sports Sciences, Health Sciences and\n                    Human Development, CIDESD, University of Maia, Maia, Portugal"},{"name":"University of Maia, Maia, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-4062-7379","authenticated-orcid":false,"given":"Pedro","family":"Menezes","sequence":"additional","affiliation":[{"name":"Clube de Regatas do Flamengo, Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3733-0292","authenticated-orcid":false,"given":"Ibai","family":"Errekagorri","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sport, Faculty of\n                    Education and Sport, University of the Basque Country -
