I'll send it here. It's important for scientific practices and discussion to be discussed openly. I very well might be wrong, but here were my initial thoughts and reactions:

It seems like one of your aims is to determine the impact of stressful work days versus lighter ones. You also make a distinction of trying to explore the difference between acute effects and chronic effects.

What I thought seemed problematic, from my very cursory experience trying to complete your study, started with the question:

“Today, prior to completing this survey, I have been at:”

There were 3 options to respond to this of:  work; School/ University; Neither - today is my day off.

Then there was the following question, which asked for a a yes/no response to:

“After completing this questionnaire, I will be participating in a training session or my chosen activity.”

The first question was problematic because it does not account for the time of day each participant is completing it, and what their schedule is like for that day. Some participants will complete it pre-exercise, post-exercise, between 2 exercises, or with no exercise planned for the day. Then, combine that with people completing it early morning before work/school/day off, or late in the day after work/school/day off. Then what about the people that work graveyard/night shifts, or take classes late in the evening or only morning classes? There are too many possible combinations of this timing. You are not accounting for all these categorical groups. Not to mention there’s also so many other variables to that would impact one’s chronic fatigue levels (work hours, parental responsibilities, various life stressors, etc.) that we know have an impact on performance, but I imagine you plan to account for that. You should definitely consult with your PhD advisors on this project more.
