Heart Rate
Heart Rate is the avearge number of heart beats per minute. It is important to know more about heart rate measurements and use the heart
rate charts to understand and help improve your overall cardio fitness.
1. What is Maximum Heart Rate
A Maximum Heart Rate (Max HR) is the highest number of beats your heart contracts within a minute. Max HR is useful when measuring
training intensity and level of exercise.
2. What is Resting Heart Rate
A Resting Heart Rate is the number of heart beats within a minute while you're at a completely rest state. This indicates your basic
overall heart health and fitness level.
3. What is a Heart Rate Zone
A Heart Rate Zone is a heart rate range that helps you maintain an intensity level while you work out. Different heart rate zones are for
different types of athletes and level of exercise you are following.
Next
Heart Rate Zone Intensity % of Maximum Heart Rate
1 Relaxed, easy pace; rhythmic breathing 50% - 60%
2 Comfortable pace; slightly deeper breathing, conversation
possible 60% - 70%
3 Moderate pace; more difficult to hold conversation 70% - 80%
4 Fast pace a bit uncomfortable; breathing forcefully 80% - 90%
5 Sprinting pace, unsustainable for long period of time; labored
breathing 90% - 100%
