Basketball "Three Threats" Movement Technology Principle Analysis And Research

This research utilization movement biology mechanics three dimensional image survey technology method, catches a ball after to the Chinese CBA Jilin team athlete "three threats" the holding movement to carry on the photography, obtains the correlation data And will carry on the analysis to the image material, will analyze the technical parameter and the modern basketball holding technology principle will request the technical parameter will carry on the comprehensive analysis, compares, seeks describes the basketball" three threats" the movement technical characteristic and the rule, and will discover the weak link and the technical superiority, thus achieved the technical diagnosis the goal, will promote the basketball movement training scientific style to develop as well as instructs the modern training practice to provide the theory basis. Draws the conclusion below through the analysis:1. Correlation analysis indicated, because the basketball athlete frequently as necessary maintains the low center of gravity body state of motion in the competition which one kind is suitable, guarantee sunder the competition resistance condition can accurately complete each kind of technique tactic movement by the relative equilibrium condition, therefore, athlete's holding posture center of gravity all quite low, generally stands erect the posture center of gravity to blower than about 25%.2. Sees the preparatory formation from the experiment two feet spacing in to be bigger than the shoulder to extend time 10-15cm, is generally utilized, also is effective. Therefore the preparatory formation bearing surface oversized or the small spacing all has not conformed to the holding breakthrough preparatory formation requirement. From the experiment we also may discover team member's double foot stands draws up for around, like this expanded around the body the direction bearing area, enable the body to have in the around side upward stable performance advances.3. Athletes when make "three threats" the movement, whether the overall center of gravity as well as is various joints angle size poses "three threats" the posture standard immediate cause.4. The basketball game in the half-court attack,two leans 45 about region is attacks the team member to carry on individual attack and the coordinate best ground location, it will capture is most intense. Therefore, attacks the team member chooses the position when this, should use "three threats" the type to stand the posture, in addition the reasonable use location, inevitably will create the bigger pressure to opposite party, will force opposite party in to be flurried appears the loophole, thus will gain the fighter plane.
