Chronotypes are more related to sleep than training. Since growth happens during recovery, sleep should be as important as training and nutrition but unfortunately is waaay underated as a performance/growth enhancer. Just look to any web forum regarding sports and you will rarely find someone asking about sleep improvement. Everybody talks and asks about training, nutrition and supplements, but not about sleeping.
If you would like to correlate Neurotypes and Chronotypes it has to be under the light of neurochemistry. CT has talked a lot about it regarding Neurotypes, so I guess that if you take a look at the optimal hormonal time to sleep you will have YOUR answer.
Why do I place “your” in capital letters? Simple. Because the time and type of training will depend on your needs and goals.
For example, let´s take someone who is a Dolphin Chronotype who has trouble to get deep sleep, wake up unrested, feels tired during the day but with a spurt of energy during the evening
In this case what would be the perfect time to train early morning, noon, or evening?
I would say that any of them…regarding your prorities and needs
If you wake up unrested, low energy during the day and you have a daytime job that requires you to be fully awake and assertive I would say that best time to train would be early in the morning to get energized and awake. In this very same case it would be a mistake to train late since you naturally have a spurt of energy, you could get more energized with training, and then having troubles to fall asleep. Obviously next day you may feel terribly tired.
But if you don´t have those needs and can afford the luxury of getting asleep late at night, and also you have the priority of increasing your training performance; then the best time to train it would be in the afternoon to take advantage of the energy spurt.
With Lions would be something similar, if the priority of someone with that chronotype would be to take advantage of being sharper in the morning and having lots of energy to improve his business, generate new ideas or projects, thinking on novel approaches to solve troubles, etc. Then training may not be the best choice in the morning unless that the energy and clarity of mind gets even better with training. But even in that case, if your job or activities also require being assertive and energized in the afternoon, it may be a good idea to train at noon.
Your question is an interesting one but I think it has not just one answer. At least that´s the way I see it. It would be interesting to see CTs answer to your question
On YT there is a video of Rhonda Patrick about it. It’s called Chronotypes: Your natural propensity to be an early riser or night owl | Matthew Walker
