ACL injuries do not happen in a void. People sustain injuries when their infrastructure is unable to manage a specific set of physical circumstances. To describe the mechanism of the injury without the context of the person and their level/type of sport, is to miss valuable insight. In sport, we prepare the person, to the best of our understanding, to meet the physical demands of that sport. We do not just work to prevent one particular injury; we prepare athletes to navigate the total sport physical environment. By "we" I mean the coaching and support staff -- specifically the athletic development staff. Athletic development (AD) coaches prepare athletes through the development of physical literacy and movement competencies via movement progressions. It is more than strength, power, agility; it is the acquisition of knowledge, skills, abilities and behaviors to manage themselves within the entire sporting environment. At the higher levels of sport, AD coaches coordinate wit...

I often think that the o-lifts with a barbell work sort of like a trebuchet, with its multiple axes and the complex system of weights rotating around each other, vs. a fixed catupult.
We can discuss on Saturday and I will bring a few KBs. But this is based on my limited experience with Olympic Lifting, but my extensive experience with KBs.
If you are doing a high rep snatch, then it is a swing snatch, that is you allow the bell to swing back. You pop or "yank" at the optimum time to take advantage of the momentum of the swing. This pop or yank/shrug is what is similar (imho) to the 2nd pull.
Now, there is another style of swing or swing snatch that focuses on a tighter arch and a violent hip snap that projects the bell more outward instead of upward. It relies less on the timing I discussed above. The arms in the swing performed this way are straight. So, it doesn't carryover to the swing snatch as well as the above. The carryover to this exercise maybe more like a powerlifting style deadlift.

The swing as I teach it is identical as the KB snatch in terms of what you do with your lower body; there is a pop, you just don't complete the movement in terms of going overhead.
Like I said to Tracy, we can discuss on Saturday (Dan I take it you are Dan Thacker and we've met). I won't discuss during the actual workshop (unless asked) but will be happy to stick around or come early to talk about it.
The only reason I think it should be discussed is that there are people who think the KB lifts are competitive with Olympic Lifts in terms of building explosiveness. I don't find this to be the case. KB snatch and swing are great conditioning exercises and are far less technical than the Olympic lifts.

My friend Steve Cotter wrote an article for the Crossfit Journal a few months ago outlining the differences in some "Styles". Here is a link to this blog, with a link to the article:

Thank you for the discussion! This is exactly the type of dialog I want to have on Saturday--especially for people who are Crossfitters. I recently found the Steve Cotter article (Google) and found it very informative. But thank you, Catherine, for putting up the link. I think others will find it interesting.
There are many differences between using a KB and a BB. Both can be very beneficial, but the athlete needs to be aware of these differences. What one does with a KB or DB, may not easily and automatically transfer to the BB.
