The aim of the present study was to devise a non-damaging high-inten-sity intermittent running protocol. Ten healthy active men completed high-intensity interval running (8×3-min bouts at 90% of maximal oxy-gen uptake interspersed with 3-min recovery) on a motorized treadmill under normal laboratory temperatures. Mean heart rate and rating of perceived exertion significantly increased during the intermittent proto-col (the first bout, 15.3±1.2; the final bout, 18.6±0.9; P<0.001). Blood lactate concentrations were significantly elevated following bout 1 compared with resting values (1.2±0.3 mmol/L vs 5.4±2.4 mmol/L; P=0.03). However, no significant reduction in maximal voluntary con-traction was observed immediately after completing the last exercise bout (623.9±143.6 N) or during the subsequent 7-d period compared to pre-exercise values (P=0.59). Creatine kinase (CK) concentrations were not significantly increased following exercise or during the subse-quent 7-d period (P=0.96). Myoglobin (Mb) content was significantly in-creased following exercise (P=0.01), however, values returned towards pre-exercise concentrations after 24 h. These results indicate that the high-intensity intermittent running protocol induced changes in physio-logical and subjective indices that are consistent with the effects of acute fatigue as opposed to those changes normally associated with exercise-induced muscle damage. This exercise protocol can therefore be used to investigate the influence of high-intensity exercise from physiological responses to molecular adaptation.
