Twelve players participated in this study (age, 28.6 \u00b1 2.7 years; height, 182.1 \u00b1 8.6 cm; body mass, 75.3 \u00b1 8.2 kg). External intensity was measured by total duration, total distance, average speed, high-speed running distance, sprint distance, maximal speed and body load. In general, there was higher intensity in OMs compared with FMs for all variables. The first half showed higher intensities than the second half, regardless of the type of the match. Specifically, OMs showed higher values for total sprint distance (p = 0.012, ES = 0.59) and maximal speed (p &lt; 0.001, ES = 0.27) but lower value for body load (p = 0.038, ES = \u22120.42) compared to FMs. The first half of FMs only showed lower value for body load (p = 0.004, ES = \u22120.38) than FMs, while in the second half of OMs, only total distance showed a higher value than FMs (p = 0.013, ES = 0.96). OMs showed higher demands of high intensity, questioning the original assumption of FMs demands. Depending on the period of the season that FMs are applied, coaches may consider requesting higher demands from their teams.<\/jats:p>","DOI":"10.3390\/healthcare9121708","type":"journal-article","created":{"date-parts":[[2021,12,8]],"date-time":"2021-12-08T23:30:00Z","timestamp":1639006200000},"page":"1708","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Variability of External Intensity Comparisons between Official and Friendly Soccer Matches in Professional Male Players"],"prefix":"10.3390","volume":"9","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"}]},{"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, Polytechnic Institute of Santar\u00e9m, 2140-413 Rio Maior, Portugal"},{"name":"Research Center 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\/0000-0002-4054-9132","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\/0000-0001-6671-6229","authenticated-orcid":false,"given":"Rafael","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Sports Science School of Rio Maior, Polytechnic Institute of Santar\u00e9m, 2140-413 Rio Maior, Portugal"},{"name":"Research Center 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":[[2021,12,8]]},"reference":[{"key":"ref_1","first-page":"210","article-title":"SOS to the Soccer World.
