the aim of this research was to examine the effects of pettlep-based imagery compared to more traditional imagery on learning badminton short service (backhand). for this purpose, 45 male students (age 12-14 years) were non-randomly selected and divided into three groups of 15 students each (they were beginners). the groups exercised in the following way: first group performed pettlep-based ima...

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 ...

BACKGROUND Fluoresence microscopy is an extremely useful tool to analyze the intensity, location and movement of fluorescently tagged molecules on, within or between cells. However, the technique suffers from slow image acquisition rates and limited depth of field. Confocal microscopy addresses the depth of field issue via "optical sectioning and reconstruction", but only by further reducing th...

motor imagery is the ability to imagine performing a movement without any action. the time a movement is mentally rehearsed highly correlates with the actual time of motor action. in this study, the effect of voluntary changes in imagery speed on the duration of the actual performance and learning a complex unfamiliar skill, and also the difference between the effects of real-time and fast imag...

a motor task performance and imagery show several parallel characteristics. in this study, the effect of a voluntary speed change in mental images of a complex difficult sequence of karate techniques on subsequent motor performance was assessed. 24 male karate volunteers (mean age: 24.58±5.27 years) who were well skilled at performing the sequence movements participated in the pretest. during t...

The aim of this study is to determine the impact of imagery on self-efficiency and spike implementation of girl volleyball players in Tafresh, considering the mediating role of positive self-talk. For this purpose, in a non-equivalent pretest-posttest control group design, 45 female football players aged 17-25 with sports record of 6 months to 2 years were selected out of high schools and uni...

The applications of information technology as a continuous process of monitoring the various ocean parameters such as salinity, temperature, the number of waves, the movement of fish, soil and turbidity. However, there is a sporadic attempt in assessing the wave heights which is one of the important parameters to project the roughness of the sea and the smoothness of the sea bed. Once a boat ma...
