The purpose of this study is the impression of middle school men weight lifters to analyze kinematic behavior training coaches and athletes will be required to provide basic data. First, at phase 2 that belonged to the second pull phase, there was the shorted time required (0.36±0.04 s). Second, COM position was the biggest move in the vertical direction and especially, at event 3 and event 5. Third, there was the fastest move of COM velocity in the vertical direction and at event 2. Fourth, bar-centered position moved 0.19±0.06 m at event 2, and moved 0.17±0.04 m at event 3 forwards and backwards. Fifth, there was the fastest bar-centered velocity at event 3 that knee joint showed the maximum extension. Sixth, in relation to upper limb angles, shoulder joint showed the lowest angle at event 3. Seventh, in relation to lower limb angles, hip joint, knee joint and ankle joint all showed big angles at event 3 and 5 and especially, ankle joint showed the biggest angle at event 3. Eighth, out of upper limb angles, shoulder joint showed the fastest angular velocity at event 3. Ninth, in relation to lower limb angular velocity, hip joint and knee joint displayed the fastest angular velocity at event 2, and ankle joint displayed the fastest angular velocity at event 3.
