Abstract
The purpose of this study was to make observational evaluation of throwing motion for adult women.
Throwing motions of 164 adult women were videotaped from side view. Dynamic variables for throwing motions were obtained from video analysis. The multiple regression equation to estimate throwing distance by dynamic variables was calculated by stepwise method. Selected variables by stepwise method were evaluation items.
Throwing motions of 35 adult women playing back by video were evaluated by 8 observers. Observers evaluated length of stance, position of non-throwing hand, maturation of whip-like action and type of leg motion during preparatory phase, separately. From evaluation of these four factors, score of whole throwing motion was calculated individually. As a result of probing varidity, reliability and objectivity of evaluation, evaluation designed in this study seemed to be effective.
