The present study aimed to investigate the levels of maximal strength and muscular electrical activity, and to determine the quantitative indicators of the contribution ratios of electromyographic (EMG) activity of the working muscles during the actual performance of the shot put event in athletics.
The results revealed a strong correlation between performance achievement, maximal strength, and the EMG activity of the working muscles during the execution of the shot put, particularly in the trunk muscles, followed by the right thigh, left thigh, right arm, and finally the left arm. It was found that a higher level of electromyographic activation (EMG) is associated with achieving a greater throwing distance.
The main conclusions indicated that explosive power in the shot put event depends on the efficiency of neuromuscular activation of the major muscle groups. Moreover, EMG technology can serve as a predictive indicator of performance level among throwers.
The most important recommendations emphasize the necessity of identifying the value of EMG activity of the working muscles during performance and determining their relative contribution to the overall achievement. Training programs should be designed and regulated according to the obtained findings to ensure the correct direction of the training process.
