Izometric effort in the balance stance of handball throw

Postural balance plays an important role in high performance sports. The line between success and failure may be decided at such a small scale. In handball, postural balance may affect the accuracy of every technique that a played use, especially the throwing of the ball towards the goal. Our study aimed to identify the degree of influence that izometric effort has over the balance stance during a handball throw. Subjects: 210 1^st year students from the Faculty of Physical Education and Sport, Babeș-Bolyai University from Cluj-Napoca, were involved in this study. The subjects were both male and female, with the ages between 18 and 21 years old, with and without former performance athlete background. Materials: We’ve conducted the balance test using the AMTI NETforce BP 400600 force platform and the actual isometric exercises were completed in the same laboratory. Two types of planks and a half-squat were used as the isometric exercises. Results: There was no significant statistical difference between the balance variables before and after isometric exercises while holding the ball in hand. There was a significant statistical difference between the displacement before and after for the position without the ball. Conclusion: There is no impact of the isometric effort over the balance stance while holding the handball ball in the throwing position. We’ve identified a strong relation between the isometric effort and the balance stance without the ball in hand.
