PRT Bike Equation Changes Mean More Accurate Results 

From Navy Personnel Command Public Affairs Office

MILLINGTON, Tenn. – The equation used to convert calories burned during the 12-minute Physical Readiness Test (PRT) stationary bike test will change Jan. 1, 2011, the Navy announced in a message Aug. 5.

According to NAVADMIN 256/10, the revised equation will more accurately calculate outstanding performance. It will also require the Sailor to burn more calories to achieve a probationary or satisfactory score on their PRT.

The only stationary bikes approved for use on the Physical Readiness Test are the Life Fitness 95CI and Classic Series and both are now on the online Physical Readiness Information Management System (PRIMS) calculator drop down menu. To access the bike calculator, go to the PRIMS homepage at
