Calculated Maximum Heart Rate & Target Training Zone
Your calculated target heart rate, or the ideal intensity needed to improve
cardiovascular fitness, depends primarily upon your age rather than your
current state of fitness. If the exercise intensity is too low or too high, only
modest gains will be made in strength and cardio-vascular fitness. A workout
at a very low intensity will not offer maximum benefits. Conversely, if the
workout intensity is too high, injury or fatigue may slow the progression of your
exercise goals as the body attempts to recover.
Note: It is most effective to train at a heart rate between 60%
and 85% of your maximum heart rate. Maximum heart rate
is calculated as a percentage of your maximum heart rate
(estimated as 220 beats-per-minute minus your age).
To calculate your maximum heart rate and find the appropriate target training
zone, use the following formulas. For example, the following estimation would
be relevant for a 35 year-old user:
• 220 – 35 = 185 Bpm (220 – Age = Calculated Maximum Heart Rate in Beats-per-minute/Bpm)
• 0.60 x 185 = 111 Bpm (60% of 185 BPM [Calculated Maximum Heart Rate] = 111 Bpm)
• 0.85 x 185 = 157 Bpm (85% of 185 BPM [Calculated Maximum Heart Rate] = 157 Bpm)
