Eccentric and Concentric Strength Differences in Men and Women

Endocrine alterations from concentric vs. eccentric muscle actions: A brief review

“…Resistance training is usually performed with CON and ECC contractions at the same, constant load. Due to effects of gravity and connective tissue properties, an individual can complete an eccentric [ECC] muscle contraction with a greater load than can be lifted using a concentric [CON] contraction [12,13]. As such, fewer motor units are recruited during ECC contractions compared with equally loaded CON contractions [14], which is attributed to the greater economical generation of tension during ECC muscle actions [14].…”
