The purpose of this study was to investigate the correlation and deviation between 100-meter running performance in the track-and field event and factors of basic physical fitness. The 26 subjects who took the physical fitness test of 14 different event swere those mail students whose specific sports training event was short-distance running during the first semester, 1998 at the National College of Physical Education. On the basic of statistical anaysis with the Multiple Regression and Stepwise Regression procedures,there sults and the predicting formula are drawn as follows: 1.The testing results with erliability significantly reaches its level..(P<0.01). 2.The results of basic physical fitness tests have predicting validity to 100-meter running Performacne, Through the three steps, X09-side steps, X01-100-meter backward running and X02-standing long jump, the regression model becomes significant..(F=64.850, P<0.01) The multiple correlation coefficient R=0.9176 and the coefficient of determination R Λ 2 =0.8420 are obtained. Therefore, the predicting validity of these three factors reaches 82.2% of the tottal variable; the increment gets to 8.21% the predicting equations are made as following: The regression equation of original scores: Y=13.1495-0.229X09+0.0490X01-0.6801X02 The standardized regression equation: Zy=-0.4710X09+0.2519X01-0.2899X02
