On a side note, the new chapters that I’ve wrote so far are:
- Neural aspects of strength training
- Training tools: using weight releasers
- Training tools: using jumpstretch bands
- Training tools: kettlebells, boards, boxes
These are completed, I only have to have them edited. I’m also working on a chapter detailing how is hypertrophy stimulated.
Now, on to the ongoing discussion… I personally like autoregulatory training. I’ve been using it in the past and even designed an autoregulating powerlifting program a while ago.
However one thing that I’m not sure of, is the acceptable drop-off margin. In fact, in my own autoregulating training when there is the slightest drop off, that’s when the exercise stops. Which takes me to the 3-6% drop off zone advocated by DB Hammer. To me it’s wrong to use the same margin for all types of work. For example a 6% drop off during maximum lifting will surely not have the same effect/impact on the CNS and structural system than a 6% drop off from low-intensity lifting. In the first case the volume will be relatively low so the musculoskeletal impact will be insignificant and the CNS will take a huge blow. In the second case we’ll have the opposite effect, the muscles will suffer from a lot of micro-trauma from the high volume of work, but the CNS will be relatively unaffected.
So even if we have the same drop off margin, the recovery time required will be completely different in both cases since the CNS recovers at a much slower rate.
Same could be said with sprinting. Do you honestly believe that a 6% drop off in maximum speed work (60-80m for example) will have the same impact than special-endurance with a 6% drop off? Is the later even safe to do without risking injury?
Then we have the issue of the number of exercises. A 6% drop off with 2 exercises will not have the same impact as a 6% drop off with 4 exercises. Let’s not forget that CNS fatigue is cumulative. So a 6% drop off in 4 exercises could actually mean a 20-30% drop off in neural efficiency. The effect can be even worst if the exercises target the same area/muscles/movement pattern. In that case, not only does the CNS stress is increased over the 6% barrier, but the stress on the muscles is too.
And is the 6% drop off margin even acceptable for any sportint activity? Since DB give the example of a baseball pitcher, we can believe that this is his assumption. Well, how does that work with precision sports like gymnastics, figure skating or even golf? Will the player hit his wedge until he loose 6% distance? From experience, this would mean 6-8 hours practices (I’m been a competitive golfer in my day). And can we even say with precision where the loss of performance comes from? Fatigue, CNS fatigue, technical mistakes, dehydration etc.
I’m not saying that DB’s autoregulating methods are wrong. However he doesn’t provide enough information to use this method correctly. And before accepting them , we must question their logic.
