DIFFERENCES IN BIOMECHANICAL PROPERTIES OF KNEE EXTENSOR REBOUND WITH THE DIFFERENT SURFACE ELASTICITY
Journal Title: Sport Mont - Year 2013, Vol 0, Issue 37
Abstract
The sample includes 40 subjects of both sexes: male (20) and female (20) population of students of the Faculty of Sport and Physical Education, University of Nis. The research involves the application of the rebound in gymnastics with two different heights (40 and 50cm) on three different surfaces of elasticity: hard, demyelastic and elastic surface. The subject of the research were the dynamic parameters of movement laid down from Drop Jump (DJ) with Myotest device and in the following parameters: height (in cm), power (in W/ kg), force (in N/ kg) and speed (cm/ s). Using canonical-discrimination analysis showed no statistically significant differences in the performance jump of hard and demyelastic surface from a height 40 cm and 50 cm for men and women, thethe studied parameters (height, strength ,power and speed of the bounce ). Revealed a statistically significant difference in performance with the elastic rebound surface elevations of 40 cm and 50 cm for men and women (p = 0.00). Of the examined parameters was obtained that there are significant differences in the Force reflection to the significance level of 98% (0.0255) and the power of reflection on the significance level of 100% (0.0009) in men. In women of the examined parameters was obtained a statistically significant difference in the strength of the rebound only from positions of 40cm and 50cm and 100% (0.0075).
