Introduction: Ramadan is a time when Muslims are expected to be calm and peaceful in daily life both mentally and physiologically. Some people believe that they should try to don’t have be involved in bad and deviant behaviors in Ramadan. As increasing social safety and reducing crime in society are the most important concerns of the authorities , psychologists, sociologists and governments, th...
[ 2 ] - توسعه سیستم تحویل دارو مبتنی بر اگزوزوم در درمان سرطان: مطالعه مروری
در عصر حاضر شیوع سرطان در سراسر جهان درحال افزایش است، تاکنون روش‌های زیادی برای درمان و متوقف کردن آن انجام شده است اما مقاومت این بیماری در برابر داروهای ضد سرطان فعلی، نیاز جدیدی به ترکیبات دارویی جدید و سیستم تحویل دارویی را فراهم آورده است. نقص سیستم ایمنی بدن می‌تواند منجر به رشد تومور و پیشرفت آن شود. بنابراین ایمونوتراپی سرطان از جمله مواردی است که سبب جلوگیری از پیشرفت تومور میشود، اگ...
[ 3 ] - The Effect of Early Progressive Isotonic Exercise Therapy on Static Balance Control of Patients with Total Knee Replacement
Purpose: Knee osteoarthritis (OA) is believed to be an important risk factor for falling. Total knee replacement (TKR) is a commonly used choice when other methods are not satisfactory. Proprioception impairment, risk of falling and balance disorder are within the main complications of this method. While multiple protocols have been suggested for TKR, efficacy of early isotonic ...
[ 4 ] - Selected Kinematic Characteristics Analysis of Knee and Ankle Joints During Block Jump Among Elite Junior Volleyball Players
Purpose: The present study examined selected kinematic characteristics analysis of knee and ankle joints during block jump in elite junior volleyball players. Methods: Thirty male junior elite volleyball players (Mean±SD age: 18.14±1.12 y, height: 197.10±3.16 cm, sports history: 4.39±0.95 y, & weight: 771.20±59.83 N) participated in this study. A time-synchronized 5-camera sampling at 100 Hz w...
[ 5 ] - تاثیر آتل گیری اندام فوقانی بر سرعت و آهنگ راه رفتن
مقدمه و اهداف حرکات اندام فوقانی و دست ها میتوانند الگوهای حرکتی راه رفتن را تغییر داده و یا در آن مداخله ایجاد کنند، اما معمولا در تجزیهوتحلیلهای راه رفتن این بخش نادیده گرفته میشود. هدف از پژوهش حاضر بررسی تاثیر آتلگیری اندام فوقانی بر سرعت و آهنگ راه رفتن میباشد. مواد و روش ها از 30 نفر آزمودنی سالم (میانگین±انحرا...
[ 6 ] - Comparative Analysis of Jumping and Landing Velocity of the Young Elite Spikers of the Iranian National Volleyball Team While Performing Block Jump
Objective: Accurate velocity analysis is essential when performing the block jumping technique on the net by various spikers because it will improve this performance and prevent injury. This study aimed to compare the jump and landing velocity of the Iranian national team’s young elite spikers when performing block jump skills. Methods: A total of 21 young elite male volleyball players of the...
[ 7 ] - Block Jump Height Assessment Based on Kinetic Approach in Volleyball Players: Is There any Difference Between Methods?
Purpose: Various kinematics and kinetics methods have been proposed for the assessment of jumping ability as a critical skill in professional volleyball players, but little is known about the accuracy and differences between these methods. Therefore, the objective of the current study was to answer the question “Is there any difference between the results of various kinetic methods in the asses...
[ 8 ] - The Effect of Combined and Core Stability Training Program with Protective Measures on Selected Variables of Physical Fitness of Junior and Young Volleyball Players during the Coronavirus Pandemic
Objective: The aim of this study was to investigate the effect of a combined and core stability training program with protective measures on selected variables of physical fitness of junior and young volleyball players during the coronavirus pandemic. Methods: 15 male volleyball players [18±1.06 yrs.] after the end of the first quarantine period and then after a 12 weeks period of combined an...
[ 9 ] - The Effects of Increasing Running Speed on Three-Dimensional Peak Angle of the Lower Limb Joints in Stance Phase
Objective: Attention can be paid to the biomechanical characteristics of running since the speed of running varies. The aim of the present study was to investigate the effects of increasing running speed on the three-dimensional kinematics of the lower limb’ joints in the stance phase. Methods: The research was quasi-experimental. 27 volunteer subjects ran on a treadmill and the kinematic and ...
