CURITIBA, Brazil – Amanda Nunes has battled issues with fatigue in some of her UFC bouts, but she believes she’s found the answer ahead of the biggest fight of her career.

Nunes (11-4 MMA, 4-1 UFC), the No. 6 fighter in the USA TODAY Sports/MMAjunkie MMA women’s bantamweight rankings, battles No.1 ranked Miesha Tate (18-5 MMA, 5-2 UFC) for her women’s bantamweight title at UFC 200, which takes place July 9 at the new T-Mobile Arena in Las Vegas. The main card airs on pay-per-view following prelims on FOX Sports 1 and UFC Fight Pass.

Nunes was in attendance at UFC 198 this past Saturday. The event, which took place at Arena da Baixada in Curitiba, Parana, Brazil, had the third biggest crowd in UFC history and the biggest in the organization’s history of events in the county.

Despite the huge crowd and raucous atmosphere in her home country, Nunes told MMAjunkie she was happy to be on the UFC 200 card instead.

“This is a very good card,” Nunes said of UFC 198. “It’s a huge, huge show in Curitiba. I’m OK with (UFC 200). I’m OK being on that card. I think it’s going to be one of the best shows. I’m going to be ready to take the belt. I’m going to be the new champion that day, and it’s the only thing I’m thinking of right now.”

Tate captured the belt with a fifth-round submission victory Holly Holm at UFC 196. Her ability to continue coming forward for five rounds has raised some concerns for fans question Nunes’ stamina due to past performances.

Nunes, however, said she has isolated the issues causing her fatigue and said she will carry those lessons into the title fight.

“My last fight was three rounds,” Nunes said. “Everybody thinks I’m not fighting three rounds. My last fight was three rounds. With five rounds, I want to surprise everybody. Do you know what I mean? I want everybody to wait for the final rounds. For sure, I’m going to fight five rounds. Whatever I have to do to finish that fight, I’m ready to do.

“Now I take care of my breathing. I think I had a little problem with how I focused on breathing in my fights. Now I’m trying to fix that. I go to yoga and do a lot of concentration to work on my breathing now. It’s the biggest thing, and I have to fix it. I’m getting better, though. The last fight I did it well, and my next fight I’m going to be 100 percent.”
