Whether PFO increases from PS to competitive season (CS) in elite male football players remains unknown. This study investigated if PFO increases from PS to CS in elite male football players, and secondarily, it explored the interplay between PFO and running performance. Twenty\u2010two elite male outfield football players reported to the laboratory during PS and CS. Testing included a resting blood sample, a dual\u2010energy X\u2010ray absorptiometry scan, and a graded treadmill running test. The players' load during training and matches was monitored between the test days. PFO, the intensity eliciting PFO (Fatmax) and peak oxygen consumption (V\u0307O\n                    <jats:sub>2<\/jats:sub>\n                    peak) did not change from PS to CS (mean difference with 95% confidence intervals: \u22121.0\u2009mg\u00b7kg FFM\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u00b7min\n                    <jats:sup>\u22121<\/jats:sup>\n                    (95% CI: \u22122.4 to 0.3\u2009mg\u00b7kg FFM\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u00b7min\n                    <jats:sup>\u22121<\/jats:sup>\n                    ), 1% V\u0307O\n                    <jats:sub>2<\/jats:sub>\n                    peak (95% CI: \u22124% to 6% V\u0307O\n                    <jats:sub>2<\/jats:sub>\n                    peak) and 0.2\u2009mL\u00b7kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u00b7min\n                    <jats:sup>\u22121<\/jats:sup>\n                    (95% CI: \u22121.0 to 1.4\u2009mL\u00b7kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u00b7min\n                    <jats:sup>\u22121<\/jats:sup>\n                    ), respectively).
