Effects of Eccentric Exercise with Synergist Muscles on Muscle Activity, Muscle Tone, and Strength of the Hamstring Muscle

PURPOSE: This study aimed to investigate the effects of eccentric hamstring exercises accompanied by synergist muscle activation on muscle activity, muscle tone, and muscle strength.Although eccentric exercises are known to enhance muscle performance, the contribution of synergist activation to functional outcomes remains insufficiently understood.METHODS: Thirty healthy university students were randomly assigned to three groups: a concentric exercise group (CEG), an eccentric exercise group (EEG), and an eccentric exercise with synergist muscle group (SEG).
