Powell uses Mullally’s breathwork before and after fights to recover and stay in control of emotions.
Powell, who fights in the same weight category as Great Britain’s two-time Olympic champion Jade Jones, said: “I’m always looking for how I can take control of the match and get the fight on my terms.
“You can’t do this without being able to control yourself and your emotions. Anthony’s support is helping me to do that and that’s the biggest competitive edge I can have in the run-up to the Olympics.
“I use his control breathing techniques to slow my breathing down. It helps to calm my central nervous system, so I don’t go into a panic state, start to shorten my breath or overthink.
“As a fighter I prefer to feel relaxed – that’s when I fight the best and these techniques help me to do that.”
Powell added that Mullally’s techniques were important in maximising the minute of rest in between rounds to slow heart rate and recover as quickly as possible.
