Context: Contemporary wide variety of footwear is one the main reason for increased incidence Achilles Tendon Disorders (ATDs). Introduction: Flexed knee heel rise (FKHR) task exploited clinically to evaluate and rehabilitate Soleus (SOL) muscle. FKHR done in variable without considering its influence on muscles. Information lacking about leg muscles FKHR. This understanding vital clinical effi...

It has been shown that lipid peroxidation product levels in the soleus muscles of rats fed palm olein were lower than in the soleus muscles of rats fed soya bean oil. A study was carried out to test our hypothesis that the lower level of lipid peroxidation products in the soleus muscle of palm olein-fed rats is due, at least partly, to the higher amount of vitamin E in their soleus muscles. Exp...

[Purpose] To compared activation of the tibialis anterior and soleus muscles during the sit-to-stand movement in elderly people. [Subjects and Methods] Ten elderly women were enrolled. The activities of the dominant lower extremity muscles were measured using a wireless electromyography system. Subjects performed natural sit-to-stand tasks. [Results] In the pre-thigh off phase, the tibialis ant...

The consequences of two-week hindlimb suspension (HS) on skeletal muscle atrophy were investigated in balanced diet-fed Fat-1 transgenic and C57BL/6 wild-type mice. Body composition and gastrocnemius fatty acid composition were measured. Skeletal muscle force, cross-sectional area (CSA), and signaling pathways associated with protein synthesis (protein kinase B, Akt; ribosomal protein S6, S6, e...

A proteomic analysis was performed comparing normal rat soleus muscle to denervated soleus muscle at 0.5, 1, 2, 4, 6, 8 and 10 days post denervation. Muscle mass measurements demonstrated that the times of major mass changes occurred between 2 and 4 days post denervation. Proteomic analysis of the denervated soleus muscle during the atrophy process demonstrated statistically significant (at the...

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...

The effect of insulin resistance (IR) on the adaptation of skeletal muscle loading is not well understood. Here we examine whether the soleus muscles of the lean Zucker (LZ) and insulin-resistant obese Zucker (OZ) rat exhibit differences in their ability to undergo muscle hypertrophy following 8 wk of mechanical overload. Four-week-old male LZ (n = 5) and OZ (n = 5) rats underwent unilateral su...

1. Comparisons were made in vitro at 25 degrees C among soleus and extensor digitorum longus (EDL) muscles from young (2-3 months), adult (9-10 months), and aged (26-27 months) male mice. We tested the hypotheses that, compared with soleus and EDL muscles of young and adult mice, those from aged mice develop decreased maximum tetanic force (P0, mN) and specific P0 (N/cm2), and that no significa...
