Background technology
Feedback is a notion in the Control Engineering.In control system, a certain particular system is imported certain control signal, just can obtain certain output, import different control signals and can obtain different output effects.
Feedback is divided into two kinds of positive feedback and negative feedbacks, thereby the effect of feedback makes output bias reduce more appellation negative feedback near stationary value.
Along with feedback phenomenon continuous discovery and people's intensification that feedback phenomenon is understood in vivo, feedback technique is used in organism gradually, especially the people from one's body, a sub-subject---the bio-feedback that has so just produced feedback technique.
In the diving training, the sportsman also can be regarded as a control system.Its input signal is the limb action that the sportsman sends, opportunity that the size of having an effect during such as take-off, the direction of having an effect, connect in the air, open etc. moved or the like, and its output is exactly the quality that action is finished, as height of arch, take-off angle, rhythm of action, the entry angle, and the effect of tip entry etc.Such control system, the specific of its maximum is exactly the incomprehensiveness of input.Which type of input the sportsman at first needs to seek just can reach best output effect, secondly to constantly strengthen own so that oneself possess the ability of sending this input, input can be stabilized on this optimum value, and these are the purpose that the diver trains for many years just.
In order to help the stable input of sportsman, operating stably just, the coach need say action to the sportsman, and athletic limb action input, body system, action effect export, add that coach's language feeds back four parts and just formed a complete training negative feed back control system.Yet, be degeneration factor equally, also have the problem of an operating efficiency.Which type of negative feedback can make system reach stable the most fast.Though known existing diving training method can train high-caliber sportsman, yet the problem that more allows the people pay close attention to is the further optimization of system.Having does not have possibility that the time of training is shortened more, and the cost of training reduces more, and the rate of becoming a useful person of training improves more.In order to address these problems, be various with quadrat method, wherein in theory with every application in the method that all extensively confirmed, that improves feedback effects exactly, strengthens " feedback factor ".In conjunction with the training reality of diving event, just allow the sportsman know clearly oneself effect of finishing of action more, with the gap of standard operation where.So just can make the more autotelic adjustment input of sportsman, to obtain best output.
In the existing diving training control system, feedback operation is to be finished by the process of saying action by the coach.This process at first needs the coach to observe athletic action, and difference and the athletic action effect with athletic limb action and standard operation is processed into language and Word message within again, again by in a minute these information being conveyed to the sportsman.After the sportsman obtains these language messages, need in brain, be analyzed, be reduced into image information again.In this process, no matter be coach's observation, or coach's language performance, still athletic understanding, any one link goes wrong, and all can cause feeding back unsuccessful, and perhaps feedback information is wrong, and the operate as normal of system is interfered.See that such as the coach action is unsighted, perhaps coach oneself is incorrect to the understanding of action, and perhaps coach's ability to express and expression way are improper, and perhaps sportsman's comprehension is limited, or the sportsman can have influence on the effect of feedback to coach's distrust or the like.Therefore, if a kind of more directly reliable feedback system can be arranged, will effectively promote the performance that makes whole system.
