target heart rate zone
The prescribed range of heart rates at which a cardiac rehabilitation patient should exercise to achieve optimal training benefits safely.
Full Definition
Target heart rate zone is the specific range of heart rates, typically expressed as a percentage of maximum heart rate or heart rate reserve, within which a cardiac rehabilitation patient should exercise to achieve cardiovascular training benefits while maintaining safety. This zone is individualized based on the patient's exercise test results, medications (particularly beta-blockers), clinical status, and rehabilitation goals. The target zone is typically lower in early rehabilitation phases and may be adjusted throughout the program based on patient progress and exercise tolerance. Staying within this zone helps ensure adequate training stimulus while preventing overexertion.
Usage
Usage note: Hyphenate when used as compound adjective; use 'zone' rather than 'range' for precision.
