Twenty-one professional soccer players were daily monitored during 48 consecutive weeks. Total distance, sprint total distance (STD), high-speed running distance (HSRd), maximum speed, number of the repeated sprints, and body load (BL) were obtained during training and matches using a Wearable Inertial Measurement Unit. The wAW was determined for each external load measure. The wCW, wACWR, and wTM were calculated based on BL metric. Higher values of weekly STD were observed in lateral defenders\/wingers (LDW) compared to central defenders\/forwards (CDF) (p = 0.009; ES = Large) and midfielders (MDF) (p = 0.034; ES = Large). Additionally, weekly HSRd was higher in LDW vs. CDF (p = 0.016; ES = Large) and MDF (p = 0.011; ES = Large). The CDF presented a lower weekly number of repeated sprints than LDW (p = 0.021; ES = Large). In conclusion, weekly external load metrics were position-dependent over the season. Moreover, LDW a presented greater weekly STD, HSRd, and number of repeated sprints compared to other positions.<\/jats:p>","DOI":"10.3390\/app12031140","type":"journal-article","created":{"date-parts":[[2022,1,23]],"date-time":"2022-01-23T20:32:52Z","timestamp":1642969972000},"page":"1140","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Wearable Inertial Measurement Unit to Measure External Load: A Full-Season Study in Professional Soccer Players"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7951-8977","authenticated-orcid":false,"given":"Hadi","family":"Nobari","sequence":"first","affiliation":[{"name":"Department of Physical Education and Sports, University of Granada, 18010 Granada, Spain"},{"name":"Department of Physiology, School of Sport Sciences, University of Extremadura, 10003 C\u00e1ceres, Spain"},{"name":"Sports Scientist, Sepahan Football Club, Isfahan 81887-78473, Iran"},{"name":"Department of Exercise Physiology, Faculty of Educational Sciences and Psychology, University of Mohaghegh Ardabili, Ardabil 56199-11367, Iran"}]},{"given":"Luiz G.","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Department of Performance Analysis, Crici\u00fama Football Club, Crici\u00fama 88816-276, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4885-7316","authenticated-orcid":false,"given":"Rodrigo","family":"Aquino","sequence":"additional","affiliation":[{"name":"LabSport, Center of Physical Education and Sports, Federal University of Esp\u00edrito Santo, Vit\u00f3ria 29075-910, Brazil"}]},{"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"},{"name":"Instituto de Telecomunica\u00e7\u00f5es, Delega\u00e7\u00e3o da Covilh\u00e3, 1049-001 Lisboa, Portugal"}]},{"given":"Manuchehr","family":"Rezaei","sequence":"additional","affiliation":[{"name":"Sports Scientist, Sepahan Football Club, Isfahan 81887-78473, Iran"}]},{"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\/0000-0002-4054-9132","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\/0000-0003-2590-3276","authenticated-orcid":false,"given":"Basilio","family":"Pueo","sequence":"additional","affiliation":[{"name":"Institute for Computing Research, Physical Education and Sports, Faculty of Education, University of Alicante, 03013 Alicante, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7677-5070","authenticated-orcid":false,"given":"Luca Paolo","family":"Ardig\u00f2","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Biomedicine and Movement Sciences, School of Exercise and Sport Science, University of Verona, 37131 Verona, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"533","DOI":"10.1007\/s40279-016-0591-0","article-title":"Relationships Between Training Load Indicators and Training Outcomes in Professional Soccer","volume":"47","author":"Jaspers","year":"2017","journal-title":"Sports Med."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"457","DOI":"10.1123\/ijspp.2019-0060","article-title":"Measurement Characteristics of Athlete Monitoring Tools in Professional Australian Football","volume":"15","author":"Ryan","year":"2019","journal-title":"Int.
