They applaud one hundred fast movers on track? (8)

'movers on track?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'they applaud one hundred' is the wordplay.
I cannot quite see how this works, but
'applaud' could be 'clap' (synonyms) and 'clap' is found within the answer.
The remaining letters 'pers' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'fast' acts as a link.

Can you help me to learn more?
