background: primary dysmenorrhea is the most common cyclic pelvic pain and is also the most common gynecological problem worldwide and affects quality of life. the present study aimed to investigate the effect of isometric exercises on intensity and duration of pain and level of anxiety in the students with primary dysmenorrhea. materials and methods : in this randomized controlled clinical tri...

Aims: Active and progressive resistance training has a key role in functional recovery and quality of life in patients with MS. Therefore, this study aimed to investigate the effects of isotonic and isometric exercises on balance and ability in patients with MS. Materials & Methods: In this randomized clinical trial, 60 patients with MS admitted to MS Special Diseases Center in Yasuj during 20...

A second order rotatable design was used to obtain polynomial equations describing the effects of combinations of sulfur dioxide (SO(2)) and ozone (O(3)) on foliar injury and plant growth. The response surfaces derived from these equations were displayed as contour or isometric (3-dimensional) plots. The contour plots aided in the interpretation of the pollutant interactions and were judged eas...

Movements generated by muscle contraction generally include periods of muscle shortening and lengthening as well as force development in the absence of external length changes (isometric). However, in the specific case of resistance exercise training, exercises are often intentionally designed to emphasize one of these modes. The purpose of the present study was to objectively evaluate the rela...

this study presents data on age structure, sex ratio, growth, length-weight relationships and condition factor of four populations (n=312) of  two alburnoides species, collected in 2005 and 2006 from the tajan river (caspian sea basin), the ghara-chai and jajrud rivers (namak lake basin), and cheshmeh-ali spring (kavir basin) of iran. sex ratio of the fish, in the studied localities, except in ...

early body shape changes of beluga sturgeon were studied using landmark-based geometric morphometric approach to recognize its allometric growth pattern. sampling was done from hatching up to 50 days post hatching (dph). left side of specimens were photographed using digital camera and nine landmark points were digitized on two-dimensional images. total length (ti) was measured using the softwa...

In vitro isotonic and isometric mechanical properties of the sternohyoid (SH) muscle, an upper airway dilator muscle, were studied in rats with a growth hormone (GH)-secreting tumour (GH tumour group; n = 10). The effects of muscle fatigue were also studied. Stress and shortening were measured in muscles contracting from zero load up to isometric load under tetanic conditions. Isometric stress ...

Highlight Research on pirik endemic fish (Lagusia micracanthus) was first conducted in the Gilireng River. Based length-weight relationship, growth type of River is isometric. The average size distribution, total length, and body weight female were greater than those male though not statistically significant. water conditions are sufficient to support fish. Abstract Lagusia micracanthus or loca...
