Changes In Muscle Function And Motorneuron Excitability Of The Triceps Surae Following A Bout Of Fatiguing Eccentric Exercise, Mikala Pougnault

Theses : Honours

A reduction in capacity of the neuromuscular system associated with exercise can occur from a wide range of physiological and psychological factors. Many researchers have investigated neural activation during exercise, or the effects of muscle damage associated with eccentric exercise, but few have studied the prolonged effects of a bout of eccentric exercise on strength and motorneuron excitability. Eleven male and female subjects (aged 20-43 years) were tested to determine the effects of a fatiguing bout of eccentric exercise upon maximal isometric plantarflexion strength, motorneuron excitability, and neural activation of the soleus (SOL) and medial gastrocnemius (MG). The exercise consisted …
