تصميم و تصنيع جهاز إلكتروني لرصد و قياس بعض المتغيرات الكينماتيكية للاعبي رمي الرمح

Abstract EN

This research aims to conduct a biomechanical study of the mechanical values by designing an electronic device to measure angles and acceleration for throwers (disc - shot put) in general and (javelin throwers) in particular (designed by the researcher) and the device is mainly supported for its use In various throwing competitions such as javelin throwing to estimate the player's condition during performance، the device is tested and compared with the SIMI analysis software that depends on the image processing process ، and the results obtained are shown through the ability of the designed device to accurately estimate angles and acceleration and ensure a faster reporting rate than SIMI software The study was conducted on (3) players who were deliberately chosen in the javelin throwing competition and registered with the Assiut University team for the academic year 2020/2021 AD، and their ages ranged from (18: 20) years.

With the nature of the study، which is one of the studies concerned with describing and understanding the innovative device، describing its components and method of work، as well as measuring some of the kinematic variables for javelin throwers، and one of the most important results can be Use both Simi (TAMU) to measure body angle and corresponding velocity.

- (TAMU) is a real-time measuring device that uses memory cards to store data for users to extract data.

- (TAMU) provides advanced data، not raw data، which means that no further analysis is required using (TAMU)، and as it was possible to make a number of recommendations summarized in the diversity in the use of training aids، tools and auxiliary measurement devices when teaching and training throwers in general Especially javelin throwing.

The necessity of circulating the innovative device to measure some of the kinematic variables of javelin throwers within the training programs of the javelin runners.

Keywords: design of electronic devices، SIMI program، kinematic variables، angles and acceleration، for javelin throwing.
