발레 동작의 운동학적 분석 - 파드샤(pas de chat)를 중심으로 -

Abstract

This research tried to find out temper of movement and suggests scientific basic information which is need for acquisition of right movement and right implement for ideal improvement of movement implementation throughout image analysis of Pas de chat movement which is to examine the necessary times, durations of flight, angles of knee, movement displacement of body center, velocity of wrist and so on. I analyzed these movements throughout synchronization system "Data Station". For gymnastics changeable range throughout human model, I analayzed necessary times for each situation, durations of flight for both feet's meeting point, angles of knee, movement displacement of body center, velocity of wrist. I also tried to examine gymnastics differences regarding movement kind when doing ballet Pas de chat between professional(skilled) and unprofessional (unskilled) ballerina. I picked 2 female professional ballerinas from "U ballet team"who have 16 ~ 17years career and 1 female student who has ballet major at S university and 5 years career. They all have not had bone or muscle disease ever. 1. As a result of dividing Necessary time into necessary times of each aspect and durations of flight, skilled ballerina's records were longer than unskilled one's for both. It is considered that they have enough time to minimize angle of knee in the air and also they make durations of flight long in order to make their legs movement easy. 2. When doing Pas de chat, skilled ballerina's knee angle was smaller than unskilled one's. We consider this means as knee angle is smaller, it is ideal for Pas de chat in case of both preposition and knee angle as right foot and left foot cross. 3-① For body center's changeable rage of left, right movement, skilled ballerina's record was smaller than unskilled one's record. This is moving jump action but in case of unskilled person, the reason is body center was moved far to side. 3-② For body center's changeable rage of back and forth movement, skilled ballerina's record was smaller than unskilled one's record. Because Pas de chat action is not back and forth movement but jumping high and moving to side little. 3-③ For body center's changeable range of vertical movement, skilled ballerina's record was higher than unskilled one's record. Becuase jumping high is the most inportant action for Pas de chat, the higher vertical changeable range the more ideal Pas de chat action. 4. Skilled ballerina's velocity of wrist was faster than unskill one's. In view of the results so far achieved, in order to do Pas de chat ideally, player has to get jumping power after doing Plie enough and make duration of a flight long with adquate knee angle and acute jumping action and minimize body shaking(back and forth, left and right). Also we can consider players can do well when they are trying to raise their body weight to up by using whole body with their wrists as it is seen from wrist velocity. I consider that we can provide more professional and more systematic action information of dancers if we develope subjective and acute evaluation model throughout professional's systematic observation. Also with many element of these result, if we research connection about downward vertical power and Knee angle by using force plate. I suggest that we can raise 1 level of action analysis with synergy effect if we improve our understanding about action with connection research of gymnastics and dynamics.
