Description
Technical field
The present invention relates to the athletic training field tests, particularly a kind of trampoline synchronizing testing system.
Background technology
Trampoline is collection artistry, a sight, athletics and recreationally is the high-grade of one, high-level artistry project, it stop with gymnastics, skill, art grasp, diving belongs to the skill project.Trampoline is attracting countless spectators with its distinctive action aesthetic feeling and artistic charm, enjoys the good reputation of " aerial ballet ".Trampoline is existing nearly 70 years developing history in the west, yet still is an emerging project in China.After 20th century the mid-90, particularly Sydney Olympic Games, China's trampolining fast development, competitiveness improves fast.Calendar year 2001 is in the 15th world teenager trampoline championship that Denmark holds, China sportsman has won 3 pieces of gold medals, 4 pieces of silver medals and 1 piece of bronze medal at one stroke, shock international trampoline circle, fully shown China trampoline back exercise person's sports strength and development potentiality.The trampoline project has become the new gold medal growth point of Chinese sports, is the potential advantages of the project that the 2008 Beijing Olympic Games is expected to impact gold medal.Though having in China, trampoline trains basis and development prospect preferably, but because this motion is not long in the time that China carries out, the understanding of trampoline features on project, training rule and method still is in gropes the practice stage, theoretical research feedback relatively is weary, particularly lacks the detection means of science.
In the project of trampoline training and competition, the synchronous and Women's Diving Synchronized 3m Springboard synchronizing project of Men's Diving Synchronized 10m Platform is arranged, finish the action of identical difficulty on the trampoline of two each comfortable laid parallels of sportsman of its regulation simultaneously.In trampoline match synchronously, " judge synchronously " can be according to the synchronism of two athletic set pattern performance, evaluate " the synchronous branch " of this set pattern, " dividing synchronously " adds that " technical point " adds " the difficulty branch " of this set pattern is that sportsman one overlaps final score of synchronous set pattern.Synchronism is meant take-off when two sportsmen do same action, whether touch net consistent, and the quality of its time extent decision synchronism is if the bright synchronism of mistiming novel is good, its synchronous score is just high, otherwise if the mistiming greatly then illustrates poor synchronization, its synchronous score is just low." judge synchronously " and coach are to judge athletic synchronism by eyes at present, provide " dividing synchronously ".How objective, to scientifically measure athletic synchronism be one of present urgent problem.
Look into newly by retrieval, it is that " detecting the process and the application of people's action number on the trampoline " of DE102005051960B3, " sensor and time system and correlating method ", the patent No. that the patent No. is US6825777B2 are that " counting assembly of bounce bed ", the patent No. of CN2537419Y is 00225653.3 " trampoline " etc. that the patent No. is arranged in the prior art.Wherein patent DE102005051960B3 discloses a kind of trampoline, and 4 sensors are installed on it, is connected with computing machine.By the deformation values motion of writing down personnel on the trampoline of test trampoline, but the synchronism of this patent can not be to the double synchronous training and competition of trampolinist the time measured.
