Abstract
Purpose
To study the acute effects of proprioceptive neuromuscular facilitation D2 extended, dynamic, and static stretching on throwing velocity in collegiate softball players.
Methods
Fifteen male softball players from Chulalongkorn University softball club, aged between 18-24 years, were recruited in this study. They received 3 randomized types of stretching: static stretching, dynamic stretching, and proprioceptive neuromuscular facilitation stretching. The interval between each type of stretching was one week. The general physical characteristics and joint angular velocity at Shoulder, Elbow, and wrist were measured before and after stretching. Dependent variables were analyzed using One–way ANOVA and paired t-test. A significance level was considered at p<0.05
Results
The throwing velocity of collegiate softball players were no significant differences (p > .05) among proprioceptive neuromuscular facilitation D2 extended, dynamic, and static stretching. The static stretching showed significantly decreased (p<0.05) shoulder angular velocity compared to before the stretch.
Conclusion
Acute effect of dynamic stretching and proprioceptive neuromuscular facilitation stretching do not decrease angular velocity. This indicates that three types of stretching can be used for male collegiate softball players without a decrease efficiency of throwing velocity.
