Methods: Fifteen trained athletes (8 males, 7 females) completed assessments of anthropometry, estimated one-repetition maximums (bench press, back squat, deadlift), squat jump (SJ), maximal oxygen uptake (VO2max), ventilatory responses (V\u02d9E), and heart rate (HR). Spearman, Pearson, and partial correlations were calculated with Holm and false discovery rate (FDR) corrections. Results: Males displayed greater body mass, lean and muscle mass, maximal strength, and aerobic capacity than females (all Holm-adjusted p &lt; 0.01). Experienced athletes completed Fran faster than beginners despite broadly similar anthropometric and aerobic profiles. In the pooled sample, WOD time showed moderate negative relationships with estimated 1RM back squat (\u03c1 = \u22120.54), deadlift (\u03c1 = \u22120.56), and bench press (\u03c1 = \u22120.65) before correction; none remained significant after Holm\/FDR adjustment, and partial correlations controlling for training years were further attenuated. Conclusions: This exploratory study provides preliminary evidence suggesting that maximal strength may contribute to Fran performance, whereas conventional aerobic measures were less influential. However, given the very small sample (n = 15, 8 males and 7 females) and the fact that no relationships remained statistically significant after correction for multiple testing, the results must be regarded as preliminary, hypothesis-generating evidence only, requiring confirmation in larger and adequately powered studies.<\/jats:p>","DOI":"10.3390\/jfmk10040387","type":"journal-article","created":{"date-parts":[[2025,10,6]],"date-time":"2025-10-06T13:33:41Z","timestamp":1759757621000},"page":"387","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Exploratory Analysis of the Correlations Between Physiological and Biomechanical Variables and Performance in the CrossFit\u00ae Fran Benchmark Workout"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-5634-9661","authenticated-orcid":false,"given":"Alexandra","family":"Malheiro","sequence":"first","affiliation":[{"name":"Department of Sport Sciences, University of Beira Interior, 6201-001 Covilh\u00e3, Portugal"},{"name":"Research Center in Sports Sciences, Health Sciences, and Human Development (CIDESD), 6201-001 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0184-6780","authenticated-orcid":false,"given":"Pedro","family":"Forte","sequence":"additional","affiliation":[{"name":"Research Center in Sports Sciences, Health Sciences, and Human Development (CIDESD), 6201-001 Covilh\u00e3, Portugal"},{"name":"Department of Sports, Instituto Polit\u00e9cnico de Bragan\u00e7a, 5301-854 Bragan\u00e7a, Portugal"},{"name":"Department of Sports, Higher Institute of Educational Sciences of the Douro, 4560-708 Penafiel, Portugal"},{"name":"Research Center for Active Living and Wellbeing (LiveWell), Instituto Polit\u00e9cnico de Bragan\u00e7a, 5301-854 Bragan\u00e7a, Portugal"}]},{"given":"David","family":"Rodr\u00edguez Rosell","sequence":"additional","affiliation":[{"name":"Physical Performance and Sports Research Center, Universidad Pablo de Olavide, 41013 Seville, Spain"},{"name":"Department of Sport and Informatics, Universidad Pablo de Olavide, 41013 Seville, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6653-0616","authenticated-orcid":false,"given":"Diogo L.","family":"Marques","sequence":"additional","affiliation":[{"name":"Department of Sport Sciences, University of Beira Interior, 6201-001 Covilh\u00e3, Portugal"},{"name":"Research Center in Sports Sciences, Health Sciences, and Human Development (CIDESD), 6201-001 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5812-1580","authenticated-orcid":false,"given":"M\u00e1rio C.","family":"Marques","sequence":"additional","affiliation":[{"name":"Department of Sport Sciences, University of Beira Interior, 6201-001 Covilh\u00e3, Portugal"},{"name":"Research Center in Sports Sciences, Health Sciences, and Human Development (CIDESD), 6201-001 Covilh\u00e3, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"134","DOI":"10.15294\/ajpesh.v1i2.52589","article-title":"Injury causes and recovery management strategies among Singapore crossfitters","volume":"1","author":"Tan","year":"2021","journal-title":"ACPES J.
