The Effectiveness Of Imaginary Training To Jumping Class Motor Skills And Its Mechanism

Motor imagery traing is a method that repeated the sports action or situations in the minds under the guidance of imagination, to improve motor skills and emotional control ability. In this study, we resrached the motor imagery training'effectiveness to motor skill learning from the form of technical ability and stage of development, and various techniques to study the movements and motor skills. From the brain electrical activity and psychological mechanism to explore the mechanism of motor skill learning. Combination the behavioral experiments and ERP techniques to investigate the motor imagery' cognitive processes. The full text is composed of three empirical research:Study I:Effects of exercise training in the mechanism of Motor image. The use of event-related potential ERP technology from the level of brain activity mechanism of functional equivalence. Experimental test of a classic mental rotation paradigm, through the body part (palm) and objects (letters) on the mental rotation experiment of mental rotation and the rotation of the functional equivalence of real objects. The second experiment preparation and representation from the movement preparation, movement imagery and movement execution process of comparative study of movement imagery and motion perception Brain Mechanism of functional equivalence.Study?:The effectiveness of Motor image Training used in jump class motor skills learning. Homogeneity test will be divided into physical practice group?Motor image group, Motor image+Physcial practice group, and control group. Imposed on subjects 90min/time,2 times/ week for 8 weeks of training experimental intervention. From the exercise capacity (related to physical fitness before and after comparison), a high degree of athletic performance (far degrees) changes in technical score and the action moves three technical analysis, the study of imagery training on motor skills learning.Study?:The brain mechanisms of motor image Training. Distinguish between four selected experimental paradigm used, the use of words induced representation, the process of movement imagery of the brain mechanisms. Five experiments using Oddball paradigm of image representation induced brain mechanisms.Results:(1) The reaction of material in the form a significant main effect (F (1,20)=13.14, p<0.01). Each group P300 amplitude, material forms a significant main effect (F (1.20)=49.68, p<0.001) materials, form and image form of a significant interaction (F (2.40)=3.54, p<0.05), simple effect of hand rotation case, pictures, forms a significant main effect (F (1,20)=5.16, p<0.05). The main effect of movement type was significantly (F (1,13)=25,13, P=0.00), P300 amplitude significant main effect for type (F (1,13)=4.01, P=0.041).(2) Group as the physical appearance of+kinesthetic representation capacity significantly increased (P<0.01), vertical jump height of a significant main effect (F (3,68)=3.96, P<0.05), jumping far from the main effect of the degree was not significant (F (3,68)=1.14, P> 0.05). Significant effect of the horizontal velocity (F (3,68)=8.87, P=0.004), instantaneous horizontal speed pedal (F (3,68)=2.54, P=0.36), vertical velocity from the ground off a significant effect (F (3,68)=3.35, P <0.05), A3 left hip angle effect was significantly (F (3,68)=3.58, P <0.05), the maximum swing speed of the swing leg a significant effect (F (3,68)=3.53, P<0.05), swing leg angle between the two legs off the ground an instant significant effect (F (3,68)=6.94, P<0.05), take-off leg in an instant effect on the body angle was significantly (F (3,68)=4.26, P <0.05). Swinging leg push off the ground an instant effect on the body angle was significantly (F (3,68)=13.77, P<0.05), H3 significant effect (F (3,68)=3.37, P<0.05).(3) P200 amplitude to practice the way a significant main effect (F (3.46)=1.49, P=0.048), amplitude of each group the trend of change IP> I> P> C. Way to practice the main effect of P200 latency was not significant (F (3.46)=1.04, P=0.056). Significant main effect of brain hemisphere (F (3.46)=64.34, P=0.000). LPP volatility of the way to practice a significant main effect (F (3.46)=3.24, P=0.016), the change between the groups for the IP> I> P> C. LPP latency way to practice a significant main effect (F (3.46)=3.24, P=0.016), latency in the order of each group C>P>I>IP. Practice methods of P300 amplitude of the main effect was not significant (F (3.46)=0.161, P=0.922), image type main effect was not significant (F (3.46)=1.987, P=0.155), practice methods of P300 latency main effect was significant (F (3.46)=3.014, P=0.047), the main effect of picture type of incubation was significantly (F (3.46)= 7.99, P=0.013).Conclusions:(1) Mental rotation is the rotation of real objects analogues, the main body movement representation also includes the cognitive processes of information processing. Sports and appearance, preparation and implementation of the task does not exist between any two differences in brain electrical activity. Motor preparation and representation for showing similar characteristics of brain electrical activity, exercise execution and movement imagery EEG showed similar characteristics.(2) The appearance of jump training in favor of action to improve performance, Motor image+physical group best. Improvement in athletic performance is better than physical training on the imagery training, but in the mastery of motor skills training on the motor image better than physical training. (3) Different training methods were tested on the ability to jump Imagery, Image Analysis Technology and the movement the accuracy and reaction time were significantly different. For the construction and maintain the appearance of movement, motor image+physical practice is an integrated practice approach works best, most conducive to learning motor skills.(4) Representation and the representation of the effectiveness of interventions during the activation of these brain structures are related to the degree, the higher the activation level of intervention the better, higher level of intervention the better activation.(5) Behavioral changes and EEG confirmed High Jump Long Jump STRAIGHTENING imagery training with a mechanism consistent.
