We examined the acute effect of concentric and muscle-damaging eccentric exercise, matched for intensity, on the responses to a 2-hr 75-g oral glucose tolerance test (OGTT). Ten men (27 \u00b1 9 years, 178 \u00b1 7 cm, 75 \u00b1 11 kg, VO<jats:sub>2<\/jats:sub>max: 52.3 \u00b1 7.3 ml\u00b7kg<jats:sup>-1<\/jats:sup>\u00b7min<jats:sup>-1<\/jats:sup>) underwent three OGTTs after an overnight 12 hr fast: rest (control), 40-min (5 \u00d7 8-min with 2-min interbout rest) of concentric (level running, 0%, CON) or eccentric exercise (downhill running, \u201312%, ECC). Running intensity was matched at 60% of maximal metabolic equivalent. Maximal isometric force of <jats:italic>m. quadriceps femoris<\/jats:italic> of both legs was measured before and after the running protocols. Downhill running speed was higher (level: 9.7 \u00b1 2.1, downhill: 13.8 \u00b1 3.2 km\u00b7hr<jats:sup>-1<\/jats:sup>, <jats:italic>p<\/jats:italic> &lt; .01). Running protocols had similar VO<jats:sub>2<\/jats:sub>max (<jats:italic>p<\/jats:italic> = .59), heart rates (<jats:italic>p<\/jats:italic> = .20) and respiratory exchange ratio values (<jats:italic>p<\/jats:italic> = .74) indicating matched intensity and metabolic demands. Downhill running resulted in higher isometric force deficits (level: 3.0 \u00b1 6.7, downhill: 17.1 \u00b1 7.3%, <jats:italic>p<\/jats:italic> &lt; .01). During OGTTs, area-under-the-curve for plasma glucose (control: 724 \u00b1 97, CON: 710 \u00b1 77, ECC: 726 \u00b1 72 mmol\u00b7L<jats:sup>-1<\/jats:sup>\u00b7120 min, <jats:italic>p<\/jats:italic> = .86) and insulin (control: 24995 \u00b1 11229, CON: 23319 \u00b1 10417, ECC: 21842 \u00b1 10171 pmol\u00b7L<jats:sup>-1<\/jats:sup>\u00b7120 min, <jats:italic>p<\/jats:italic> = .48), peak glucose (control: 8.1 \u00b1 1.3, CON: 7.7 \u00b1 1.2, ECC: 7.7 \u00b1 1.1 mmol\u00b7L<jats:sup>-1<\/jats:sup>, <jats:italic>p<\/jats:italic> = .63) and peak insulin levels (control: 361 \u00b1 188, CON: 322 \u00b1 179, ECC: 299 \u00b1 152 pmol\u00b7L<jats:sup>-1<\/jats:sup>, <jats:italic>p<\/jats:italic> = .30) were similar.
