What is the target heart rate for a 13 year old?

It used to be that the formula of 220 minus your age was the %26quot;gold standard.%26quot; But there is a growing school of thought that age-based formulas are not the best strategy.



Most methods are based on achieving targeted exertion levels (zones) defined by percentages of the maximum heart rate (Max HR).



Max HR is the highest heart-rate value achieved in an all-out effort to the point of exhaustion. Obviously, it閳ユ獨 rarely the goal of any workout to take you to a point of all-out exhaustion, but using percentages of a Max HR to determine the appropriate intensity for a given workout (or series of workouts) can help create more efficient and effective fitness routines. For example, working out at half the Max HR is great for improving health and increasing base level of fitness, while working out at 75 percent of Max HR is a great way to improve cardiovascular capacity and endurance.



But the best method for determining Max HR remains a hotly debated topic. The main problem is that Max HR is not influenced so much by age as by genetics. In fact, most people of similar age do not have the exact same Max HR.



There are basically three methods. Two of them require professional training equipment or resources. The following formula is the most reliable for do-it-yourselfers: Calculate 210 minus one-half your age; minus 5 percent of your body weight (in pounds); plus four (for men) or zero (for women). This formula has been tested on thousands of people and the results typically fall within five heartbeats of a person閳ユ獨 true Max HR. Of course, even this formula leaves something to be desired, but it beats the simple 閳?20 minus age閳?hands down. To calculate your target heart zone, multiply the Max HR number by 65% and then by 85%. That represents the target heart range.

I would think it is about 130 beats per minute.

Using the easier method (not knowing the resting heart rate)...



220- age= max heart rate.



Decide what percentage you want to have as your target, and multiply the target percentage (decimal format) and the max rate together. This gives you the target heart rate at that percentage.

Your target heart rate is specific to the desired benefit. Target heart rates are based off your maximum heart rate, which you cannot determine with any accuracy without have a stress test performed by a qualified facility.



Your maximum heart rate is highly individualized, and will vary from person to person. It does not change with age, it has nothing to do with your level of fitness, and it will vary depending on the activity you perform (it%26#039;s activity-specific).



One generic way of calculating your maximum heart rate is subtracting your age from 220. This is almost never accurate (unless by chance) and gives the impression that older individuals have lower maximum heart rates, which is not true.



It is, however, a VERY conservative estimate, and ensures that you do not exceed a safe level of intensity if you are just beginning a cardio routine. Shoot for 65-75% of this number for starters. More often than not, it will be very easy and you will have to challenge yourself a bit more to make progress.



Also, unless you are using an EKG accurate, chest-strap heart rate monitor, you will have no idea what heart rate you are actually working at (as you cannot go by how you %26quot;feel%26quot;).
