An investigation into the effect of psychological stress on performance during a Brazilian Jiu Jitsu competition

My thesis is based on a data collection with a qualitative metodology.
I have already started to write an introduction that should be reformulated. Because I’ve drawn on information from scientific articles, but I’ve done a poor job of resourcing the information noted in my introduction. (I’m attaching all the corresponding articles).
Then for the methodology I need to clearly explain my approach, which is a qualitative study in the form of interviews. I interviewed 10 participants with open-ended questions. My sample was 7 male and 3 female, with a minimum of 3 competitions of experience. I asked all levels and no importance was given to age or years of experience.  As for the results, that’s a part I’d have to take care of because I’d have to listen to each interview again and make a table with all the answers. However, on the document I’d like you to help me develop the point that women tend to have more cognitive anxiety and less self-confidence than men. I’ve noted an article that explains this. You just need to explain it and make the references.
Then, for the discussion, I’ve already gathered information that I considered important for my study, which I wanted to compare with my results. That’s why, as you won’t have the results, I’d just like some help in making a selection of what’s relevant or not. Furthermore, most of this information is unsourced, so I’d just like some help in sourcing the articles I’m adding as appendices.
Finally, if you can help me start a conclusion I could also add my information with the interview results.
I hope my instructions are clear. Thank you in advance for your help.
