A response about training period (9)

I believe the answer is:
preseason
'training period' is the definition.
'preseason' can be an answer for 'period' (preseason is a kind of period). I'm not certain of the 'training' bit.
'a response about' is the wordplay.
'about' is an anagram indicator.
'a'+'response'='aresponse'
'aresponse' anagrammed gives 'PRESEASON'.
Can you help me to learn more?
(Other definitions for preseason that I've seen before include "before the play begins" , "Before league games begin" , "period before play starts" .)
