80% of Max heart rate ?

The cardio machines in the gym show my rate at age 50 is 144. I usally work at a harder pace. What is the correct formula for figuring what my heart rate should be at for a good cardio/aerobic workout? BTW I do a cardio for 55 to 60 minutes a day. Thankx.

Good question but you will get as many different answers as there is sources for this info.

Some people go by 220 - age x percent., 220 - 50 * .80 =136

I like the Karvonen Formula 220 - age - resting heart rate * percentage + resting heart rate.

Check you resting rate when you wake up in several mornings and average them.

Like the other posts stated, if you want a different formula just ask someone else. I took a fitness class several years ago and the instructor told us, not to worry about the numbers. He said if you are doing your work out and you are unable to carry on a verbal conversation with someone, you are working out anaerobically, if on the other hand, you can talk without gasping, you are working aerobically. Thoses charts are for a typical person, if you race motorcycles, your anything but typical. Just do your workout, if you feel good in the end you did everything right, if you feel spent afterwards you probably didn't do yourself much good. The other important thing we were taught was not to leave the exercise area without a proper cool down. Usually all that was needed was some floor stretching and deep breathing with isometric work to you target area.

excellent advice, and well stated. in my experience, most people overdo it when they are trying to work out aerobically.

I like this formula. http://www.stevenscreek.com/goodies/hr.shtml

I did a V02 max test a few months ago and the heart rate zones derived from that test closely matched what the formula predicted. I think it's close enough for us average Joe's and even the Pro's!

Calculated 80%-144 Same as Elliptical machine.

Max heart rate is meaningless:

Again, another tale I had told and people refused to believe. It's not difficult for track riders to get their heartrates well over 210bpm. Others would say it's impossible. No read this and remember that your legs go 140bpm at least when these rates happen!

MAXIMUM HEART RATE FORMULA IS WRONG

Gabe Mirkin, M.D.

Many of the standard tests used to measure heart function are based on a nonsensical MAXIMUM HEART RATE formula, that predicts the fastest your heart can beat and still pump blood through your body. Although this formula is the golden standard used today, it is not based on science. In 1970, a good friend, Sam Fox, was the director of the United States Public Health Service Program to Prevent heart disease. He is one of the most respected heart specialists in the world. He and a young researcher named William Haskell were flying to a meeting. They put together several studies comparing maximum heart rate and age. Sam Fox took out a pencil and plotted a graph of age verses maximum heart rate and said it looks like maximum heart rate is equal to 220 minus a person's age. For the last 30 years, this formula has been taught in physical education and heart function course and has been used to test heart function and athletic fitness. In the 1960s, Sam Fox was very helpful to me when I was competing, planning and setting up running programs, but the whole concept of maximum heart rate and the formula that it is equal to 220 minus your age is ridiculous.

The formula is wrong because your legs drive your heart. Your heart does not drive your legs. Maximum heart rate depends on the strength of your legs, not the strength of your heart. When you contract your leg muscles, they squeeze against the blood vessels near them to pump blood from your leg veins toward your heart. When your leg muscle relax, your leg veins fill with blood. So your leg muscles pump increased amounts of blood toward your heart. This increased blood fills the heart and causes your heart to be faster and with more force. This is called the Bainbridge reflex that doctors are taught in their first year of medical school. The stronger your legs are, the more blood they can pump, which causes your heart to beat faster. Since I race at my maximum speed most weekends on my bicycle, my legs are very strong and can pump blood forcibly to my heart. The formula, 220 minus age, claims that I can get my heart rate only up to 220 minus 66 or 154. I am 66 years old and I can easily get my heart rate above 210 beats a minute because I am in shape. An out-of-shape 20 year may have maximum heart rate of only 120.

A pencil mark plotted on a graph during an airplane flight more than 30 years ago has been the accepted formula for maximum heart rate for more than 30 years and the medical community has accepted false dogma, based on no research, for more than 30 years.
