Illustrated below are the trajectories of the best ranked snatches, places 1-9 ; both male and female 69kg lifters at the 2010 world championships. This is the only common category of men’s and women’s Olympic weightlifting. Each placing male vs female was compared, ie 1st place(male) 1st place(female)

The specific lifters that went with each graphic were not identified. This is consistently the case with “scientific papers”. I was curious to know who was who, as a coach studying technique it is important(I had a need to know). It would seem rather straight forward to look at the results of the 2010 worlds, and figure out placings. The official record did not jive with the data(wt of bar in kg and the age of the competitor). It was only when I compared the data of wt lifted with the age of the competitor could I zero in who was the lifter. The rankings go from left to right, top to bottom. 1st place is the top left graphic.

Lifters disqualified for doping (Liao & Miculescu) and those who bombed in the CJ(Razvan) were included in the placings. Christine Girard was not included with a 104kg snatch because she lifted in the B grouping. Similarly not included in the mens category there was Triyatno in the B group who snatched 146kg and finished 3 rd overall.

The 1st place Shimkova RUS jumped forward in snatch. There were several lifters who did not move the bar rearward at liftoff, notably Miculescu who had the 3 rd highest snatch. In the majority of the 18 lifters the bar never went forward of the vertical starting point. Interestingly Liao CHN after liftoff had a nearly straight vertical pull through the whole motion.

Except for the 1st graphic, the names of the men are labeled on the right, women on the left. On the 1st graphic the men are Binay and Liao.
