I intend to analyze the performance of 29 distance national throw substitute players(men and women) for the national team to show how physical strength and physique have an effect on their performance. By using SPSS/pc Version. 12.0, Mann-Whitney and Kruskal-Wallis verification, Spearman's ranking correlation factor and Stepwise's multitude recurrence analysis, I analyzed the interrelation between the performance level, physical strength and physique of shot players, discus players, javelin players and hammer players who were selected as substitutes in 2006 and 2007 consecutively. Conclusions are as follows.
1. Male discus players show greater height, chest girth, lower limb length, upper limb length and stretch of arms than hammer players while javelin players show the least. Female shot players have the greatest body weight, chest girth, waist girth and left and right calf girth.
2. There is no significant difference of strength factors in 30m run, long jump, hop step jump, shuttle run, side step test, shot put, squat, power clean, bench press.
3. Forseeable performance factors of male players are height and right calf girth (physique factor) and for women players bench press (strength factor) which play an important role in affecting performance.
