ABSTRACT

I show how the differences between novice and experienced

arms dribbling basketball operations. VICON motion capture

system and force plate systems are used.

Markers attached to the joints of the human body motion capture

suit to wear first. And get moving on the force plate. 12 cameras

to shoot their movements, used to preserve the position

coordinates of markers in 3D space. Motion analysis based on the

data.I show how to use different arm action for beginners and

inexperienced basketball dribble.

INTRODUCTION

The basketball pass, dribble, shoot there are three

movements. Important to focus on dribbling and movement

that can change the course of the game in this.Can escape

dribble and pass and shoot. The firm also acquire experience

that is said to be so difficult. Compare the movements of

novice and experienced Therefore, to clarify the differences,

and to improve the technology for beginners.

EXPERIMENT

Subjects

Dribble moves to focus on important basketball moves. Because in order to change the course of dribbling

game is crucial. And because people are not experienced but difficult to pass and shoot with learning

differences.

Measurement system

This experiment was measured by the optical motion capture system produced by VICON in University-

Business Innovation Center in Aizu campus.

Motion capture system

The 12 infrared cameras were operated at a sampling frequency 120Hz,its frame rate is 0.0083 sec. A set of

motion capture suits used 39 markers in these experiments. 31 markers were located at each joint, and 8

markers were at their sports shoes.

Force plate system

The force plate system measured the floor reaction force of X-Y-Z directions with 14 plates located on the floor

of the capture room. When subjects pushed these plates, this system measured the reaction forces.

MEASURENEMT OBJECT

Getting them to cooperate with right-handed subjects,

focused on the right arm when dribbling the basketball.

Shoulder, elbow, wrist, back of the hand with a marker,

we compared the location of each of the three-dimensional

coordinates of the marker.

Then, the shoulder, elbow and wrist to see how

differences obtained using the angle of the inner product

formula.

ANALYSIS

I had to help each one by one inexperienced and experienced

basketball.

The experience was participating in a regular 11-year history of

basketball games. Is 174cm tall.

No experience is no history of basketball, which have done little

novice physical education. The height is 166cm.

RESULTS

Inexperienced person• Overall, small angle of the shoulder.• Shows only the angle of the shoulder at the highest point of the ball.• Y coordinate of the shoulder, elbow wrist (right) are all different

locations.• There are significant changes in wrist angle.

The experience• Greater overall angle of the shoulder.• To change the angle of the shoulder smoothly.• Wrist elbow is equal to the Y position coordinate direction of travel.• Little change is seen in wrist angle, change can be seen only when

you release the ball from the hand.

CONCLUSIONS

Inexperienced person• Not use too much shoulder and elbow, wrist with a dribble.• Has been dribbling out the direction perpendicular to the

forward progress of the shoulder, elbow wrist at all times.

The experience• Use the shoulder and elbow, wrist without dribbling to

much.• When the ball is attached to the hand, tend to be parallel to

the direction of travel to the elbows and wrists.
