[Purpose] This study attempted to identify how genu varum or valgum affects the electromyographic activities of the vastus medialis, vastus lateralis, and rectus femoris during knee isometric contraction. [Subjects] Fifty-two healthy young adults were enrolled in this study. They were enrolled and classified into three groups by knee alignment conditions: the genu varum, genu valgum, and contro...

Fish are cold-blooded vertebrates, whose body movements and balance mainly using fins, breathing through gills, living in an aquatic environment. Most vertebrates the world fish covering 48.1%, mammals (10.8%), reptiles (14.4%), amphibians (6.0%), birds (20.7%). One of consumed North Sulawesi is scad mackerel locally called malalugis. This research focused on meristic morphometric characteristi...

BACKGROUND Skeletal muscle dysfunction is a common feature in chronic obstructive pulmonary disease (COPD) which is associated with intrinsic muscular abnormalities. One of the most consistently reported alterations is a shift from fibre type I to II in the vastus lateralis of these patients. Surprisingly, the relationship between this shift and the severity and phenotype of COPD remains unclea...

Ancient DNA is becoming increasingly recognised as a tool in conservation biology to audit past biodiversity. The widespread loss of Australian biodiversity, especially endemic mammal populations, is of critical concern. An extreme example occurred onDepuch Island, situated off the north-west coast ofWestern Australia, where an unidentified species of rock-wallaby (Petrogale sp.) became extinct...

[Purpose] The purpose of this study was to investigate the difference in onset timing between the vastus medialis and lateralis among the different knee alignments, as well as the best isokinetic angular velocity for an isokinetic concentric contraction. [Subjects] Fifty-two adults (20 with genu varum, 12 genu valgum, and 20 controls) were enrolled in this study. Subjects with > 4 cm between th...

Silvereyes, Zosterops lateralis Latham, commonly feed on kiwifruit rejected for export and either stored in open bins at packhouses or in piles ready to be fed to livestock, and may play a role in the spread of wild kiwifruit in native and exotic forest in the Bay of Plenty, New Zealand. We determined the germination rate and percentage germination of Actinidia chinensis Planch. seed sown (1) a...

Synchronization of motor unit activity was investigated during treadmill walking (speed: 3-4 km/h) in 25 healthy human subjects. Recordings were made by pairs of wire electrodes inserted into the tibialis anterior (TA) muscle and by pairs of surface electrodes placed over this muscle and a number of other lower limb muscles (soleus, gastrocnemius lateralis, gastrocnemius medialis, biceps femori...

BACKGROUND McConnell recommended that patellar tape be kept on all day, until patients learn how to activate their vastus medialis obliquus (VMO) during an exercise program. This application may pose problems because prolonged taping may be inadvisable for some patients or even contraindicated owing to skin discomfort, irritation, or allergic reaction. HYPOTHESIS Wearing patellofemoral tape f...

The purpose of this study was to determine changes in intramyocellular lipid (IMCL) content in the vastus lateralis of nondiabetic, physically fit males over 72 h of fasting. Six men, mean age 35 yr (range 23-55 yr), body mass index 23.7 kg/m2 (21.2-27.4 kg/m2), undertook a water-only fast for 84 h. Vastus lateralis IMCL content was determined using proton magnetic resonance spectroscopy after ...

INTRODUCTION It has been investigated the mechanomyographic (MMG) signal may respond linear [1] or non-linear [3] relationship with force development Different relationship depends on contraction types, force levels, angular velocities and the muscles studied [1, 3]. Studies suggested that the MMG properties may also differentiate muscle fiber types [5]. The purpose of this study was to investi...
