Mobster, senior man, regularly used martial art (8)

I believe the answer is:

capoeira

'martial art' is the definition.
(Brazilian martial art)

'mobster senior man regularly' is the wordplay.
'mobster' becomes 'capo' (term for a mafia leader).
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'senior'+'man'='seniorman'
The alternate letters of 'seniorman' are 'eira'.
'capo'+'eira'='CAPOEIRA'

'used' acts as a link.
