=-0.42 p = 0.025) and a positive correlation was obtained among the average scores in with and without sound situations (cor. Results: A negative correlation among average and CV in the without sound situation was obtained (cor. The EMD variables calculated in both situations, with and without sound stimulus, were the average and the coefficient of variation (CV).

A Surface Electromyography and a contact sensor were used to assess the electromechanical delay (EMD). Material and Methods: Twenty-eight recreational Boccia players eligible to play Boccia (BC1 and BC2 classes) took part in this study. In our study it has been used the electromechanical delay (EMD) of finger extensors during ball realizing in two different situations: with/without command constrains to discriminate between BC1 and BC2 Boccia classes. Introduction: In Paralympic Sports is crucial to use tools to discriminate between sport classes.

The research conclusions are the series of underhand throwing boccia if want to produce the throwing accuracy near the target, then start was done with an angle of 98.1° and force of 0.24 N. Player C experiment 1 result better targeting accuracy when compared to experiment 2 and experiment 3, because experiment 1 had arm angle of 98.1°, the throw angle of 20°, speed of 0.033 m/s and force of 0.24 N.

In player B experiment 2 produces a better target accuracy compared experiment 1 and experiment 3, because experiment 2 has an arm angle of 56.5°, throw angle of 27°, speed of 0.036 m/s and force of 0.48 N. The results showed in player A experiment 3 produces better target accuracy compared experiment 1 and experiment 2, this is because experiment 3 has an arm angle of 69.6°, throw angle of 25°, speed of 0.040 m/s and force of 0.44 N. Data analysis was performed with dartfish software. The study was used descriptive analytical research method with samples of 3 Boccia athletes. The study purposes were analyzed the angle and style of Boccia athlete which results in accurate targeting of throwing underhand movement. The greater force moment, the greater force generated by producing throw away or accurate results approaching target. When throwing ball, the force moment comes into play. Throwing ball means moving object in the form of ball to move to certain distance. Throwing becomes a basic movement skill in the form of movements with limbs in a more skilled manner.
