Objectives: The primary purpose of the present study was to examine the effects of a cognitive specific (CS) imagery intervention on the soccer skill performance of young athletes aged 7e14 years and determine if performance varied with age. Design: Participants were 143 soccer athletes belonging to 16 different teams. Teams were randomly assigned to either a cognitive specific (CS) or motivati...

iranian art is one of the richest artistic heritages in the world comprising different fields such as architecture, paintings, weaving, pottery, calligraphy, metalworking, petrography, etc. this art had inseparable link with nature; especially with plants and animals in different eras; and it has been interwoven with poetry and literature so that its glory, beauty and expression have increased ...

Hyperspectral imagery is nowaday widely used in numerous image processing fields. This imagery technique simultaneously acquires up to several hundreds of images of a same scene at different spectral wavelengths and stack them all in a data cube. Each pixel is therefore no longer a triplet of values as it is the case in classical RGB imagery, but a n−dimensional vector corresponding to a reflec...

the aim of the present study was to examine the effect of different types of imagery on the skills performance of 7-10-year-old soccer players. 45 children (mean age 8.44±1.13 year) with similar imagery abilitywere selected and randomly assigned to three groups (each group 15 subjects). the training protocol was performed three sessions a week for 6 weeks. data analysis indicated a significant ...

Numerous studies provide evidence that motor skill acquisition is associated with dynamic changes in cortical and subcortical regions. Athletes are a professional population who are engaged in extensive motor training for long periods. However, the neural substrates of extreme level motor performance have not been clarified. We used kinesthetic imagery task to induce the mental representation o...

The neurobiological processes underlying mental imagery are a matter of debate and controversy among neuroscientists, cognitive psychologists, philosophers, and biologists. Recent neuroimaging studies demonstrated that the execution of mental imagery activates large frontoparietal and occipitotemporal networks in the human brain. These previous imaging studies, however, neglected the crucial in...
