The effect of muscle stretching exercises on the peripheral speed of the throwing arm and achievement in discus throw for people with disabilities, category F34.

Abstract

Flexibility exercises (muscle stretching) are physical exercises that aim to
improve and develop some motor skills. Given the importance of muscle
strength in the skill performance of discus throwing for people with disabilities,
the longer the muscle, the greater the force it gives, which is directly
proportional to the distance achieved by the thrower. The ability of the muscle to
stretch, which reaches half the length of the muscle, gives greater strength and
speed to the arms when performing. This comes through some exercises for the
thrower's arm that contribute positively to this aspect. The aim of the study was
to identify the effect of muscle stretching exercises on the peripheral speed of
the throwing arm and achievement in discus throwing for people with
disabilities in the F34 category sitting. The hypothesis of the research was that
there were statistically significant differences between the pre- and post-tests in
the peripheral speed of the throwing arm and achievement in discus throwing for
people with disabilities in the F34 category sitting, in favor of the post-test. The
researcher used the experimental method using the single-group method, and
muscle stretching exercises were used for the throwing arm to increase its ability
to develop peripheral speed as well as achievement. The exercises continued for
(6) weeks with (3) training units per week. After conducting the post-tests, the
researcher concluded:
