This study is to compare and analyze variables of between athletes group and control group while sprinting 100 meters at top speed for male, selected 3 sprinter athletes and 3 non-athletes as a control group, analyzed the variables by three-dimensional imagery and visualization technique using DLT, the results are as follows; 1. In the matter of stride velocity, 0.25±.01sec is for athletics group and 0.30±.017sec is for the control group, in the matter of stride length, 214.33±7.51cm is for athletics group and 198.00±4.36cm is for the control group, so the athletics group is longer in stride length. 2. The angle of hip joint while landing foot is 134.17±1.47˚ for athletes group and 139.23±3.10˚ for the control group, the athletes group has less angle of hip joint. The angle of hip joint while leaving foot is 119.77±1.97˚ for athletes group and 140.20±2.46˚ for control group, the athletes group has less them. 3. The angle of knee joint while landing foot is 153.57±3.13˚ for athletes group and 160.10±3.73˚ for the control group, the angle of hip joint while leaving foot is 145.37±.91˚ for athletes group and 1150.03±3.47˚ for the control group, the athletes group is shown less angle of knee joint than the control group. 4. The angular velocity of hip joint while landing is 531.80±19.96deg/s for athletes group and -328.67±84.52deg/s for control group. The angular velocity of hip joint while leaving is 403.40±9.26deg/s for athletes group and -194.73±5.12deg/s for control group, the athletes group has faster angular velocity than control group. 5. The angular velocity of knee joint while landing is -207.73±20.54deg/s for athletes group and -153.53±3.96deg/s for control group. The angular velocity of knee joint while leaving is 62.77±.91deg/s for athletes group and 50.13±4.lldeg/s for control group, the athletes group is shown faster angular velocity of knee joint. 6. The lasting time from landing to leaving foot is .11±.02sec for athletes group and .18±.01sec for control group, the athletes group has longer lasting time. 7. The angle of leaning upper limb is 9.40±.44˚ for athletes group and 13.07±.61˚ for control group, so being more flexed is shown in the control group. According to above results, it is desired for athletes to develop records of athletes group and to train control group that proper stride length should be given to determine rather than try to increase stride length at discretion because stride length have an much effect on velocity, try to establish strong kick power with making narrow the angle of knee joint while landing and the width of up-and-down movements, improve lower limb muscular strength by lowering break, and put driving force on the front part of foot by shortening lasting time, try to be easy to rotate lower limb by decreasing the angle of knee joint and by increasing the angular velocity. The results agree with the theory that the moment of inertia should be decreased and the efficiency of inertia should be raised, the abdominal muscle strength seems to have close relationship with velocity, angle of hip joint and angular velocity of hip joint, the angle of knee joint and angular velocity of knee joint, therefore, it seems to need strong strength to drag lower limb by hardening abdominal muscle.
