2.1.1. Measurement
The effect of plyometric training on the EMG of the biceps femoris and gracilis was measured when performing
the pre-test and, after 4 weeks of training, during the post-test. For better results, EMG changes for each muscle
were performed in the 2 virtual forms of absolute strength (Squat movement) and explosive power (vertical jump).
To prevent the negative effect of pressure resulting from the squat movement on the vertical jump, the latter was
performed first. To record the information, an MT machine was used, and MYO-Dat5 was used to analyze the data.
To perform the pre- and post-tests a multi-press rack, a wall-mounted sergeant jump scale, Megawin Ver.2, and an
MIE electro-goniometer was used.
