Neuromotor Mechanisms Involved in the Recovery from Local Muscular Fatigue
… and surface electromyography (sEMG) from the tibialis anterior and soleus were monitored concurrently. Following the two fatigue conditions (10 and 20% force decrement) force recovered to 100.5 and 99.5% of initial levels for each condition, respectively. Surface EMG root-mean-square amplitude …

Neuromuscular Ultrasound as a Biomarker of Disease Progression in ALS
… four muscle groups including the biceps brachii, tibialis anterior, geniohyoid, and hemi-diaphragm at both inhalation and exhalation. We measured three times over six months and found significant changes. All muscle groups showed an expected decrease in thickness. When the percentage decline of …

Gene expression profiling of myostatin null mice
… associated with each of these processes in the tibialis anterior, gastrocnemius, and soleus muscles. Additionally, creatine content and creatine kinase (CK) activity was directly measured in the tibialis anterior and gastrocnemius muscles. Expression of nearly all genes investigated was …

The Influence of Occupational Footwear on Slip Responses
… the left (slip limb) medial hamstrings and left tibialis anterior as well as 2˚ less plantar-flexion after encountering the slip. The OF group also activated their right (non-slip) tibialis anterior, medial gastrocnemius, and vastus lateralis to a lesser extent, by 66-78%, after the slip onset. …

Risk factors for Achilles tendinopathy in runners - an investigation of selected intrinsic, kinematic, kinetic and muscle activity factors that are associated with Achilles tendinopathy
… integrated electromyography activity (IEMG) of tibialis anterior and rectus femoris in the AT group during the running cycle. Stride to stride variability was similar between UN and AT runners but the biomechanics variability between participants were lower for the AT runners. No specific …

Lower limb muscle function during cycling.
… vastus lateralis, soleus, gastrocnemius, and tibialis anterior muscles during stationary cycling at 160 W (90 r/min). The results showed that extension during the propulsive phase of the pedal cycle was the result of high concentric activity of both the monoarticular and biarticular muscles. …

The effect of dietary creatine supplementation on compensatory muscle hypertrophy and performance characteristics of specific fiber types
… were surgical controls, two groups had the tibialis anterior ablated, to hypertrophy the extensor digitorum longus (EDL), and two groups the gastrocnemius and the plantaris ablated, to hypertrophy the soleus. One of each of these groups had their diet supplemented with creatine monohydrate. …

Impacts of Empagliflozin (EMPA) Treatment on Skeletal Muscle Microvasculature in Type 1 Diabetic Rats
… not impacted by EMPA+insulin treatment in the tibialis anterior. PECAM mRNA and VEGFa protein expression was also not impacted by EMPA+insulin treatment. EMPA has no obvious impact on the vasculature of SM in type 1 diabetic rodents.

Characteristics of muscle activation patterns at the ankle in stroke patients during walking.
… envelope. Patients with common patterns of tibialis anterior activity did not necessarily share common patterns of gastrocnemius or soleus activity. Patients with similar linear envelope patterns did not always present with the same kinematic profiles. The relationship between observable …

Ankle mechanical impedance under muscle fatigue
… experiment was designed to induce fatigue in the tibialis anterior and triceps surae muscle groups by instructing subjects to perform isometric contractions against a constant ankle torque generated by a backdrivable robot, Anklebot, which interacts with the ankle in two degrees of freedom. Median …

Green tea extract and epigallocatechin gallate decrease muscle pathology and NF-κB immunostaining in regenerating muscle fibers of mdx mice
… at age 42 days. Normal fiber morphology in the tibialis anterior muscle was increased by 32% at this age (P≤0.05). The primary histopathological change was a 21% decrease in regenerating fibers (P≤0.05). NF-κB staining in central nuclei of regenerating fibers was decreased by 34% (P≤0.05). In …

The impact of primary motor cortex, spinal cord, and sciatic nerve cooling on spinal reflex activity in the rat: a reversible deactivation study
… rat, recording electrodes were placed in the tibialis anterior muscle of the hindlimb to record both the direct muscle response (M-wave) and the muscle reflex response (H-wave) in response to electrical stimulation of the sciatic nerve. After baseline recordings, thermal deactivation was used …

Modeling Gait Muscle-Reflexes Through Hindlimb Characterization in Rodents
… works could explore a similar paradigm in the tibialis anterior muscle, an antagonist to the medial gastrocnemius muscle, and explore higher order nonlinear muscle-reflex models.

Decreased Peak Muscle Power is Associated with Motor Unit Loss in the Lower Limb of Older Adults
… 24 ± 3 yrs) were studied. MU properties of the tibialis anterior (TA) and vastus medialis (VM) muscles were determined using decomposition-enhanced spike-triggered averaging (DE-STA). Motor unit number estimates (MUNE) of the TA were significantly reduced (p>0.05) in older adults (102 ± 76) …

The surface electromyography-force relationship during isometric dorsiflexion in males and females
… study evaluated sex-related differences in the tibialis anterior (TA) surface electromyography (EMG) to force relationship. One-hundred participants (50 males and 50 females) performed three isometric contractions at 20, 40, 60, 80, and 100% of maximal voluntary contraction (MVC) in an apparatus …

The effect of localized muscle fatigue on tibial impact acceleration.
… the acceleration/time curve. EMG activity of the tibialis anterior and gastrocnemius was used to define and monitor fatigue. The dorsiflexors and plantarflexors were fatigued on two separate days, at least a week apart. Statistical analysis revealed a significant decrease in peak acceleration and …

Sphingolipids Modulate the Inflammatory and Functional Response in mdx Mice
… contractile properties in vitro were determined; Tibialis Anterior (TA) inflammatory markers were profiled by qRT-PCR; TA sections were stained with H&E and immunohistochemistry for p-Akt was performed. At age 9 weeks, in vivo ankle flexor torque at stimulation frequencies 50-150 Hz was greater in …

THE EFFECT OF SDF1α ON SKELETAL MUSCLE REGENERATION AFTER COMPARTMENT SYNDROME INJURY
… , or SC treatment was injected into the injured tibialis anterior (TA) muscle. In vivo muscle function (isometric torque) was determined prior to injury and 7 and 14 days after injury via stimulation of the peroneal nerve. Histological assessments and qPCR were used to determine the tissue and …
