Summary

The purpose of this study is to examine the acute effect of continuous and aerobic interval exercise on postexercise central BP response in men with an elevated blood pressure.

Conditions

  • Exercise
  • Central Blood Pressure

Aerobic Interval Exercise

Subjects will perform an interval exercise bout on a cycle ergometer. To warm up, they will cycle at a work rate associated with 50% of their max heart rate (HR) for 10 minutes. Wattage will then increase and they will do four 4-minute intervals at a work rate associated with 90%-95% HRmax, separated by 3 minutes of active recovery at a work rate associated with 50% HRmax They will be given a 5-minute cool-down period at a work rate associated with 50% of their max HR. After the exercise, they will remain in the lab for 4 hours and their blood pressure will be measured every 10 minutes using an automated blood pressure monitor and cardiac output will be measured using the PhysioFlow. They will remain seated during this time

OTHER

Continuous exercise

Subjects will perform a 30-minute continuous exercise bout on a cycle ergometer. To warm up, they will cycle at a work rate associated with 50% of their max heart rate (HR) for 10 minutes. Wattage will then increase and they will perform a 30-minute exercise bout at a work rate associated with 75%-80% of their max HR. They will be given a 5-minute cool-down period at a work rate associated with 50% of their max HR. After the exercise, they will remain in the lab for 4 hours and their blood pressure will be measured every 10 minutes using an automated blood pressure monitor and cardiac output will be measured using the PhysioFlow. They will remain seated during this time.
