English summary of Tyazhelaya Atletika. Ezhegodnik 1983 (Moscow: Fizkultura i Sport, 1983), pp. 10–16: the text is paraphrased, not translated; data tables are given in full with English labels; figures are the original images.

Material

Film analysis of three snatches by Yu. Zakharevich (100 kg class; height 178 cm, foot 28 cm): 188 kg (1st attempt, record), 192.5 kg failed (2nd) and 192.5 kg world record (3rd). Frames refer to the film sequence, positions to Figs. 1–2; phase times, speeds, angles and bar positions are in Tables 1–5.

Film sequence of Zakharevich's snatch
Film sequence (kinogram): Yu. Zakharevich performs the snatch — twelve frames from the start, through the pull, the explosion and the squat under the bar, to the recovery with the bar fixed overhead.

The 192.5 kg record lift

Bar trajectories in three snatch attempts
Fig. 1. Bar trajectory in the snatch — 188 kg (successful), 192.5 kg (failed) and 192.5 kg (successful), with bar speeds and horizontal displacements. p.v. — full leg extension in the first phase of the pull; k.p. — end of the knee rebend under the bar; k.o. — end of the support phase after the explosion. “+” — bar fixed, “–” — bar not lifted. Numbers 1–11 on the right-hand trajectory are the bar positions.
Stick figures of body segments in the snatch
Fig. 2. Movement of the athlete's body segments in the snatch, with joint angles in degrees. Numbers 1–11 are the positions of the body segments; the dashed line shows the average position of the segments (for other lifters).

* The source prints “185+”; the text, Fig. 1 and Tables 2–5 all give this attempt as 188 kg, so the last digit is evidently damaged (read 188).

For the successful 192.5 kg lift the article text gives the trunk angle after the knee rebend as 57°; the table prints 55°.

The original prints this table simply as “Table”, without a number; it is the fifth in the series.
