Direct comparative research between endurance and strength\u2013power athletes remains limited. This study aimed to evaluate and compare nutritional knowledge, dietary habits, sleep quality, and Body Mass Index between ultramarathon runners and American football players, as well as to explore independent predictors of sleep quality. Methods: A cross-sectional study was conducted among 231 male athletes. To address group size disparity and mitigate statistical bias, a random undersampling technique was applied to create a balanced cohort of 86 athletes comprising 43 ultramarathon runners and 43 American football players. Nutritional parameters were assessed using the Kom-PAN questionnaire. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index. Between-group comparisons were performed using the Mann\u2013Whitney U test with False Discovery Rate correction. An integrated multiple regression model was constructed to identify predictors of global sleep quality. Results: Ultramarathon runners demonstrated significantly better overall sleep quality (p = 0.026) and higher nutritional knowledge (p &lt; 0.001) compared to American football players. Differences in adherence to pro-healthy and non-healthy dietary patterns were not statistically significant after False Discovery Rate correction. The integrated multiple regression model revealed that the athletic discipline was the primary independent predictor of global sleep quality (p = 0.001), while dietary variables did not exhibit a significant independent effect. Furthermore, higher Body Mass Index was independently associated with better sleep scores within the multivariate model (p = 0.008). Conclusions: Significant sport-specific differences exist in BMI, nutritional knowledge, and sleep quality. Global sleep quality appears to be primarily associated with the specific physiological and environmental demands of the athletic discipline rather than individual dietary factors, which were not independently significant in the multivariable model. These findings suggest that recovery strategies in strength\u2013power athletes may require a broader, multifactorial approach beyond nutritional education alone.<\/jats:p>","DOI":"10.3390\/nu18091322","type":"journal-article","created":{"date-parts":[[2026,4,22]],"date-time":"2026-04-22T13:44:33Z","timestamp":1776865473000},"page":"1322","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sleep Quality, Dietary Patterns, and Nutrition Knowledge in Ultramarathon Runners and American Football Players: A Comparative Cross-Sectional Study"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2075-5438","authenticated-orcid":false,"given":"Aureliusz Andrzej","family":"Kosendiak","sequence":"first","affiliation":[{"name":"College of Health Studies, University of Lower Silesia, 53-611 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0930-3334","authenticated-orcid":false,"given":"Bartosz","family":"Colinso","sequence":"additional","affiliation":[{"name":"Medical Faculty, Wroclaw Medical University, 50-345 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0399-929X","authenticated-orcid":false,"given":"Zofia","family":"Ku\u017anik","sequence":"additional","affiliation":[{"name":"Medical Faculty, Wroclaw Medical University, 50-345 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5027-2713","authenticated-orcid":false,"given":"Szymon","family":"Makles","sequence":"additional","affiliation":[{"name":"Medical Faculty, Wroclaw Medical University, 50-345 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7699-5309","authenticated-orcid":false,"given":"Hanna","family":"Bazan","sequence":"additional","affiliation":[{"name":"Medical Faculty, Wroclaw Medical University, 50-345 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9874-6827","authenticated-orcid":false,"given":"Weronika","family":"Hariasz","sequence":"additional","affiliation":[{"name":"Medical Faculty, University of Opole, 45-040 Opole, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4675-5017","authenticated-orcid":false,"given":"El\u017cbieta","family":"Biernat","sequence":"additional","affiliation":[{"name":"Tourism Economy Research Unit, Institute of International Economic Policy, Collegium of World Economy, SGH Warsaw School of Economics, 02-554 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,22]]},"reference":[{"key":"ref_1","first-page":"543","article-title":"American College of Sports Medicine Joint Position Statement.
