No effect of coactivation on fatigue-induced decreases in isokinetic and isometric torque in healthy young male adults

Eccentric exercise-induced muscle weakness abolishes sex differences in fatigability during sustained submaximal isometric contractions

“…It has been suggested that antagonist activation may contribute to fatigue-induced decreases in torque production. 57 Indeed, increases in antagonist activation during dynamic and isometric fatiguing tasks have been widely reported 57 for submaximal 55 , 58 , 59 and maximal 59 isometric contractions. The level of antagonist activation may also depend on muscle length such that there is an increase in antagonist activation at longer muscle lengths due to the joint being more susceptible to injuries such as hyperextension.…”
