effect of two different preconditioning protocols on muscular power output
the ability to optimize muscular power output is considered as a basis for successful performance in the most sports. the aim of this study was to investigate changes in dynamic exercise performance following a sequence of preconditioning isometric muscle actions. twelve nonathlete, active female volunteers (age: 16±1 yr, height: 162±6.34 cm, weight: 60±9.21 kg) participated in the present stud...
متن کاملCaffeine, maximal power output and fatigue.
The purpose of this investigation was to determine the effects of caffeine ingestion on maximal power output and fatigue during short term, high intensity exercise. Nine adult males performed 15 s maximal exercise bouts 60 min after ingestion of caffeine (7 mg.kg-1) or placebo. Exercise bouts were carried out on a modified cycle ergometer which allowed power output to be computed for each one-h...
متن کاملFeeding Performance and Muscular Constraints in Fish
Analysis of the feeding kinematics of Astatotilapia (a small cichlid fish) suggests the presence of peripheral feedback modulation of the motor pattern, allowing the act of suction to be abbreviated. In this way, the effort spent in suction is minimized. The biological significance of the development of such a modulating feedback system is not immediately obvious from a ‘classical ecological’ p...

یادگیری یک فرایند چند بعدی است که حیطه های مختلف شناختی، رفتاری، و عاطفی را شامل می شود. از آن جا که حیطه ی عاطفی ریشه در هیجانات و احساسات و حتی بر اساس برخی مطالعات خودآگاهی فراگیران دارد، محقق این مطالعه را بر اساس مدل هوش هیجانی دانیل گلمن انجام داده است. در این تحقیق توانش خودآگاهی به عنوان یکی از متغیرها دارای سه مولفه: خودآگاهی هیجانی، خود ارزشیابی صحیح، و اعتماد به نفس می باشد که ارتب...
Automatically Exploring Tradeoffs Between Software Output Fidelity and Energy Costs
Data centers account for a significant fraction of global energy consumption and represent a growing business cost. Most current approaches to reducing energy use in data centers treat it as a hardware, compiler, or scheduling problem. This article focuses instead on the software level, showing how to reduce the energy used by programs when they execute. By combining insights from search-based ...
