The First Systematic Review on Eccentric vs Concentric Training and Muscle Strength

What’s This Research About?

Is eccentric training better for building strength? Previous research suggests eccentric muscle actions differ from concentric muscle actions. Mechanically, eccentric muscle contraction leads to greater force production when compared to concentric muscle contractions. This preliminary research has lead researchers to speculate that eccentric resistance training could stimulate greater adaptations than concentric resistance training.

Even though previous research examined the differences between the two types of resistance training, there had not been a systematic review of the literature summarizing the findings or the scientific validity of the research. In this systematic review researchers hoped that by performing a review of the literature, they could determine if eccentric training is superior to concentric training in stimulating gains in muscle mass.

TITLE: The Effects of Eccentric Versus Concentric Resistance Training on Muscle Strength and Mass in Healthy Adults: A Systematic Review with Meta-analysis


PUBLICATION: British Journal of Sports Medicine

DATE: 2009

AUTHORS: M. Roig, K O’Brien, G. Kirk, R. Murray, P. McKinnon, B. Shadgan, and W.D. Reid

Concentric Exercise: An exercise that emphasizes production of force while a muscle is shortening.

Eccentric Exercise: An exercise that emphasizes production of force while a muscle is lengthening.

Force: A push or pull that has both magnitude or direction and causes an object with mass to change its velocity.

Meta-analysis: An analysis that uses statistical methods to summarize the results of a group of studies.

Systematic Review: An analysis that answers a defined research question by collecting and summarizing all empirical evidence that fits pre-specified eligibility criteria.

About the Author:

Jenn Pilotti has a BS in exercise physiology from UC Davis. After graduating in 2002, she was hired by the Beach and Tennis Club at Pebble Beach as a full time personal trainer. While there, she had the privilege of working with individuals of all ages, many of whom had aches and pains from a life well led. This piqued her interest in injuries, prevention, and pain. After years of undirected self study (and after leaving the security of a full time position to go out on her own), she enrolled in an online program through AT Still University, eventually acquiring a master's in human movement while working full time. After graduating, she continued to read research and write about its application to her work with clients. She fell in love with yoga in 2004, finally became 200 hour RYT in 2014 after years of workshops and self study (there seems to a theme), and continues to study somatic disciplines. She is DNS exercise trainer certified, FRCms, MovNat level I certified, GMB trainer certified, has taken PRI respiration, myokinematics, impingement and instability, and pelvis restoration, and has read an embarrassing number of books on movement, psychology, and wellness. She has an insatiable curiosity about what makes for a healthy person, physically and mentally, and she finds herself often asking why things work for some and not for others. She strongly believes in the power of knowledge and the power of movement. Learn more about Jenn Pilotti.
