The purpose of this study was to investigate the levels and changing patterns of physique and physical fitness in national class athletes of short track and jumping, from 1992 to 1996. 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 1991, 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 continually increased in right grip strength 60.6±8.87 kg, 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 on the increased 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 279.3±10.93 cm, sergeant jump 72.7±1.43 cm, and 1001 run speed 11.39+0.36 seconds.

5) In coordination factor, 5 time-ruling’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 records was nothing to change for experimental years.
