Abstract
Analysis of the electrical activity of some of the working muscles in the backspin stroke for table tennis players Abstract The study aimed to analyze the electrical activity of some of the working muscles in the backspin stroke for the table tennis players and recognizing the important muscles that are involved in performing the backspin stroke, both the relatively high and the strong speedy low. The study also shows the relationship between the capacity of the electrical response and the speed of the electrical response of some of the working muscles during performing the backspin stroke, both the relatively high and the strong speedy low. The study used the descriptive approach with a sample that consists of four table tennis Swedish players. One of the most important results was that the biceps muscle was much more involved in the muscular working during performing the backspin stroke, both the relatively high and the speedy low, whereas the rest of the muscles were involved differently according to their maximum contraction in the muscular work. The results showed that whenever the capacity of the electrical response increases its time decreases. Therefore, there is an inverse proportionality between the capacity of the electrical response and the time of the electrical response during performing the backspin stroke, both the relatively high and the speedy low.
