The current study compared the acute inflammatory response and the relationship to mood following two intensities of high‐intensity interval exercise ( HIIE ). Eight physically active males (25 ± 6 years;V ˙ O 2 max49.02 ± 5.53 mL·kg −1 ·min −1 ) undertook two 20‐minute HIIE trials (10 × 1‐minute intervals at 80% ( HIIE 80) and 90% ( HIIE 90)V ˙ O 2 maxinterspersed with 1‐minute active recovery). Plasma interleukin‐6 ( IL ‐6), leukocyte counts, and Brunel Mood Scale ( BRUMS ) mood ratings were collected before (pre), immediately after (post), 30 minutes (post30) and 60 minutes (post60) post‐exercise with an additional measure of mood 24 hours post‐exercise (post24 h). Feelings of tension were significantly reduced post30 ( P = 0.003), post60 ( P = 0.001) and post24 h ( P = 0.01) following HIIE 80. Correlations between IL ‐6 and mood identified a significant negative relationship between IL ‐6 and fatigue 30 minutes after HIIE 80 ( r = −0.78, P = 0.02). Inflammatory response did not significantly differ between exercise intensities; however, only HIIE 90 was sufficient to elicit a significant transient increase in IL ‐6 (2.64‐fold) which may provide an effective strategy to target inflammatory dysregulation. Future studies are required to establish the long‐term implications of the anti‐inflammatory properties of HIIE on mood.
