The purpose of this study was to investigate the spiking motion on the skill level using an observational evaluation method and the bio-mechanical analysis. Subjects of this investigation were 27 male and 82 female junior high school students who had attended volleyball class for 7 times. Nineteen key categories were selected for evaluating the spiking motion. Subjects were taped by VTR (shutter speed: 1/500 sec.) on the process of taking a spike skill test.
The main results obtained were as follows:
1) Spiking motion of junior high school students was classified into 8 typical patterns.
2) Spiking motion on each subject was upgraded and gained its accuracy because of motor learning in their volleyball class.
3) Spiking pattern that was classified by observational evaluation method had related to the spiking skill accuracy.
4) Typical spiking patterns that were classified by observational evaluation method were analyzed bio-mechanically using stick picture and the locus of center of gravity. There were remarkable differences between unexperienced spiking patterns and experienced one. That is, the spiking motion form drawn by stick picture was more smooth and the alteration of center of gravity to vertical direction and horizontal direction was more remarkable on superior spiking patterns.
