Simultaneous Hoffmann reflex measurements in multiple muscles around the ankle.
Measurement of the Hoffmann reflex (H-reflex) provides an estimate of alpha motoneuron activity in the target motoneuron (MN) pool. The H-reflex has been assessed for a wide variety of reasons in neuroscience research. However, the majority of protocols have focused on the assessment of only one muscle and its corresponding motoneuron pool at any instant. Previously established protocols do not...
متن کاملPassive resistive torque of the plantar flexors following eccentric loading as assessed by isokinetic dynamometry.
Isokinetic dynamometers may provide a useful means of measuring muscle stiffness resulting from eccentric exercise because they can measure torque from computer-controlled passive movements of joints (passive resistive torque; PRT). In this study, a Biodex measured increased ankle PRT (52%; p <.001) following heel drop exercise in nine young women. Therefore, isokinetic dynamometers can provide...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Acute effect of muscle stretching on the steadiness of sustained submaximal contractions of the plantar flexor muscles.
This paper examines the acute effect of a bout of static stretches on torque fluctuation during an isometric torque-matching task that required subjects to sustain isometric contractions as steady as possible with the plantar flexor muscles at four intensities (5, 10, 15, and 20% of maximum) for 20 s. The stretching bout comprised five 60-s passive stretches, separated by 10-s rest. During the ...
متن کاملEffects of Plantar Flexor Muscles Fatigue on Postural Control during Quiet Stance and External Perturbation in Healthy Subjects
Background: The maintenance of postural control is a key component in dynamic physical activity, especially during muscle fatigue and against external forces. Despite many studies in this field, there is no consensus regarding the effects of plantar flexor muscles fatigue on postural control during different postural tasks.Objective: To evaluate the effects of plantar flexor muscles fatigue on ...
