Methods<\/jats:bold>:<\/jats:italic> Twelve participants swallowed temperature pills 12, 3, or 0.5\u00a0hours before completing 60\u00a0minutes of treadmill running, consuming 200\u00a0mL of room-temperature water every 15\u00a0minutes. Results<\/jats:bold>:<\/jats:italic> Pills ingested 0.5 or 3\u00a0hours before exercise resulted in significantly lower gastrointestinal temperature compared with those ingested 12\u00a0hours prior. Conclusions<\/jats:bold>:<\/jats:italic> These results indicate that ingesting pills closer to exercise with fluid ingestion may confound gastrointestinal temperature measurements, underlining the need for sufficient ingestion time before exercise to avoid interference with fluid intake.<\/jats:p>","DOI":"10.1123\/ijspp.2024-0440","type":"journal-article","created":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T10:39:44Z","timestamp":1742553584000},"page":"856-859","source":"Crossref","is-referenced-by-count":8,"title":["Gastrointestinal Temperature Measurement From Ingestible Pills Provided 3\u00a0Hours Preexercise Is Insufficient to Avoid Interference Caused by Tepid Water Ingestion"],"prefix":"10.1123","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-9401-6080","authenticated-orcid":true,"given":"Lo\u00efs","family":"Mougin","sequence":"first","affiliation":[{"name":"School of Sport, Exercise and Health Sciences, National Centre for Sport and Exercise Medicine, Loughborough University, Loughborough, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6194-5924","authenticated-orcid":true,"given":"Thomas G.","family":"Cable","sequence":"additional","affiliation":[{"name":"School of Sport, Exercise and Health Sciences, National Centre for Sport and Exercise Medicine, Loughborough University, Loughborough, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3941-9426","authenticated-orcid":true,"given":"Stephen A.","family":"Mears","sequence":"additional","affiliation":[{"name":"School of Sport, Exercise and Health Sciences, National Centre for Sport and Exercise Medicine, Loughborough University, Loughborough, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6514-5823","authenticated-orcid":true,"given":"Lewis J.","family":"James","sequence":"additional","affiliation":[{"name":"School of Sport, Exercise and Health Sciences, National Centre for Sport and Exercise Medicine, Loughborough University, Loughborough, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"4","key":"r1","series-title":"Physiol Rev","doi-asserted-by":"publisher","first-page":"1873","DOI":"10.1152\/PHYSREV.00038.2020","article-title":"Exercise under heat stress: thermoregulation, hydration, performance implications, and mitigation strategies","volume":"101","author":"P\u00e9riard JD","year":"2021","unstructured":"P\u00e9riard JD, Eijsvogels TMH, Daanen HAM.
