Embodiment Construction

[0065] Such as figure 1 As shown, the pole vault exercise training method of the present embodiment may further comprise the steps:

[0066] Step 1: Obtain the movement trajectory of key parts of the human body during pole vaulting;

[0067] The motion trajectory adopts the OptiTrack three-dimensional infrared motion capture system. By arranging markers on the human body, the high-speed camera receives the infrared light reflected by the markers and obtains them by identifying the markers. The high-speed cameras used in this embodiment are 12 Prime13s (p13 for short), and the highest frame rate is 240fps.

[0068] Step 2: extract feature vectors from multiple motion trajectories collected in step 1;

[0069] Step 3: Merge the feature vector obtained in step 2 and the quantity representing the success of the bar into a new feature vector as a training sample, and obtain N training samples. And set the activation function as g(x), the maximum number of iterations G max And t...

Abstract

The invention discloses a pole vault sports training method. The method comprises the following steps of 1, obtaining key part movement tracks of the human body in a pole vault process; 2, extractingfeature vectors of multiple movement tracks; 3, merging the feature vectors and variables for representing whether a pole vault is successful or not into new feature vectors; 4, adopting an empiricalvalue estimation method to initialize parameters NP, F and CR, and randomly generating an initial population; 5, calculating an implicit strata output matrix to obtain output weights and root-mean-square errors corresponding to the output weights, wherein the root-mean-square errors serve as a fitness index; 6, conducting variation and crossover operation to obtain a new individual; 7, judging whether to continue to conduct model training or not according to iterations; 8, adopting a testing sample to test the model, and finally establishing a pole vault sports training model and using the model to conduct training. By means of the pole vault sports training method, the problems in training can be quickly and effectively found out, and thus nonstandard skilled movements of sportsmen are corrected.

Description

technical field [0001] The invention relates to the technical field of sports training, in particular to a pole vault training method. Background technique [0002] The pole vault is one of the most technically complex events in track and field. In pole vaulting, take-off, tucking, and crossing the pole are some of the more important basic techniques. In order to cross the bar, the athlete must gain a certain amount of kinetic energy through the run-up and take-off, and complete the air movement in the tangle stage to pass the bar. The quality of the take-off tandem action directly affects whether the athlete can successfully pass the pole. In the process of take-off, tuck, and pole passing, the athlete's speed, take-off angle, trajectory, position and distance from the bar are very important. [0003] my country's pole vault performance is currently improving rapidly, but its overall level has been lagging behind the world, and its ranking in Asia is not satisfactory. I...
