The effects of muscle damage on running economy in healthy males.
Int J Sports Med. 2005 Dec; 26(10):827-31.IJ

Abstract

Published information on aspects related to muscle damage and running economy is both limited and contradictory. To contribute to the current debate, we investigated the effects of an eccentric exercise session on selected muscle damage indices in relation to running economy using 10 (mean age 23 +/- 1 years) healthy male volunteers. The eccentric exercise session consisted of 120 (12 x 10) maximal voluntary repetitions by each randomly selected leg at the angular velocity of 1.05 rad . s (-1). Muscle damage (creatine kinase, delayed onset muscle soreness, range of movement, and eccentric, concentric and isometric [at 60 degrees and 110 degrees knee flexion] peak torque) and running economy (oxygen consumption, pulmonary ventilation, respiratory exchange ratio and breaths per minute during treadmill running at 133 and 200 m . min (-1)) indicators, were assessed pre-, 24-, 48-, 72- as well as 96-h after exercise. All muscle damage indicators revealed significant changes at almost all time-points of assessment compared to pre-exercise data (p < 0.05). However, none of the running economy parameters disclosed any significant change throughout the study (p > 0.05). It was concluded that changes in muscle damage and muscle performance as measured in this study are not reflected by concomitant alterations in running economy at submaximal intensities.
