Limited guidance exists for glucose level recommendations for the pediatric population; therefore, the purpose of this retrospective clinical chart review study was to determine the effects of VO2 max testing on blood glucose levels for adolescents with T1DM. A total of 22 adolescents (mean age = 15.6 \u00b1 1.8 years; male = 13, 59.1%) with a diagnosis of T1DM participated in a Bruce protocol for VO2 max from January 2019 through February 2020. A statistically significant reduction in glucose levels between pretest (&lt;30 min, mean = 191.1 mg\/dL \u00b1 61.2) and post-test VO2 max (&lt;5 min, mean = 166.7 mg\/dL \u00b1 57.9); t(21) = 2.3, p &lt; 0.05) was detected. The results from this current study can help guide health and fitness professionals in formulating glycemic management strategies in preparatory activities prior to exercise testing and during exercise testing.<\/jats:p>","DOI":"10.3390\/ijerph19095543","type":"journal-article","created":{"date-parts":[[2022,5,3]],"date-time":"2022-05-03T08:26:35Z","timestamp":1651566395000},"page":"5543","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Maximal Oxygen Uptake, VO2 Max, Testing Effect on Blood Glucose Level in Adolescents with Type 1 Diabetes Mellitus"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9398-2351","authenticated-orcid":false,"given":"Kristi M.","family":"King","sequence":"first","affiliation":[{"name":"Department of Health and Sport Sciences, University of Louisville, Louisville, KY 40292, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy","family":"McKay","sequence":"additional","affiliation":[{"name":"Norton Children\u2019s Hospital, Louisville, KY 40202, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bradly J.","family":"Thrasher","sequence":"additional","affiliation":[{"name":"Norton Children\u2019s Hospital, Louisville, KY 40202, USA"},{"name":"Wendy Novak Diabetes Center, Pediatric Endocrinology, School of Medicine, University of Louisville, Louisville, KY 40202, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kupper A.","family":"Wintergerst","sequence":"additional","affiliation":[{"name":"Norton Children\u2019s Hospital, Louisville, KY 40202, USA"},{"name":"Wendy Novak Diabetes Center, Pediatric Endocrinology, School of Medicine, University of Louisville, Louisville, KY 40202, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,3]]},"reference":[{"key":"ref_1","unstructured":"American College of Sports Medicine (ACSM), Liguori, G., Feito, Y., Fontaine, C., and Roy, B.
