Eccentric Exercise and Metabolism

By Aaron Bubbico, B.S. and Len Kravitz, Ph.D., March 25, 2014

The source material listed below is interesting, but it’s also a rather long, dry academic article. If you have a particular interest in Eccentric Exercise, and would like to understand it better from the molecular level up, it’s worth a look. It’s also a good information resource regarding “exercise-induced delayed onset muscle soreness” or “DOMS,” if you’re wondering why people tend to ache the day after a heavy workout.


“Research has found that doing exercise with an eccentric emphasis can acutely and meaningfully raise the resting energy expenditure of both untrained and trained individuals after a total body workout (Hackney et al., 2008). Hackney and colleagues found that performing one full-body workout with an eccentric emphasis (1 second concentric and 3 second eccentric on all exercises) elevated resting energy expenditure approimately 9% after the workout. The resting energy expenditure from resistance exercise is likely caused by recovery and repair factors associated with DOMS, the overall muscle repair process and the energy costs associated with protein synthesis. (Hackney et al, 2008).”
