HOW THE BODY ADAPTS TO TRAINING?! The Good, Bad & Why Behind Adaptation to Training

Understanding how and why changes have occurred to your physiology is incredibly important to reassess and establish a path forward in your training. In this video, I take you through the chronic adaptations that occurred in my data and how that impacts my ability to take in, transport and utilise oxygen plus the overall impact on performance.

Excellent video - very interesting details that help understanding responses to training without spending time and money. I feel going through a very similar loop from running to cycling

Hi.
Love the channel so far. Evidence based!
When training for a marathon, if I am putting let’s say any given milage/time dedicated to training per week, is there any advantage to working at a lower HR zone, other than possible injury mechanical injury?
To rephrase, if I’m running 50 miles a week, a race is HR 155-170 ( I’m 45), if I can run all that milage at zone 3-4-5, is there advantage to running zone 1-2? It seems like the SV, and all other CV benefits would be even greater the more I do at a higher HR.
Thanks

If you did all that mileage Zone 3 and above you'd burnout super quick. That's the first issue. Second is the adaptations that we are looking for in terms of at the muscle (use of oxygen) and improving cardiac responses come from either long slow intensity (usually 56-70% VO2max) which is Zone 2/base kms for most people then also from near VO2max intensity.
The lower intensity enables you to gain aerobic adaptations plus allow you to build muscular endurance in a way that the body can recover from adequately for the next session. Most athletes go wrong by going too hard in their "slower" sessions and not hard enough. What this ends up doing is limits the stimulus we need to effectively try to constantly improve threshold in the middle. But you plateau quickly and struggle to continue to improve because threshold can only keep improving if you total aerobic engine (i.e. VO2max) is also increasing.

Can you do a video on endurance adaptation science ? As I am going into military camp which need fitness test
