Thus, the study aim was to analyze the agreement between different accelerometry-based external load indicators (ABELIs) available in sport science. A U-16 male soccer team was assessed during three official matches, divided by periods, to obtain 3-D accelerometry data (x, y and z axes). An average of 1,420,000 data points was analyzed per axis per player. The ABELIs were calculated using this information, and the agreement between them was explored. The following ABELIs were considered after a literature review: AcelT, Player LoadRT, PlayerLoadTM, Impulse Load, Player LoadRE and Total Load. In order to compare ABELIs, two analyses were performed using: (1) absolute data; and (2) normalized and centered data (Z-scores). In absolute and centered data, very large to nearly perfect correlations (1st period: r &gt; 0.803, p &gt; 0.01; 2nd period: r &gt; 0.919; p &gt; 0.01) were found. Instead, very large differences were found in absolute values (bias = \u2212579,226.6 to 285,931.1; t = \u2212224.66 to 213.91, p &lt; 0.01), and no differences in scaled and centered values (bias = 0; t = 1; p = 1). In conclusion, considering the different output (magnitude and units) among ABELIs, the standardization of a universal index to calculate accelerometer load is needed in order to make possible between-study comparison.<\/jats:p>","DOI":"10.3390\/ijerph16245101","type":"journal-article","created":{"date-parts":[[2019,12,13]],"date-time":"2019-12-13T11:27:22Z","timestamp":1576236442000},"page":"5101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Accelerometry-Based External Load Indicators in Sport: Too Many Options, Same Practical Outcome?"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4084-8124","authenticated-orcid":false,"given":"Carlos D.","family":"G\u00f3mez-Carmona","sequence":"first","affiliation":[{"name":"Optimization of Training and Sport Performance Research Group (GOERD), Sport Science Faculty, University of Extremadura, 10005 Caceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9091-0897","authenticated-orcid":false,"given":"Jos\u00e9","family":"Pino-Ortega","sequence":"additional","affiliation":[{"name":"Department of Physical Activity and Sport, International Excellence Campus \u201cMare Nostrum\u201d, Sport Science Faculty, Universidad de Murcia, San Javier, 30720 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8791-6836","authenticated-orcid":false,"given":"Braulio","family":"S\u00e1nchez-Ure\u00f1a","sequence":"additional","affiliation":[{"name":"Program of Exercise Science and Health (PROCESA), School of Human Movement Science and Quality of Life, Universidad Nacional, Heredia 86-3000, Costa Rica"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6009-4086","authenticated-orcid":false,"given":"Sergio J.","family":"Ib\u00e1\u00f1ez","sequence":"additional","affiliation":[{"name":"Optimization of Training and Sport Performance Research Group (GOERD), Sport Science Faculty, University of Extremadura, 10005 Caceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0717-8827","authenticated-orcid":false,"given":"Daniel","family":"Rojas-Valverde","sequence":"additional","affiliation":[{"name":"Research Center of Sport and Health Diagnosis (CIDISAD), School of Human Movement Science and Quality of Life, Universidad Nacional, Heredia 86-3000, Costa Rica"},{"name":"Group in Updates for Sport Training and Physical Conditioning (GAEDAF), Sport Science Faculty, University of Extremadura, 10005 Caceres, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"587","DOI":"10.1123\/ijspp.2015-0331","article-title":"Training Load and Player Monitoring in High-Level Football: Current Practice and Perceptions","volume":"11","author":"Akenhead","year":"2016","journal-title":"Int.
