چکیده پژوهش حاضر به منظور تعیین تأثیر شدّت گرم کردن بر شاخص‌های قلبی تنفُّسی بازیکنان مرد نخبة فوتبال انجام شد. آزمودنی‌های پژوهش را 10 مرد جوان نخبة فوتبال از باشگاه‌های تهران در ردة سنّی جوانان و امید با میانگین سنّی 1±20 سال، میانگین شاخص تودة بدن (BMI) 05/2±65/21کیلو گرم بر متر مربع، و میانگین قد 04/0±78/1 متر تشکیل می‌دادند. آزمودنی‌ها، در دو جلسه و به فاصلة 72 ساعت، دو برنامة گرم کردن، با شدّت...
The aim of this study was to Compare the effect of resistance training with active and passive rest on aerobic and anaerobic fitness in soccer players. For this purpose 16 players of Foolad Mobarakeh Sepahan club, accidentally were divided into rest and active group (Height 177.78±6.68 cm, Weight 64.88±7.97 kg, age 18.22±0.83 years ,and percent fat 20.47±1.8) and rest passive group(Height 17...
The results showed that the microhardness and tensile strength of the heat-affected zone as the weakest welding zone in some samples reduced up to 30% compared to the base metal. On the other hand, a decrease in rotational speed, an increase in tool movement speed, and the number of welding passes cause grain refinement and improve mechanical properties. However, the effect of decreasing the ro...
Objectives: The purpose of this study was to evaluate the concurrent validity of the Farsi version of Functional Gait Assessment (FGA), Timed Up & Go (TUG), and Gait Speed tests in Persian communitydwelling older adults. Methods: Subjects were 100 males in falling or no falling history group (50 subjects in each group). Subjects were community-dwelling adults aged 60-90 years who were living...

We consider shortest paths on a multi-modal transportation network where restrictions or preferences on the use of certain modes of transportation may arise. The regular language constraint shortest path problem deals with this kind of problem. It models constraints by using regular languages. The problem can be solved efficiently by using a generalization of Dijkstra’s algorithm (DRegLC). Rece...
Fast optical circuit switches with large port count will allow flexible bandwidth allocation in datacenter networks by augmenting electrical packet switching. Reported herein is the development of a microsecond-speed optical circuit switch with 50×50 port counts implemented on silicon photonics platform using MEMS-actuated directional couplers. The switch contains a number of innovative enhance...
