Conclusion The angle of hurdling An angle At the begining part of the game, (take off), Shan has got lower points due to not enough angle of his hip (160.8, 163.3 : 176.3, 175.1) and knee (51.8, 87.8 : 80.4, 79.4) even though he has taller height Shon has bent his body position too much, which reduced his speed of hurdling when attacking, both of two player, Hwang and Shon hadn't made a big difference and had showed pretty much stable body position Hwang hadn't utilized his angle of knee at the fifth hurdle, However Shon had represented a nice angle of hurdling. At the 'Dip Part' Shon had higher angle, which is 13.1. This had connected to the jump movement. It'd be more effective if you bent you waist and decreased dip angle and hip angle to increase the inertia speed. At the part of Touch Down which is the last part of the hurdling process to be combined with the speedy running. The angle of hip and knee is very important. As far as an hip angle, both of the player, Hwang and The body balance As a result of research through two player's the forth and fifth average body center position, compared to Hwang, Shon performed 5.6 degree of an angle at the take off part, attack part 4.7 degree of an angle. and had showed 2 degree lower at the touch down part. At the dip part had recorded higher by 3.1 degree when taking off and attacking that require you to increase you speed, Shon had the lower body center, the reason is Shon had a hard time combining his speed with hurdling and he has a tendency to make a short pause right in front of each hurdle in order to move on to the next jump. At the dip part Shon needed to bend his waist more to decrease the stay in the air time when hurdling, At the touch down part Shon's knee angle has been bent that caused a trouble to move onto the next speedy running position after hurdling part. Shon is required to make up for the week points. The body balance and speed As a result of both players, Hwang and Shon, the average declination result of hurding body center speed, at the take-off part (499.2), attack (422.2) Dip 384.6, touch down 313.4 Shon had showed lower points. Hwang had showed the fastest center speed during take-off part and when attacking, meanwhile Shon did during touch-down part and dip part Hwang has a great ability to combine the fastes speed with hurdling, however Shon has a trouble with connecting speedy running to hurdling and taking advantage of inertia speed. This explains why Hwang has performed a faster hurdling at the beginning part, meanwhile Shon is fater at the last part of the hurdling. Hwnag has a tendency to utilize his speedy running at the beginning part of 400M hurdle (from the first hurdle to the fifth hurdle), but Shon had a habit of not making a difference between the beginning part and the ending part of hurdling, that's why Shon had recorded slower body center speed than that of Hwang. (reference the picture 7.8) Shon needs to increase the speed at the beginning and to train to be strong with staying power at the ending part of the hurdling. As a whole, based on the research on the angle and the speed of Hwang and Shon, Shon didn't apply an angle to the hurdling, meanwhile Hwang takes advantage of inertia speed combined an angle with the speed. Suggestion Based on the research materials of the degreee of an angle of hurdling, the movement from up and down of the body balance and body center speed. These theories should be applied to Shon for him to contribute Korea track field of sports by complementing his good points and week points.

Conclusion KOT athletic has been taking advantage of super physical conditions when hurdling. However his physical conditions sometimes cause to reduce the speed w hurdling because his movement of both arms are distant from his body and his habit of bending his lower part of body when hurdling also bothered his hurdling speed. Suggestion I've been researching two track players who represent Korea team to come up with this theory, but in the view of improving present situation, it'd be more effective to sample more players.
