Joseph Parker greets the crowd at an open workout in Cardiff ahead of his heavyweight championship bout with Anthony Joshua.
A body language expert said that Anthony Joshua may not be as confident as his appearance suggested at a recent press conference.
The British boxer, who currently holds the WBA, IBF and IBO belts, will face Parker on Sunday morning (NZT) in a heavyweight unification bout at Cardiff's sold out Principality Stadium.
In their final press conference yesterday, Joshua and Parker both beamed with confidence as they each promised their fans a knock-out.
However, body language expert Blanca Cobb said Joshua's demeanour revealed a very different range of emotions than his confident appearance suggested.
Speaking to the Daily Star Online, Cobb pointed out that when Joshua said Parker was "quick and could take a punch," the Brit rubbed his arm and pulled on his forearm.
"This suggests that he is feeling uncomfortable talking about Parker," Cobb said.
"When you're feeling stressed, your body finds a way to release anxiety and excess energy."
Cobb, who has appeared on numerous TV shows, said Joshua acted in a similar way when he talked about the possibility of losing to Parker.

Cobb also analysed Parker's body language, pointing out that when the kiwi boxer spoke of beating Joshua, he tugged at his jacket, revealing a sense of "uneasiness".
