Popis: | 100 Purpose of this study: the use of wireless micro electro mechanical system (MEMS) sensors, analysis of the vertical position while playing elite and sub- elite athletes, while playing five sports segments and with the ball being kicked hit when the acceleration and angular velocity differences. Methods: The use of micro-electromechanical triaxial acceleration regulations and gyroscope combination of wireless MEMS sensors and capture the elite and sub- elite athletes of all four (dominant leg are the right foot), playing in a vertical orientation, the main five sports segments and with the ball kicking the acceleration and angular velocity data for statistical analysis. Results: 1. Between elite and sub-elite athletes with or without wear sensors, no significant difference. 2.Ball spectrum analysis, analysis in the average of the acceleration data on the XYZ axis, the difference between the elite and sub-elite athletes, no significant difference in the impact of larger XZ-axis elite group of athletes, there are significant differences between elite and sub-elite athletes. The angular velocity of the average of data analysis, the difference between the elite athlete group in the XYZ axis, and a greater impact in the XZ axis of elite and sub- elite athletes action was no significant difference 3. Body limb acceleration and angular velocity of the minimum by the ANOVA analysis showed no significant difference. 4. Body limb acceleration and angular velocity average by ANOVA analysis of all significant differences in the XYZ axis. 5. Body limb acceleration and angular velocity of the total power of XYZ axis there is significant difference. 6. Body limb the elite and sub-elite athletes total power of the acceleration and angular velocity triaxial significant differences between the players. 7. Athletes movement stability in the larger impact of the right ankle gap more obvious, the other limb difference is not large. In the movement stability of the ball and the limb segment, the stability of the elite group of athletes mostly superior to the sub-elite group of athletes, again the ball and right ankle movement stability of the gap is more obvious. 8. Body limb kinetic chain curve, three-axis force for elite athletes than the average, and the force point in time would be more close to playing the role of time, sub-elite athletes sometimes have premature or excessive force and strength in favor of one axial situation. 9. Body limb segment than sub-elite athletes in the triaxial average and synthetic force in his right ankle acceleration average, good players are. 10. Elite athletes maximum and total power in the left ankle on the average and synthetic force to value. 11. Triaxial angular velocity of the average on the right ankle, the elite athletes in the maximum and minimum values have a larger average value of the elite athletes in the maximum synthetic force is also better than sub-elite athletes, the total power greater the average and the synthetic force value. Concluded that: 1. Rugby vertical positioning play instant collision value, which ball is the largest order of the right ankle, left ankle, right knee, left knee, coach training can strengthen the lower limb segment muscle, muscle endurance training to enhance instantly the kicking force in order to increase ball speed. 2. Gyroscope used in the size of Rugby to play test each segment of the angular velocity of the action found that ball angular velocity of the largest order of the right ankle, right knee, left ankle, left knee, these values can be used as the future play in the lower limb joints rotation direction and force size reference. |
