Effects of Concentric and Eccentric Strength Training on Electromyography Activity of the Knee Agonist –Antagonist Muscle
Purpose: An appropriate activity of the knee agonist -antagonist muscles is important to resist against abnormal abduction-adduction moments loads around knee joint and reduce the risk of knee injuries. Exercise training has been commonly used as an intervention to improve neuromuscular activity within the synergic and/or agonist-antagonist muscles. However, maximizing the effectiveness of exer...
متن کاملGreater initial adaptations to submaximal muscle lengthening than maximal shortening.
The purpose of this study was to compare the short-term strength and neural adaptations to eccentric and concentric training at equal force levels. Forty-two sedentary women (age = 21.5 yr) were ranked based on the initial quadriceps strength score, and trios of subjects were randomly assigned to either an eccentric (n = 14), a concentric (n = 14), or a nonexercising control group (n = 14). Tra...
متن کاملEffect of eccentric strengthening after anterior cruciate ligament reconstruction on quadriceps strength.
CLINICAL SCENARIO Interventions aimed at safely overloading the quadriceps muscle after anterior cruciate ligament (ACL) reconstruction are essential to reducing quadriceps muscle weakness that often persists long after the rehabilitation period. Despite the best efforts of clinicians and researchers to improve ACL rehabilitation techniques, a universally effective intervention to restore prein...
متن کاملEarly application of negative work via eccentric ergometry following anterior cruciate ligament reconstruction: a case report.
STUDY DESIGN Case report. OBJECTIVES To present a progressively increasing negative-work exercise program via eccentric ergometry early after anterior cruciate ligament reconstruction (ACL-R) and to suggest the potential of negative work to amplify the return of quadriceps size and strength. CASE DESCRIPTION The patient was a 26-year-old highly active recreational athlete who sustained an A...
متن کاملNeural inhibition during maximal eccentric and concentric quadriceps contraction: effects of resistance training.
Despite full voluntary effort, neuromuscular activation of the quadriceps femoris muscle appears inhibited during slow concentric and eccentric contractions. Our aim was to compare neuromuscular activation during maximal voluntary concentric and eccentric quadriceps contractions, hypothesizing that inhibition of neuromuscular activation diminishes with resistance training. In 15 men, pretrainin...
