Inertial measurement units (IMUs) are low-cost, non-invasive devices capable of estimating spatiotemporal gait-related metrics during overground locomotion. This study evaluated the accuracy and concurrent validity of a foot-mounted IMU system for estimating sprinting kinematics. (2) Method: Twenty-five elite and sub-elite athletes completed four maximal 10-metre fly efforts, with their kinematics measured concurrently using a three-dimensional motion analysis system and IMUs. (3) Result: The foot-mounted IMU system\u2019s root mean square errors for stride length and duration were 0.22 m and 0.04 s, respectively. Mean biases (95% level of agreement) were \u22120.67 m\u00a0\u00b7\u00a0s\u22121 (\u22121.19; \u22120.14) for peak velocity, \u22120.51 m\u00a0\u00b7\u00a0s\u22121 (\u22121.10; 0.09) for instantaneous velocity, and 0.17 m\u00a0\u00b7\u00a0s\u22122 (\u22121.04; 1.37) for instantaneous acceleration. Stride length, duration, and cadence were \u22120.07 m (\u22120.36; 0.23), 0.02 s (\u22120.02; 0.06), and \u22124.64 strides \u00b7\u00a0min\u22121 (\u221215.82; 6.53), respectively. (4) Conclusions: End users implementing this technology in research and practice should interpret this study\u2019s findings relative to their analytical objectives, logistical resources, and operational constraints. Therefore, its adoption should be guided by the specific performance metrics of interest and the extent to which the system\u2019s capabilities align with the outcomes the end user aims to achieve.<\/jats:p>","DOI":"10.3390\/s26010246","type":"journal-article","created":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T14:33:25Z","timestamp":1767191605000},"page":"246","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Quality Assessment of a Foot-Mounted Inertial Measurement Unit System to Measure On-Field Spatiotemporal Acceleration Metrics"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-8760-9408","authenticated-orcid":false,"given":"Marco","family":"Dasso","sequence":"first","affiliation":[{"name":"Institute for Health and Sport (IHeS), Victoria University, Melbourne, VIC 3000, Australia"},{"name":"High Performance Department, Western Bulldogs Football Club, Melbourne, VIC 3000, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5920-0363","authenticated-orcid":false,"given":"Grant","family":"Duthie","sequence":"additional","affiliation":[{"name":"School of Exercise Science, Australian Catholic University, Strathfield, NSW 2135, Australia"},{"name":"Sports Performance, Recovery, Injury, and New Technologies (SPRINT) Research Centre, Australian Catholic University, Strathfield, NSW 2135, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8330-0011","authenticated-orcid":false,"given":"Sam","family":"Robertson","sequence":"additional","affiliation":[{"name":"Institute for Health and Sport (IHeS), Victoria University, Melbourne, VIC 3000, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2745-2969","authenticated-orcid":false,"given":"Jade","family":"Haycraft","sequence":"additional","affiliation":[{"name":"Institute for Health and Sport (IHeS), Victoria University, Melbourne, VIC 3000, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"37","DOI":"10.2478\/hukin-2021-0010","article-title":"A new foot-mounted inertial measurement system in soccer: Reliability and comparison to global positioning systems for velocity measurements during team sport actions","volume":"77","author":"Waldron","year":"2021","journal-title":"J.
