The objective of this retrospective study was to gather big data using the Catapult wearable technology, develop an algorithm for musculoskeletal modeling, and longitudinally determine the workloads of male college soccer (football) athletes at the Division III (DIII) level over the course of a 12-week season. The results showed that over the course of a season, (1) the average match workload (432 \u00b1 47.7) was 1.5\u00d7 greater than the average training workload (252.9 \u00b1 23.3) for all positions, (2) the forward position showed the lowest workloads throughout the season, and (3) the highest mean workload was in week 8 (370.1 \u00b1 177.2), while the lowest was in week 4 (219.1 \u00b1 26.4). These results provide the impetus to enable the interoperability of data gathered from wearable devices into data management systems for optimizing performance and health.<\/jats:p>","DOI":"10.3390\/s24051463","type":"journal-article","created":{"date-parts":[[2024,2,26]],"date-time":"2024-02-26T03:34:04Z","timestamp":1708918444000},"page":"1463","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Wearable Devices and Digital Biomarkers for Optimizing Training Tolerances and Athlete Performance: A Case Study of a National Collegiate Athletic Association Division III Soccer Team over a One-Year Period"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2426-8795","authenticated-orcid":false,"given":"Dhruv R.","family":"Seshadri","sequence":"first","affiliation":[{"name":"Department of Bioengineering, Lehigh University, Bethlehem, PA 18015, USA"},{"name":"Department of Biomedical Engineering, Case Western Reserve University, Cleveland, OH 44106, USA"}]},{"given":"Helina D.","family":"VanBibber","sequence":"additional","affiliation":[{"name":"Sports Medicine Institute, University Hospitals Cleveland Medical Center, Cleveland, OH 44106, USA"},{"name":"Department of Orthopaedic Surgery, University Hospitals Cleveland Medical Center, Cleveland, OH 44106, USA"},{"name":"Department of Cognitive Science, Case Western Reserve University, Cleveland, OH 44106, USA"},{"name":"Department of Psychology, Case Western Reserve University, Cleveland, OH 44106, USA"}]},{"given":"Maia P.","family":"Sethi","sequence":"additional","affiliation":[{"name":"Department of Cognitive Science, Case Western Reserve University, Cleveland, OH 44106, USA"},{"name":"Department of Psychology, Case Western Reserve University, Cleveland, OH 44106, USA"}]},{"given":"Ethan R.","family":"Harlow","sequence":"additional","affiliation":[{"name":"Sports Medicine Institute, University Hospitals Cleveland Medical Center, Cleveland, OH 44106, USA"},{"name":"Department of Orthopaedic Surgery, University Hospitals Cleveland Medical Center, Cleveland, OH 44106, USA"}]},{"given":"James E.","family":"Voos","sequence":"additional","affiliation":[{"name":"Sports Medicine Institute, University Hospitals Cleveland Medical Center, Cleveland, OH 44106, USA"},{"name":"Department of Orthopaedic Surgery, University Hospitals Cleveland Medical Center, Cleveland, OH 44106, USA"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"23259671211055136","DOI":"10.1177\/23259671211055136","article-title":"Incidence of Injury for Professional Soccer Players in the United States: A 6-Year Prospective Study of Major League Soccer","volume":"10","author":"Forsythe","year":"2022","journal-title":"Orthop.
