Background and objectives: The role of genetic components in expression of proteins involved in signaling pathways of fat and carbohydrate metabolism has been well-demonstrated. The aim of this study was to determine effects of high intensity interval training (HIIT) on glucose, insulin, and insulin resistance levels as well as IRS1 expression in gastrocnemius muscle of obese Wistar rats. Meth...

Purpose: Many patients with Achilles Tendinopathy do not respond to eccentric training. The aim of the present case report is to find out the effect of eccentric concentric training of gastrocnemius and soleus combined with isometric contraction of gastrocnemius and static stretching exercises of gastrocnemius and soleus on pain and disability in a patient experiencing Achilles Tendinopathy. Me...

BACKGROUND The Achilles tendon is composed of fascicles from the soleus and gastrocnemius muscles, which are identifiable as discrete components at anatomical dissection. HYPOTHESIS The pattern of fascicular involvement in Achilles tendinopathy may be characterized at ultrasound, and this characterization is reliable between different observers. STUDY DESIGN Cross-sectional diagnostic study...

January/February 2005 • Vol 95 • No 1 • Journal of the American Podiatric Medical Association Equinus deformity is defined as a limitation of dorsiflexion motion of the ankle joint. Although many authors have attempted to specify the necessary degrees of ankle dorsiflexion, normative values have been limited.1, 2 Biomechanically, the maximum amount of dorsiflexion in the stance phase of normal ...

A bilateral gastrocnemius tertius muscle and a unilateral accessory soleus muscle were encountered during the routine educational dissection studies. The right gastrocnemius tertius muscle consisted of one belly, but the left one of two bellies. On the left side, the superficial belly of the gastrocnemius tertius muscle had its origin from an area just above the tendon of the plantaris muscle, ...

Distinguishing gastrocnemius and soleus muscle function is relevant for treating gait disorders in which abnormal plantarflexor activity may contribute to pathological movement patterns. Our objective was to use experimental and computational analysis to determine the influence of gastrocnemius and soleus activity on lower limb movement, and determine if anatomical variability of the gastrocnem...

Several authors have shown different excitation patterns for soleus and gastrocnemius muscles in response to cadence manipulation during cycling. The purpose of this study was to examine gastrocnemius and soleus length and velocity change as a function of pedalling cadence to consider mechanisms underlying these excitation differences. Ten male and two female cyclists rode at five randomly assi...

BACKGROUND Gastrocnemius recession is performed to correct an isolated gastrocnemius equinus contracture of the ankle that may accompany foot and ankle pathology in the adult. It has been proposed that this equinus deformity leads to excessive strain throughout the foot, thus causing pain. This can manifest itself in the form of plantar fasciitis, metatarsalgia, posterior tibial tendon insuffic...

The effect of zinc was studied on isolated frog gastrocnemius muscle wich stimulated directly or indirectly and perfused with Ringer containing calcium(Ca2+) deplated Ca2 +. N.ischiadicus-gastrocnemius muscles were obtained from 15 frogs. Isometric force generated in response to supramaximal electrical stimulation measured a transducer peak tension(Pt), contraction time(CT) total time(TCT) anal...
