Kinematical Analysis On The Braking Technique Of Elite Male Dragon Boat Athletes

Rowing dragon boat sport is one of the important core technology, kinematics analysis was carried out on the dragon boat rowing athletes excellent technology, to reveal the rowing technique of the structure of the law, understand the overall framework of rowing technology, find the key links in the dragon boat sport paddle technology, thus scientific diagnosis technology of paddle, explore a reasonable and best technical solution, for the individual and the overall technology to provide scientific reference for teaching and training.Using three-dimensional photographic measuring method for the northeast dianli university man dragon boat athletes dragon boat shot point fixed-focus dynamometer, With stereo calibration, a three-dimensional framework, Using The United States The APAS System three dimensional analytic System analyzes The kinematics parameters on The paddle, The data point out:Look from rowing rhythm, Blade Angle of peak appeared in vertical moments,Rowing rhythm is reasonable: 20% of the pull blade front; 32% of the paddles in the back, 48% of the paddle back stage.From the characteristics of vane Angle, Peak OARS, hip at around 30 °advisable, shoulder joint Angle between 120 ° to 130 ° advisable, pull the OARS in the 165 ° elbow joint Angle between plus or minus 10 ° advisable, at the same time pressure paddle Angle between 125 ° to 145 ° elbow joint can effectively fixed blade.Out OARS, hip to control at 84 ° or so, after the body not too much. Out OARS to pull back to paddle blade elbow joint Angle control between 70 ° to 90 °.Look from the action link characteristics, oar upper limbs link activity sequence is: the left shoulder, left elbow.From the joint trajectory, pull after oar to level, at this point the least force component. when vertical to the point, pressure oar to feathering moves backwards with the pressure. Out OARS OARS, back stage, pressure oar to slightly tilt to inside,then back to the OARS.Suggestions to the teaching training: pay attention to the linkage between the inserted blade, blade. In pull should be paid attention to during the process of oar oar power sequence of shoulder joint, elbow joint, consolidate "to shoulder belt andshoulder strap arm" pull blade technology, maintain the stability of the body center of gravity. In the usual physical fitness, skills, strengthen the training of the waist and abdomen, shoulder joint muscle in training, To improve the flexibility and strength around the hip and knee muscles, thus improve the spin angular velocity and hand speed.
