Understanding its effects on post-match recovery and performance is crucial for optimizing training and competition strategies. Methods Eighteen male amateur soccer players (25.5 ± 3.2 years) from a regional club in southern Algeria were evaluated before, during, and after Ramadan. Blood biomarkers—including creatine kinase (CK), C-reactive protein (CRP), red and white blood cells (RBCs, WBCs), hemoglobin (HGB), hematocrit (HCT), and platelets (PLTs)—were measured. Physical performance was assessed using the Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IR1), countermovement jump (CMJ), and 20 m sprint tests. Repeated-measures ANOVA and Friedman tests were used to detect differences across periods (p < 0.05). Results Significant reductions in CRP, WBCs, PLTs, HGB, and CK were observed during Ramadan compared with pre- and post-fasting periods, whereas HCT and RBCs remained stable. Yo-Yo IR1 performance declined significantly during Ramadan, while CMJ and sprint performance showed no significant changes. These findings indicate a selective reduction in aerobic capacity with maintenance of anaerobic and explosive performance. Conclusions Ramadan fasting induces measurable alterations in inflammatory, hematological, and muscle-damage markers among soccer players in hot desert conditions. Although aerobic performance is compromised, short-duration and power-based efforts remain unaffected. Tailored hydration, nutrition, and training strategies are recommended to support athlete recovery and performance during Ramadan.

Blood biomarkers\u0026mdash;including creatine kinase (CK), C-reactive protein (CRP), red and white blood cells (RBCs, WBCs), hemoglobin (HGB), hematocrit (HCT), and platelets (PLTs)\u0026mdash;were measured. Physical performance was assessed using the Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IR1), countermovement jump (CMJ), and 20 m sprint tests. Repeated-measures ANOVA and Friedman tests were used to detect differences across periods (p\u0026thinsp;\u0026lt;\u0026thinsp;0.05).\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eSignificant reductions in CRP, WBCs, PLTs, HGB, and CK were observed during Ramadan compared with pre- and post-fasting periods, whereas HCT and RBCs remained stable. Yo-Yo IR1 performance declined significantly during Ramadan, while CMJ and sprint performance showed no significant changes. These findings indicate a selective reduction in aerobic capacity with maintenance of anaerobic and explosive performance.\u003c/p\u003e\u003ch2\u003eConclusions\u003c/h2\u003e \u003cp\u003eRamadan fasting induces measurable alterations in inflammatory, hematological, and muscle-damage markers among soccer players in hot desert conditions. Although aerobic performance is compromised, short-duration and power-based efforts remain unaffected. Tailored hydration, nutrition, and training strategies are recommended to support athlete recovery and performance during Ramadan.\u003c/p\u003e","manuscriptTitle":"Post-Match Changes in Biomarkers and Fatigue-Related Physical Performance Parameters in Young Amateur Soccer Players: The Effects of Fasting","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-12-18 19:12:41","doi":"10.21203/rs.3.rs-7918040/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2026-01-20T12:08:21+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-01-04T02:46:26+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-12-31T20:07:27+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"72642025261740537763303731152160745282","date":"2025-12-24T13:56:03+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"23043986454708021783822554760818570137","date":"2025-12-22T12:15:10+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"119912041445490464557148193220506626478","date":"2025-12-15T12:02:32+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-12-15T11:49:26+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-12-08T22:28:59+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2025-11-12T16:59:11+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-11-11T22:28:42+00:00","index":"","fulltext":""},{"type":"submitted","content":"BMC Sports Science, Medicine and Rehabilitation","date":"2025-11-11T22:26:03+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"bmc-sports-science-medicine-and-rehabilitation","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"ssmr","sideBox":"Learn more about [BMC Sports Science, Medicine and Rehabilitation](http://bmcsportsscimedrehabil.biomedcentral.com/)","snPcode":"","submissionUrl":"https://www.editorialmanager.com/ssmr/default.aspx","title":"BMC Sports Science, Medicine and Rehabilitation","twitterHandle":"BMC_series","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"em","reportingPortfolio":"BMC Series","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"c1cae9d3-05ea-4bc8-81d7-24c88ade69d6","owner":[],"postedDate":"December 18th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2026-03-30T16:18:30+00:00","versionOfRecord":{"articleIdentity":"rs-7918040","link":"https://doi.org/10.1186/s13102-026-01642-8","journal":{"identity":"bmc-sports-science-medicine-and-rehabilitation","isVorOnly":false,"title":"BMC Sports Science, Medicine and Rehabilitation"},"publishedOn":"2026-03-27 16:11:25","publishedOnDateReadable":"March 27th, 2026"},"versionCreatedAt":"2025-12-18 19:12:41","video":"","vorDoi":"10.1186/s13102-026-01642-8","vorDoiUrl":"https://doi.org/10.1186/s13102-026-01642-8","workflowStages":[]},"version":"v1","identity":"rs-7918040","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7918040","identity":"rs-7918040","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
