This study was conducted to find out the relationship between skin temperature and clothing temperature in body parts. Four different kinds of fabrics were used in this experiment. These fabrics were a (Ny/Spun, 81.8/18.2%), b (Wool/Poly/span, 50/45/5%), (Wool/Ny/Span70/25/5) and d (Wool/Poly/Span 45/45/10%). The subjects skated at indoor ice rink where the length was 111.12 m, the temperature was $11{\pm}1^{\circ}C$ and the humidity was $70{\pm}10%$. The four an male professional skaters speed was $17{\pm}1$ seclm/lap. Physiological parameters were skin temperature at 4 body points (chest, upper arm, thigh, leg) and clothing temperature at chest was measured every 15 second. Experiment protocol was as follows: resting before skating (5 min.), skating (5 min.), and resting after skating (10 min.). The results were as follows; The mean skin temperature by fabrics shows b > a > d > c. The mean skin temperature began to decline little by little as soon as the subjects entered the indoor ice rink. After they rested for five minutes, they started skating and the mean skin temperature declined widely. After skating, the mean skin temperature increased step by step. It maintained the similar temperature. The value of skin temperature at body points shows Leg > Chest > Upper arm > Thigh. Because of the characteristics of skating uniforms, the skin temperature of the leg is the highest. The skating uniform was designed to have a protective portion in the leg. The chest produces the highest temperature in the body. The comparison of difference values in skin temperature show Thigh > Upper arm > Chest > Leg. While skating in a cold atmosphere, the largest difference value is clothing temperature. The clothing temperature is lower than the skin temperature during skating. The difference value of clothing temperature is larger than the skin temperature of the chest.

The purpose of this study was to examine the effects of the result of hardship performance of the propulsion speed on the flying carmel spins during a Figure Skating. The subjects were five the korea national representative players. Kinematic variables were analyzed 5frame of the excursion phase by the three-dimensional motion analysis system(60Hz). The obtained conclusion were as follows: In this study, during the propulsion classify two groups as "type I" the acceleration patterns S3, S4 and "type II" the uniform velocity group S1, S2, S5. The results of percentage comparative analysis between type I and type II can be summarized as below: the height of jump(24%), the height of COM(25%), the maximum speed of Roundhouse Kick(21%), the judging technical score(18%), the flight time(13%), the velocity of spins(4%), the distance of flight(-6%) Analysis of the results on performance variables, the velocity pattern of the type I showed comparatively excellence than that of type II.

The purpose of this study is to develop and examine an in-line skating uniform that is also suitable for everyday wear, through research on the dressing needs of skaters. The results of this research are as follows: when asked about the garment, ordinary clothes were more inconvenient than professional uniform. In the case of the upper garment, the skaters who dressed in ordinary clothes felt the most inconvenience in the part of sleeve, back side of bottom and width. The skaters who dressed in professional in-line uniforms felt the most inconvenience in the part of neck girth, of sleeve, back side of bottom. In the case of the lower garment, the skaters who dressed in ordinary clothes felt the most inconvenience in the knee, crotch and hip. The skaters who dressed in professional in-line uniforms felt the most inconvenience in the hip and crotch. Damage due to wear was shown up the hip, knee, side of thigh and shoulder. The answer rate was high that the ordinary clothes usually wore out and the uniform used to tear out in the form of clothes damage. An appropriate sample pattern was made up, based on the problems revealed in the results of the questionnaire analysis. Evaluation of samples was used linear Measurement (5 point preference scale) by organized with 15 male and female's subjects group and 12 observer group.
