Twenty-eight men from the Chinese Taipei U\u221220 national futsal team were analyzed. Comparisons of training days revealed that the total distance was significantly smaller on day 1 (d = \u22121.22) and day 6 (d = \u22121.95) than on day 3. The sRPE values were significantly lower on day 1 than days 4 (d = \u22121.53), 5 (d = \u22122.07), and 6 (d = \u22122.59). The relationships between training load and recovery parameters revealed moderate correlations between the DOMS and the sRPE recorded one (r = \u22120.321) and two days before training (r = \u22120.289). It is possible conclude that first day imposed a smaller external load and internal load, and that the internal load had a greater dependent relationship with reported DOMS and fatigue during the training camps.<\/jats:p>","DOI":"10.3390\/ijerph17061843","type":"journal-article","created":{"date-parts":[[2020,3,12]],"date-time":"2020-03-12T12:22:51Z","timestamp":1584015771000},"page":"1843","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Psychobiological Changes during National Futsal Team Training Camps and Their Relationship with Training Load"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9813-2842","authenticated-orcid":false,"given":"Filipe Manuel","family":"Clemente","sequence":"first","affiliation":[{"name":"Escola Superior Desporto e Lazer, Instituto Polit\u00e9cnico de Viana do Castelo, Rua Escola Industrial e Comercial de Nun\u2019\u00c1lvares, 4900-347 Viana do Castelo, Portugal"},{"name":"Instituto de Telecomunica\u00e7\u00f5es, Delega\u00e7\u00e3o da Covilh\u00e3, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1772-1272","authenticated-orcid":false,"given":"Ana Filipa","family":"Silva","sequence":"additional","affiliation":[{"name":"Escola Superior Desporto e Lazer, Instituto Polit\u00e9cnico de Viana do Castelo, Rua Escola Industrial e Comercial de Nun\u2019\u00c1lvares, 4900-347 Viana do Castelo, Portugal"},{"name":"N2i, Polytechnic Institute of Maia, 4475-690 Maia, Portugal"},{"name":"The Research Centre in Sports Sciences, Health Sciences and Human Development (CIDESD), 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8681-0642","authenticated-orcid":false,"given":"Hugo","family":"Sarmento","sequence":"additional","affiliation":[{"name":"Research Unit for Sport and Physical Activity (CIDAF), Faculty of Sport Sciences and Physical Education, University of Coimbra, Coimbra, 3040-156 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2035-3279","authenticated-orcid":false,"given":"Rodrigo","family":"Ramirez-Campillo","sequence":"additional","affiliation":[{"name":"Human Performance Laboratory.
