- International Amateur Athletic Federation scores, based on the personal best times of each event for 100-m and 400-m specialized sprinters were used as parameters for sprint performance. Italic values indicate a significant correlation (P < 0.05) between leg bone length variable and sprint performance in 400-m specialized sprinters
