The times in motion for the above 100k snatch are within the average of most lifters. The clean time was a little slower than the snatch, possibly due to her controlling the pull a little more in the clean than in the snatch. Her jerk 0.47 seconds, better than the .5 second average, even though she had trouble controlling it.
The squats selected reveal the diminishing returns concept where the slower the squat the less it will equate to the lifter’s clean & jerk. The 150k back squat at 1.15 seconds is equal to 143k @ 1 second. 143k @ 1 second is equal to 123k clean & jerk. This particular squat is in equilibrium with her clean & jerk. The 170k back squat was equal to 123k back squat @ 1 second and that is equivalent to 105k clean & jerk. As the weight in the back squat increases and the times become slower, then equilibrium is lost at some point and diminishing returns set in. I believe equilibrium is held at times of 1.5 seconds or faster. Slower times can throw the lifter out of equilibrium and cause subsequent sessions to be less effective, due to the unnecessary overloading.
In essence; heavier slower squats which do not equate to the lifter’s clean & jerk become powerlifting type squats instead of assistance lifts. The excess overloading, stress and fatigue between assistance lifting and powerlifting will have an impact on the lifter’s ability to physically recover in time for subsequent sessions and progress the clean & jerk, if such practices persist.
