In total, 21 professional soccer players were evaluated over 48 weeks during the full-season. The TM and TS were calculated based on the number of accelerations and decelerations at zone 1, zone 2 and zone 3, respectively. The results revealed that starters presented higher values compared to non-starters throughout the full season for all variables analyzed (all, p &lt; 0.05). Generally, there were higher values in the pre-season. Specifically, accelerations at zones 1, 2 and 3 revealed moderate to very large significance of the starters compared to non-starters over the full-season. Decelerations at zone 1, 2 and 3 presented moderate to nearly optimally significant greater weekly averages for starters compared to non-starters during the full season. In conclusion, the TM and TS values were higher for starters compared to non-starters through the full-season, which confirms that the training session does not provide a sufficient load to non-starter soccer players during the full-season.<\/jats:p>","DOI":"10.3390\/ijerph17186547","type":"journal-article","created":{"date-parts":[[2020,9,9]],"date-time":"2020-09-09T09:01:09Z","timestamp":1599642069000},"page":"6547","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":49,"title":["Comparisons of Accelerometer Variables Training Monotony and Strain of Starters and Non-Starters: A Full-Season Study in Professional Soccer Players"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7951-8977","authenticated-orcid":false,"given":"Hadi","family":"Nobari","sequence":"first","affiliation":[{"name":"Department of Exercise Physiology, Faculty of Sport Sciences, University of Isfahan, Isfahan 81746-7344, Iran"},{"name":"Sports Scientist, Sepahan Football Club, Isfahan 81887-78473, Iran"}]},{"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\u2013Polytechnic Institute of Santar\u00e9m, 2140-413 Rio Maior, Portugal"},{"name":"Research Centre in Sport Sciences, Health Sciences and Human Development, 5001-801 Vila Real, Portugal"},{"name":"Life Quality Research Centre, 2140-413 Rio Maior, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9813-2842","authenticated-orcid":false,"given":"Filipe Manuel","family":"Clemente","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"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7203-3168","authenticated-orcid":false,"given":"Jose Carmelo","family":"Adsuar","sequence":"additional","affiliation":[{"name":"HEME Research Group, Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4054-9132","authenticated-orcid":false,"given":"Jorge","family":"P\u00e9rez-G\u00f3mez","sequence":"additional","affiliation":[{"name":"HEME Research Group, Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6377-9950","authenticated-orcid":false,"given":"Jorge","family":"Carlos-Vivas","sequence":"additional","affiliation":[{"name":"HEME Research Group, Faculty of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4357-4269","authenticated-orcid":false,"given":"Jo\u00e3o Paulo","family":"Brito","sequence":"additional","affiliation":[{"name":"Sports Science School of Rio Maior\u2013Polytechnic Institute of Santar\u00e9m, 2140-413 Rio Maior, Portugal"},{"name":"Research Centre in Sport Sciences, Health Sciences and Human Development, 5001-801 Vila Real, Portugal"},{"name":"Life Quality Research Centre, 2140-413 Rio Maior, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,9]]},"reference":[{"key":"ref_1","unstructured":"Ekblom, B.
