The purpose of this study was to determine the immediate effect of three types of shoe insoles, on electromyography activity of selected lower extremity muscles during running on treadmill. The electromyography activity of the rectus femoris, vastus lateralis, vastus medialis, biceps femoris, tibialis anterior and gastrocnemius lateralis muscles of 14 male athletes were recorded in non-insole,...
background: alterations in the neuromuscular control of the spine were found in patients with chronic low back pain (clbp). sudden loading of the spine is assumed to be the cause of approximately 12% of lower back injuries. however, some aspects of this problem, such as alterations in the sensory–motor control of the spine, remain questionable. this study investigated postural and neuro–motor c...
Objectives: Each step during gait requires different attention demands that will affect muscles activity. The study of changes in the timing and intensity of the muscles activity in walking with dual task has received less attention from researchers. The purpose of this study was to evaluate changes in electromyography patterns of gait with cognitive dual tasks in balance impaired elderly. M...
Objective: The aim of present research is to compare the myoelectric activity of some chosen upper extremity muscles while doing bench press in two training methods of TRX and barbell bench press. Methods: Ten physically healthy students of physical education with experience in TRX participated in the study. Electromyography Bio Vision sixteen-channel and surface electrodes were used to calcul...
the aim of this study was to investigate the effect of 8 weeks of endurance and resistance training on the activity of g4 acetyl cholinesterase in fhl and soleus muscles of rats. 24 male wistar rats (age: 10 weeks and weight: 171.94±8.961 gr) were randomly divided into 3 groups (control, endurance training (et) and resistance training (rt)). et and rt groups carried out 8 weeks (5 sessions per ...
Background and purpose: Previous studies have investigated the correlation between activity of superficial trunk muscle and postural control in patients with low back pain (LBP), but the relationship between deep trunk muscle activity, as spinal stabilizer, and postural control during standing postural tasks is not clear yet. This study investigated the relationship between abdominal musc...
Objective: Low back pain (LBP) is one of the most common and costly health problems. Changes in muscle activity and recruitment of lumbar deep muscles which are responsible for lumbar spine stability have been reported in patients with LBP. Different exercise programs are used in the treatment of such patients to improve spinal stability. The purpose of this study was to systematically review t...
diazinon is one of the highly consumed organophosphorous pesticides. it inhibits cholinesterase enzyme in animal tissues. due to permanent residence in agricultural drainage channels, the swan mussel (anodonta cygnea) can be considered as one of the most suitable indicators of such pollutants. at the present study, acethyle cholinesterase activity of a. cygnea was measured when exposed to vario...
Purpose: Genu varum deformity changes the line of gravity from center of knee towards the medial side. This deviation results in changes in the upper part of the lower extremity that can affect postural control as well as the position and activity of the proximal muscles of the knee joint, like the gluteus medius muscle. Therefore this study aims to investigate the effect of genu varum disorder...
مقدمه: سکته مغزی عامل ایجاد عوارض طولانی مدت در بیماران است. از مهمترین عوارض ناشی از سکته مغزی، کاهش تعادل در وضعیت ایستاده و در هنگام راه رفتن و ضعف عضلانی می باشد . هدف از این تحقیق بررسی تاثیر تمرینات ترکیبی ایزومتریک و ایزوتونیک بر تعادل ایستا و قدرت عضلانی (muscle test) بیماران سکته مغزی است. روش شناسی: این پژوهش از نوع نیمه تجربی بود. شرکت کنندگان در این تحقیق را 30 بیمار مرد مبتلا به ...
