Everything is connected. Impossible to isolate one system of the body, when one is working then all are working. You may designate a workout as having a metabolic emphasis or a neural emphasis, but there will be profound effects on all systems of the body not just the “targeted” system. I particularly enjoy swim coaches who have all these neat color coded charts with workouts in very specific heart rate zones designed to target specific energy systems – the body is so much smarter than that, it is always seeking to adapt and preserve homeostasis. It is IMPOSSIBLE to isolate one energy system or for that matter one system of the body whether it is neural, cardio vascular, muscular, or endocrine hormonal. Recognize that there is always a spillover effect, for example 3 x 150 meter sprints at 95% with full recovery will maximally tax all systems of the body. You will be working at greater than VO2 max during a portion of that sprint. Understanding this has great implications, as a coach it took me too long to figure this out. You will find if you grasp the idea that you will need to do less “fitness” oriented training when you realize the cumulative effect of all the components of training.

Vern is confusing skills coaches who go beyond their area into the S&C area. Most qualified and expeienced S&C coaches understand that the athlete is treated as a 'whole'.
Carl Valle is one of the better S& C coaches for swimming. I doubt he would be stupid enough to ISOLATE.
