Studies investigating ECC only vs. CON only RT and the contribution to the increase in muscle girth within a young healthy population.

Studies	Population & muscle group	Intensity/duration	Matching	Results	Interpretation
Komi and Buskirk, 1972	Young—Elbow Flexors	MVC—7 Wks	No	ECC only increase	Muscle Girth: ECC> CONC in 2 studies (elbow flexors, pectoralis major). Similar responses in 2 out of 4 studies using Isokinetic or Isotonic loading
Duncan et al., 1989	Young men—Quadriceps	MVC—6 Wks	No	No sig changes for ECC and CON
Ben-Sira et al., 1995	Young women—Quadriceps	65% 1RM CON—10 Wks	No	Similar ECC and CON increase
Coratella and Schena, 2016 (*)	Young men—Pectoralis Major	CON = 85% 1RM, ECC = 120% CON 1RM—6 wks	Matched for load and training volume	ECC only increase
