دراسة مقارنة للنشاط الكهربي للعضلات العاملة لمهارة الضربة الرافعة الأمامية كمؤشر لتوجيه الأحمال التدريبية للاعبي الريشة الطائرة للكراس المتحركة فئتي (wh1 wh2,)‎

Abstract EN

The study aims to compare the electromyographic activity of the agonist muscles of the clear strike skill as an indicator for directing training loads for wheelchair badminton players (WH1, WH2).

in this study, six players were divided into two categories of wheelchairs (WH1, WH2), with three players in each category, and measurements, analyses, and data on muscle activity were extracted using EMG.

the most important results were that they achieved the highest average percentage of muscle contribution to the performance of the clear strike for wheelchair badminton players was for the triceps brachii muscle, and then the wrest flexor muscle during the performance of the execution phase for WH2, and WH1 players.

the results showed that the Infraspinatus muscle, forearm, and upper arm muscles were the ones that depended mainly on WH1 players in performing the skill of the clear strike, while the Latissimus Dorsi muscle, forearm and upper arm muscles were the ones that mainly depended on WH2 players to perform the clear strike.

in addition, the rectus Abdominus was less activated by WH2, WH1 players.

thus, the researchers recommended the necessity of directing training loads during the development of training programs according to the percentages of the electromyographic activity contributions of the working muscles according to the degree of disability, whether WH1 or WH2 during the performance of the clear strike for wheelchair badminton players.
