Yet, what passes for knowledge in academia is stuck in the static strength era of weightlifting: more muscles, short stature, more static strength translate to bigger weights lifted... The belief short weightlifters have the advantage; and, lifters with thicker muscles and proportionally more myo-filaments will dominate the sport are myths; yet, are still passed on as fact today.
Yet provides stout and muscular Best Korea athlete as photo example with this statement.
Classic Charniga contradiction.He's not entirely wrong though. Anyway China, Venezuela and so on are producing well muscled lifters who are winning stuff in the year 2024.

On the contrary, the power of the thigh muscles is more effectively transferred to the feet when the heels raise, i.e., triggering an inter-compensation of energy to the support. This reflex engages the biarticular gastrocnemius, a thigh muscle; which in turn, results in a speedy extension of the foot; delivering more energy to the support than is possible from the nearly extended knees (Schenau, 1989).
Debatable regarding the premature heel rise in the pull phase. This can lead people to believe that this is unnecessary to correct because Charniga says that this is okay without emphasizing and ensuring that balance in the athlete-barbell system is maintained over the area of balance.
I think neither option is inherently more or less efficient but don't have data on this.
IMO it depends on the athlete's build and physiology, which ultimately determines how much tradeoff can occur between the different joints in order to provide the minimal loss of vertical impulse in the middle of the pull and maximise the increase in vertical impulse from the first and second pulls.
For those who have particularly weak knee/hip/back strength, this is probably true (think Peng Cuiting). This of course plays into Charniga's bias of his beliefs about the ideal mechanics of the lifts and his typically minimalist approach to squatting and pulling exercises. On the other hand, training systems that traditionally emphasise a large amount of squatting and over-the-bar deadlifting strength (e.g. Russia, USA, UK) may have better force transmission through a flat foot.
The way I teach people is probably more biased towards the flat foot than the heel raised start of the second pull, but as long as someone is well balanced through the lift, with the bar moving relatively vertically (minimal swing), consistently I don't care.

The salient skill – of – strength in weightlifting is the ability to lift a slow-moving barbell. The maximum vertical speed of the barbell recedes along with the increase in its weight. Weightlifting involves a complex interplay of internal work, which is the mechanical energy produced to move body segments and the body as whole; and external work, or the mechanical energy produced to move the barbell (Latash, Zatsiorsky, 2016)... That is besides the fact that since the aim is to lift a maximum weight; the speed of the barbell recedes as the weight increases. Consequently, the speed of muscle relaxation and the lifter’s speed of movement are the crucial speeds; not the barbell speed
This needs to be emphasized to weightlifting coaches who are obsessing over velocity based training and focusing on improving their peak velocity at sub and maximal weights, rather than utilizing it as maybe a tool to train lifting submaximal weights at maximal velocities. The inability to fixate the barbell moving at less than "normal" perceived speed is a big issue I see amongst lifters transitioning from beginner to intermediate and even elite levels of movement/weights.
Yes. Tempo snatches (enforced either by counting or a metronome) can help with this to some degree. No hook or high hang snatches too.
There is a time and place to work on high velocity training certainly, but I find it's probably best suited as GPP work, or for lifters who already are comfortable making lifts at slow velocities.

Furthermore, the curves (cervical, tyhoracic, lumbar) in the human spine are adaptations to vertical posture (bipedal locomotion) and as such are poorly suited to strain with the trunk close to or at a horizontal disposition.
I find Charniga's emphasis on vertical squatting just as problematic as the NSCA type of squat where nearly vertical shins are encouraged, because Charniga's style of squat involves very little hip flexion. The truth lies somewhere in the middle here where we want to have relatively equal flexion of the hips, knees, and ankles while squatting results in better balance in the athlete-barbell system and adequate strain amongst all the muscle groups of the lower body.
I agree with you in terms of my bias at least.
To play devil's advocate, squats are a simply a preparatory exercise and so whether they are done in the knee dominant, hip dominant or "balanced" ways should depend on the rest of the training program and how it is performed. Certainly a program with only extremely vertical squats and a lack of hip/back strengthening work would make technical development very difficult.
In the end I think there are three types of lower body strength exercises that should be addressed
- Knee/quadriceps strength
- Hip extension strength with knee extension demand (largely glute/adductor)
- Hamstring strength
However that is achieved depends on the coach and lifter. Some might do vertical squats and pulls. Some might put an emphasis on heavy squats and good mornings or hyperextensions. Some might ignore the hamstrings entirely. There are many methodologies that have worked well enough to win gold medals.

Traps
Traps are also utilized a lot in supporting the barbell overhead which Charniga forgets.
Shrug is a cue, not a line of code. It can be used or discarded as necessary.
As for the support of the bar overhead, Charniga will probably say that a large muscular contractile effort is not required, simply support it with your shoulder stability skill, skeleton and elastic tissues /s

Very much agreed that the glutes offer little to the actual propulsion of the barbell. As Charniga wrote back in 2007 even, the glutes' role in the Olympic lifts is postural during the pull - to prevent the lifter from toppling forward during the pull phase. In my experience this holds up as well. Direct glute training has resulted in lifters maintaining better angles during the pull phase of the lift and avoid too dramatic and unnecessary change in trunk angle during the pull.
Glutes, adductors and controversially, the lumbar erectors all act in a quasi-isometric fashion in the first pull (yes, the erectors work concentrically too). I think this is why deep back squats are a good developer of the strength in the first pull, and why lifters will typically complain of sore adductors and glutes following first pull work or paused back squats.
In my experience, heavy and/or high repetition snatch/clean deadlifts seem to do little more for first pull positional strength than regular snatch or clean pulls (105% or less).
My conjecture is that with large weights, a major part of learning to snatch/clean deadlift more weight is simply minimising the hip extension demands off the floor. This is done by shifting the CoP and CoM backwards and flexing the spine. I see this from China quite often. Not inherently injurious thankfully, but it doesn't seem to strengthen the first pull outside of simply adding more general muscle/strength.
The ability to utilise that strength seems to largely depend on how much attention is paid to first pull mechanics in the classic lifts, particularly being patient enough to work in the Goldilocks zone of not too fast, not too slow velocity through the first pull.

Agreed but dismissing slower eccentrics and isometrics is a disservice to training variety and load management. Many athletes that I train who only bounce and freefall their squats tend to have anterior knee pain and absolutely no eccentric control. They are unable to put the brakes on the bar at any point in the eccentric phase. This is a useful skill to develop in my experience because I notice better maximal strength and hypertrophy development, as well as reduced tendon issues.
I think this is a theory vs practice moment. Certainly the ability to deal with fast eccentrics is important, but part of that IMO is being able to hit the brakes as you say and control the bar regardless of the speed. Chris Beadsley makes an argument that excessively slow eccentrics negatively impact muscular hypertrophy through poor recruitment and an increase in calcium-ion related fatigue. I'm not sure I'd go that far though.
I'm not a particular fan of very slow tempo squats (e.g. 3s eccentric) outside of motor learning for absolute beginners and quadriceps or patellar tendinopathy rehabilitation. Higher load squats and loads/accelerations that induce sufficient tendon strain are what is important for connective tissue adaptation.
Following that, what your squatting should look like depends on what the rest of your program looks like. Strength is not really a physiological quality, it is a measurement of an amalgamation of physical qualities. If someone does lots of heavy quick lifts into a deep squat (e.g. in a peaking phase), they might want to squat a bit slower down to reduce the risk of injury. Others will obviously need to focus more on elastic squatting, with a decrease in load. It just depends on the totality of the program.
