The athlete places his feet in the starting position such that the bar is over the vertical projection of the metatarsal phalangeal joints. The pelvis is slightly higher than the knee; the shoulder girdle is “taut” and is positioned over the bar.
The trunk is straight and is leaning at an angle of 55°. That is a natural position. The line of sight is directed forward and down (figure 1, position 1). The athlete does not employ a preparatory action; but, immediately begins to lift the barbell after assuming the previously mentioned position (in figure 2).
The lift up to knee level is carried out primarily by extension of the legs. The sportsman holds his trunk in approximately the same position (figures 3 to 5).
The knee angle is approximately 150° (figure 5) when the legs are almost fully straightened. From here the athlete continues to lift the barbell by straightening his trunk. The pelvis tends to tilt slightly as the knees bend to an angle of approximately 135° (figure 6, position 6). The athlete has completed the first phase of the pull and is prepared to perform the second phase, the explosion.
At this moment the barbell is level with the lower one the third of the five and has shifted towards the athlete by 10 cm, relative to its initial position. The speed of the barbell is 1.2 m/sec. The athlete straightens this trunk faster than he straightens his legs (figure 7) as he performs the explosion. As a result, the shoulder girdle shifts behind the vertical line, relative to its initial position.
The athlete’s center of gravity shifts significantly backward, at the conclusion of the explosion, because of the large inclination of the trunk. During the second phase of the pull, the barbell is raised initially 2 cm closer to the vertical line relative to its initial position; then it shifts upward and backward (figures 8, 9, position 9). Speed of the barbell at this instant is 1.6 m/sec.
The descent into the squat position begins. The athlete raises his elbows upward, then as the legs, and shifts the trunk down. It has the raises his feet from the floor the sportsman rearranges M. 7 cm backward and slightly to the side. The back begins to arch (figures 10, 11).
In the squat position, sportsman has arched his back; the elbows are forcefully shoved forward, and the head is straight. The trunk is almost vertical; the projection of the center of gravity of the barbell is in the middle the feet (figure 12, position 12).
The athlete lifts the barbell to a height of 105 cm (his height is 168 cm). The barbell dropped 34 cm during the squat under and was fixed at a height of 71 cm. During the entry into the squat, the barbell performed a large hook after the explosion; it shifted 20 cm backward relative to its initial position which made it difficult to secure the barbell in the squat position.
The back maintains its original disposition with the arch in the lumbar area. The athlete rises from the squat position and assumes the initial position for the jerk (figure 13, position 13).
Kangasniemi performs the jerk from the chest with precision. The, preliminary squatting reaches a depth of 18 cm (the knee angles are 110°); the trunk is vertical; the arms are almost horizontal; the entire weight of the barbell is resting on the chest (figure 14, position 14).
The upward thrust of the barbell is carried out by straightening the legs with the feet flat on the floor and a subsequent rising onto the toes (figure 15). The barbell shifted 1 cm during the half squatting and by 1 cm during the jerk itself.
The pelvis and trunk are shifted under the barbell after the jerk by rearranging the feet (figure 16). The knee angle of the leg shifted forward is obtuse; the shin is in a vertical position, and the knee of the leg shifted backward is slightly bent. The support is equally distributed over both the feet.
The athlete fixes the barbell overhead by straightening the legs and re – arranging the feet (position 17).
