Explain two ways that can be used to monitor level of physical exertion
• Perceived Exertion. A method used to determine if a vigorous level of exertion has been attained is the perception of an activity feeling "somewhat hard" to "hard" as indicated by breathlessness and/or a fatigue level. Generally a physical effort should allow conversation, not singing, but if one is out of breath quickly or the activity must be stopped to catch breath, then the exertion is too much.
• Heart Rate. Another common method used to determine level of exertion is to measure heart rate during or immediately after exercise and compare that rate to a target heart rate or a target zone. Your target heart rate is your recommended heart rate for exercising. Some authorities prefer to recommend a range of heart rates to aim for when exercising referred to as a target zone.
