For each case study, you must develop an appropriate exercise
prescription. Use the FITT recommendations from the ACSM
guidelines. You will need to calculate a workload for the
particular type of mode of cardiovascular exercise you choose
utilizing the metabolic equations. Once you pick an appropriate
intensity, use the VO2R equation to calculate the oxygen
consumption. Then use that to solve for the workload on the
treadmill or cycle, whichever you think is best. Don't forget to
indicate frequency and duration...
