mysql sql query needing to be written

im having issues with an sql statemetn

i have

select *

from analysis_heart_rate

where heart_rate_id between (heart_rate_id and heart_rate_id + 6)

and heart_rate_timestamp between (heart_rate_timestamp and TIMEDIFF(heart_rate_timestamp , "5:00") )

i have a database whcih records who is wearing a belt every second. basicallay i want, for a "belt_no", if i select a person wearing this belt at say 12midday, i want the belt being allocated to this person for the next five minutes. Given we are recording who is wearing a belt every second, there will be hundreds of records updated by selecting one person. So bascially every record from 12midday to 12:05 will automatically be allocated to this player.
