The purpose was to examine the effect of different pitching approaches on accuracy and distance of ball-passing， and the relationship between upper body strength and accuracy and pitching distance in varsit softball players. Subject were females (N=13) and two of them were left handers. Physical characteristics were age (18.73土1. 91 yrs)， height (159.10士5.41 cm)， weight (57.38 ± 8.74 kg)， BMI (22.17士2.24 kg/M")， percent body fat (22.31土4.87%)， fat free weight (43.50土4.68 kg). Absolute grip and back strength were 31.03 ± 3.61 nd 89.99 ± 12.85 kg， respectively. Relatie grip and back strength were 0.55 ± 0.07 and 1.58土0.21kg/kg body weight， respectively. Sit-and-reach for 30 and 60 second were 21.55土2.61 and 37.45土6.62 times. significant difference (p
