Considerations for Improving Triceps Surae Flexibility
Strength & Conditioning Journal, 2015Triceps surae flexibility exercises are routinely prescribed as a component of lower extremity fitness and rehabilitation programs. Flexibility deficits, addressed without consideration of hindfoot position, may be associated with and perpetuate foot and ankle pain.

Menstrual cycle variation and gender difference in muscle stiffness of triceps surae
Clinical Biomechanics, 2019Background: We aimed to investigate the menstrual cycle variation and the gender difference of the triceps surae muscle stiffness and passive stiffness of the ankle joint.

Synaptic terminal coverage of primate triceps surae motoneurons
Journal of Comparative Neurology, 1994AbstractThis study examined the synaptic terminal coverage of primate triceps surae (TS) motoneurons at the electron microscopic level. In three male pigtail macaques, motoneurons were labeled by retrograde transport of cholera toxin‐horseradish peroxidase that was injected into TS muscles bilaterally and visualized with tetramethylbenzidine stabilized

Cat triceps surae motor nuclei are organized topologically
Experimental Neurology, 1987A "compartment nucleus" consists of a group of spinal motoneurons that supply the individual primary branches of a muscle nerve. Each primary muscle nerve branch innervates a specific subvolume or compartment of a muscle. The spatial and size distributions of motoneurons supplying primary nerve branches of the cat medial gastrocnemius muscle were ...

Triceps surae force, length and velocity during walking
Gait & Posture, 2005Individuals with neuromuscular conditions may develop muscle contractures that limit joint motion. Decreased muscle length is clinically obvious, but deviations in other functional characteristics of muscle, such as underlying weakness or decreased shortening velocity are more obscure.

Changes in triceps surae muscle architecture with sarcopenia
Acta Physiologica Scandinavica, 2005AbstractAim: To investigate whether sarcopenia was evenly distributed among the three components of the triceps surae (TS) muscle group.Methods: Muscle volume (VOL), fibre fascicle length (Lf), pennation angle (θ) and physiological cross‐sectional area (PCSA = VOL/Lf) were measured in vivo for the lateral (GL) and medial (GM) heads of the ...

Interactions in human quadriceps-triceps surae motoneuron pathways
Experimental Brain Research, 1991In an effort to more fully investigate spinal reflex pathways in humans, we measured the isometric force-time curve of the patellar (PTR) and Achilles (ATR) tendon-tap reflex in 12 college age subjects. We also conditioned the tendon jerk with a contralateral or ipsilateral tendon-tap stimulus, to ascertain the effects of segmental inputs on crossed ...

Voluntary Inducement of Triceps Surae Muscle Cramping
International Journal of Athletic Therapy and Training, 2013Context:Exercise-associated muscle cramping (EAMC) is difficult to induce experimentally.Purpose:T o assess the reliability of a maximum voluntary contraction (MVC) procedure for inducement of a muscle cramp.Participants:Seventy-four healthy and physically active participants (23 ± 8 years of age; 49 males and 25 females); 63 who had previously ...

System identification of human triceps surae stretch reflex dynamics
Experimental Brain Research, 1983The interpretation of stretch-evoked reflex responses is complicated by the fact that the pattern of response will depend upon both the underlying reflex mechanisms and the time course of the stretch used to evoke the response. The objective of the present study was to use engineering systems analysis techniques to identify the dynamics of the human ...

Modulation of the Triceps Surae H-Reflex with Training
International Journal of Neuroscience, 1994Thirteen neurologically healthy adults were asked to balance on a specially designed balance board. This board allowed rotation in the sagittal plane only. Muscle activity of the triceps surae and tibialis anterior was sampled at 2 kHz and recorded. When the subject was balanced, soleus H-reflexes were elicited in the right leg with a constant-current ...
