Twenty professional and experienced soccer players participated in a cross-sectional field study using three conditions: not informed on the duration of the SSG, which ended after 20 min (Unknown Condition); briefed about playing the SSG for 10 min, but after they completed the 10-min game, they were requested to complete another 10 min (Partial Condition) and informed before that they would play for 20 min (Known Condition). A global positioning system was used to measure the total distance covered and distances of different exercise training zones (walking to sprinting) and to access the dynamic players positioning through the distance from each player to all the teammates and opponents. Additionally, approximate entropy was measured to identify the regularity pattern of each gathered individual variable. The results indicate that the first 10 min of each scenario presented a higher physical impact independently of the initial information. During this time, the tactical behaviour also revealed higher variability. An increase in the distance of the teammates during the second period of 10-min for the Known scenario was also found, which may result from a lower pacing strategy. This study showed that the prior knowledge of the task duration led to different physical and tactical behaviours of the players. Furthermore, the relationship between the physical impact and the regularity of team game patterns should be well analysed by the coach, because the physical impact may be harmful to the development of the collective organization of the team.<\/jats:p>","DOI":"10.3390\/ijerph17113843","type":"journal-article","created":{"date-parts":[[2020,5,28]],"date-time":"2020-05-28T10:02:45Z","timestamp":1590660165000},"page":"3843","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Effects of Knowing the Task\u2019s Duration on Soccer Players\u2019 Positioning and Pacing Behaviour during Small-Sided Games"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7530-512X","authenticated-orcid":false,"given":"Ricardo","family":"Ferraz","sequence":"first","affiliation":[{"name":"Department of Sport Sciences, University of Beira Interior, 6200-001 Covilh\u00e3, Portugal"},{"name":"Research Centre in Sports, Health and Human Development, CIDESD; 5001-801 Vila Real, Portugal"},{"name":"Castelo Branco Football Association, Research Department, 6000-050 Castelo Branco, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7874-4104","authenticated-orcid":false,"given":"Bruno","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Departamento de Desporto e Sa\u00fade, Escola de Ci\u00eancias e Tecnologia, Universidade de \u00c9vora, 7000-645 \u00c9vora, Portugal"},{"name":"Comprehensive Health Research Center (CHRC), Universidade de \u00c9vora, 7000-645 \u00c9vora, Portugal"},{"name":"Portuguese Football Federation, Portugal Football School, 1495-433 Oeiras, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6605-9505","authenticated-orcid":false,"given":"Diogo","family":"Coutinho","sequence":"additional","affiliation":[{"name":"Research Centre in Sports, Health and Human Development, CIDESD; 5001-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6671-6229","authenticated-orcid":false,"given":"Rafael","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Sports Science School of Rio Maior\u2014Polytechnic Institute of Santar\u00e9m, 2040-413 Rio Maior, Portugal"},{"name":"Life Quality Research Centre, Polytechnic Institute of Santar\u00e9m, 2040-413 Rio Maior, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2165-2687","authenticated-orcid":false,"given":"Bruno","family":"Travassos","sequence":"additional","affiliation":[{"name":"Department of Sport Sciences, University of Beira Interior, 6200-001 Covilh\u00e3, Portugal"},{"name":"Research Centre in Sports, Health and Human Development, CIDESD; 5001-801 Vila Real, Portugal"},{"name":"Portuguese Football Federation, Portugal Football School, 1495-433 Oeiras, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2335-9991","authenticated-orcid":false,"given":"Jaime","family":"Sampaio","sequence":"additional","affiliation":[{"name":"Research Centre in Sports, Health and Human Development, CIDESD; 5001-801 Vila Real, Portugal"}]},{"given":"M\u00e1rio","family":"C.
