I have a couple of programming and theory questions about olympic lifting in general that I would like answered.
I read this article which got me interested in programming:
So it basically said that Anatoli Chernyak, who was a weightlifting coach in russia in the late 70s, had made some statistics of weightlifters and found a good correlation between deadlift and squats and snatches and C&Js. Basically if you have this strength in the deadlift and squat, with good technique you can expect these results in the C&J and snatch. You get the point, or just read the article.
An oly lifter can according to Chernyak be expected to Snatch 64-66% of his squat or 38-42% of his DL, whichever is lower. And he can be expected to C&J 80-84% of his squat or 54-56% of his DL.
The optimal ratio for the snatch between DL and Squat would be 1.52-1.74.
The optimal ratio for the C&J between DL and Squat would be 1.43-1.56.
(i corrected the original which had flawed calculations in it but showed roughly the same ratios)
These are alot higher ratios than most powerlifters, especially elite ones, typically strive for. Powerlifters are, according to the article i linked, looking for a DL/Squat ratio of 1.25 and in my own experince this ratio moves towards 1.0 with increasing weight and level of the lifter.
Now powerlifters spend time deadlifting, squatting and benching, while Oly lifters spend time back squatting, front squating, overhead squatting and oly lifting, but rarely ever deadlifting (from what I understand). I guess one could say the deadlift or a version of it is part of both C&J and the snatch but at lower weight, more explosive and different stance and grip, so not specific to the deadlift. This leads to some questions:
1. With this much squatting and this little deadlifting, in comparison with the powerlifters, how can the ratio of DL/Squat be so high in weightlifters compared to powerlifters?
My next question is about a specific athlete and his stats: Hossein Rezazadeh, world record holder in the C&J and the total in the +105kg class
Career bests (stolen from wikipedia)
Snatch: 213 kg
Clean and Jerk: 263.5 kg
Total: 472.5 kg
If we use Chernak's statistic we see this:
His snatch required a squat of between 323-333kg and a DL of between 507-561kg
his C&J required a squat of between 314-329kg and a DL of between 471-488kg
In other words reasonable squats for and completely unreasonable DLs (world record is around 460kg).
At one point after his carreer Hossein Rezazadeh was thinking of trying his hand at powerlifting:
His coach gave his stats (2009)
859 pound squat (=390 kg)
837 pound deadlift (=380 kg)
These stats could possibly better than when he took the world records because he was most likely working for that powerlifting event prior to that.
2. What is the cause of this discrepancy? Are the statistics not viable for the heavyweights or are the deadlift requirements made by Chernak just plain wrong for all lifters?
Ty for any input. The point here is to overanalyze. Feel free to tell me how your stats in these 4 lifts correlate to the statistics Chernyak gathered.
