Beckham to captain LA Galaxy for first time since 2008
The ex-England skipper, 35, took the role upon joining in 2007 but in recent years Landon Donovan - currently on international duty - has been captain.
Donovan questioned Beckham's commitment to the club was by in 2009, while Galaxy fans booed Beckham for a period.
"I'll be proud to wear it," said Beckham of the captain's armband.
"It doesn't change the way I play. It's something you're very proud to wear, but you need more than one leader on the field."
Beckham relinquished the role to Donovan when he joined AC Milan on loan in 2009, missing the start of the MLS season in the process.
Galaxy manager Arena said the decision to turn back to Beckham, albeit on a one-off basis, was simple.
"He's a logical choice," he said.
"He's worn the captain's armband here before and probably in a couple of other places as well. I don't think it's asking too much. It's not too overwhelming for him."
