The purpose of this study was to explain the possibility of improvement in running and overhand throwing abilities in high-school students through regular physical education classes. The subjects were 117boys and 95girls in the second grade of a high school. The subjects performed 100m run and ball throws hefore and after physical education classes, 10 times during 4weeks. The physical education classes were consisted of some kind of teaching materials for running and overhand throwing skills. The running and throwing motions were recorded with a VTR camera from the side view. By the posterior ohservation of the videotape, motor pattern of running and throwing was evaluated individually. The results were compared before and after the classes, to explain significant differences by the t-tests.
The results were summarized as follows;
1) The means of running time decreased significantly, and throwing distance increased significantly both in boys and girls.
2) Improvement in running time and throwing distance after trials was remarkable in lower revel subjects, before learning. And the some differences were found in the tendency hy sex and the events.
3) There was a large difference of running time and throwing distance as well in its growth in terms of sex. But the result of evaluated running and throwing motions shows that girls were more improved than boys. These results explain that it is possible to improve running and throwing abilities in high school students, and it is suggested that running and throwing (fundamental movements) practice for acquirement of appropriate motor pattern is important through regular physical education classes.
