In the early 90s, Charles R. Poliquin was asked what he thought the most significant advancement would be in strength coaching in the coming years. His reply: "Eccentric Training!"
The Strength Sensei defined eccentric strength as "the amount of force that is produced when a muscle lengthens vs. concentric strength which is the amount of force produced when a muscle shortens." He also cited research that said an eccentric contraction can produce as much as 1.3 times more force than a concentric contraction.
[Griffin, J. W. Differences in elbow flexion torque measured concentrically, eccentrically, and isometrically.Physical Therapy and Rehabilitation Journal. 67(8):1205-1208. 1 August 1987. Although this study involved 30 women and no men, subsequent research and empirical evidence supports the SS’s opinion that any athlete, male or female, can produce more force with eccentric contractions.]
