Duchenne muscular dystrophy is clinically characterised by progressive muscle weakness and a gradual increase in the size of some affected muscles, especially calf muscles. The extent of calf enlargement is usually determined by subjective visual assessment. The purpose of this study was to determine the extent of calf muscle enlargement in Duchenne muscular dystrophy (DMD) patients compared wi...

People come in different shapes and sizes. In particular, calf muscle size in humans varies considerably. One possible cause for the different shapes of calf muscles is the inherent difference in neural signals sent to these muscles during walking. In sedentary adults, the variability in neural control of the calf muscles was examined with muscle size, walking kinematics and limb morphometrics....

A study has been made of the isometric twitches of hypothenar and calf muscles in man. The twitch contraction time for hypothenar muscles ranged between 55 78 ms, while for the calf muscles it ranged between 90 and 125 ms. According to their speed of contractions the hypothenar muscles were considered belonging to the so called intermedious group while the calf muscles integrate the slow group....

black leg has been reported in a variety of animals, but is ofthe most importance in cattle and sheep. a20 days old holsteindairy calf was examined because of anorexia and lameness from2 days ago. the calf was depressed, tachypneic, tachycardic, andhad a body temperature of 38.5ºc. both hind limbs proximal tothe tarsal joint were markedly swollen, firm and painful. nocrepitation was noted on pa...

The main purpose of this study was to determine and compare extra- and intramyocellular (IMCL) lipids content in the calf and thigh muscles of normal male and female volunteers using high-spatial-resolution magnetic resonance spectroscopic imaging (MRSI). The study groups consisted of 10 females and 10 males. The subjects were healthy and normal-weight. Fat (yellow bone marrow) was used as the ...

The loss of muscle mass with aging and consequent weakness results in compensatory gait motions. Although these motions increase the cost walking, they appear to be an attempt by elderly maintain safe ambulation. However, relationship between affected muscles cycle is unclear. This study examined compensation young subjects whose were weakened Muscle Activity Restriction Taping Technique, which...

In this paper we report investigations of the innervation of duplicated limb segments to test whether the addition of limb segments along the proximodistal axons could stimulate the growth of appropriate motoneurons into double occurrences of these muscles. Our evidence indicates that it does not. Using retrograde horseradish peroxidase nerve-tracing techniques and reconstructions of experiment...

background: the aim of this study is to verify the effects of the combined and classic training of different isometric rates of force development (rfd) parameters of legs. materials and methods: three groups of female athletes was tested: experimental group (n = 12), classically trained group (n = 11), and control group (n = 20) of athletes. the isometric “standing leg extension” and “ris...

Depletion of muscle glycogen is considered a limiting performance factor during prolonged exercise, whereas the role of the intramyocellular lipid (IMCL) pool is not yet fully understood. We examined 1) intramyocellular glycogen and lipid utilization during prolonged exercise, 2) resynthesis of muscle glycogen and lipids during recovery, and 3) changes in glycogen content between nonexercising ...
