다국어 초록 (Multilingual Abstract)

A study on the level and changing pattern of physique and physical fitness athletes of short track and jumping The purpose of this study was to investigate the level and changing patterns of physique and physical fitness in athletes of short track and jumping, from 1990 to 1994. Thus it was presented the basic valuable data for selecting new figures, keeping the abilities of excellent figures, and coaching with positive scientific method to all of the athletes in this fields. Furthermore these data could be used sources as standard criterions for the advanced studies in future.
The results of this article were as follows.
1. Physique
1) It was gradually increased in average height 180.8±3.40 cm, upper limb's length 77.6±5.97 cm and lower limb's length 96.9±3.57 cm at the factors of extend growth.
2) In 1994, it was decreasingly measured average chest's record 98.6± 2.31 cm at the factors of developed girth.
3) It was significantly changed weight 75.7±2.90 kg, subcutaneous fat 8.57±1.32 at the factors of volume.
2. Physical fitness
1) It was continuously increased in right grip strength 60.6±8.87, left grip strength 57.0± 6.26 kg, and back strength 179±17.10 kg in the case of physical strength for 5 years.
2) It was of the increase sit-up 37.0±3.49 times and pull-up 8.57±1.32 times in muscle endurance.
3) In power, measurements were gradually increased such as broad jump 270.3±10.93 cm, sergeant jump 72.7±1.43 cm, and 100 m run speed 11.39±0.36 seconds.
4) In agility, 10m shuttle run's average record was 9.4±0.27 seconds and the side step test's average score was 53.5±1.73 times, so this survey shows that the average record was continually increasing.
5) In coordination factor, 5 time-rolling's result was 11.3±1.55 seconds which was little increased.
6) Cardio-vascular endurance was shown the significant differences of the results among years and variation.
7) In flexibility factor, trunk extension average record was 65.2± 10.06 cm which was significantly progressed in each year, but trunk flexion's average record was nothing to change for experimental years.
