The influence of strain and activation on the locomotor function of rat ankle extensor muscles.
The ankle extensor muscles of the rat have different mechanical and physiological properties, providing a means of studying how changes in locomotor demands influence muscle fascicle behaviour, force and mechanical power output in different populations of muscle fibre types. Muscle fascicle strain, strain rate and activation patterns in the soleus, plantaris and medial gastrocnemius muscles of ...
متن کاملIdentified ankle extensor and flexor motoneurons display different firing profiles in the neonatal rat.
The present study was designed to compare the firing profiles exhibited by lumbar flexor or extensor motoneurons in response to injection of depolarizing/repolarizing currents. Motoneurons were recorded intracellularly in the in vitro brainstem-spinal cord of newborn rats (P4-P7). They were synaptically isolated and identified by antidromic stimulations of the central stump of flexor or extenso...
متن کاملResponses of ankle extensor and flexor motoneurons to transcranial magnetic stimulation.
Transcranial magnetic stimulation (TMS) of the motor cortex excites limb muscles of the contralateral side of the body. Reports of poorly defined, or a complete lack of systematic excitatory responses of soleus motoneurons compared with those of tibialis anterior (TA) motoneurons has led to the proposal that while all ankle flexor motoneurons receive strong corticomotoneuronal connections, very...
متن کاملThe effect of knee extensor and ankle plantar flexor fatigue on dynamic balance in active elderly males
The purpose of this study was to examine the effect of knee extensor and ankle plantar flexor fatigue on dynamic balance among active elderly males. Fifteen healthy individuals having age of 72±6.57 years, height of 168.4±4.8 cm and weight of 70.5±7.4 kg without history of injuries at lower extremity, participated in this study. Knee extensor and ankle plantar flexor muscles fatigued with f...
متن کاملGroup I disynaptic excitation in flexor and bifunctional motoneurons during locomotion.
In the absence of locomotion, activation of extensor muscle spindle (Ia) and tendon organ (Ib) afferents evokes a widespread pattern of interneuronally mediated inhibition and excitation through the non-reciprocal reflex systems (1). During the extension phase of fictive locomotion, however, the same afferents evoke a disynaptic excitation of extensor motoneurons (2). Recently it has been repor...
